Lung and gut microbiota and their interaction with the carcinogenesis and development of lung cancer: a review / 生物工程学报

ABSTRACT

Lung microbiota and gut microbiota are closely related to lung cancer. Studies have shown that the dysbiosis, i.e., the significantly altered composition and structure of gut and lung microbiota, usually occurs in patients with lung cancer. With the introduction of "Gut-Lung Axis", an increasing attention has been paid to the close relationship between the lung and gut microbiota in human body. A deeper insight into this relationship would facilitate understanding the mechanisms behind the carcinogenesis and development of lung cancer. This article summarizes the composition of lung and gut microbiota in patients with lung cancer and the possible interaction mechanisms, highlighting the importance of the immune system in the Gut-Lung Axis. The effects of lung and gut microbiota on the clinical treatment of lung cancer were summarized, based on which the authors propose that the lung and gut microbiota can be used as novel targets for early diagnosis and treatment of lung cancer.
