Abstract:

Colorectal cancer (CRC) remains a substantial public health challenge globally and is the second leading cause of cancer-related death in the USA. Despite advances in screening and treatment, disparities in CRC outcomes persist, especially among Black individuals in the USA, who face higher CRC incidence and mortality and lower survival compared with White individuals. Inequities are largely attributed to social determinants of health (SDOH), such as access to health care, socioeconomic conditions and systemic inequities. In this Review, we examine Black-White disparities in CRC outcomes across the CRC care continuum in the USA, highlighting contributing modifiable (non-biological) and non-modifiable (biological) risk factors. We also discuss successful interventions that have reduced or eliminated disparities. Existing evidence suggests that Black-White differences in CRC screening participation, CRC incidence and CRC mortality can be resolved. Future efforts must emphasize improving access to screening and guideline-concordant treatment to achieve progress in the near term while addressing the underlying and historical SDOH that drive inequities to eliminate disparities in the long term. The Review underscores the need for sustained investment in addressing both immediate and systemic barriers to CRC screening and care in Black communities to eliminate disparities in CRC outcomes and improve the overall health of the nation.
