Synopsis of the course

This CME-accredited session explores the critical role of the gut microbiome in shaping response and resistance to immune checkpoint inhibitors in patients with solid tumors. It examines the impact of antibiotic use on treatment outcomes, highlighting the mechanisms underlying antibiotic-mediated resistance and the importance of antimicrobial stewardship in oncology care. The session also reviews emerging strategies to modulate the gut microbiome, including experimental approaches under investigation in clinical trials. Participants will gain insight into how microbiome-targeted interventions may enhance immunotherapy effectiveness and inform future clinical practice.
