Surgical resection of limited disease small cell lung cancer in the new era of platinum chemotherapy: Its time has come.

Overview

abstract

OBJECTIVE: Although resection is not the standard of care in treating small cell lung cancer, new platinum drugs and modern staging have allowed the role of surgery to be reevaluated. METHODS: We reviewed our institutional experience of 1415 patients with small cell lung cancer from 1976 to 2002 among whom 82 (6%) underwent surgery with curative intent. RESULTS: Median age at surgery was 62 years, and small cell lung cancer of mixed morphology represented 14 of 82 (17%). Treatment consisted of surgery alone in 11% of cases (9/82), surgery with neoadjuvant therapy in 22% (18/82), and surgery with adjuvant therapy in 55% (45/82). Prophylactic cranial irradiation was given to 23% (19/82). The 5-year survival of the entire cohort was 42%. The 5-year survival of patients receiving adjuvant chemotherapy (n = 41) was significantly different according to whether patients had received platinum or nonplatinum regimens (68% vs 32.2%, P = .04). Among patients with stage I disease who received adjuvant chemotherapy (n = 24), the 5-year survivals for patients receiving platinum and nonplatinum chemotherapy were 86% and 42%, respectively ( P < .02). If patients who received either neoadjuvant or adjuvant therapy (n = 56) were considered, the 5-year survival was significantly better for platinum than for nonplatinum chemotherapy (62% vs 36%, P = .05). The 5-year survival was also better for those undergoing lobectomies (n = 52) than for those with limited resections (n = 15, 50% vs 20%, P = .03). Survival outcomes also differed by gender, with female patients having a 5-year survival advantage over male patients (60% vs 28%, P = .004). CONCLUSION: These results support a reevaluation of the role of surgery in the multimodality therapy for small cell lung cancer, which currently includes only radiotherapy and chemotherapy.
