Population survival studies are usually carried out within population-based cancer registries and are useful mainly for geographical and temporal survival comparisons. Survival studies based on clinical series of patients are traditionally executed to evaluate the efficacy of a given treatment or to analyze the prognostic role of clinical factors. Subjects from a case-control study on incidence of larynx and hypopharynx cancers in Turin, for the period 1979-82, were followed-up in order to study their survival. The analysis was based on 347 cases of larynx cancer (319 males and 28 females) and 48 cases of hypopharynx cancer (47 males and 1 female). For larynx cancer, observed five-years survival was 59% in males and 64% in females. Hypopharynx cancer had a worse prognosis (21%). In males suffering from larynx cancer, older age, extent of spread, birth in Northern Italy, and being unmarried proved to be statistically significant negative prognostic factors. The same variables were also predictive of survival for hypopharynx cancer. The one- and three-year relative survival for larynx cancer in Turin was higher than that reported by other cancer registries. For males, relative five-year survival figures range from 47% to 65%. Survival for hypopharynx cancer is considerably lower, five-year figures ranging from 13% to 35%. The survival study on lung cancer was based on all the incident cases recorded by the Lombardy Cancer Registry (L.C.R.) from 1976 to 1981; during this period there were 2042 cases of primary lung cancers occurred in males and 217 in females. Observed survival at one, three and five years from diagnosis was 29%, 8% and 5%, respectively. Survival decreased with increasing age; no important differences between sexes are evident. Information on tumor stage was available in 1904 cases and histotype was known in 1605. Three-year survival was 17% for localized tumors, 8% for tumors with regional metastasis, and 1% for tumours with distant metastasis. Epidermoid carcinomas had a better prognosis than non-epidermoid carcinomas in the first year of follow-up, survival being 38% and 29%, respectively; among non-epidermoid carcinomas the worst prognosis was for small-cell carcinomas. Comparisons between the LCR relative survival and that reported by other cancer registries did not show important differences, five-year figures ranging from 5% to 10% in males.(ABSTRACT TRUNCATED AT 400 WORDS)
