Practice Point
Radiation therapy of the internal mammary lymph node chain
For patients where involvement of the internal mammary lymph nodes is identified during sentinel node biopsy or an 18F-FDG PET study, consider radiation to the internal mammary lymph node chain.
'Moderate' confidence that the recommendation reflects the net effect of a given course of action
How this guidance was developed
The extent of nodal irradiation is an area of ongoing debate and research (ACS/ASTRO/SSO 2016 Focused guideline update on postmastectomy radiotherapy).
This practice point was developed using an expert consensus process. A potentially relevant ‘moderate’ (using ASCO methods) source recommendation was identified from the ASCO/ASTRO/SSO 2016 guidelines (US) that provided guidance regarding radiation therapy of the nodal regions. This recommendation was not adopted or adapted because it was considered too detailed.
