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.
对1747例胃癌、结肠癌/直肠癌、肺癌和女性乳腺癌患者的生存情况进行了调查，这些病例来自拉古萨癌症登记处登记的新发病例，涵盖1981年至1986年期间的拉古萨省（27.5万居民）。仅从死亡证明得知的病例被排除。通过与为拉古萨居民开具的死亡证明进行关联来获取死亡日期。在登记员办公室直接评估存活状态。还按性别、年龄组和组织学验证情况进行了分析。拉古萨癌症病例的5年相对生存率与美国（1980年）和瑞士（1970 - 1980年）观察到的生存率处于同一数量级。然而，观察到的细微差异大多有利于瑞士和美国患者。性别对生存没有显著影响，但年轻患者比老年患者存活时间更长。缺乏组织学验证与生存率低相关。
