Background: Advanced stage non-small cell lung cancer (NSCLC) is a fatal disease, characterized by mediastinal lymph node involvement (N2) and/or locally advanced tumor. In these patients the role of surgical resection—combined with induction treatment—remains controversial. We aimed to assess the clinical outcome of patients undergoing induction chemo- or chemoradiotherapy for N2 positive NSCLC.

Methods: We retrospectively reviewed the medical files of all consecutive patients undergoing induction chemo- or chemoradiotherapy followed by curative resection for N2 positive NSCLC between 1998 and 2013 at our institution.

Results: A total of 79 patients with N2 positive NSCLC received induction chemo- (n=36, 46%) or chemoradiotherapy (n=43, 54%) followed by radical surgery. The patients comprised 57 (72%) men and 22 (28%) women with a mean age of 58.5 years at the time of resection. Five sublobar resections, 44 lobectomies, five bilobectomies, and 25 pneumonectomies were performed. In 74 (93%) patients a complete resection (R0) was achieved. The 30-day morbidity and mortality were 26% and 1.3%. Overall 3- and 5-year survival rates were 66% and 54%, respectively. Overall disease free survival (DFS) will be presented at the conference. There was no difference in survival between patients receiving induction chemo- or chemoradiation (P=0.29).

Conclusions: Within a trimodality therapy including radical surgery favorable results for selected patients with N2 positive NSCLC can be achieved. Further prospective randomized trials are needed in order to investigate the value of radical resection in these patients.
