Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The DEPRECAP (Early detection of lung cancer) study is an ongoing, prospective, longitudinal, multicenter lung cancer screening program that recruited individuals with COPD or emphysema from the pulmonary clinics of Fundación Jiménez Díaz University Hospital and Villalba General Hospital, in Madrid, Spain.

The aim of this observational study is to determine the scientific evidence needed to study the benefit and potential effects of lung cancer screening in this group of patients and to determine the long-term effects of the intervention in reducing the high mortality rates associated with late-stage lung cancer diagnosis in a very high-risk population, to address under-diagnosis of COPD and to promote smoking cessation. This leads to the creation of a registry with clinical, radiological, functional data and biological samples for future studies in this cohort of patients to provide the scientific evidence needed to study the benefit and potential effects of screening for lung cancer and other tobacco-related pathologies diagnosed by Low-dose CT (LDCT)

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participants who met the inclusion/exclusion criteria detailed below and agreed to participate, underwent annual LDCT and pulmonary function tests until age 75 or 15 years of smoking abstinence, whichever came first. The study protocol was approved by the Ethics Committee of the Fundación Jiménez Díaz (ER2\_EO180-19\_FJD-HGV) and all participants signed their informed consent.

Inclusion criteria were males or females, 55-75 years of age, current or former smokers (Less than 15 years of abstinence) with a cumulative smoking exposure of greather than 30 pack-years and a diagnosis of COPD according to the GOLD guidelines and/or emphysema identified by LDCT. Individuals with a recent history of cancer (except non-melanoma skin cancer or carcinoma in situ) as well as those with other medical conditions that posed a significant risk of death were excluded.
