Such registry should demonstrate comparability with population-based data to ensure representativeness at population level. The aim is to compare the socio-demographic characteristics of the TTR with incidence data from the Red de Registros de Cáncer (REDECAN) and mortality data from the Instituto Nacional de Estadística (INE). Lung cancer data sources available to date, REDECAN and INE, were used. Lung cancer cases overall and disaggregated by sex and age groups were collected from each source of information and data were compared for the period 2017-2020. Sex and age group proportions of TTR were calculated for both databases (which collect incidence and mortality data), for the entire study period and broken down by year. A total of 17,109 incident lung cancer cases from the TTR, 58,668 estimated incident cases from REDECAN and 88,083 deaths registered from INE between 2017 and 2020 were included. In terms of sex, the proportions are very similar between the three sources and the differences do not exceed 4%. In terms of age, the differences are not large, being larger for mortality data in the older age group from the INE versus the TTR. The TTR seems to be representative of lung cancer cases diagnosed in Spain between 2019 and 2020, both by sex and age. This allows us to accurately characterise the status of this disease, which is the leading cause of cancer death in Spain, and that the analysis of results obtained from the RTT can be applied to cases of lung cancer diagnosed in our country.
