GOALS: To investigate trends in colorectal cancer (CRC) incidence and survival among Hispanics in Texas. BACKGROUND: The incidence of CRC is rising among young adults in the United States. Given Texas' large Hispanic population, investigating CRC trends in Texas may provide valuable insight into the future of CRC epidemiology in an ever-diversifying US population. STUDY: Data from the Texas Cancer Registry (1995 to 2010) were used to calculate age-adjusted CRC rates based on the 2000 US standard population. Annual percentage change (APC) and 5-year cancer-specific survival (CSS) rates were reported by age, race/ethnicity, stage, and anatomic location. RESULTS: Of 123,083 CRC cases, 11% occurred in individuals below 50 years old, 26% of whom were Hispanic. Incidence was highest among African Americans (AAs; 76.3/100,000), followed by non-Hispanic whites (NHWs; 60.2/100,000) and Hispanics (50.8/100,000). Although overall CRC incidence declined between 1995 and 2010 (APC, -1.8%; P<0.01), trends differed by age and race/ethnicity. Among individuals 50 years and above, the rate of decline was statistically significant among NHWs (APC, -2.4%; P<0.01) and AAs (APC, -1.3%; P<0.01) but not among Hispanics (APC, -0.6%; P=0.13). In persons aged 20 to 39 years, CRC incidence rose significantly among Hispanics (APC, 2.6%; P<0.01) and NHWs (APC, 2.4%; P<0.01), but not AAs (APC, 0.3%; P=0.75). CSS rates among Hispanics and NHWs were comparable across most age groups and cancer stages, whereas CSS rates among AAs were generally inferior to those observed among NHWs and Hispanics. CONCLUSIONS: Although CRC incidence has declined in Texas, it is rising among young Hispanics and NHWs while declining more slowly among older Hispanics than among older NHWs and AAs.
