title: Stomach cancer in a native and migrant population in Puerto Rico and New York City, 1975 to 1979.
abstract: This study compares age-adjusted stomach cancer incidence and mortality rates, by sex, among Puerto Rican-born residents of New York City (NYC/PR) and Puerto Rico (PR/PR) for the time period 1975 through 1979. One, three, and five year observed survival for cases diagnosed between 1975 and 1977 were compared. The results indicate that age-adjusted stomach cancer incidence rates per 100,000 among NYC/PR males (58.94) and females (27.58) were slightly higher compared to rates among PR/PR males (54.48) and females (25.73), while age-adjusted mortality rates were substantially higher among PR/PR males (46.38 vs. 37.29) and females (22.76 vs. 17.84), although these differences were not statistically significant. Differentials in observed survival consistently favored NYC/PR after one (43% vs. 35%), three (20% vs. 14%), and five years (11% vs. 9%) of follow-up.
