Despite the availability of effective early detection technologies, more than half (61%) of colorectal cancers in the United States and 55% in California are identified at an advanced stage. Data on colorectal cancer patients (N = 35,030) diagnosed from 2005 to 2007 were obtained from the California Cancer Registry. Multivariate analyses found a relationship among neighborhood concentration of recent immigrants, neighborhood rates of limited English proficiency, and late-stage colorectal cancer diagnosis. Hispanics living in neighborhoods with a greater percentage of recent immigrants (compared to the lowest percentage) had greater odds (OR 1.57, 95% CI 1.22, 2.02) of late-stage diagnosis whereas Hispanics living in neighborhoods with the highest percentage of limited English proficiency (compared to the lowest percentage) had lower odds (OR.71, 95% CI.51,.99) of late-stage diagnosis. These relationships were not observed for other ethnic groups. Results highlight the complex relationship among race/ethnicity, neighborhood characteristics, and colorectal cancer stage at diagnosis.
