RESUMO
PURPOSE: Disparities in colorectal cancer (CRC) trends are linked with socioeconomic status (SES) and race. To better understand the colon cancer trends at our medical center, this study characterizes the racial and socioeconomic profile of the population served by our center to identify modifiable risk factors amenable to interventions. METHODS: Colon cancer data from our center as well as New Jersey (NJ) and United States (US) were obtained from National Cancer Database. Demographic data on race and SES for NJ counties were obtained from public databases that sourced data from the American Community Survey and the US census. We compared the odds of being diagnosed with early-onset and late-stage colon cancer (III or IV), respectively in NJ and US, across different racial groups. We also quantified the association between Social Vulnerability Index (SVI) and age-adjusted CRC mortality in NJ counties, with and without accounting for the racial composition of each county. RESULTS: In 2015, our center recorded higher proportions of late-stage and early-onset colon cancer diagnoses compared to all hospitals in NJ and US. Trends for stage and patient age at diagnosis of colon cancer for NJ and the US (2010-2019) showed that Black, Hispanic, and Asian/Pacific Islander individuals had greater odds of being diagnosed with early-onset (age<50) and late-stage colon cancer (Stage III/IV) when compared to White population. NJ counties served by our center showed an overrepresentation of either Black or Hispanic-Latino populations and reported significant disadvantage in SES. For NJ counties, each 25 percentile increase in social vulnerability was associated with 1.04 times the rate of age-adjusted colorectal cancer death (95 % CI: 1.00-1.07). CONCLUSION: Public data on race and SES of the target population can help identify areas of social disparities at the county-level to guide targeted interventions such as improving healthcare access and screening rates.
