[Research Progress on the Regulatory Mechanism of Respiratory Microbiota in the Comorbidity of Chronic Obstructive Pulmonary Disease and Lung Cancer].

Abstract

Both chronic obstructive pulmonary disease (COPD) and lung carcinoma (LC) are major public health challenges in China. With the continuous advancement of microbial detection methods, the role of the respiratory microbiome in the pathogenesis and progression of respiratory diseases has become increasingly prominent. This article systematically reviews the dynamic characteristics of the respiratory microbiome during the progression of COPD and LC, then explores its crucial bridging role in COPD-LC comorbidity through mechanisms such as persistently driving chronic inflammation, mediating genomic damage, and participating in immune regulation. The aim is to deepen the understanding of the respiratory microbiome, and to provide new perspectives for optimizing existing treatment strategies, exploring microbial biomarkers for early cancer screening, and improving the clinical management of chronic respiratory diseases.
