Research progress on the correlation between intestinal flora and colorectal cancer

Area of Science:

• Gastroenterology and Oncology
• Microbiome Research
• Genomics

Background:

• Colorectal cancer (CRC) is a leading cause of cancer mortality globally.
• Lifestyle and dietary changes are associated with increasing CRC incidence.
• The gut microbiome plays a critical role in CRC pathogenesis.

Purpose of the Study:

• To summarize the intricate relationship between the gut microbiome and colorectal cancer.
• To explore the potential of gut microbiota in CRC diagnosis and screening.
• To provide evidence for novel therapeutic strategies targeting the gut microbiome in CRC.

Main Methods:

• Review of current literature on gut microbiota and CRC.
• Analysis of next-generation sequencing and metagenomics data.
• Investigation of microbial biomarkers for CRC detection.

Main Results:

• Significant alterations in gut microbial composition are observed in CRC patients.
• Specific bacterial species and their metabolites are implicated in CRC development.
• Gut microbiome profiles show promise as non-invasive biomarkers for CRC screening.

Conclusions:

• The gut microbiome is a crucial factor in the development and progression of colorectal cancer.
• Targeting the gut microbiota offers potential for early CRC detection and personalized treatment.
• Further research into gut ecology is vital for advancing CRC management.
