Tamoxifen or third generation aromotase inhibitor is recommended or administered within 1 year (365 days) of diagnosis for women with AJCC T1cN0M0 or stage IB-III hormone receptor positive breast cancer (Accountability) 90% 92.3 94.9 90.8

*Total of 3/19 patients received radiation, but occurred more than 1 year after diagnosis (Reasons: (a) 2 patients the decision was to add more chemo s/p neoadjuvant followed by mastectomy due to disease extension; (b) XRT delayed as a patient required an ostomy for an unrelated condition).
