Lung emphysema, particularly centrilobular emphysema (CLE), is linked to increased lung cancer risk. Severity of emphysema, age, and smoking history are key predictors for lung cancer occurrence in screening programs.
Area of Science:
- Pulmonary Medicine
- Radiology
- Oncology
Background:
- Lung cancer screening programs are crucial for early detection.
- Identifying high-risk individuals for lung cancer screening is essential.
- The relationship between lung emphysema and lung cancer risk requires further investigation.
Purpose of the Study:
- To determine the correlation between lung emphysema and lung cancer risk.
- To identify participants who would benefit most from lung cancer screening.
Main Methods:
- Cross-sectional study of 896 subjects from the MOLTEST-BIS lung cancer screening program.
- Low-dose computed tomography (LDCT) scans were visually and quantitatively evaluated for emphysema.
- Logistic regression analysis was used to identify significant predictors of lung cancer.
Main Results:
- Centrilobular emphysema (CLE) presence and severity correlated with age and smoking pack-years.
- Lung cancer occurrence was associated with pack-years, age, and the presence of CLE.
- Logistic regression identified pack-years, age, CLE severity, and emphysema clusters (Clas 1) as significant predictors.
Conclusions:
- Qualitative and quantitative emphysema assessments are correlated.
- Both the presence and severity of CLE are linked to a higher incidence of lung cancer.
- Emphysema severity, age, and smoking history are significant predictors of lung cancer occurrence.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
