Incidence, survival and mortality in cervical cancer in Norway, 1956–1990

摘要: Abstract Long-term trends in incidence, survival and mortality were examined women with squamous cell carcinoma adenocarcinoma of the uterine cervix, diagnosed Norway 35-year period 1956–1990. During 1970s number cervical smears increased substantially Norway, although no organised screening programme was introduced. Special attention paid to time 1971–1990 evaluate effect extensive spontaneous screening. In addition, prognostic importance clinical stage age explored. patients incidence rate peaked 1971–1975, since when there has been a decrease. rose through years 1976–1990. Also, proportion adenocarcinomas this period. The rates both histological types declined modestly 1966–1990. A more favourable distribution noted among carcinomas (P = 0.00), but not adenocarcinomas, comparing two diagnostic periods 1971–1975 1981–1985. multivariate analysis (GLIM) revealed that most important factor 0.00). relative 0.04) last There tendency towards poorer prognosis younger group, did prove be an 0.08).
