Should postmastectomy radiotherapy to the chest wall and regional lymph nodes be standard for patients with 1-3 positive lymph nodes?

Abstract

The indication for adjuvant postmastectomy radiotherapy (PMRT) in breast cancer patients with small tumors and 1-3 macrometastases in the axilla remains a controversial issue, despite the recommendation that PMRT should be applied in these patients in the most recent overview by the Early Breast Cancer Trialists' Collaborative Group. In this report, we discuss the available data on the benefit from PMRT in patients diagnosed with N1 breast cancer. Based on this, we recommend adjuvant PMRT to the chest wall and regional lymph nodes in patients diagnosed with early node-positive breast cancer. © 2011 S. Karger GmbH, Freiburg.
