Microbiome, inflammation and colorectal cancer

Area of Science:

• Gastroenterology
• Oncology
• Microbiology

Background:

• Chronic inflammation is a known driver of various cancers, including colorectal cancer.
• Tumor-infiltrating immune cells contribute to cancer progression through inflammation.
• The gut microbiome's role in colorectal cancer is increasingly recognized.

Purpose of the Study:

• To review the intricate relationship between gut microbiota, inflammation, and colorectal cancer.
• To elucidate the mechanisms by which the gut microbiome and inflammatory cytokines influence colorectal tumorigenesis.

Main Methods:

• Literature review of studies on microbiota, inflammation, and colorectal cancer.
• Analysis of mechanisms involving bacterial interactions, immune cells, and cytokines in colorectal cancer development.

Main Results:

• Gut inflammation promotes cancer-causing mutations and tumor initiation.
• Bacteria can drive colorectal cancer by breaching barriers, causing inflammation, and generating genotoxicity.
• A balanced microbiome can prevent colorectal cancer by producing beneficial metabolites and reducing inflammation.

Conclusions:

• The gut microbiome and inflammation are critical regulators of colorectal cancer.
• Further research into these mechanisms can lead to novel therapeutic strategies for colorectal cancer.
