Fecal microbiota transplant to enhance immunotherapy in cancer patients: overview of the potential role of fecal microbiota transplant (FMT) as a therapeutic strategy to modulate the gut microbiome. Through FMT, donor microbiome is transferred to a recipient in the form of a stool suspension given either endoscopically or via pills. Key considerations in the design of FMT interventions include patient selection, donor profile, timing, FMT modality, and post-FMT follow-ups.
