OBJECTIVES:We examined colorectal cancer (CRC) stage at presentation and mortality in a vulnerable population compared with nationally representative data.METHODS:CRC cases were identified from San Francisco General Hospital (SFGH) and the Surveillance Epidemiology and End Results (SEER) database.RESULTS:Fifty-five percent of the SFGH cohort presented with advanced disease, compared with 44% of the SEER cohort. Increased risk of advanced stage at presentation at SFGH compared with SEER was most evident among blacks and Asians. There was weak evidence for worse survival at SFGH compared with SEER overall. This varied by race with poorer survival at SFGH among whites and possibly blacks but some evidence for better survival among Asians. Among CRC patients at SFGH, Asians and Hispanics had better survival than whites and blacks. At SFGH, 44% had a diagnosis of CRC within 1 year of establishing care there. Of those who had established care at SFGH for at least 1 year, only 22% had exposure to CRC screening tests.CONCLUSIONS:These findings allow examination of CRC presentation by ethnicity in vulnerable populations and identify areas where access and utilization of CRC screening can be improved.
