Does Race or Ethnicity Impact Complications After Pulmonary Lobectomy for Patients With Lung Cancer?

Background: Racial disparity in surgical access and postoperative outcomes after pulmonary lobectomy continues to be a concern and target for improvement; however, evidence of independent impact of race on complications is lacking. The objective of this study was to investigate the impact of race/ethnicity on surgical outcomes after lobectomy for lung cancer and estimate the distribution of racial/ethnic groups among expected resectable lung cancer cases using a large national database. Methods: Patients who underwent lobectomy for lung cancer between 2005 and 2016 were identified in the American College of Surgeon National Surgical Quality Improvement Program. Preoperative characteristics and postoperative outcomes were compared be-tween race/ethnicity groups in all patients and in propensity-matched cohorts, controlling for pertinent risk factors. Distribution of each race/ethnicity in the database was calculated relative to estimated numbers of patients with resectable lung cancer in the United States. Results: A total of 10,202 patients (age 67.6 +/- 9.7, 46.7% male, 86.4% white) underwent nonemergent lobectomy (46.8% thoracoscopic). Blacks had higher rates of baseline risk factors. In propensity score-matched cohorts of whites, blacks, andHispanics/Asians (n = 498 each), postoperatively, blacks had higher rates of prolonged intubation and longer hospital stay while whites had a higher rate of pneumonia. Race was independently associated with these adverse outcomes on multivariate analysis. Proportion of blacks and Hispanics in the American College of Surgeon National Surgical Quality Improvement Program was lower than their respective proportion of resectable lung cancer in the United States. Conclusions: In a large national-level surgical database, there was lower than expected representation of black and Hispanic patients. Black race was independently associated with extended length of stay and prolonged intubation, whereas white was independently associated with postoperative pneumonia. (C) 2021 Elsevier Inc.
