Video-assisted thoracoscopic lobectomy for non-small cell lung cancer in patients with severe chronic obstructive pulmonary disease
Abstract
Objective: To assess the feasibility, safety and long-term outcomes of video-assisted thoracic surgery (VATS) lobectomy for the treatment of non-small cell lung cancer (NSCLC) in patients with severe chronic obstructive pulmonary disease (COPD).
Methods: The clinical data of patients with NSCLC and severe COPD (preoperative FEV1% <50%) who underwent VATS lobectomy from January 2000 to January 2011 were retrospectively analyzed to identify their demographic parameters, postoperative complications and outcomes.
Results: The preoperative FEV1/FVC was <70% and FEV1% <50% in all 61 patients in this study, with a mean preoperative FEV1 of 0.99 L (0.54-1.58 L) and mean FEV1% of 38.4% (22-49.82%). All of the 61 patients underwent the VATS lobectomy or sleeve resection plus systemic lymph node dissection. The mean operative time was 218 minutes (120-355 minutes), with a mean intraoperative blood loss of 342 mL (50-1,600 mL). None of the patients converted to thoracotomy. Multivariate statistical analysis revealed that age and TNM staging after tumor resection were independent predictive factors for the 5-year survival in those patients (P=0.014 and 0.013).
Conclusions: With preoperative imaging studies, pulmonary function assessment and target positioning, VATS lobectomy can be safely and effectively performed for patients with NSCLC and severe COPD to achieve a satisfying long-term survival outcome.
