Background: Spousal support has been associated with better outcomes in head and neck cancer patients. However, the effect of social support in lung cancer patients is unknown. This study investigated effects of marital status on perioperative outcomes following robotic-assisted video thoracoscopic (RAVT) pulmonary lobectomy. Methods: We retrospectively reviewed 707 consecutive patients who underwent RAVT pulmonary lobectomy by one surgeon over 10.8 years. One patient was excluded due to incomplete data. Patients were grouped as “married” (including married, civil union/domestic partner, or cohabitating/living together) or “unmarried” (including single, widowed, or divorced) based on marital status at time of surgery. Estimated blood loss (EBL), skin-to-skin operative time, chest tube duration, and hospital length of stay (LOS) were analyzed by Wilcoxon’s test. In-hospital mortality and conversion to open lobectomy were analyzed by Chi-Squared and Fisher’s tests. Significance was established at p≤0.05. Results: There were 470 “married” and 236 “unmarried” patients. There were more former smokers in the married group, while there were more current and nonsmokers in the unmarried group (p=0.015) (Table 1). There was no significant difference in chest tube duration (p=0.783) or hospital LOS (p=0.607). Unmarried patients experienced significantly fewer intraoperative complications (p=0.035) and in-hospital mortalities (p=0.036). Skin-to-skin operative time (p=0.2019), EBL (p=0.338), and conversion to thoracotomy (p=0.064) were not significantly different between groups. Conclusions: While unmarried patients demonstrated less risk of intraoperative complications and in-hospital mortality, lack of spousal support was not associated with greater EBL, skin-to-skin operative time, conversion to thoracotomy, chest tube duration, or hospital LOS.
