    Abstract

    Survival is a key measure of the effectiveness of a healthcare system. European Latin countries have some similarities in their health systems; it is thus interesting to examine their differences in survival from cancer, here, lung cancer. The aim of the SUDCAN collaborative study was to compare the trends in the 1- and 5-year net survival from lung cancer and the trends in the excess mortality rates between six European Latin countries (Belgium, France, Italy, Portugal, Spain and Switzerland). The data were extracted from the EUROCARE-5 database. First, the net survival was studied over the 2000-2004 period using Pohar-Perme estimator. For trend analyses, the study period was specific to each country. The results are reported from 1992 to 2004 in France, Italy, Spain and Switzerland and from 2000 to 2004 in Belgium and Portugal. The analyses were carried out using a flexible excess rate modelling. Overall, the 1-year net survival from lung cancer ranged between 36 (Spain) and 43% (Belgium and Switzerland) and the 5-year net survival ranged between 11 (Spain) and 15% (Belgium and Switzerland). Between 1992 and 2004, the age-standardized survival increased considerably at 1 year, but increased less at 5 years after diagnosis. This increase was observed at ages 60 and 70, but was less obvious at age 80. There was little difference in net survival from lung cancer between European Latin countries, particularly in the more recent years. However, survival was slightly lower in Spain and Portugal than in France, Italy, Belgium and Switzerland. High-resolution studies with data on treatment, stage at diagnosis and comorbidities are needed to understand the reasons for these differences.
