title: Racial and socioeconomic status differences in survival of colorectal cancer patients in Hawaii.
abstract: The study reported here examines the survival experience up to 84 months of patients from the five major racial groups in Hawaii diagnosed with colorectal cancer during the years between 1960 and 1974 based on data in the Hawaii Tumor Registry. Previous research in Hawaii showed that racial differences in survival existed even after adjusting for sex, age at diagnosis, stage of the disease at diagnosis, and normal life expectancy. In this paper, socioeconomic status differences between racial groups are hypothesized as a possible explanation for these survival differences. The results show that socioeconomic status did account for some survival differences between racial groups beyond what could be explained by the other variables. After adjusting for all the covariates, the only statistically significant racial differences which remained were higher survival rates for the Japanese patients compared with the rates for the Hawaiian and Filipino patients. Socioeconomic status was not found, however, to have a statistically significant effect on survival independent of race or the other variables examined. Reasons for the modest effects of socioeconomic status in this study are discussed.
