The lymph node status and histologic subtypes influenced the effect of postoperative radiotherapy on patients with N2 positive IIIA non–small cell lung cancer

Abstract

For patients with completely resected IIIA-N2 NSCLC, mediastinal lymph node metastasis and histologic subtypes could influence the effect of PORT. Single N2 station involvement and papillary predominant subtype were predictors of benefit from PORT.
