🗞️   Faecal microbiota transplantation combined with platinum-based doublet chemotherapy and tislelizumab as first-line treatment for driver-gene negative advanced non-small cell lung cancer (NSCLC): study protocol for a prospective, multicentre, single-arm exploratory trial

Health

Introduction The standard first-line treatment for driver-gene negative advanced non-small cell lung cancer (NSCLC) is chemotherapy combined with immunotherapy. However, owing to the immune microenvironment imbalance and immune status impairment caused by repeated chemotherapy, as well as the primary or secondary resistance to immune checkpoint inhibitors, the efficacy of immunotherapy combined with chemotherapy remains unsatisfactory. Recent studies have shown that faecal microbiota transplantation (FMT) can modulate the intestinal microflora, influence the tumour immune microenvironment and even enhance the efficacy of immunotherapy. Hence, we conduct such a prospective, exploratory study to evaluate the efficacy and safety of integrating FMT with standard first-line treatment in patients with driver-gene negative advanced NSCLC.
