Abstract: Global survival studies in cancer have generally shown favourable development, but studies over extended periods on populations for which medical care is essentially free of charge are lacking.We analyse relative 1- and 5-year survival in all solid cancers in Denmark, Finland, Norway and Sweden through a 50-year period (1970-2019) using the NORDCAN database.The most recent survival results showed three types of patterns. Cancers of very good survival (5-year survival ∼90%) included common cancers of the breast and prostate, as well as melanoma. The second pattern, which included the largest number of cancers, showed 1-year survival of over 80% and a drop of 10-20 % units in 5-year survival. The third group consisted of eight fatal cancers, sharing poor 5-year survival (around 20%). The 50-year improvement in 1-year survival was largest (30-50 % units) in kidney, brain, gallbladder and liver cancers, and (∼30%) in colon, small intestinal, lung, pleural, pancreas and ovarian cancers. Improvements in 5-year survival were highest (40-50 % units) in prostate and kidney cancers but remained at 10-20 % units for the eight fatal cancers. Survival showed significant sex preferences for a few cancers.The analysis over a half-century confirms the progress in 'real-world' cancer control, and in 84% of patients 5-year survival was >60%. Metastases remain a challenge, placing the emphasis on early detection before metastasis occurs. Novel therapies, such as immunotherapy which has curative potential even against metastatic disease, are needed.
