[An analysis of survival data in the epidemiological context].
The present work reviews the methodology of survival analysis in the epidemiological field, especially within the framework of cancer registries. The main concepts used in survival analysis are presented, and the problems of competing mortality, as well as variable and stage adjustment are also discussed. Although the estimation and comparison of survival data distributions obtained from epidemiologic observations is technically possible nowadays thanks to a variety of statistical methods which take into account multiple proGnostic factors, it is proposed that pilot studies should be undertaken to look at the main problems related with potential selection biases and the standardization of prognostic factors to be evaluated.
