Abstract
Survival of 1747 patients with cancer of the stomach, colon/rectum, lung and female breast was investigated on incident cases registered by the Ragusa Cancer Registry, covering the Province of Ragusa (275,000 inhabitants) between 1981 and 1986. Cases known from the death certificate only were excluded. Date of death was obtained by a linkage with death certificates issued for Ragusa residents. Living status was assessed directly at the Registrar's Office. Analysis was performed also by sex, age group and presence of histologic verification. Relative survival at 5 years of Ragusa cancer cases was of the same order of magnitude as that observed in the U.S.A. (1980) and in Switzerland (1970-1980). However, the slight differences observed were mostly in favor of the Swiss and American patients. Sex did not significantly influence survival, but younger patients survived longer than older ones. Lack of histologic verification was associated with poor survival.
