Surviving rectal cancer: examination of racial disparities surrounding access to care.
Journal of Surgical Research 2017 May 2
BACKGROUND: The aim of this study was to evaluate whether survival differences are attributable to disproportionate access to stage-specific rectal cancer treatment recommended by the National Comprehensive Care Network.
METHODS: A retrospective analysis of the National Cancer Data Base between 1998 and 2006 was performed. A series of Kaplan-Meier survival analyses were used to compare 5-y survival among race cohorts. Propensity score matching was used to compare Caucasian and African American patients who received the same treatment by accounting for covariates.
RESULTS: 5-y overall survival in African Americans was 50.7% versus 56.2% in Caucasians (P < 0.001). In patients with stage I-III disease, 5-y survival was 58.7% in African Americans versus 63.1% in Caucasians (P < 0.001). Analysis of patients receiving surgery for stage I-III disease, revealed a 61.1% 5-y survival in African Americans versus 65.8% in Caucasians (P < 0.001). Propensity score matching did not eliminate the racial disparity. The median survival for Caucasian patients was 109.6 mo as compared to 85.8 mo for African Americans (P < 0.001).
CONCLUSIONS: These data show that access to standard care appears to decrease but not eliminate the survival differences between African Americans and Caucasians with rectal cancer.
