Effect of initial resection of small-cell carcinoma of the lung: a review of Southwest Oncology Group Study 7628.
The role of surgery in small-cell carcinoma of the lung (SCCL) has been recently re-evaluated. We reviewed the records of 262 patients with limited SCCL on Southwest Oncology Group (SWOG) protocol 7628. Fifteen patients were identified who presented after surgical resection (12 lobectomy, three pneumonectomy). All patients were subsequently treated with chemotherapy, radiotherapy +/- immunotherapy (BCG). Median survival time was 10.5 months. Median survival time of patients with initial surgical resection was 25 months (P = .004). Forty-five percent of the surgical patients were alive at two years v 13.7% of the nonsurgical patients (P less than .05). A second subgroup of 33 patients was identified with small primary tumors who did not undergo surgical resection. Median survival time in this group was ten months (P = .03). Site of initial relapse was clearly documented in 142 patients. Fifty-six percent of patients not receiving surgery had initial relapse within the chest compared to 13% of patients undergoing surgery (P = .002). Whether the survival benefit identified was caused by or was incidental to surgical resection of the primary lesion remains to be determined in randomized prospective trials of operable candidates.
