Abstract
BACKGROUND.: The current study was conducted to examine the outcomes of pneumonectomy after induction chemoradiotherapy in patients with locally advanced nonsmall cell lung cancer (NSCLC).METHODS.: All patients undergoing pneumonectomy after induction therapy at the Brigham and Women's Hospital were retrospectively evaluated for 30‐day and 100‐day mortality and treatment‐related complications with Institutional Review Board approval. Multivariate and univariate analyses for clinical factors correlating with toxicity and/or survival were calculated.RESULTS.: Between 1995 and 2005, 73 patients underwent pneumonectomy for NSCLC after induction therapy. All patients received radiation (median dose of 54 gray [Gy]) and 69 patients (95%) received concurrent chemotherapy. The median age was 62 years and 43 patients (59%) were male; Thirty‐seven patients (51%) had American Joint Committee on Cancer stage IIIA NSCLC, 27 (37%) had stage IIIB, 6 had stage IIB, and 4 had stage IV NSCLC because of a resected solitary brain metastasis. A majority (44; 60%) of patients received the combination of carboplatin and paclitaxel, whereas 15 (21%) received the combination of cisplatin and etoposide. Forty‐five patients (62%) underwent left pneumonectomy. With a median follow‐up of 28 months, the 1‐year and 2‐year overall survival rates were 70% and 49%, respectively. The 30‐day and 100‐day mortality rates were 6% and 10%, respectively. Only 4 of 73 patients (6%) died of acute respiratory distress syndrome. The rate of nonfatal treatment‐related morbidity was 11%. On univariate analysis, right‐sided pneumonectomy was associated with a higher risk of treatment‐related mortality (P= .099).CONCLUSIONS.: With an acceptable mortality rate, a single‐institutional series demonstrated that trimodality therapy including pneumonectomy can be safely accomplished in patients with advanced NSCLC.
