Anatomic segmentectomy is increasingly being considered as a means of achieving an R0 resection for peripheral, small, stage I non-small-cell lung cancer. In the current study, we compare the results of video-assisted thoracic surgery (n = 104) versus open (n = 121) segmentectomy in the treatment of stage I non-small-cell lung cancer.
A total of 225 consecutive anatomic segmentectomies were performed for stage IA (n = 138) or IB (n = 87) non-small-cell lung cancer from 2002 to 2007. Primary outcome variables included hospital course, complications, mortality, recurrence, and survival. Statistical comparisons were performed utilizing the t test and Fisher exact test. The probability of overall and recurrence-free survival was estimated with the Kaplan-Meier method, with significance being estimated by the log-rank test.
Mean age (69.9 years) and gender distribution were similar between the video-assisted thoracic surgery and open groups. Average tumor size was 2.3 cm (2.1 cm video-assisted thoracic surgery; 2.4 cm open). Mean follow-up was 16.2 (video-assisted thoracic surgery) and 28.2 (open) months. There were 2 perioperative deaths (2/225; 0.9%), both in the open group. Video-assisted thoracic surgery segmentectomy was associated with decreased length of stay (5 vs 7 days, P < .001) and pulmonary complications (15.4% vs 29.8%, P = .012) compared with open segmentectomy. Overall mortality, complications, local and systemic recurrence, and survival were similar between video-assisted thoracic surgery and open segmentectomy groups.
Video-assisted thoracic surgery segmentectomy can be performed with acceptable morbidity, mortality, recurrence, and survival. The video-assisted thoracic surgery approach affords a shorter length of stay and fewer postoperative pulmonary complications compared with open techniques. The potential benefits and limitations of segmentectomy will need to be further evaluated by prospective, randomized trials.
解剖性肺段切除术越来越多地被视为实现外周型、小的Ⅰ期非小细胞肺癌R0切除的一种手段。在本研究中,我们比较了电视辅助胸腔镜手术(n = 104)与开放手术(n = 121)肺段切除术治疗Ⅰ期非小细胞肺癌的结果。
2002年至2007年,对138例IA期或87例IB期非小细胞肺癌连续进行了225例解剖性肺段切除术。主要结局变量包括住院过程、并发症、死亡率、复发率和生存率。采用t检验和Fisher精确检验进行统计学比较。采用Kaplan-Meier法估计总生存率和无复发生存率,通过对数秩检验评估显著性。
电视辅助胸腔镜手术组与开放手术组的平均年龄(69.9岁)和性别分布相似。平均肿瘤大小为2.3 cm(电视辅助胸腔镜手术组为2.1 cm;开放手术组为2.4 cm)。平均随访时间为电视辅助胸腔镜手术组16.2个月、开放手术组28.2个月。围手术期死亡2例(2/225;0.9%),均在开放手术组。与开放肺段切除术相比,电视辅助胸腔镜手术肺段切除术的住院时间缩短(5天对7天,P <.001),肺部并发症减少(15.4%对29.8%,P =.012)。电视辅助胸腔镜手术组与开放肺段切除术组的总死亡率、并发症、局部和全身复发率及生存率相似。
电视辅助胸腔镜手术肺段切除术在发病率、死亡率、复发率和生存率方面是可以接受的。与开放手术技术相比,电视辅助胸腔镜手术方法住院时间更短,术后肺部并发症更少。肺段切除术的潜在益处和局限性需要通过前瞻性随机试验进一步评估。
