The effects of primary site, sex, age, stage and histological type on cancer patient survival were analysed on the basis of the population-based material of the Finnish Cancer Registry from 1985 to 1994.
In addition, trends in survival were constructed for the period 1955-1994.
Detailed site-specific data are published as Supplement 12 to Vol. 38 of Acta Oncologica.
Within a given site, the survival differences by gender were not large.
However, because of different site distributions, the average prognosis for female patients, all sites taken together, was superior to that of males : the 5-year relative survival rates (RSR) were 58% and 43%, respectively.
In general, older patients had a poorer outcome compared with younger patients (partly because of different stage and histology distributions).
Stage was a strong determinant of patient survival.
In some cancers with a poor average prognosis the 5-year RSR for localized tumours was reasonable, e.g. 61% for stomach cancer, males, 34% for gallbladder cancer, females, and 29% for lung cancer, males.
Most of the survival rates clearly increased over time.
In addition to improvements in cancer treatment, changes over time in several other factors affect the trends, such as changes in the stage distribution (early diagnosis as a result of health education, improved diagnostic methods, screening, etc.) and in the composition of the patient material because of changing definitions of cancer.
