OBJECTIVE: Racial and Ethnic disparities in access to surgical treatment, post-operative outcomes, and survival rates have been identified in cancer treatment. This study aims to identify differences in peri-operative outcomes between patients categorized by self-reported Ethnicity after robotic-assisted pulmonary lobectomy.
METHODS: We retrospectively analyzed 704 consecutive patients who underwent robotic-assisted pulmonary lobectomy by one surgeon at one institution over a 10.8-year period. Patients were grouped by Hispanic vs. Non-Hispanic Ethnicity from self-reported data within electronic medical records. Primary outcomes were skin-to-skin operative time, estimated blood loss (EBL), chest tube duration, hospital length of stay (LOS), and in-hospital mortality. Secondary outcomes included intra-operative and post-operative complications. Outcomes were analyzed by Wilcoxon Two-Sample Test, Kruskal-Wallis Test, Chi-Square Test, or Fisher’s Exact Test. RESULTS: Of 704 total patients, 599 patients had self-reported Ethnicity data available, with 563 Non-Hispanics and 36 Hispanics. There were no significant differences between Ethnicity groups for any of the primary or secondary peri-operative outcomes analyzed. There was no statistically significant difference in in-hospital mortality (p=1.000), but all 5 (0.8%) patients who died while in hospital were of Non-Hispanic Ethnicity. CONCLUSIONS: Following robotic-assisted pulmonary lobectomy, there were no statistically significant differences between patients of Hispanic and Non-Hispanic Ethnicity in skin-to-skin operative time, EBL, occurrence of intra-operative or post-operative complications, chest tube duration, hospital LOS, or in-hospital mortality. Robotic-assisted pulmonary lobectomy is feasible and safe, with no apparent disparity in outcomes based on Ethnicity.
