Abstract:
FMT has gained enormous momentum in the treatment of acute inflammatory and infectious diseases. Despite an encouraging safety profile, FMT has been met with caution in the oncological setting due to perceived infectious risks in immunocompromised patients. Theoretical risks aside, the application of FMT in oncology may stand to benefit patients, via modulation of treatment efficacy and the mitigation of treatment complications. Here, we summarize most recent safety data of FMT in immunocompromised cohorts, including people with cancer, highlighting that FMT may actually provide protection against bacterial translocation via introduction of a diverse microbiome and restoration of epithelial defenses. We also discuss the emerging translational applications of FMT within supportive oncology, including the prevention and treatment of graft vs. host disease and sepsis, treatment of immunotherapy-induced colitis and restoration of the gut microbiome in survivors of childhood cancer.
Insights
Fecal microbiota transplantation (FMT) shows promise in cancer care, potentially protecting immunocompromised patients from infections and improving treatment outcomes. Emerging data suggest FMT can mitigate complications and support patients undergoing cancer therapy.
Area of Science:
- Gastroenterology and Hepatology
- Oncology
- Microbiome Research
Background:
- Fecal microbiota transplantation (FMT) is increasingly used for inflammatory and infectious diseases.
- Its application in oncology is cautious due to infection risks in immunocompromised patients.
Purpose of the Study:
- To review recent safety data of FMT in immunocompromised cancer patients.
- To explore FMT's potential benefits in supportive oncology.
Main Methods:
- Review of recent safety data.
- Discussion of translational applications in oncology.
Main Results:
- FMT may protect against bacterial translocation by diversifying the microbiome and restoring epithelial defenses.
- FMT shows potential in preventing/treating graft-vs-host disease, sepsis, and immunotherapy-induced colitis.
Conclusions:
- FMT appears safe and potentially beneficial in immunocompromised cancer patients.
- FMT has emerging roles in supportive oncology, including microbiome restoration.
