IMPORTANCE Colorectal Cancer (CRC) disparities continue to mostly impact vulnerable populations. Across the CRC continuum, most focus has been attributed to interventions in prevention, detection, and diagnosis. Varying surgical outcomes has emerged as an important contributing factor to CRC disparities.
OBJECTIVE To evaluate the distribution of publications across the CRC care continuum, examine interventional studies related to CRC Surgery, and synthesize findings in studies evaluating CRC disparities in Surgery.
DATA SOURCES We searched PubMed for prospective or retrospective studies reporting data on colorectal cancer disparities.
STUDY SELECTION Studies were selected if: (1) articles used US-sourced data (2) articles were published in the English language (3) Subjects included humans only or data.
MAIN OUTCOMES AND MEASURES Odds ratios for receipt of surgery for black vs. white patients were pooled from studies that performed multivariate analysis. Subgroup analysis was performed per procedure type.
RESULTS No publications regarding interventions associated with improvements in colorectal cancer surgery were found. Of the 1600 articles identified, an analysis was conducted from 18 publications. It included 89,214 black patients and 646,990 white patients. Black patients were significantly less likely to receive surgical treatment for CRC than white patients. This was confirmed in the sensitivity analysis by cancer site (colon vs rectum).
CONCLUSIONS AND RELEVANCE Based on the results, the majority of studies on CRC disparities have focused on access to prevention, diagnosis and screening. Considering the impact of varying surgical outcomes on vulnerable populations, it should be considered to shift research focus from process-oriented interventions to outcomes.
