Definitive radiotherapy for hilar and/or mediastinal lymph node metastases after stereotactic body radiotherapy or surgery for stage I non-small cell lung cancer: 5-year results

Purpose The optimal treatment for hilar or mediastinal lymph node (LN) recurrence developing after stereotactic body radiotherapy (SBRT) for stage I non-small cell lung cancer remains unclear. This study evaluated 5-year results of radiotherapy in such patients in comparison with those for postoperative LN metastases.
