Lung cancer: a new frontier for microbiome research and clinical translation.

Authors: Mur LA, Huws SA, Cameron SJ, Lewis PD, Lewis KE Abstract The lung microbiome has been shown to reflect a range of pulmonary diseases-for example: asthma, chronic obstructive pulmonary disease (COPD) and cystic fibrosis. Studies have now begun to show microbiological changes in the lung that correlate with lung cancer (LC) which could provide new insights into lung carcinogenesis and new biomarkers for disease screening. Clinical studies have suggested that infections with tuberculosis or pneumonia increased the risk of LC possibly through inflammatory or immunological changes. These have now been superseded by genomic-based microbiome sequencing studies based on bronchoalveolar lavage, sputum or saliva samples. Although some discrepancies exist, many have suggested changes...
