Objective

To describe the burden of colorectal cancer (CRC) in Mexico and understand mortality patterns based on sex, geography, and insurance status.

Materials and methods

Mortality data (1998-2018) from the Instituto Nacional de Estadística y Geografía was obtained. We included colon (C18.0, C18.2-18.9) and rectal cancer ICD-10 codes (C19, C20), and estimated age-standardized national, state-level and health insurance mortality rates. We estimated the average annual percent change using joinpoint regression.

Results

Between 1998 and 2018, the observed women and men mortality rate increased annually by 1.3 and 2.7%, respectively. Higher CRC mortality was observed in northern and more urbanized states and in groups with greater access to health insurance, which currently facilitates but does not routinely cover screening.

Conclusion

CRC mortality in Mexico is increasing rapidly, with marked differences based on sex, geography, and insurance status. Our findings underscore potential benefits of increased investment in comprehensive screening, diagnosis, and treatment strategies for the general population.
