- 00:00For joining us tonight on this
- 00:03evening is a smaller shares a lecture.
- 00:06Tonight we will be discussing and lymphoma
- 00:10understanding new treatment advances.
- 00:13So for many of you who may not know me,
- 00:15I'm suddenly and one of the uncommon
- 00:18medical oncologist at Greenwich
- 00:20Hospital Smilow Cancer Center.
- 00:22And we are very happy and privileged
- 00:25to have doctor Francine files and
- 00:28Doctor Francesco Montanari joining us.
- 00:30Dr Fauci is a professor medicine in
- 00:32the section of medical oncology at
- 00:34the Yale Cancer Center and she is an
- 00:37internationally recognized clinician and
- 00:39clinical researcher with expertise in
- 00:42adult lymphoma and in stem Cell Alley.
- 00:45Transported transplantation,
- 00:46she has dried and tested therapies
- 00:49that have been used to treat thousands
- 00:52of cancer patients.
- 00:53And her research has potential
- 00:55to substantially impact the field
- 00:58of stem cell research benefiting
- 01:00patients at Yale and around the world.
- 01:03That our own Dr.
- 01:04Mountain Airy joined the our Smile
- 01:06of Kansas Hospital here at Greenwich
- 01:09at last year's.
- 01:10She's an assistant professor of
- 01:12clinical medicine and cares for
- 01:14patients with hematologic malignancies
- 01:16and she joined us from Columbia.
- 01:19Columbia Presbyterian Medical Center.
- 01:22Well,
- 01:22she was an assistant professor of
- 01:25medicine and experimental therapeutics.
- 01:27She received her medical degree
- 01:29from University of Pavia and she
- 01:32where she graduated Magna ***
- 01:34Lauda and completed her residency
- 01:36and fellowship at New University,
- 01:39where she was awarded the
- 01:40fellow Year Teaching award so.
- 01:42A few housekeeping tips before
- 01:46we get started,
- 01:48we would like everybody to be make sure
- 01:49that they're muted throughout the event.
- 01:51Once we start,
- 01:52we welcome you to ask questions by typing,
- 01:55typing them into the Q&A button
- 01:57at the bottom of your screen.
- 01:59At any point in the lecture,
- 02:00and we will save some time at the
- 02:02end to answer those questions.
- 02:04Thank you very much for joining us and
- 02:07let's allow me to get get get it started.
- 02:21So lymphoma, then farmers are cancer
- 02:23of or from the lymphatic system.
- 02:27It is a relatively uncommon cancer from the
- 02:31annual incidence is about 81,000 new cases.
- 02:35That makes up about 4% of all new cancer
- 02:38cases in our country and approximately
- 02:4120,000 people are projected to die
- 02:44from this illness this year alone.
- 02:47So this is just a diagram of what
- 02:50a lymphatic system looks like.
- 02:53I'd like to say that the lymphatic
- 02:55system anyway mirrors our circulatory
- 02:57system that covers our entire body.
- 03:00Unlike circuit or system,
- 03:01though it doesn't have a center.
- 03:03You know for the circuit or system is
- 03:05a heart that's the center of it all.
- 03:06Instead of lymphatic system,
- 03:08have few key organs such as the
- 03:10spleen and the famous and the bone
- 03:13marrow which is not included here.
- 03:15And I kind of like.
- 03:17To look at it as a like a subway
- 03:19map of the New York City are
- 03:22covering the entire surface.
- 03:24Start covering the entire
- 03:26body with nodes like stations.
- 03:29And cancel that can develop cancer
- 03:31that develops anywhere in the
- 03:34lymphatic system would be a lymphoma.
- 03:36And as Doctor Fauci will discuss,
- 03:39not only can the cancers
- 03:41developing these lymphatic glands,
- 03:42but they can also be found in our
- 03:45skin as well as mucosal services.
- 03:48And because of surfaces are
- 03:49parts of our body that come into
- 03:51contact with the outside.
- 03:55When we Christians think about informal,
- 03:57we divide them broadly into two
- 03:59separate groups, Hodgkin's lymphoma
- 04:01and non Hodgkin's lymphoma.
- 04:03Essentially in a simplistic way based on
- 04:05where their former selves derived from on
- 04:08this evening will be discussing mainly
- 04:11on about the non Hodgkin's lymphoma.
- 04:14And then on houses in the former can be
- 04:17further divided into B cell lymphoma,
- 04:19T cell lymphoma.
- 04:19And I, I suppose third category would be
- 04:23something called NK natural killer cell.
- 04:26Killer cells the that these two
- 04:31Doctor Montanari will discuss the
- 04:33advances in B cell lymphoma and doctor
- 04:36Fossil discussed AT cell lymphoma.
- 04:39Just a quick word before.
- 04:42We start our discussion.
- 04:45As many of you may know,
- 04:47chemotherapy has been utilized the
- 04:50treatment of malignancies for UM.
- 04:54I suppose since the 1950s and until 1997,
- 04:59treatment for lymphoma has been
- 05:01fairly consistent.
- 05:02Component made up of similar type
- 05:05of non specific medication that
- 05:07at times could be very toxic,
- 05:09toxic and in 1997 a new way of treating
- 05:13the foremost developed a medication
- 05:16called Rituxan overtaxing map and
- 05:19thereafter many new advances in our
- 05:21call in oncology and specific treatment of.
- 05:24The former has followed and
- 05:26now without further ado,
- 05:28I'd like to present Dr Monk Montanari,
- 05:30who will discuss abuse,
- 05:32such offences, NPC lymphoma.
- 05:37I share my screen. So that we can be we want.
- 05:46Perfect so uhm. I will go through.
- 05:51Then a new treatment
- 05:53advances for visa lymphoma.
- 05:55Uh, my will start just briefly revealing
- 05:57the classification of non Hodgkin lymphoma,
- 05:59and then we'll review the treatment
- 06:01paradigm and what's new for aggressive
- 06:03in England lymphoma and right now
- 06:06we're using the word that organization
- 06:09classification from 2016 and this
- 06:12is the device for the addition.
- 06:14There are over 60 subtypes of non Hodgkin
- 06:18lymphoma and at every provision new.
- 06:21Subtypes are added up.
- 06:23I just went up up.
- 06:25I got your attention that if you start
- 06:29with selling common follicular lymphoma
- 06:31this only these two types constitute
- 06:33more than 50% of non Hodgkin lymphoma
- 06:37and therefore the other subtypes.
- 06:40The numbers for the other subtypes
- 06:42gets smaller and smaller in red.
- 06:44I highlighted the T cell lymphomas
- 06:46which are much more uncommon than
- 06:49the visa and when we think about.
- 06:52Lymphoma.
- 06:53We think about aggressive lymphoma and
- 06:56England comma and this is important
- 06:59repercussion on the treatment paradigms.
- 07:02And so when we talk about
- 07:04aggressive lymphoma,
- 07:05we think about lymphoma that are
- 07:08potentially curable with the
- 07:10intensive immunochemotherapy and
- 07:12sometimes a consideration with
- 07:15autologous stem cell transplant.
- 07:16These are lymphoma that poison an
- 07:19immediate threat to patients life
- 07:22and need to be aggressively treated
- 07:24and when the most common of these
- 07:27aggressive lymphoma is diffuse,
- 07:29large B cell lymphoma, that alone.
- 07:32And constitute a third of all
- 07:35that non Hodgkin lymphoma.
- 07:37Uhm, says the most common subtype.
- 07:39This is only something funny about
- 07:4125,000 cases per year in EU S and
- 07:44is usually diagnosed in stage 4.
- 07:47We are usually considered historic
- 07:50stratify patients based on design,
- 07:53international prognostic index based on
- 07:55age and the age at presentation performance,
- 07:58status stage,
- 07:59and number of extranodal disease
- 08:02psych you see, prognosis varies,
- 08:05and it is excellent for patients
- 08:08with that low risk disease.
- 08:1091% patients are alive for year
- 08:13after and potentially cured up.
- 08:16This number gets lower and
- 08:17lower with additional.
- 08:18Factors that we need to make things
- 08:22a little bit more complicated.
- 08:23Now we know that if you start to be selling,
- 08:25former doesn't come in one flavor through
- 08:28the utilization of gene expression profile.
- 08:31We know that we have germinal Center
- 08:33B cell like lymphoma and activity,
- 08:35peaceful life.
- 08:36That's two main categories of diffusers,
- 08:39Mr Lymphoma,
- 08:40that at the expression of different genes
- 08:42and that translate in a different behavior.
- 08:44These are survival curves based on
- 08:47germinal center and activity missile
- 08:49like and as you see Germinal Center.
- 08:51Time to do better with current treatments.
- 08:56As Doctor Lee mentioned at the beginning,
- 08:59the treatment paradigm for lymphoma and
- 09:03is relatively old chop chemotherapy.
- 09:06They want we currently use for these
- 09:09subtypes of disease has been introduced
- 09:11in 1976 and it was not until 1997.
- 09:15Then the taxing on the first
- 09:18UM monoclonal antibody,
- 09:19the first targeted drug for cancer.
- 09:22Was approved as you see here.
- 09:24Clearly taxi map.
- 09:25These are the overall survival.
- 09:27Curves are based on the
- 09:29international prognostic score.
- 09:31The risk factors that I showed you
- 09:33before and after the taxi model.
- 09:35This survival costs have
- 09:37been lifted up nicely,
- 09:39but since then several efforts
- 09:41have been done to improve further,
- 09:43more disturbed, and they did not
- 09:46translate into a new standard of treatment.
- 09:49Uh, there have been studies
- 09:52comparing more intensive.
- 09:54Treatment chemotherapy treatment options such
- 09:56as those adjusted on April compared to CHOP.
- 10:00There have been attempts to
- 10:02incorporate targeted new targeted
- 10:03agents into the arch of a backbone,
- 10:06but all these studies didn't
- 10:07translate in a in a benefit,
- 10:10and therefore, as of 2021,
- 10:13this current standard of
- 10:14care remain are chopped up.
- 10:17There's a lot of expectation from
- 10:19the upcoming American Society of
- 10:21Hematology meeting regarding the
- 10:23staff regarding the results of a.
- 10:25Studies comparing your child with
- 10:28a newer targeted drug with R.
- 10:30Chop the polarised rider,
- 10:32but it does not start not out yet.
- 10:35Uhm, beyond first line of treatment.
- 10:38So patients that do not respond
- 10:40or relapse after first line can
- 10:43still be cure and typically about
- 10:4420 to 40 patients can cure can
- 10:47be heard with the chemotherapy,
- 10:49such as the platinum based or
- 10:52gemcitabine based chemotherapy and
- 10:55autologous stem cell transplant.
- 10:57But unfortunately only a minority
- 10:58of patients end up liking receiving
- 11:01this intensive chemotherapy treatment
- 11:03because of age or comorbidities.
- 11:05Patients who do not respond to
- 11:07summer sterope or relapse after
- 11:09the Alex Cancer transplant are
- 11:11very likely to die from lymphoma,
- 11:14so a lot of research has been done
- 11:17to provide more options to this
- 11:20patient and over the past five years.
- 11:23A lot of new option had been
- 11:25approved as you see.
- 11:27Here at summarized cymatic antigen receptor,
- 11:30T cell three products have been
- 11:33approved since 2017 and then there
- 11:37are newer drugs targeted drugs.
- 11:40Three of them are monoclonal antibodies,
- 11:42two of which are antibody drug
- 11:44conjugated and one is a small molecule,
- 11:48and we'll see a little bit more in details.
- 11:50What are these cameras?
- 11:52Antigen receptor T cells?
- 11:53Essentially,
- 11:54these artists from patients
- 11:56that are collected.
- 11:58From and isolated from the blood of patients,
- 12:00they are sent to facility
- 12:02where they're sorted.
- 12:03The engineer the utilizing an active
- 12:06virus to insert genes and to make
- 12:09them express a special receptor that
- 12:12is called the car and undersurface.
- 12:15Then B cells are extended.
- 12:17Patient receive an immunosuppressive
- 12:19treatment in preparation of receiving
- 12:22these cells to create a favorable
- 12:25environment for this out to tribe.
- 12:28And then the sound was there,
- 12:29infused in the body.
- 12:31A targeted cancer cell and caused
- 12:34the death on the the cancer cell.
- 12:37Nice,
- 12:38some.
- 12:38Some of these cells are able to persist in
- 12:41the body for some for a period of time,
- 12:43helping with immunosurveillance.
- 12:45So this is a really knew technology.
- 12:49And since the approval of the
- 12:52first party product back in 2017,
- 12:54which is a second generation,
- 12:56newer cars have been approved.
- 12:593rd Generation CARS,
- 13:00which differs from the second
- 13:03generation essentially in the
- 13:05costimulatory as signal and they are
- 13:08less and less toxic compared to the
- 13:11first to the first product which was.
- 13:15Diffusion of diskarte can be
- 13:17complicated by very severe cytokine
- 13:20release syndrome and neurotoxicity.
- 13:22Uhm, but they are able to really
- 13:26achieve greater results in patients
- 13:29that are otherwise refractory.
- 13:31With every factory overlaps disease,
- 13:34yet therefore tracks that I mentioned to
- 13:37you up are these at this for for drugs here
- 13:41three or monoclonal antibodies? As I said,
- 13:45this is the loading and understood.
- 13:49Special antibodies are smarter way to deliver
- 13:52inside the cancer cell chemotherapy there.
- 13:54What we call antibody,
- 13:56drug conjugate and essentially the
- 13:58the drug binds to the surface of
- 14:01the cancer cell gets internalized.
- 14:04Lisa Zone released the chemotherapy
- 14:06agent in the case of political map.
- 14:09Is that microtubule disruption agent
- 14:11and that caused a doses of this style.
- 14:14In the case of longest, took them up,
- 14:16is an alkylating agent,
- 14:17so similar mechanism of action different.
- 14:20Uhm, different target that is see them
- 14:22up is a antibody and that is a similar
- 14:25tour attacks in having that is not
- 14:28drug conjugated and Target City 19
- 14:30this is the same target of the party
- 14:33and Salinas are is an interesting new
- 14:36drug that works totally different
- 14:38and different way targeted a nuclear
- 14:41expert protein and that is a media
- 14:44is one of the mechanisms of Uncle
- 14:47Genesis and it's preventing diffusers.
- 14:50Comma, but also in multiple myeloma.
- 14:53So lot of new option that have been
- 14:55recently approved in a matter of
- 14:57two years for diffuse large B cell
- 14:59lymphoma under flaps refractory
- 15:01standing up if we shift gears we're
- 15:03going to talk about what is.
- 15:05What are the treatment
- 15:06paradigm for England lymphoma.
- 15:08So in a little informal trade different
- 15:11approach to these are incurable disease
- 15:14and these are diseases that patients are
- 15:18gonna live with and probably die with.
- 15:21But not die from and.
- 15:23So the purpose of treatment is to
- 15:26minimize succeed city associated to
- 15:28treatment and maximize the quality
- 15:31of life producing to the minimum.
- 15:33The toxicity.
- 15:36Particular lymphoma accounts for 22%
- 15:41of all information this than most
- 15:43common in violently thrown out there,
- 15:45and the most common treatment
- 15:47strategies for indolent lymphoma,
- 15:50particularly comma in particular,
- 15:51is watch and wait, active surveillance.
- 15:54We usually do not treat patients unless
- 15:58they have they meet specific criteria
- 16:01which refer to as Gulf Gulf criteria.
- 16:05These are the group 2 the
- 16:06link from follicular.
- 16:07Criteria and essentially this criteria
- 16:09based on the bulk of disease on the
- 16:13presence of symptoms or end organ damage
- 16:16in the absence of a buddies indication,
- 16:19patients are monitored conservatively.
- 16:21One exception is stage one disease.
- 16:25It's very rare to diagnose Allen
- 16:28film and stage one, and in that
- 16:31instance radiotherapy can be curative.
- 16:34Uhm?
- 16:34These are typical approach.
- 16:37Chemotherapy immunochemotherapy
- 16:38approaches that we use as first line
- 16:41treatment for indolent lymphoma.
- 16:43Once the patient meets this criteria.
- 16:46Bendamustine rituximab is a very
- 16:48common regiment that is utilizes
- 16:50less toxic than our chop.
- 16:52Patients do not lose their hair
- 16:55and it costs less
- 16:57milotic city and the instructions.
- 17:00Newer version of rituximab and it utilizes
- 17:03alone or in combination with chemotherapy.
- 17:06And then there are platforms
- 17:08that are chemotherapy.
- 17:09Freeman taxonomically Delight is a
- 17:11good option as a frontline treatment
- 17:14for indolent lymphoma based on
- 17:16their relevance pastry trial data.
- 17:19Once the patient completes induction then
- 17:22we typically perform maintenance with
- 17:25anti CD 20 every three months for two years.
- 17:29This has been shown to prolong the
- 17:32remission from first line treatment.
- 17:34But that's not have a big
- 17:36impact on the overall survival,
- 17:38and therefore now in the time in the
- 17:40COVID era we are limiting the use of
- 17:43maintenance with anti CD 20 antibody
- 17:46because these are the antibody
- 17:48that this antibiotic can cause.
- 17:50I took an ugly Nina can wipe out the
- 17:53good antibody that patients mount after
- 17:55receiving the vaccine for COVID and poise.
- 17:58Higher risk of infection beyond first line.
- 18:01So follicular lymphoma,
- 18:03the Natural History of England.
- 18:05Common follicular lymphoma is
- 18:07characterized by multiple relapses.
- 18:09The duration of Response Times progressively
- 18:12to decrease after each line of treatment.
- 18:16There is a particular subset of
- 18:19patients which accounts for probably
- 18:2120% of the total and that presents a
- 18:24relapse of disease within 24 months
- 18:27from the first line and this group we
- 18:30referred to as POD 24 disorder patient.
- 18:33There is a lot of research.
- 18:35Going on for first of all to try
- 18:38to the United,
- 18:39identify them up front and then
- 18:41to create a treatment paradigm
- 18:44to improve their prognosis.
- 18:46But in general subsegment treatment
- 18:49option for follicular England lymphoma
- 18:51include another combination of an anti CD
- 18:5420 antibody plus or minus chemotherapy.
- 18:57We tend to utilize the same
- 19:00agents rarely on leave.
- 19:02The remission has been really long standing,
- 19:05otherwise we try to alternate views
- 19:07of the anti CD 20 antibodies and
- 19:10different forms of chemotherapy and
- 19:12then learn a little might are square
- 19:14Lendl made it as if it was not used up.
- 19:17Trump is a good option beyond Firstline
- 19:21knew advanced in this field have
- 19:24been done for third line agents.
- 19:27We have noble agents that RPI 3K
- 19:30inhibitors ezh 2 inhibitors and that
- 19:33Carty also are an option for these
- 19:36patients beyond the second line.
- 19:38So briefly, PI3K inhibitor.
- 19:40This is one of the most important pathway,
- 19:45a most important intracellular pathway.
- 19:47A master regulator for cancer is
- 19:49downstream from the cell receptor,
- 19:52and since 2014 until most recently
- 19:54for drugs have been approved,
- 19:57three or or one is intravenous
- 19:59and the last one on release it.
- 20:01It's a little bit different
- 20:03because it's also targets.
- 20:04Also seeking one accident,
- 20:06but we have a lot of options that.
- 20:09To target this pathway,
- 20:11another pathway that has been targeted
- 20:14is that ezh 2 ezh 2 is gonna be
- 20:17genetical regulator of gene expression
- 20:19is very important is crucial for
- 20:22the normal B cell biology and for
- 20:25the germinal center formation.
- 20:27A mutation in these each two
- 20:30suppressed the axis of the visa from
- 20:34the germinal center and lock the
- 20:36selling business state and so.
- 20:39Blocking the each two activity
- 20:42resumed the differentiation of the
- 20:45B cell and allow up to system,
- 20:47and this is an oral drug that has
- 20:49been recently approved in 2020,
- 20:51giving another option for patients
- 20:53with follicular lymphoma.
- 20:55And, as I mentioned before,
- 20:56Carti have been recently approved in
- 20:59March for patients with follicular
- 21:01lymphoma beyond second line
- 21:03beyond second line of treatment.
- 21:08I just wanna mention briefly,
- 21:10mantle cell lymphoma A.
- 21:12It's a very rare subtype of lymphoma.
- 21:15It constitutes only 6%
- 21:17of non Hodgkin lymphoma.
- 21:19To retract simitli UM fifty
- 21:2250,000 cases per year,
- 21:2555,000 cases prettier in EU S.
- 21:27And to make things a little
- 21:29bit more complicated,
- 21:30comes in four different variants
- 21:32which we identify based on the
- 21:35proliferation index and biased allergy
- 21:38and independent mechanic violent,
- 21:40we treat as follicular lymphoma and CLL,
- 21:44but the blast site and aggressive
- 21:48varien require aggressive treatment.
- 21:50We use combination of immuno chemotherapy
- 21:52followed by intelligence concept
- 21:54transplant and 9320 maintenance.
- 21:58After a few patients with that in the past,
- 22:02we didn't have any option because
- 22:04when this disease relapses
- 22:06usually chemo refractory but most
- 22:08recently starting in 2013 drugs
- 22:11to target the Bruton kinase tiles
- 22:14and kindness have been developed.
- 22:17This is an important pathway
- 22:18downstream from the B cell receptor.
- 22:21That mantle cell income is very sensitive
- 22:23to and also chronic lymphocytic leukemia.
- 22:26Cursor generation on BK.
- 22:28Emitter approved was brutally in 2013
- 22:31and shortly after other two second
- 22:34generation of collaborative events
- 22:36and Brittany but been approved.
- 22:38The beauty of the second generation
- 22:41drugs is that they have a less of
- 22:44targeted fact and the the cardio
- 22:47toxicity that was one of the limiting.
- 22:50Side effect of being routinely
- 22:52as substantially decreased within
- 22:54newer generation.
- 22:55Uh,
- 22:56there is a newer drug which is
- 22:58called peer to Brewton if it's still
- 23:00in clinical trial with the name of
- 23:03Laakso 305 and is about to be approved,
- 23:05it is a bit like a mini bitter but
- 23:07works a little bit different than
- 23:09the prior one and the beauty of this
- 23:11drug is that is much better tolerated.
- 23:16I'm gonna finish here.
- 23:18I just want to highlight that all
- 23:22the new drugs that we discussed and
- 23:25this is this is all these drugs
- 23:28have been approved and received.
- 23:30An accelerated FDA approval based on
- 23:32the results of phase two clinical
- 23:35trials and it is crucial to encourage.
- 23:39You can research in this field not
- 23:41only to improve our current treatment
- 23:43paradigm and to deepen our knowledge
- 23:45of specific disease,
- 23:47but also with the purpose to increase
- 23:49survival of our patients with
- 23:51employment to improve their quality of life.
- 23:56And with this. I'm gonna
- 24:00stop shooting my screen.
- 24:21App. I think you're muted Doctor Lee.
- 24:25We cannot hear you, sorry. Well,
- 24:28thank you very much,
- 24:29Doctor Montanari and that was fantastic
- 24:31and now we will switch over to Doctor
- 24:35Fauci who is where as I said earlier,
- 24:38is a world leader in treatment of
- 24:40T seven former so doctor fast.
- 24:42If you could tell us So what makes
- 24:44T cell lymphoma different than
- 24:46be something formal, deductive,
- 24:48imaginary had discussed earlier?
- 24:51Well, Doctor Lee actually everything
- 24:53up makes T cell lymphoma different.
- 24:55They'd be selling phomma.
- 24:57It's harder to treat.
- 24:59It's rare and you know there are
- 25:01many different clinical issues
- 25:03that patients run into that are
- 25:05slightly different than B cell.
- 25:07So I'd like to go ahead and do a
- 25:09brief presentation and I'll try to
- 25:11touch on some of the key points.
- 25:13Can we get the next slide?
- 25:16Renee.
- 25:21Uh, OK. I think I might be able to
- 25:24advance them, so I just want to start
- 25:27off by saying that T cell lymphoma
- 25:30is a rare disease and a rare disease
- 25:33requires a center of excellence,
- 25:35really, for optimal treatment.
- 25:37For patients, the group at Yale does
- 25:40represent the center of excellence.
- 25:42For TSO Info, Ma and I just want to point
- 25:44out to all the patients and the folks
- 25:47listening in the audience that it's
- 25:48not just the doctors that you see here.
- 25:51Today, giving you this talk that
- 25:53contribute and help to take care
- 25:55of you that play a critical role
- 25:57in your care in the Cancer Center.
- 25:59Because there are many faces behind
- 26:01the scenes that are also critical
- 26:03and important to us.
- 26:04On this slide you see the path
- 26:07ologist such as Doctor Hsu,
- 26:09Dr Katz and Doctor Braddock who are
- 26:11the folks that actually look at your
- 26:14slides and make the diagnosis of lymphoma.
- 26:16And they also help us to subtype the
- 26:19type of lymphoma and oftentimes.
- 26:21They do immunostains to identify markers
- 26:24that help us to treat Doctor Kai is
- 26:27in the PET scan department here at Yale.
- 26:31The diagnostic imaging Group and of course,
- 26:34PET scans are critical to follow
- 26:35your disease as well as to diagnose
- 26:38the sites of lymphoma in your body
- 26:40and Doctor Chi is working with us to
- 26:42develop some novel ways to use PET
- 26:45scanning to actually detect residual
- 26:47disease after chemotherapy and then
- 26:50of course we have the clinical team.
- 26:51Myself, Doctor Sethi and Doctor Montanari,
- 26:55who is presenting today and then
- 26:57we also have the research group in
- 26:59the background.
- 27:00We have Doctor Marcus,
- 27:02musician and doctor Elias
- 27:03Loulis who are only two of many,
- 27:06many folks who are working in basic
- 27:09science laboratories studying your tissue,
- 27:11getting samples of blood and tumor
- 27:13tissue and studying various animal
- 27:15models of lymphoma to try to
- 27:17come up with novel therapies.
- 27:19So really this is a team approach.
- 27:22Next slide.
- 27:25So AT cell lymphoma I'll be at rare
- 27:28is actually increasing in incidence,
- 27:31so unlike B cells lymphoma where
- 27:32there are close to about 70,000 cases
- 27:35in the United States there's only
- 27:37about 9000 cases of T cell lymphoma,
- 27:40and there are a number of different
- 27:42reasons why tastes Alabama might
- 27:44be increasing.
- 27:44The first reason may be due to our
- 27:48pathology colleagues who have developed
- 27:50techniques to make the diagnosis in
- 27:52cases where it might be confusing.
- 27:55In some cases T cell lymphomas
- 27:57can look like be selling farmers,
- 27:59and they can also look like
- 28:00Hodgkin's disease.
- 28:01So I think some of the increase in incidents
- 28:03is related just to better diagnosis.
- 28:06But we also know that certain viruses,
- 28:08such as the EBV virus and the
- 28:11HTLV one virus which is found in
- 28:13the Mediterranean and in Japan,
- 28:15can be associated with T cell
- 28:18lymphoma and also the hepatitis
- 28:20virus and the HIV virus as well
- 28:22various chemicals in our atmosphere.
- 28:25Chemicals in our food.
- 28:27Agent Orange,
- 28:27which is dioxin perhaps also
- 28:30contribute to lymphoma in general,
- 28:32as do immunosuppressive drugs that are
- 28:34now being used for a lot of different
- 28:37autoimmune diseases such as rheumatoid,
- 28:39arthritis, psoriasis, and colitis.
- 28:40Some of these diseases affect your immune
- 28:44system in a way where various kinds
- 28:46of lymphomas could actually spring up.
- 28:49Celiac sprue is a disease where folks
- 28:52basically can't eat wheat because they
- 28:54have sensitivity to gluten and in patients.
- 28:57With celiac sprue, there isn't an
- 28:59incidence of intestinal T cell lymphoma.
- 29:01I'll be it rare and then finally I think the
- 29:05most common causes random genetic mutations.
- 29:08Of course, every cancer patient who comes
- 29:10in wants to know how did I get this cancer?
- 29:13What did I do wrong?
- 29:15But the bottom line is that you probably
- 29:17didn't do anything wrong because many
- 29:19of these are just random mutations that
- 29:21occur and those mutations accumulate
- 29:23and they end up causing cancer.
- 29:26Uh, next slide.
- 29:29So clinical features of T cell boamah
- 29:32and Doctor Lee alluded to this in his
- 29:35introduction. He selling bombers.
- 29:37Unlike BSO lymphomas like to go
- 29:39to different tissues in your body.
- 29:41In fact,
- 29:42if you look at various tissues in your body,
- 29:44there are normal T cells within those
- 29:47tissues and those normal T cells
- 29:49are there to protect you against
- 29:51foreign antigens and infections.
- 29:53So they're basically fighters and
- 29:55soldiers that are protecting your
- 29:57body and they're in the skin.
- 30:00The GI system, such as your intestines,
- 30:03the liver,
- 30:04and the spleen in your nose and
- 30:06in your sinus is,
- 30:07and therefore T salambo miss
- 30:09could arise in any of these sites.
- 30:11So one common site is the skin,
- 30:14but I mentioned the intestinal T
- 30:16cell lymphoma in celiac sprue.
- 30:18The sinus is and the oral cavity can
- 30:21be involved in NK T cell lymphoma
- 30:23and then the liver and the spleen
- 30:26in hepatosplenic T cell lymphoma.
- 30:28But pretty much any organ in the
- 30:30body can be involved.
- 30:32And if you look at skin involvement,
- 30:33about 45% of the patients who have
- 30:36lymphoma in this skin have a condition
- 30:38called cutaneous T cell lymphoma,
- 30:40which is mycosis fungus or the
- 30:43Sezary syndrome and then also I
- 30:46mentioned that different viruses,
- 30:47and in particular the EBV virus
- 30:50can cause the extranodal NK T cell
- 30:53lymphomas that occur in your sinus
- 30:55is and a disease called the Angel
- 30:58immuno blastic to self oma as well
- 31:00as others and next slide.
- 31:03Shows you that TICA lymphomas can
- 31:06masquerade in the clinic as a number of
- 31:09other different entities or diseases.
- 31:11For instance,
- 31:11you may or may not have heard of
- 31:14him at oh phagocytosis,
- 31:15which is a condition where you basically
- 31:17have fevers and low blood counts,
- 31:19and that is oftentimes seen with two
- 31:22solemn phomma abdominal pain and
- 31:24perforation can be seen in patients
- 31:26who have intestinal T cell lymphoma,
- 31:29enlarged liver and spleen in hepatosplenic,
- 31:32as well as other types.
- 31:34Vasculitis or autoimmune disease can
- 31:36oftentimes be the first presentation
- 31:39of angioimmunoblastic T cell lymphoma
- 31:42and a high calcium level can be seen,
- 31:45in particular with the HTLV
- 31:47one associated T cell leukemia,
- 31:49but also other types of
- 31:50T cell lymphoma as well.
- 31:52Kidney failure can occur with
- 31:54different types of T cell lymphoma.
- 31:56We can see cardiac arrhythmias happening
- 31:59and of course various kinds of skin rashes.
- 32:02So oftentimes a patient.
- 32:04He selling former will present.
- 32:08With one of these symptoms
- 32:10and then eventually,
- 32:11the diagnosis is made next slide.
- 32:16Uh, this site just shows you that many
- 32:19different clinical manifestations,
- 32:20patients with various skin lesions.
- 32:23You can see this gentleman with
- 32:24a tumor at the roof of his mouth.
- 32:27Below that you can see the lining of
- 32:29the intestine which is involved with
- 32:32T cell lymphoma under the microscope
- 32:34on the opposite side you can see
- 32:36circulating leukemia cells and you
- 32:38can see various other skin manifests.
- 32:40Manifestations that ISE lymphomas are
- 32:43broken down in the classification system.
- 32:47Based on how they present clinically,
- 32:49if they present primarily in lymph nodes,
- 32:51they're the nodal group.
- 32:53If they present it in the skin there,
- 32:55the cutaneous group.
- 32:56If they present in these various
- 32:59extranodal sites,
- 33:00they fall into that extranodal
- 33:02category and then finally some
- 33:03of them are leukemic where they
- 33:06predominantly have circulating cells
- 33:08in the blood and the next slide.
- 33:12Shows you the complete classification of T
- 33:15cell lymphomas and you can see there are lot
- 33:19of different subtypes of T cell Oklahoma.
- 33:21So one thing to be careful about if you
- 33:23have a T cell lymphoma and you're doing
- 33:26some reading about this disease is to
- 33:28look more specifically at what type you
- 33:30have because some of these are indolent
- 33:32and some of them are more aggressive.
- 33:35As Doctor Montinari alluded to.
- 33:37With B cell lymphoma there are many,
- 33:39many different types.
- 33:40Then they have different clinical behavior.
- 33:42But overall, the most common type of T cell
- 33:45lymphoma are these nodal T cell lymphomas,
- 33:48and that's in the box.
- 33:50You can see that that includes PTCLNOS,
- 33:54which is peripheral T cell
- 33:56lymphoma not otherwise specified.
- 33:58Angioimmunoblastic T cell lymphoma
- 34:01anaplastic large T cell lymphoma,
- 34:04which is ALCL that could be
- 34:06out positive or alk negative,
- 34:08and then the follicular helper and nodal
- 34:11follicular helper type of T cell lymphoma.
- 34:13So that comprises a significant
- 34:15number of our cases,
- 34:17the next slide.
- 34:19Gives you an idea of the distribution
- 34:22of these different subtypes,
- 34:23and Doctor Montanari showed you
- 34:25this for B cell lymphoma as well.
- 34:27You can see that peripheral
- 34:29T cell lymphoma in the blue,
- 34:30the angioimmunoblastic in the red
- 34:33are the two most common types.
- 34:36The anaplastic large cell lymphomas are
- 34:39shown in the in the purple at 5 and 6%.
- 34:42Then you have those NK T cell
- 34:45lymphomas presenting in the sinus
- 34:47is the skin and the nasal cavity.
- 34:50And then in the light,
- 34:52the light green color is adult T
- 34:55cell leukemia lymphoma which is
- 34:57associated with that HTLV one virus.
- 34:59But the thing to notice about this
- 35:01is that many of these T solid foam
- 35:04is are very infrequent, 1 to 3%.
- 35:06As you can see on the on the left
- 35:10side of this circle. The next slide.
- 35:15Uhm,
- 35:15it shows you the cutaneous T cell lymphomas,
- 35:18and I'll just say one word about
- 35:21this disease because Yale is one of
- 35:23about eight or nine centers in the
- 35:25United States that sees many patients
- 35:28with cutaneous T cell lymphoma.
- 35:30We have total skin radiation
- 35:33therapy available,
- 35:34which is only available in a handful
- 35:36of places around the country.
- 35:38And that's a key treatment for
- 35:40this disease as well as expertise
- 35:42in dermatology with Doctor Edelson
- 35:44and Doctor Gerardi.
- 35:45Who are both world leaders in this
- 35:48area and myself and my colleagues.
- 35:51Dr.
- 35:51Dr.
- 35:52Sethi and Martin Montanari,
- 35:53as well as our bone marrow
- 35:56transplant colleagues who see many
- 35:58patients with this disease.
- 35:59So cutaneous T cell lymphomas
- 36:01can occur in the skin.
- 36:03They can be patches or plaques.
- 36:05They can be hyper or hypopigmented.
- 36:08They can occur as tumors as you
- 36:10can see on this gentleman space,
- 36:13or they can occur as redness
- 36:15all over your body.
- 36:16Which is called the Sezary syndrome.
- 36:18And again,
- 36:19this is the most common type
- 36:21of T cell lymphoma involving
- 36:23the skin the next slide.
- 36:28The next slide alludes to
- 36:31what Doctor Montinari very,
- 36:32very elegantly talked to you about
- 36:34with B cell lymphoma and that is
- 36:37that in order to treat these diseases
- 36:39effectively we need to really hone
- 36:41in on what the molecular problems
- 36:43are and we need to develop drugs
- 36:46that can specifically reverse
- 36:48those specific molecular issues
- 36:49that we find in the tumor.
- 36:52So there are multiple pathways that
- 36:55are aberrant or overexpressed,
- 36:57or perhaps mutated.
- 36:59That contribute to the malignancy
- 37:01in lymphoma and and many of those
- 37:03are shown on this slide and the
- 37:05important point for this slide and
- 37:07the reason I'm showing it to you
- 37:10is that we actually have developed
- 37:12a program that targets many of
- 37:14these different abnormalities and
- 37:16some of the drugs that we have
- 37:18in clinical trials are shown on
- 37:20the left hand side of the slide.
- 37:22I won't go into them in detail,
- 37:25but many of these are early stage studies.
- 37:28Phase one such as the Cobra Marson.
- 37:31Where we actually were among the first
- 37:33centers to put this into people as a
- 37:36kind of first in man the tipifarnib,
- 37:38I'll show you a slide to show
- 37:40you a responder in that trial,
- 37:43and then several of these others as well.
- 37:46Some of these such as TIGIT are novel
- 37:48immuno therapies that attacked the
- 37:50actual the T cells that are preventing
- 37:53our body from having an immune response.
- 37:56So all of these are important and
- 37:58again clinical trials are critical.
- 38:01To the understanding of the disease
- 38:03and to developing novel therapies.
- 38:05Next slide. It shows you why.
- 38:09Perhaps you should consider
- 38:11participating in a clinical trial,
- 38:13so this is one of our patients
- 38:15with aggressive T cell lymphoma.
- 38:16The peripheral T cell lymphoma
- 38:18not otherwise specified.
- 38:20He had advanced stage four disease.
- 38:22He had our conventional chemotherapy,
- 38:24which is the first line treatment
- 38:26for lymphoma.
- 38:27As you heard from Doctor Montinari,
- 38:29the chop type regimen is our
- 38:32kind of our standard therapy,
- 38:34so this gentleman had that treatment
- 38:35and then he developed progression.
- 38:37In his skin,
- 38:38and if you can look at the pet
- 38:40the pet scan at baseline,
- 38:41all of those those white dots that
- 38:43you see on the arms and the legs
- 38:46are cancer cells within the skin.
- 38:48So this gentleman has very
- 38:50extensive involvement.
- 38:51He got the tipifarnib,
- 38:53which by the way,
- 38:54is an oral therapy that you basically
- 38:56just take the pill every day and
- 38:58he had a near complete response.
- 39:00After eight weeks you can see that
- 39:03second pet scan showing that almost
- 39:05all of these spots have gone away.
- 39:08In only eight weeks,
- 39:09and then subsequently,
- 39:11as he got more therapy,
- 39:12had a complete clinical response
- 39:14to this drug,
- 39:15and he moved on to transplant.
- 39:17So again we have some very
- 39:19impressive impressive therapies
- 39:20that were developing the next slide.
- 39:24Shows you that in addition to
- 39:26looking at those pathways,
- 39:28we're also doing molecular studies were
- 39:31actually sequencing these tumors to try
- 39:34to identify mutations that can be targeted
- 39:36again by new drugs and new approaches,
- 39:39and so by doing sequencing on many tumors,
- 39:42what we've learned is that there
- 39:45are certain pathways that seemed to
- 39:47be a barent in many patients with
- 39:49specific types of T cell lymphoma.
- 39:51So in the follicular helper T cell lymphoma.
- 39:54Such as Angioimmunoblastic and other types
- 39:57of follicular helper T cell lymphoma.
- 40:00You can look at the red bar across
- 40:02the top and you can see that just
- 40:05about every patient actually had
- 40:07a mutation in this Step 2 gene and
- 40:09then below that in the blue you can
- 40:12see another gene DNMT three.
- 40:14These jeans are what we call epigenetic
- 40:17genes and we interestingly have
- 40:19treatments that we can actually use
- 40:22to target these gene mutations.
- 40:25In these patients,
- 40:26and when we know that and we direct
- 40:28specific therapies to those patients,
- 40:30we actually can get very impressive
- 40:33clinical responses. The next slide.
- 40:36Showed you some work that Doctor
- 40:39Montinari did while she was still in
- 40:41New York before she came to Yale,
- 40:43so she was working with these
- 40:46epigenetic mutations and using
- 40:48drugs like ROMIDEPSIN and a society
- 40:51Dean to target those mutations.
- 40:53And so she was participating in
- 40:56the T cell consortium,
- 40:57which is a grouping of investigators
- 41:00around the world who are developing
- 41:02novel platforms to treat TICA lymphoma
- 41:05using primarily immunotherapy.
- 41:07And in this case you can see that
- 41:09there are combining multiple drugs
- 41:11and again all of these drugs,
- 41:13such as azacitidine, romidepsin, develop mab.
- 41:18These are all drugs that are immunotherapy's,
- 41:22not specifically chemotherapy.
- 41:24And again,
- 41:25they're targeting what we know are the
- 41:27molecular aberrations in these tumor cells.
- 41:30So this is really very exciting for
- 41:32us and the future of treatment of T
- 41:35cell info may in fact be chemo free
- 41:37Doctor Moncton. Ari has brought this.
- 41:39To us here at Yale,
- 41:41and we're about to actually get
- 41:43these trials open. Next slide.
- 41:47Just briefly,
- 41:47to talk about stem cell transplant
- 41:49stem cell transplant.
- 41:50You heard about for B cell.
- 41:52Lymphoma plays a critical role
- 41:54in relapse patients.
- 41:56Autologous transplant involves taking
- 41:57your own cells and then giving them
- 42:00back after high dose chemotherapy,
- 42:02and this is actually used in T cell
- 42:05lymphoma as part of the frontline therapy.
- 42:08So when you're first present you get
- 42:10your chemotherapy and then if you
- 42:12have a good response to chemotherapy,
- 42:14we would try to do an autologous
- 42:16stem cell transplant.
- 42:17And that would hopefully prolong
- 42:19their time that you're in remission.
- 42:21The autologous transplant can also
- 42:23be used if you've relapsed.
- 42:25If you didn't have it as part of
- 42:27your frontline therapy,
- 42:29and then finally allogeneic transplant,
- 42:32which involves getting donor cells
- 42:34from somebody else, a family member,
- 42:36or an unrelated donor from the
- 42:38bone marrow transplant registry,
- 42:40which is an international registry
- 42:42of folks who are volunteering
- 42:43to give you their bone
- 42:45marrow or their stem cells.
- 42:46The allogeneic transplant.
- 42:48Is often used for patients with T
- 42:51cell lymphoma who have relapsed after
- 42:54autologous transplant but also is is
- 42:57used sometimes as a first transplant.
- 42:59For patients with some of those very
- 43:01aggressive types of T cell lymphoma
- 43:03and allogeneic transplant is now
- 43:05being used for patients with mycosis
- 43:08fungoides and the Sezary syndrome.
- 43:10Those cutaneous T cell lymphomas we
- 43:12have a very large experience using
- 43:15transplant in Tucson Phomma at Yale.
- 43:18And we're we've published some of our
- 43:21data which actually looks pretty good.
- 43:23So both are tollison allogeneic
- 43:25transplant are ways that we can
- 43:27cure patients with two solid
- 43:29phomma and then the last slide.
- 43:33I'm sorry the the next slide shows
- 43:36that what happens if you actually do
- 43:38allogeneic transplant for T cell info.
- 43:39More patients,
- 43:40so this is actually a study that was
- 43:44done with many transplant and T cell
- 43:46lymphoma centers around the country.
- 43:48We all put all of our patients
- 43:51together and we looked at the outcomes
- 43:53and you can see again that if you
- 43:56look at that round pie chart you
- 43:58can see that it's pretty similar to
- 44:00what I showed you at the beginning.
- 44:02Many of these.
- 44:03Patients had peripheral T cell lymphoma,
- 44:05angioimmunoblastic and cutaneous T
- 44:07cell lymphoma and you can see that
- 44:11about 50% of these patients are still
- 44:14alive at five years and so effectively,
- 44:17that means that we've cured 50%
- 44:19of patients with T cell afoma
- 44:22with alginic transplant,
- 44:23and I think this is really great news for us.
- 44:26In great news for patients as well,
- 44:28what's what what we are doing now
- 44:31to try to improve on that 50%?
- 44:33Is we're using other treatments
- 44:36after transplant?
- 44:37Hoping to try to augment the effect
- 44:39of the transplant so that patients
- 44:41actually do better in the long run.
- 44:44And finally,
- 44:45the last slide talks about car T cell.
- 44:48You taught you.
- 44:49You heard about car T cell from
- 44:51Doctor Montanari and again,
- 44:53CAR T cell is approved for a B cell lymphoma.
- 44:56It is not yet approved by the FDA
- 44:58for T cell lymphoma and there are
- 45:01two different types of car therapy.
- 45:04What you heard about from Doctor
- 45:06Montanari is where we take the
- 45:08patient's own cells.
- 45:09We take those cells out by a
- 45:12pheresis and and then we.
- 45:14Engineer those cells by injecting a
- 45:17specific gene protein into those cells,
- 45:19and then we give them back to
- 45:21the patient in this whole process
- 45:23takes about three or four weeks.
- 45:25A newer approach is to use what
- 45:28we call allogeneic T cells,
- 45:30and that's shown on the bottom of this slide.
- 45:32What we do is we get healthy donors.
- 45:34We take their T cells,
- 45:36we inject the gene and we manipulate
- 45:39those T cells so that we can give
- 45:41them back basically to any donor
- 45:43and they won't get.
- 45:45Projected so those are what
- 45:47we call off the shelf T cells.
- 45:49Basically,
- 45:50once we identify a patient
- 45:51who might need that
- 45:53kind of a car, T cell therapy,
- 45:55all we need to do is call the company
- 45:57order their T cells have them delivered,
- 46:00which is generally fairly quick and then
- 46:02go ahead and give them to the patients.
- 46:04So I think this is exciting for
- 46:07the future and right now this is a
- 46:10clinical trial that is open at Yale
- 46:13for patients with T cell lymphoma.
- 46:16So I think that is my last slide and I
- 46:18believe will stop here for questions.
- 46:20I'll turn it back over to Doctor Lee.
- 46:23Great, thank you very much.
- 46:24That was fantastic and it really is exciting
- 46:27and I just want to echo our two speakers.
- 46:30And you know all these advances and
- 46:33and come through research and also on
- 46:36the research that are being done all
- 46:38over and of course and hours just yell
- 46:42in particular and we need researchers.
- 46:45When patients population and we need to
- 46:48support and one of the things that we
- 46:50hope to be able to offer is that with
- 46:53our hopefully new Cancer Center and
- 46:56they will have investigational trials.
- 46:58And then I made available to our community
- 47:01and our patients in our in our area.
- 47:04We've got a number of wonderful
- 47:06questions and Dr Mountain Airy has
- 47:07I think I answered some of them,
- 47:08but I have a, you know,
- 47:10given the age that we live in and I'd
- 47:13like to ask the two of you a couple of
- 47:16questions about COVID and vaccination
- 47:18so you know among your patients at your
- 47:21tree for B cell and Forman T cell lymphoma.
- 47:25My first question would be shooed
- 47:26are of course I'm going to send them.
- 47:29Our pictures have received and
- 47:31then the vaccine.
- 47:32Should they be receiving
- 47:33a booster vaccine and if.
- 47:34Yes,
- 47:35when should they receive it?
- 47:40Oh I, I can start with the, UM,
- 47:42you know we shall inform are the most
- 47:45common treatment that we most common
- 47:47drugs that we use are antecedent
- 47:49while yet monoclonal antibodies.
- 47:51And these are the cells that depletes this
- 47:54other produce antibodies in our body.
- 47:56So these are excellent treatment
- 47:58for the lymphoma.
- 47:59But the downside is that they sort of
- 48:03target the same sound that should protect
- 48:05us from from from from the COVID so.
- 48:09Patients, yes.
- 48:10Should that country receive
- 48:13vision will have cancer diagnosis.
- 48:15Solid organ transplant recipient
- 48:17and patient actively on treatment
- 48:20should be should receive a booster
- 48:22and and that is that is really
- 48:26important to maximize their their
- 48:29production against the bias.
- 48:32And I also think that we don't understand
- 48:35enough yet because we're so early in
- 48:38the evolution of COVID to understand
- 48:40what really constitutes a good a good
- 48:43immune response against the virus.
- 48:44As Doctor Montanari mentioned,
- 48:46antibodies are critical,
- 48:48but also we know that T cells play a very
- 48:50important role and many of our therapies.
- 48:53Of course, for two Salama deplete T cells
- 48:56so our patients oftentimes asked me,
- 48:58well, can I just get that COVID
- 49:00antibody level drawn in?
- 49:01Is that going to tell me weather?
- 49:02Whether or not I need a booster
- 49:04and and you know, I've talked
- 49:06extensively to our infectious disease,
- 49:08folks about that as well.
- 49:09And the answer is that we actually
- 49:12don't know yet whether those antibody
- 49:14titers really mean anything.
- 49:16And if a patient is immunocompromised
- 49:18and there as you said, a cancer patient,
- 49:22the harm in getting a booster
- 49:24is probably minimal.
- 49:25The benefit is unknown,
- 49:27so I generally recommend that
- 49:28patients do get the booster.
- 49:31Fantastic thank you very much.
- 49:33So I have one of the
- 49:36questions from our audience.
- 49:40I think will direct us
- 49:41back to mountain airy.
- 49:42Do we know what causes B
- 49:45cell follicular lymphoma?
- 49:46Or maybe you know you could.
- 49:48Are there any known risk factors
- 49:49for follicular B cell lymphoma?
- 49:53Made in China.
- 49:54Lisa risk factors for calling for.
- 49:56In general, anything that essentially
- 49:59triggers the immune system,
- 50:01so chronic infection there is a
- 50:04long list of viruses, bacteria that
- 50:07have been implicated in lymphoma,
- 50:09Genesis and more from for marginal
- 50:12zone infamous subtypes than than
- 50:15fully pellicular landform itself,
- 50:17but other neon diseases where your
- 50:21immune system is dysregulated.
- 50:24Their setup,
- 50:25they make patients more susceptible
- 50:28to develop lymphoproliferative
- 50:30disorder and finally also
- 50:33immunosuppressive treatment.
- 50:34So these are all risk factors
- 50:38specifically for particular lymphoma.
- 50:41There has not been any specific
- 50:44virus or bacteria implicated in
- 50:46the pathogenesis and as of 2021.
- 50:52OK, thank you. I have another
- 50:54question and this is for Doctor Foss.
- 50:57Here's a patient.
- 50:58It's president asking the
- 51:00question I believe is a patient.
- 51:02What role does age play in selection
- 51:04being selected for stem cell therapy?
- 51:07I am 76 and I've been led to believe
- 51:10that I'm too old for stem cell therapy.
- 51:13Well, you're absolutely not too old for
- 51:15stem cell therapy because I have a number
- 51:18of patients who are in their mid 70s
- 51:20who've had very successful allogeneic
- 51:22stem cell transplants. So excuse me,
- 51:24we don't actually go by age anymore.
- 51:27We go by what we call a comorbidity score,
- 51:31which involves basically
- 51:32assessing how good your heart,
- 51:34your lungs, your kidneys do.
- 51:36You have diabetes.
- 51:38Do you have other medical problems?
- 51:40And we kind of take all those
- 51:42factors into consideration.
- 51:43And so really the decision is made
- 51:46based on not based on your age,
- 51:48but based on your overall health situation.
- 51:52Thank you very much and you know this
- 51:54next question for Doctor Montana.
- 51:56I think we were addressed it but
- 51:57I just want to make sure that this
- 52:00question is clear since someone
- 52:01the artist is asking so I will
- 52:04rephrase this question as someone
- 52:05waiting a stem cell transplant for
- 52:09diffuse large B cell lymphoma.
- 52:11Should I get a booster?
- 52:13Will it meaning?
- 52:14The booster would be wiped out by the
- 52:16process of the stem cell transplant?
- 52:20So this is one of the
- 52:23instances where we we might
- 52:24decide to hold off the booster,
- 52:26especially if the transplant is imminent,
- 52:28because even after the booster
- 52:30it will require approximately two
- 52:32or three weeks for your immune
- 52:34system to mount a response,
- 52:35and by then if you're undergoing the
- 52:38intensive chemotherapy and transplant,
- 52:40you might lose the benefit.
- 52:42Typically, we do recommend to be vaccinated.
- 52:47After the transplant,
- 52:48that when your immune reconstitution
- 52:51happens approximately 3 months
- 52:53after the stem cell transplant,
- 52:55that's when we do generally recommend
- 52:56for patient to undergo vaccination.
- 53:00And also something I just wanted to mention.
- 53:03It's critically important in these situations
- 53:05for family members to be vaccinated.
- 53:08We've run into that in our transplant
- 53:10clinic and a couple of instances where
- 53:13some of the family members have not
- 53:16been vaccinated and we discussed the
- 53:17importance of that for the for the patient,
- 53:20for their loved one.
- 53:21Who's going to be immunocompromised for,
- 53:24you know, months and months.
- 53:25So we really like to stress that to families
- 53:28that you play a critical role as well.
- 53:31Thank you, that's great.
- 53:32I'm glad that you said that.
- 53:35This next question goes
- 53:37to Doctor Fauci again.
- 53:39And I, I believe you've asked
- 53:41this in your lecture, but again,
- 53:43I'm really question how does car T
- 53:46therapy work if you're healthy now.
- 53:48But if you relapse down the road,
- 53:51can you have your own cells taken at
- 53:53the time of relapse or do you need to
- 53:55have them taken while you're healthy?
- 53:59Are we talking about car T cell
- 54:01or stem cell transplant party?
- 54:03We do not. I mean,
- 54:05it's an interesting concept,
- 54:07but we actually do not take your
- 54:09own T cells unless you're sick.
- 54:12You know with lymphoma and about
- 54:14to undergo the car T cell process
- 54:17primarily because this cost involved
- 54:19and there's storage or freezing of
- 54:21the cells may affect the viability
- 54:23of the cells may or may not be as
- 54:25good when we need them down the road.
- 54:27So the answer to the question is.
- 54:29This moment in time we're not doing that.
- 54:33OK, next question is reflected lymphoma.
- 54:38Euro stated that follicular lymphoma
- 54:40has multiple relapses and measured OK.
- 54:43Is there also a certain percentage of
- 54:45patients where no relapse happened?
- 54:47I? I guess the question is asked in
- 54:49person is asking what percentage of
- 54:51people who guess who get a follicular
- 54:53lymphoma treatment will never relapse
- 54:55after the first round of treatment.
- 54:58Yeah, so we typically think about
- 55:00follicular lymphoma is incurable,
- 55:02infamous chronic disease where
- 55:04multiple relapses typically happen
- 55:06in the lifetime of patients.
- 55:08UM, stage one is would be additional
- 55:11would be an exception for that because in
- 55:14those instances in those rare instances.
- 55:17It could be curative,
- 55:19but typically we do expect the disease
- 55:21to come back at a certain point.
- 55:24For certain patients,
- 55:25the tile from treatment until the
- 55:28recurrence can be very, very long.
- 55:31It can be decades and the patient
- 55:35might have other medical problems that
- 55:38will ultimately be more important
- 55:40than the particular lymphoma,
- 55:42but we don't keep think about for
- 55:44determining format, typically cured,
- 55:46curveball,
- 55:47kind of kind of lymphoma with treatment.
- 55:51OK, yeah.
- 55:54Thank you
- 55:55and this. This is a very straightforward
- 55:58question and I believe there's answer
- 56:00can be sell the former patients undergo
- 56:02stem cell transplant and I think as we
- 56:04discussed in in in our lecture that
- 56:07investing is the answer's resounding yes.
- 56:09But again, you know it depends
- 56:11on your performance status.
- 56:12You know how you're in.
- 56:15So, uhm. Doctor fast,
- 56:18this question comes from someone
- 56:20that you and I know quite well
- 56:23and she asked how will you notify
- 56:25your patience if they are a good
- 56:27candidate for the upcoming trial.
- 56:29For patients with T cell T cell lymphoma.
- 56:35Exception is if someone is still has a
- 56:37T seven former and undergoing treatment.
- 56:40How can a patient find out that they may be
- 56:43eligible for an investigational therapy?
- 56:45You know, it's let's see if they are
- 56:47not a patient of our practice, how can
- 56:48someone find out if they are eligible?
- 56:50What? What is the typical process?
- 56:53So if a patient is being seen in
- 56:54any one of our our care centers,
- 56:56anyone of the smile care centers
- 56:58were all attuned to what those
- 57:00clinical trials are and we all have
- 57:02a list that we can refer to an.
- 57:04And it's online. In fact, on the on,
- 57:07the Yale Cancer Center website you can
- 57:10actually access what these trials are.
- 57:12You can ask your physician.
- 57:14You can always call in and
- 57:16and talk to to any one of us.
- 57:18We get calls all the time from folks
- 57:20who want to know more about the trials
- 57:22and it might be eligible for them.
- 57:24We are always screening patients because
- 57:26we obviously want to give give these
- 57:28novel therapies to people who need them,
- 57:30so we're always screening patients to
- 57:32see whether or not they are eligible.
- 57:34Patients may not realize it,
- 57:36but often times before we go in the room,
- 57:38we're talking in the backroom about
- 57:40the trials and, you know, looking at.
- 57:43Various factors like maybe the
- 57:44crap needs to hire you.
- 57:46You know your heart isn't functioning
- 57:47well or you know other issues that
- 57:49might exclude you from the trials,
- 57:51but the bottom line is that there there's
- 57:55information online available to you,
- 57:57and you're welcome to call and talk
- 57:59to anybody at any of the care centers
- 58:01at any time to access the information
- 58:03about the trials would certainly love
- 58:05to hear from anybody who wants more
- 58:07information about clinical trials.
- 58:10And thank you for the fast.
- 58:11I think that's absolutely right that
- 58:14that many patients really don't realize
- 58:16that behind the scene your clinician,
- 58:19the research coordinators,
- 58:21we're all reviewing the records
- 58:23and to consider whether that person
- 58:25can be better served through one
- 58:27of the investigational trial.
- 58:28And of course,
- 58:30simply just asking us would be,
- 58:32you know, we work to come as
- 58:34the time is running out of this.
- 58:36If there's one more question,
- 58:38I think the last question.
- 58:40If IMBRUVICA only works
- 58:41for two to three years,
- 58:43what kind of a treatment is
- 58:44possible for be selling former?
- 58:46After I think Dr.
- 58:47Mountain area answered that,
- 58:48but I'll let her take another
- 58:50crack at this question.
- 58:52Thank you so improving outcome.
- 58:55Hopefully it's gonna work for more
- 58:57than two to three years for most of
- 58:59the patient it has been approved in
- 59:022013 and there are questions that
- 59:04are still on the drug from 2013
- 59:06and now with benefit problem that
- 59:09sometimes these drugs long term can be
- 59:13associated with side effects and there
- 59:15is a drop half due to adverse event.
- 59:18Luckily to newer drugs have been
- 59:21developed after IMBRUVICA too.
- 59:22Sort of offset that problem there
- 59:25with glass of target effects.
- 59:27I mean, try to minimize side effects
- 59:29and making the drug more tolerable and
- 59:32then mentioned there is a new very,
- 59:34very interesting drug that is probably
- 59:37become available soon and just the last
- 59:40three or five that works similarly
- 59:42and has a better toxicity profile.
- 59:45So we have option.
- 59:47Great, thank you very much and I
- 59:50believe this brings still close.
- 59:52Thank you very much Doctor
- 59:53Foss doctor Martin Eric this is
- 59:55great and I hope our audience
- 59:57really got something out of it.
- 59:59So thank you everybody.
- 01:00:01Thank you. Thank you. Bye bye.
