Incidence of Bronchopulmonary Carcinoma in Castile-Leon and Cantabria in 2007. Study from the Castile-Leon and Cantabria Respiratory Disease Society (SOCALPAR)

Abstract Introduction This study sets out to find out the incidence of bronchopulmonary cancer and other epidemiological characteristics in patients living in Cantabria and Castile-Leon (Spain), by comparing current data from the communities with that obtained 10 years ago in a similar study. Patients and methods Prospective, multicentre study using information (age, sex, residence, smoking habits and histology) obtained from all patients diagnosed during 2007. Results A total of 1,486 patients were included: 1,295 males (87.1%) and 191 females (12.9%). Of these, 1,145 lived in Castile-Leon: 1,010 males (88.2%) and 135 females (11.8%); while 341 lived in Cantabria: 285 males (83.6%) and 56 females (16.4%). The incidence rates per 100,000 inhabitants adjusted to the world standard population were significantly higher in Cantabria (29.53; [males: 52.9; females: 9.76]) than in Castile-Leon (21.35; [males: 38.31; females: 5.58]). A total of 90.24% were smokers (males: 96.12% and women: 49.17%). The main histology types were: squamous, 32.82%; adenocarcinoma, 28.74%; and small cell carcinomas, 18.33%. In Castile-Leon, from 1997 to 2007, the numbers went from 920 to 1,010 in males and from 95 to 135 in females (a crude increase rate of 10.5% in males and 43% in females), with a decrease in squamous tumours and an increase in adenocarcinomas. Conclusions The incidence rates of bronchopulmonary cancer in 2007 were significantly higher in Cantabria than in Castile-Leon. The 2007 rates in this community were higher than in 1997 for both males and females.
