Abstract

Objectives: To define the place for surgery in combined modality treatment of small cell lung cancer patients. The endpoint was: does complete resection reduce the risk of local failure?

Methods: Between November 1981 and June 1996, 75 patients in stage I--III A, many of them with a bulky cN2 tumor at presentation, were exposed to VP-16 based cytoreductive chemotherapy. After three courses of induction treatment, 46 patients underwent thoracotomy and 35 of them had resection.

Results: There were two sudden deaths (pulmonary embolism). No other complications were observed. In six cases (6/35 = 16%), no residual tumor was found in the resected specimen. Four weeks after surgery, chemotherapy was resumed. Three patients experienced local relapse (3/33), among them, the single patient with incomplete resection, and two other patients developed local and distant failure (2/33). Thus, the local relapse rate was 15% (5/33). Eight patients, mainly with chemotherapy induced surgicopathological complete remission (pCR) and with lymph nodes free of tumor in surgical specimens (pN0), are alive, tumor-free, at a median of 136 + months. Two patients died tumor-free at 65 and 147 months. One patient died of unrelated causes at 21 months with no evidence of disease at autopsy. The median survival in the cN0 + N1 subsets was 25.09 months, whereas in cN2 disease, this was 13.75 months. There were no long-term survivors among the patients with persistent N2 disease. The median survival in all 35 patients using the Kaplan--Meier method was 18 months; the 5-year tumor-free survival rate was 29% and the 10-year tumor-free survival rate was 23%.

Conclusions: Satisfactory local tumor control confirmed the assumption of the study. No residual tumor in the resected specimen (pCR) is the most favorable prognostic factor and determinant of long-term survival. Surgery should not be performed in the patients with persistent N2 disease.
