Selection criteria, methods of analysis and results presentation issues.
In this paper we presented materials and methods used for analysing survival of cancer patients recorded by the Italian cancer registries. First, we included first primary malignant tumours and excluded skin carcinomas, and cases identified by death certificate only, or by autopsy. Observed survival has been computed with the life-table method, with one month time lags. We corrected survival rates by the overall mortality effect (relative survival) with the Hakulinen method. The relative survival was age and sex adjusted with the EUROCARE method. Finally we discussed the results presentation issues.
