Background: This study aims to evaluate long-term results of induction treatment and to investigate prognostic factors affecting survival in non-small cell lung cancer patients with a pathological complete response.

Methods: Between January 2010 and December 2017, a total of 39 patients (38 males, 1 female; mean age: 56.2±8.3 years; range, 38 to 77 years) having locally advanced (IIIA-IIIB) non-small cell lung cancer who were given induction treatment and underwent surgery after induction treatment and had a pathological complete response were retrospectively analyzed. Survival rates of the patients and prognostic factors of survival were analyzed.

Results: Clinical staging before induction treatment revealed Stage IIB, IIIA, and IIIB disease in three (7.7%), 26 (66.7%), and 10 (25.6%) patients, respectively. The five-year overall survival rate was 61.2%, and the disease-free survival rate was 55.1%. In nine (23.1%) patients, local and distant recurrences were detected in the postoperative period.

Conclusion: In patients with locally advanced non-small cell lung cancer undergoing surgery after induction treatment, the rates of pathological complete response are at considerable levels. In these patients, the five-year overall survival is quite satisfactory and the most important prognostic factor affecting overall survival is the presence of single-station N2.
