Introduction: Minimally invasive lung resection has been associated with improved outcomes; however, institutional characteristics associated with utilization are unclear. We hypothesized that the presence of surgical robots at institutions would be associated with increased utilization of minimally invasive techniques ., Methods: Patients with cT1/2N0M0 non-small cell lung cancer who underwent lung lobectomy between 2010 and 2020 in the National Cancer Database were identified. Patients were categorized by operative approach as minimally invasive surgery (MIS) versus open. Institutions were categorized as "high utilizers" of MIS technique if their proportion of MIS lobectomies was >50%. Multivariate logistic regressions were used to determine factors associated with proportion of procedures performed minimally invasively. Further multivariate models were used to evaluate the association of proportion of MIS procedures with 90-d mortality, hospital length of stay, and hospital readmission., Results: In multivariate analysis, passage of time by year (odds ratio [OR] 1.26; confidence interval [CI] 1.22-1.30) and presence of a robot at the facility (OR 3.48; CI 2.84-4.24) were associated with high MIS-utilizing facilities. High utilizers of MIS were associated with lower 90-d mortality (OR 0.89; CI 0.83-0.97) and hospital length of stay (coeff -0.88; CI -1.03 to -0.72). Hospital readmission was similar between high and low MIS-utilizing facilities (compared to low MIS-utilizing facilities: OR 1.06; CI 0.95-1.09)., Conclusions: Passage of time and the presence of surgical robots were independently associated with increased utilization of MIS lobectomy. In addition to being associated with improved patient-level outcomes, robotic surgery is correlated with a higher proportion of procedures being performed minimally invasively., (Copyright © 2024 Elsevier Inc.

Background: This study compares sublobar resections-wedge resection and segmentectomy-in clinical stage IA lung cancers. It tests the hypothesis that overall survival after wedge resection is similar to segmentectomy., Methods: Adults undergoing wedge resection or segmentectomy for clinical stage IA lung cancer were identified from The Society of Thoracic Surgeons General Thoracic Surgery Database. Eligible patients were linked to the Centers for Medicare and Medicaid Services database using a matching algorithm. The primary outcome was long-term overall survival. Propensity scores overlap weighting (PSOW) adjustment of wedge resection using validated covariates was used for group difference mitigation. Kaplan-Meier and Cox regression models analyzed survival. All-cause first readmission, and morbidity and mortality were examined using PSOW regression models., Results: Of 9756 patients, 6141 met inclusion criteria, comprising 2154 segmentectomies and 3987 wedge resections. PSOW reduced differences between the groups. Unadjusted perioperative mortality was comparable, but wedge resection showed lower major morbidity rates. Weighted regression analysis indicated reduced mortality and major morbidity risks in wedge resection. Kaplan-Meier analysis revealed no mortality difference between groups, which was confirmed by PSOW Cox regression models. The cumulative risk of readmission was also comparable for both groups, with Cox Fine-Gray models showing no difference in rehospitalization risks., Conclusions: In clinical stage IA lung cancer, relative to segmentectomy, wedge resection has comparable overall survival and lower perioperative morbidity, suggesting it is an equally effective option for the broader population of patients with clinical stage IA lung cancer, not only those at highest risk of complications., (Copyright © 2024 The Society of Thoracic Surgeons.
