Gut microbiome and colorectal adenomas.

Area of Science:

• Microbiology
• Gastroenterology
• Oncology

Background:

• The human gut harbors trillions of bacteria, forming the gut microbiome, crucial for host health.
• Gut microbiome dysbiosis, an imbalance in bacterial composition, is associated with various diseases.
• Colorectal cancer (CRC) is a major health concern, with adenomas as its precursors.

Purpose of the Study:

• To review recent insights into the gut microbiome's role in colorectal adenoma development and CRC progression.
• To highlight known risk factors for colorectal adenomas and potential mechanisms of microbial influence.
• To identify current knowledge gaps and future directions for CRC research.

Main Methods:

• Literature review of recent studies on the gut microbiota and colorectal adenomas/CRC.
• Analysis of potential mechanisms linking microbial dysbiosis to CRC etiology.
• Synthesis of current findings and identification of research gaps.

Main Results:

• Evidence suggests gut microbiome dysbiosis contributes to colorectal adenoma formation and CRC progression.
• Modulation of gut bacterial composition may be a strategy for preventing adenomas and CRC.
• Specific microbial contributions and mechanisms are still under investigation.

Conclusions:

• The gut microbiome plays a significant role in the development and progression of colorectal cancer.
• Further understanding of the microbiome offers potential for novel diagnostic tools, biomarkers, and therapeutics for CRC.
• Targeting the gut microbiome presents a promising avenue for CRC prevention and treatment.
