Among a diverse underserved cohort of UC patients, racial/ethnic minority patients with UC, specifically Asians and Hispanics, had more severe disease at presentation compared to Caucasians. The differences may reflect disparities in timely access to specialty care and treatment and deserves greater attention and research.
Colorectal cancer (CRC) remains a leading cause of morbidity and mortality in the U.S. Disparities in access to care contribute to advanced CRC stage at diagnosis, and these disparities are most pronounced among underserved populations and ethnic minorities. We aim to evaluate race/ethnicity-specific disparities in CRC stage at diagnosis among an ethnically diverse, urban safety-net hospital. We retrospectively evaluated all adult CRC patients diagnosed from January 1, 2009 to October 1, 2015. CRC cases were confirmed by histopathology specimens from biopsies and/or surgical resection. CRC staging utilized American Joint Committee on Cancer (AJCC) staging systems and were stratified by race/ethnicity. Multivariate logistic regression models were utilized to evaluate disparities in AJCC stage at presentation (stage 3-4 vs. stage 0-2). Among 311 patients with CRC [51.5% male, 25.3% black, 18.7% Hispanic, 32.0% Asian, and mean age at diagnosis 58.1 years (SD 10.3)] 61.4% had advanced ACC stage 3-4 CRC at diagnosis. Among black patients with CRC, 73.3% had AJCC stage 3-4 cancer at time of diagnosis. On multivariate regression, blacks were nearly four times more likely to have advanced AJCC stage 3-4 CRC at diagnosis compared to whites (OR 3.70; 95% CI 0.97-14.11; p = 0.055). Among a diverse underserved population, over 60% of CRC were AJCC stage 3-4 at diagnosis, and nearly 75% of blacks with CRC had AJCC stage 3-4 at diagnosis. Advanced stage CRC at diagnosis limits options for potentially curative therapies, and increases the risk for cancer recurrence and mortality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
