Published: November 2016 (Web posted September 2016)

Read Guideline Update

This focused update to the guideline on use of postmastectomy radiotherapy (PMRT) focuses on key areas of ongoing controversy, including the use of PMRT for patients with 1-3 positive lymph nodes or who are undergoing neoadjuvant systemic therapy; selected technical aspects of PMRT, particularly the extent of regional nodal irradiation; and whether PMRT is indicated in women with T1-2 tumors and a positive sentinel node biopsy who do not undergo completion axillary lymph node dissection.

Developed in collaboration with:

  • American Society for Radiation Oncology
  • American Society of Clinical Oncology
  • Society of Surgical Oncology

Key Points:

  • Use of postmastectomy radiotherapy
  • Decision-making using a multidisciplinary approach and patient involvement
  • Selected technical aspects of PMRT, particularly the extent of regional nodal irradiation
