The Cancer Microbiome: Recent Highlights and Knowledge Gaps.

Area of Science:

• Microbiome research
• Cancer biology
• Translational oncology

Background:

• The human microbiome is increasingly recognized as a critical factor in cancer initiation, progression, and prognosis.
• Expanding knowledge reveals specific microbial species and community structures associated with cancer development.

Purpose of the Study:

• To review recent investigations on microbial species linked to cancer.
• To highlight gastrointestinal and non-gastrointestinal cancers with strong bacterial associations.
• To guide future research on microbiota's role in cancer formation.

Main Methods:

• Literature review of recent scientific investigations.
• Focus on studies with well-defined experimental and translational evidence.
• Analysis of microbiome composition and structure in relation to cancer.

Main Results:

• Emerging data strongly support the microbiome's contribution to cancer biology.
• Specific bacterial associations are identified in various cancer types.
• Multifaceted mechanisms linking microbiota to cancer are being elucidated.

Conclusions:

• The microbiome significantly impacts cancer development and progression.
• Targeting microbiome alterations presents novel therapeutic avenues.
• Further research is crucial for understanding and exploiting these connections for improved patient outcomes.
