The authors compared the risk of dying from site‐specific cancer within five years after diagnosis for Hawaii residents diagnosed in 1960‐1964, 1965‐1969, and 1970‐1974. Twelve cancer sites were analyzed with adjustments for age at diagnosis and ethnicity by a multivariate method. Four of these sites were adjusted for sex as well. The adjusted relative risk for site‐specific cancer death was significantly greater than 1.0 (P < 0.05) when patients diagnosed in 1960‐1969 were compared with those diagnosed in 1970‐1974 for the following sites: stomach, rectum (males), lung, prostate, leukemia, and lymphoma. The adjusted relative risk was greater than 1.0, but not significantly greater, for the remaining cancer sites: colon, rectum (females), liver, pancreas, breast, corpus uteri, and ovary. These results indicate that, for several cancer sites, the risk of cancer death has significantly declined in Hawaii during 1960‐1974. However, specific reasons for this improvement in cancer prognosis were not determinable from the available data.
