Abstract

Background The role of surgical resection as a treatment option for early-stage small-cell lung cancer (SCLC) is controversial, and few data exist regarding the patterns of treatment failure in these patients. Patients and Methods The medical records of all patients receiving definitive surgical management of SCLC at Mayo Clinic (Rochester, MN) from January 1, 1985 to December 31, 2012 were reviewed. Estimates of survival and recurrence risk were recorded using the Kaplan-Meier method, and comparative analyses were performed with Cox regression analysis. Results A total of 54 patients were identified. The median follow-up period was 5.9 years. At 5 years, overall survival was 37% and recurrence-free survival 44%. Intrathoracic recurrence, the most frequent treatment failure, occurred in 14 patients, with an estimated intrathoracic recurrence-free survival at 3 years of 64.4%. Patients undergoing wedge resection or segmentectomy, rather than lobectomy or pneumonectomy, had an increased risk of intrathoracic recurrence (hazard ratio, 3.5; P =.01). Overall survival was improved at 5 years after lobectomy or pneumonectomy compared with wedge resection or segmentectomy (48% vs. 15%, respectively; P =.03). Conclusion Surgical resection of SCLC can achieve reasonable treatment outcomes and can be considered for well-selected patients with clinical early-stage disease. Intrathoracic recurrence is the most common site of treatment failure. Caution should be taken with patients who are unable to tolerate at least lobectomy, because they are at a high risk of local recurrence.
