RESUMEN
Background: This study investigates the evolution of lung cancer in the population of Burgos over more than a decade, focusing on key variables such as age, gender, histology, and stage of diagnosis. The aim is to understand how incidence rates and patterns have changed over time, especially in terms of early diagnosis. Methods: Retrospective data were collected from the Burgos University Hospital using histological or clinicoradiological methods. This data collection approach enabled a comprehensive examination of lung cancer trends in the province. Results: The results reveal an overall decrease in lung cancer incidence rates in men, offset by a steady increase in women. Histological analysis highlights a significant increase in adenocarcinoma, accounting for 43% of cases in the last year studied. Despite diagnostic advances, almost half of the diagnoses were made at stage IV, with no statistically significant change from previous years, highlighting persistent challenges in early diagnosis. Conclusions: The findings will not only inform resource management and prevention but could also have a significant impact on improved screening strategies and future lung cancer research.
