Abstract
Thoracoscopic lobectomy is well established for the treatment of early non-small cell lung cancer (NSCLC). Its safety and efficacy for advanced-stage disease remain uncertain. Between January 1, 2002, and July 31, 2007, a total of 125 patients were evaluated for thoracoscopic lobectomy for advanced NSCLC. Thoracoscopic lobectomy was completed in 73 patients. Eleven patients were excluded for extensive chest wall involvement. Open resection was performed in 41 patients, with 19 planned thoracotomies and 22 conversions from an initial thoracoscopic approach. Median operative blood loss, operation time, major complications, and hospital length of stay were all similar for patients undergoing thoracoscopic and open resection. A higher percentage of patients who underwent thoracoscopic lobectomy were able to receive adjuvant therapy compared to the open group (37.2% vs. 5.2%; P = 0.006). The differences between the thoracoscopic and open groups in overall survival (43.7 vs. 22.9 months; P = 0.59) and disease-free survival (34.7 vs. 16.7 months; P = 0.84) were not significant. Thoracoscopic lobectomy for advanced-stage NSCLC can be performed safely, with results equivalent to open techniques. With continued experience, lower morbidity with resections performed for advanced-stage disease by video-assisted thoracoscopic surgery will be expected, similar to that observed with early-stage disease. This is particularly important given the large number of frail patients with advanced-stage disease who require multimodal therapy.
