Abstract:
Objective:To compare and analyze the effects of total laparoscopic wedge resection and lobectomy in the treatment of stage ⅠA non-small cell lung cancer(NSCLC).Methods:A retrospective cohort study was used to collect 113 cases of stage IA NSCLC treated with total endoscopic surgery in Yantai Affiliated Hospital of Binzhou Medical University from January 2018 to January 2020. The clinical data of patients with NSCLC, including 69 males and 44 females. The age was (65.65±5.19) years old. According to the different surgical methods, they were divided into two groups: wedge resection group ( n=57) and lobectomy group ( n=56). The wedge resection group underwent total laparoscopic and the lobectomy group underwent total laparoscopic lobectomy. The operation related indexes(operation time, intraoperative blood loss, postoperative drainage time, postoperative drainage volume, number of lymph node dissection, first time to get out of bed after operation, first time to exhaust after operation, first time to defecation after operation and hospitalization time), lung function before and after operation [forced expiratory volume in the first second(FEV1), forced vital capacity(FVC), maximum expiratory flow(PEF), maximum ventilation volume (MVV)], complications and prognosis were collected between the two groups. The measurement data of normal distribution were expressed as mean ± standard deviation ( ± s). Independent t-test was used for comparison between groups, and paired sample t-test was used for comparison within groups. The chi-square test was used for comparison of enumeration data between groups. If there were two expected counts < 5, the continuous correction chi-square test was used. Multiple time points were compared using repeated measures one-way analysis of variance. Kaplan-Meier survival curve was used to analyze the survival of the two groups of patients, and Log-Rank test was used to test the survival difference. Results:The postoperative drainage time, postoperative drainage volume, the first time to get out of bed, the first exhaust time and hospitalization time in the pulmonary wedge resection group were(3.25±0.76) d, (218.77±15.93) mL, (18.86±3.51) h, (19.25±2.35) h, (9.23±1.65) d, and those in the lobectomy group were (5.09±1.21) d, (359.74±19.55) mL, (21.55±4.27) h, (22.02±2.85) h, (13.96±3.21) d. The difference between the two groups was statistically significant ( P<0.05). Both groups showed a decrease in FEV1, FVC, PEF and MVV volume at 3 months and 1 year after surgery, but the above indicators increased at 1 year after surgery compared to 3 months after surgery in the lobectomy group ( P<0.05). There was no statistical significant difference in FEV1, FVC, PEF and MVV between the two groups before and 1 year after surgery ( P>0.05). However, FEV1, FVC, PEF and MVV in the wedge resection group were higher than those in the lobectomy group at 3 months after operation ( P<0.05). After 3 years of follow-up, the recurrence-free survival rate and overall survival rate of the wedge resection group were 84.2%, 86.0%, and those of the lobectomy group were 98.2%, 98.2%. The difference between the two groups was statistically significant ( P<0.05). Conclusions:The safety of the two surgical methods for treating stage ⅠA NSCLC is comparable. Compared to patients undergoing lobectomy, lung wedge resection has a better short-term prognosis, reduces postoperative drainage, promotes postoperative recovery, and has a relatively small impact on short-term lung function. However, in terms of long-term prognosis, total laparoscopic lobectomy can achieve a relatively ideal survival prognosis.
