Abstract Background:Analysis of trends in cancer survival in defined wellsurveilled populations can provide useful indications on advancements incancer management and treatment. Patients and methods:Survival rates from the Vaud Cancer Registrywere computed for 31,158 cases registered in 1984–1993, and comparedwith those registered in 1974–1978 and 1979–1983. Results:A systematic, albeit generally moderate, tendency towardsincreasing five-year relative survival was observed for both sexes and mostmajor cancer sites, including oral cavity and pharynx (0.38–0.43),stomach (0.21–0.26), colon (0.49–0.55), rectum (0.45–0.51),lung (0.08–0.12), skin melanoma (0.67–0.89), female breast(0.67–0.80), endometrium (0.72–0.84), ovary (0.28–0.37).prostate (0.44–0.66), testis (0.73–0.96), bladder(0.31–0.50), kidney and renal pelvis (0.41–0.59), thyroid(0.73–0.81), non-Hodgkin's lymphomas (0.37–0.63), Hodgkin'sdisease (0.61–0.81), and leukaemias (0.27–0.39). Survival for allcancers and both sexes combined, rose from 0.51–0.64 (0.57 for males,0.71 for females). No appreciable change in survival was observed for cancersof oesophagus, liver, gallbladder, pancreas, larynx, cervix uteri, brain,multiple myeloma, as well as unidentified or unknown origin neoplasms. Conclusions:Survival estimates for most cancer sites arecomparable to the US SEER dataset, and their pattern of trends are discussedin terms of improved diagnosis and treatment for various neoplasms.
