The increasing age of the population has raised the importance of determining the minimally required surgical treatment for elderly lung cancer patients. Despite a number of previous studies, the therapeutic impact of a radical mediastinal lymphadenectomy (RLA) associated with a pulmonary resection for lung cancer remains controversial. Herein, we investigated the impact of lymph node dissection on the overall survival for elderly lung cancer patients and assessed whether the non-performance of an RLA could be justified in the surgical treatment for these elderly patients.
