Curative management typically includes surgical resection, often with axillary lymph node dissection (ALND), followed by regional nodal radiotherapy.

The aim of this study was to evaluate survival determinants and the acute and long-term toxicities associated with second-course regional nodal irradiation as part of curative strategies for INR after localized breast cancer.</p><p><strong>Materials and methods: </strong>This retrospective study included 11 patients with localized breast cancer who developed ipsilateral, nonmetastatic INR between 2003 and 2019.
