Safety and efficacy of video-assisted versus conventional lung resection for lung cancer

摘要

@@Objective:We sought to evaluate the use of videoassisted thoracoscopy among patients with lung cancer and its safety and effectiveness relative to conventional resection. Methods:A cohort study (1994-2002) was conducted by using the Surveillance,Epidemiology,and End-Results Medicare database.Video-assisted thoracoscopy and conventional resection were hypothesized to be equivalent in terms of risks of death.Equivalency was defined by a confidence interval of 0.72 to 1.28 for the odds of 30-day death and 0.89 to 1.11 for the hazard of death,corresponding to a difference of no more than 1 % for 30-day mortality and 5% for 5-year survival,respectively.
