Cancer incidence among Filipinos in Los Angeles County, 1972-1991.

Although Filipinos are the second largest Asian subgroup in the United States, little is known about their patterns of cancer incidence. We have examined cancer incidence rates among Filipinos living in Los Angeles County from 1972 through 1991 and evaluated their risk of non-localized cancer relative to non-Hispanic whites. Although Filipinos have substantially lower cancer rates than non-Hispanic whites in Los Angeles County, their incidence rates of liver cancer, cancer of the nasopharynx and thyroid cancer are higher. Filipino men and women had somewhat more advanced cancer at diagnosis, on average, than non-Hispanic whites, though no statistically significant differences were observed for sites where early detection methods exist. Our data suggest that Filipino-Americans would benefit from increased screening for cervical and breast cancer as well as efforts to interrupt transmission of hepatitis B virus to reduce liver cancer incidence.
