Would you consider omitting PMRT in cT3N0 triple negative breast cancer with a pCR?

These are challenging cases with limited data as Dr. @Dr. First Last notes. In a young patient with cT3N0 disease with a pCR, I would discuss the lack of data and that RT may reduce rates of LRR with unclear survival benefits. I would discuss the pros and cons but I would be comfortable offering the...

There is a paucity of information on the risk of local-regional recurrence following mastectomy in patients following neoadjuvant chemotherapy (NACT). This is particularly so for those who present with clinical T3N0 cancers. The largest such cohort is from the NSABP B-18 and B-27 trials, performed f...
