In California, colorectal cancer (CRC) is the second most common cancer in Latinos. Using data from the California Cancer Registry we investigated demographic and clinical characteristics of 36,133 Latinos with CRC living in California during 1995–2011 taking into account subpopulations defined by country of origin.
Cases were defined as Latino according to the North American Association of Central Cancer Registries Hispanic Identification Algorithm, which was also used to group cases by country of origin: Mexico (9,678, 27%), Central or South America (2,636, 7%), Cuban (558, 2%), Puerto Rico (295, 1%), and other or unknown origin (22,966, 64%; Other/NOS). 174,710 non-Hispanic white (NHW) CRC cases were included for comparison purposes. Annual age-adjusted incidence rates (AAIR) and proportional incidence ratios (PIRs) were calculated.
Differences were observed for age at diagnosis, sex distribution, socioeconomic status (SES), nativity (US- versus foreign-born), stage, and tumor localization across Latino subpopulations and compared to NHW. Mexican-Latinos had the lowest AAIR and Cuban Latinos had the highest. PIRs adjusted for age, SES, and nativity showed an excess of CRC males and female cases from Cuba, female cases from Puerto Rico and reduced number of female cases from Mexico.
Differences in cancer incidence patterns and tumor characteristics were observed among Latino subpopulations in California. These disparities may reflect differences in cancer determinants among Latinos; therefore, given that country of origin information is unavailable for a large proportion of these patients, greater efforts to collect these data are warranted.
