Retrospective cohort analysis reveals sex and racial disparities impact treatment timing in early-onset colorectal cancer.

To analyze how sex, race, and rurality affect treatment delays for early-onset colorectal cancer.
Retrospective cohort analysis of 79,090 EOCRC patients from 2006–2020
Utilized multiple imputation for missing data
Examined treatment initiation within 30, 60, and 90 days post-diagnosis
Applied Cox proportional hazards models adjusting for sociodemographic and clinical factors
Average time to treatment was 20 days, shortest in mostly rural areas
Male patients were 5% less likely to initiate treatment across all intervals
Hispanic and Asian/PI patients less likely to receive treatment within 90 days
Non-urban patients were 9%–12% more likely to receive timely treatment
88% initiated treatment within 30 days, but disparities persisted for minorities and urban residents.

Tsai et al. (2025) studied this question.
