Microbiome & Cancer Working Group

An international initiative to deliver evidenced-based recommendations on the microbiome’s role in improving cancer patient outcomes

Our initiative responds to the urgent need of enabling clinicians to translate complex, cross-disciplinary microbiome science into practical cancer care, while guiding the next generation of research in this rapidly evolving field.

The microbiome is increasingly recognized as a central regulator of cancer pathophysiology and a critical determinant of cancer immunotherapy efficacy across both solid and hematologic malignancies.

This initiative seeks to address a pressing need: helping clinicians translate complex, cross-disciplinary science into practical care, while shaping the next wave of research in this rapidly evolving area.

We aim to evaluate how standard of care can better reflect current evidence on the microbiome's role in cancer treatment.

We aim to update the standard of care to reflect current evidence on how the microbiome influences cancer treatment.

Evaluate

Evidence on the role of the microbiome in cancer care, with a focus on microbiome-modifying agents and their impact on treatment outcomes.

Identify

Areas of consensus and key gaps in clinical evidence and practice knowledge, and standards for evidence generated from new research.

Author

Clinically actionable consensus recommendations for healthcare practitioners, a research agenda to address the most urgent next questions, and standards for preclinical, translational, and clinical evidence.

Advocate

Changes to clinical practice and new research efforts in line with the recommendations.
