Marital status shows no protective effect on perioperative outcomes after robotic-assisted pulmonary lobectomy.

Background: Marital status has been shown to have protective effects for married patients with various cancers. We sought to determine effects of marital status on perioperative outcomes after robotic-assisted pulmonary lobectomy (RAPL).

Methods: We retrospectively analyzed 709 consecutive patients who underwent RAPL between 2010 and 2022 by one surgeon. Patients were stratified by marital status at time of surgery. The Married group included married, domestically partnered, and co-habitating patients ( = 473). The Unmarried group included never married, divorced, and widowed individuals ( = 236). Demographics, preoperative comorbidities, intraoperative and postoperative complications, estimated blood loss (EBL), chest tube duration, hospital length of stay (LOS), tumor characteristics, and survival data were analyzed utilizing Student's -test, Wilcoxon rank-sum test, Chi-square, or Fisher's exact test as appropriate, with significance at

Results: Unmarried patients were more likely to be female, while married patients were more likely to experience robotic-associated intraoperative complications and greater intraoperative estimated blood loss. Kaplan-Meier survival analysis revealed no difference in 5-year overall survival based on marital status. Other perioperative outcomes, intraoperative complications (except robotic-associated), postoperative complications, demographic history (except gender), and preoperative comorbidities did not significantly differ between the two groups.

Conclusion: This study challenges the existing reports in the literature that marriage confers cancer treatment outcomes advantage and prolonged survival among cancer patients. Social support, in terms of a spouse or domestic partner, may be less protective in early-stage lung cancer and after minimally invasive pulmonary lobectomy compared to other cancer populations.
