Lung Microbiome in Lung Cancer: A New Horizon in Cancer Study

Area of Science:

• Oncology
• Microbiology
• Genomics

Background:

• Lung cancer is a major global health concern.
• The lung microbiome, comprising various microorganisms, is increasingly recognized for its role in health and disease.
• Previous assumptions of a sterile lung environment have been challenged by recent research.

Purpose of the Study:

• To review current knowledge on lung cancer-related microbiota.
• To explore the complex association between the lung microbiome and lung cancer.
• To discuss the lung microbiome's potential as a diagnostic and predictive biomarker.

Main Methods:

• Literature review of recent developments in lung cancer microbiota research.
• Analysis of studies investigating the link between microbiome dysbiosis and lung cancer.
• Examination of host-microbiome interactions in immune response regulation.

Main Results:

• Disruption of lung microbiome homeostasis correlates with increased lung cancer risk.
• Specific microbial compositions and their components are associated with lung cancer.
• The lung microbiome influences carcinogenesis through various mechanisms, including dysbiosis.

Conclusions:

• The lung microbiome plays a significant role in lung cancer initiation, progression, and metastasis.
• Understanding host-microbiome interactions is crucial for immune response modulation in lung cancer.
• The lung microbiome shows promise as a predictive and diagnostic biomarker for lung cancer.
