Stomach and colorectal cancers in Puerto Rican-born residents of New York City.
Colorectal cancer incidence and mortality rates for Puerto Rican-born residents in New York City (PR-NYC) for 1975-79 were about two times those for Puerto Ricans living in Puerto Rico (PR-PR) and one-half to almost two-thirds those for other whites in New York City. From 1958 to 1979, colon cancer mortality rates for PR-NYC increased dramatically (i.e., 212% in males and 54% in females), whereas in PR-PR, male rates increased only slightly and female rates remained constant. For stomach cancer, incidence rates for male and female PR-NYC were slightly, but not significantly, higher than those for male and female PR-PR. In contrast, stomach cancer mortality rates for PR-NYC were lower than those for PR-PR throughout the survey period, and mortality decreased substantially in all racial-ethnic groups in New York City and Puerto Rico from 1958 to 1979. Results of this study indicated that the changes in colorectal and stomach cancer incidence and mortality in Puerto Rican-born residents after migration to New York City, although not as dramatic as in migrants from Japan and Eastern Europe, were comparable to those observed for Hispanic migrants to New Mexico and Los Angeles.
