Abstract
OBJECTIVE: The number of octogenarians who present with localized lung cancer eligible for surgical resection is increasing. Video-assisted thoracic surgery lobectomy has been widely accepted, but the potential benefit in octogenarians is not well established, especially for postoperative mortality. This study aimed to assess the impact of a video-assisted thoracic surgery approach on postoperative mortality after lobectomy for lung cancer in octogenarians. METHODS: From January 2005 to December 2016, all patients aged more than 80 years who received lobectomy treatment for lung cancer were retrieved from the French Administrative Database. The end point was 30-day postoperative death. A propensity score was generated with 16 pretreatment variables and used to create balanced groups with matching (578 matches 1:1). Results are reported as odds ratios and 95% confidence intervals. RESULTS: Of the 75,892 patients operated for lobectomy during this period, 3560 were octogenarians. Video-assisted thoracic surgery was performed in 16.7% (n = 597) of cases, and thoracotomy was performed in 83.23% (n = 2963) of cases. From 2005 to 2016, the number of patients aged more than 80 years who were operated for lung cancer increased from 160 to 456 patients per year, and the proportion of lobectomy performed by video-assisted thoracic surgery increased as well (from 3.13% to 37.28%). Unmatched postoperative mortality was 3.85% (n = 23) for video-assisted thoracic surgery versus 7.9% (n = 234) for thoracotomy (P < .0001). Matched postoperative mortality was significantly lower in the video-assisted thoracic surgery approach with an odds ratio of 0.51 (95% confidence interval, 0.27-0.96; P = .038). CONCLUSIONS: Video-assisted thoracic surgery was significantly associated with reduced postoperative mortality compared with open thoracotomy after lobectomy for lung cancer in octogenarians.
