Effect of postmastectomy radiotherapy on pT < sub > 1-2 < /sub > N < sub > 1 < /sub > breast cancer patients with different molecular subtypes

CONCLUSION: PMRT significantly reduced the LRR risk in patients with pT1-2N1 luminal and triple-negative breast cancers, but had no effect on the LRR risk in patients with HER2-overexpressing cancer. Patients with different molecular subtypes displayed different annual LRR patterns, and the late recurrence of the luminal subtype suggests the necessity of long-term follow-up to evaluate the efficacy of PMRT.PMID:34942430 | DOI:10.1016/j.breast.2021.12.013
