Clinical outcomes and changes in lung function after segmentectomy versus lobectomy for lung cancer cases.

ABSTRACT: We compared the clinical outcomes and changes in pulmonary function test (PFT) results after segmentectomy or lobectomy for non-small cell lung cancer.The retrospective study included 212 patients who had undergone segmentectomy (group S) and 2336 patients who had undergone lobectomy (group L) from 1997 to 2012. The follow-up and medical record data were collected. We used all the longitudinal PFT data within 24 months postoperatively and performed linear mixed modeling. We analyzed the 5-year overall and disease-free survival in stage IA patients. We used propensity score case matching to minimize the bias due to imbalanced group comparisons.During the perioperative period, 1 death (0.4%) in group S and 7 (0.3%) in group L occurred. The hospital stay for the 2 groups was similar (median, 5.0 vs 5.0 days; range, 2-99 vs 2-58). The mean overall and disease-free survival period of those with T1a after segmentectomy or lobectomy seemed to be similar (4.2 vs 4.5 years, P=.06; and 4.1 vs 4.4 years, P=.07, respectively). Compared with segmentectomy, lobectomy yielded marginally significantly better overall (4.4 vs 3.9 years, P=.05) and disease-free (4.1 vs 3.6 years; P=.05) survival in those with T1b. We did not find a significantly different effect on the PFTs after segmentectomy or lobectomy.Both surgical types were safe. We would advocate lobectomy for patients with stage IA disease, especially those with T1b. A retrospective study with a large sample size and more detailed information should be conducted for PFT evaluation, with additional stratification by lobe and laterality.

Project description:BACKGROUND:The morbidity of lung cancer has long been the highest in cancer. Stage I, stage II and partly of stage III non-small cell lung cancer (NSCLC) are mainly treated by surgery. Lobectomy and segmentectomy both are common lung resection methods. Video-assisted thoracoscopic surgery (VATS) has been widely used in clinical, and the application of single-portvideo-assisted thoracoscopic surgery (SP VATS) has gradually been recognized and accepted by professors. With increasing degree of eldly in society, eldly patients already have become inceasingly difficulties in the diagnosis and treatment of NSCLC. The aim of this study is to explore and analyze clinical value of SP VATS lobectomy and segmentectomy in elderly patients with NSCLC. METHODS:In this retrospective observational study, the outcomes of 417 consecutive patients who had undergone SP VATS anatomic segmentectomy or lobectomy for NSCLC from May 2014 to December 2016 on department of thoracic surgery in Fujian Medical University Affiliated Union Hospital were examined, including 139 elderly-case (lobectomy vs segmentectomy: 124 vs 15) and 278 nonelderly-case (lobectomy vs segmentectomy: 248 vs 30). The condition of perioperative period and postoperative short-time recovery could be compared with lobectomy and segmentectomy between elderly and nonelderly cases and lobectomy and segmentectomy in elderly cases. RESULTS:The morbidty of preoperative complications was significant difference (P<0.05) in comparing with elderly and non-elderly patients with NSCLC either in SP VATS anatomic segmentectomy orlobectomy, except others is no significant difference (P>0.05). Numbers of dissected lymph nodes and mediastinal nodal stations of SP VATS lobectomy in elderly patients with NSCLC were more than segmentectomy (P<0.05), which were (7.61±0.21) vs (20.39±0.97) and (5.60±0.35) vs (15.40±2.64). But there was not significant difference between two elderly groups of SP VATS lobectomy and anatomic segmentectomy in age, morbidty of preoperative complications, average operation time and intraoperative blood loss (P>0.05). Postoperative drainage volume [(1,150.15±140.02) mL vs (853.53±177.04) mL] and duration [(7.00±1.31) d vs (5.00±0.74) d], duration of postoperative hospital stay [(3.18±1.32) d vs (5.04±1.30) d], costs [(70.06±5.23) thousands yuan vs (61.20±5.22) thousands yuan ] or postoperative complications (5.97% vs 20.00%)(P>0.05). Notwithstanding, group of SP VATS anatomic segmentectomy found more postoperative atrialfibrillation and the vein thrombosis of lower limbs (P<0.05). CONCLUSIONS:Elderly patients having more basic diseases and taking increasely risk of postoperative complications. SP VATS anatomic segmentectomy andlobectomy do not increase the risk of elderly patients with surgery. SP VATS segmentectomy is as safe and effective as SP VATS lobectomy in elderly patients, who fit to undergo SP VATS segmentectomy seem to get as same short-time effect as SP VATS lobectomy.

Project description:BackgroundLobectomy has long been regarded as the standard treatment for operable non-small cell lung cancer (NSCLC). Recent studies suggested that segmentectomy could achieve a good prognosis for early-stage NSCLC and might be an alternative to lobectomy in this cohort. Until now, on the issue of comparison between lobectomy and segmentectomy, there remains no published randomized controlled trial (RCT), and all existing evidence is low. Recently, a categorization of lower-level evidence has been proposed, namely, the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. The aim of this meta-analysis is to compare the oncologic outcome between lobectomy and segmentectomy in NSCLC with the clinical T1N0M0 stage according to the GRADE system.MethodsPubMed, the PMC database, EMBASE, Web of Science, and the Cochrane library were searched prior to May 2019 to identify studies that compared the prognosis between lobectomy and segmentectomy for clinical T1N0M0 NSCLC. The evidence level of the included studies was assessed according to the GRADE system, including level IIA, probably not confounded nonrandomized comparison; level IIB, possibly confounded nonrandomized comparison; and level IIC, probably confounded nonrandomized comparison. The predefined outcomes included overall survival (OS) and disease-free survival (DFS). Univariable and multivariable hazard ratios (HRs) with 95% confidence intervals (95% CI) were pooled using a random-effects model.ResultsTwelve nonrandomized studies involving 8,072 participants were included. Of these studies, two were classified as IIA level (16.7%), six as IIB level (50.0%), and four as IIC level (33.3%). When crude HRs were included, compared with lobectomy, segmentectomy was associated with shorter OS but comparable DFS in the entire cohort (OS, pooled HR =1.45, 95% CI, 1.23 to 1.67; DFS, pooled HR =1.03, 95% CI, 0.65 to 1.82) and in patients with nodules ?2 cm (OS, pooled HR =1.55, 95% CI, 1.33 to 1.80; DFS, pooled HR =0.98, 95% CI, 0.55 to 1.77). When adjusted HRs were included, the impact of segmentectomy on OS and DFS was comparable to that of lobectomy in the entire cohort (OS, pooled HR =1.39, 95% CI, 0.92 to 2.10; DFS, pooled HR =0.83, 95% CI, 0.66 to 1.03) and in patients with nodules ?2 cm (OS, pooled HR =1.61, 95% CI, 0.87 to 3.00; DFS, pooled HR =0.90, 95% CI, 0.63 to 1.27).ConclusionsBased on our results, although shorter OS is observed in patients received segmentectomy, it is necessary to wait for more results from RCT to draw a valid conclusion.

Project description:ObjectivesThe aim of this study is to compare the postoperative complications, perioperative course, and survival among patients from the multicentric Spanish Video-assisted Thoracic Surgery Group database who received video-assisted thoracic surgery lobectomy or video-assisted thoracic surgery anatomic segmentectomy.MethodsFrom December 2016 to March 2018, a total of 2250 patients were collected from 33 centers. Overall analysis (video-assisted thoracic surgery lobectomy = 2070; video-assisted thoracic surgery anatomic segmentectomy = 180) and propensity score-matched adjusted analysis (video-assisted thoracic surgery lobectomy = 97; video-assisted thoracic surgery anatomic segmentectomy = 97) were performed to compare postoperative results. Kaplan-Meier and competing risks method were used to compare survival.ResultsIn the overall analysis, video-assisted thoracic surgery anatomic segmentectomy showed a lower incidence of respiratory complications (relative risk, 0.56; confidence interval, 0.37-0.83; P = .002), lower postoperative prolonged air leak (relative risk, 0.42; 95% confidence interval, 0.23-0.78; P = .003), and shorter median postoperative stay (4.8 vs 6.2 days; P = .004) than video-assisted thoracic surgery lobectomy. After propensity score-matched analysis, prolonged air leak remained significantly lower in video-assisted thoracic surgery anatomic segmentectomy (relative risk, 0.33; 95% confidence interval, 0.12-0.89; P = .02). Kaplan-Meier and competing risk curves showed no differences during the 3-year follow-up (median follow-up in months: 24.4; interquartile range, 20.8-28.3) in terms of overall survival (hazard ratio, 0.73; 95% confidence interval, 0.45-1.7; P = .2), tumor progression-related mortality (subdistribution hazard ratio, 0.41; 95% confidence interval, 0.11-1.57; P = .2), and disease-free survival (subdistribution hazard ratio, 0.73; 95% confidence interval, 0.35-1.51; P = .4) between groups.ConclusionsVideo-assisted thoracic surgery segmentectomy showed results similar to lobectomy in terms of postoperative outcomes and midterm survival. In addition, a lower incidence of prolonged air leak was found in patients who underwent video-assisted thoracic surgery anatomic segmentectomy.
