An epidemiologic study was carried out on 475 incident cases of gastric cancer registered by the Ragusa Cancer Registry (Sicily) between 1981 and 1988. Distribution by sex, age, subsite, year of incidence, and survival was investigated. A reduction of incidence and mortality between 1981–84 and 1985–88 was observed in both sexes, and was more evident in males than in females. Survival was not significantly different for cancers of the various subsites.
