[Fecal Microbiota Transplantation: A Promising Avenue for Lung Cancer Therapy].

As lung cancer treatment continues to advance, mainstream approaches such as surgery, radiotherapy, chemotherapy, neoadjuvant therapy, targeted therapy and immunotherapy have become widely adopted in clinical practice. However, the efficacy of these methods is still limited and they are associated with significant side effects. In recent years, the pivotal role of the gut microbiota in tumor immune regulation has become increasingly recognized, with its potential impact on tumor immunotherapy emerging as a novel therapeutic focus in lung cancer management. Against this backdrop, fecal microbiota transplantation (FMT) has been proposed as a potential immunomodulatory strategy. It enhances host immune responses and improves the tumor immune microenvironment by regulating the gut microbiota. This paper provides a systematic review of the latest research advances in FMT for lung cancer treatment. Focusing on the relationship between gut microbiota and lung cancer, the therapeutic mechanisms of FMT and clinical application studies, it provides a comprehensive exploration of the challenges and prospects for the use of FMT in lung cancer therapy.
