Salvage Surgery After Definitive Chemoradiotherapy for Non-small Cell Lung Cancer

Following definitive chemoradiation therapy, 24%-35% of patients with locally advanced non-small cell lung cancer have recurrence. We aimed to evaluate the feasibility of salvage surgery after definitive chemoradiotherapy and perioperative morbidity and mortality rates to determine long-term survival. From June 2003 to June 2013, 35 patients were eligible for lung cancer resection owing to relapse after definitive chemoradiation therapy. All patients received cisplatin-based chemotherapy and definitive radiotherapy (mean Gy: 58) with curative intent and all underwent total body computed tomography scan and 18-fluoro-deoxyglucose positron emission tomography scan after the end of medical treatment and before surgery. Cyto-histologic confirmation was attempted in 20 (57%) patients. Six patients had exploratory thoracotomies. Twenty-nine patients underwent lung cancer resection: 11 lobectomies, 1 bilobectomy, and 17 pneumonectomies (7 right, 10 left). Complete resection was obtained in 27 of 35 (77%) patients. Thirteen (45%) patients underwent extended resection: intrapericardial pneumonectomy in 5 patients, vascular or bronchial sleeve resection in 2, atrial resection in 1, tracheal sleeve in 1, superior vena cava resection and reconstruction in 2 (1 with tracheal-sleeve resection), and chest wall resection in 2. Median time from chemoradiation therapy to resection was 7 months (range: 1-39). Viable tumor was found in 26 of 29 (89.6%) patients. Major complications occurred in 9 patients (25.7%). There were 2 (5.7%) perioperative deaths within 30 days. With a median follow-up of 13 months, postoperative 2- and 3-year survival rates after complete resection were 46% and 37%, respectively. Salvage lung resection after definitive chemoradiation therapy is feasible, with acceptable postoperative survival and complication rates.
