Large Bowel Genetic Background and Inflammatory Processes in Carcinogenesis--Systematic Review

Area of Science:

• Oncology
• Molecular Biology
• Gastroenterology

Background:

• Colorectal cancer (CRC) is a leading cause of cancer death globally.
• CRC development is driven by genetic alterations and inflammation.
• Key genetic pathways include chromosomal instability (APC, K-RAS, DCC, p53) and the mutator pathway (KRAS, BRAF).

Discussion:

• Inflammation, particularly elevated pro-inflammatory cytokines, significantly impacts CRC.
• Colorectal polyps are critical risk factors and exhibit diverse carcinogenic pathways.
• Variations in COX-2 expression are observed across different adenomas.

Key Insights:

• CRC pathogenesis involves complex interactions between genetic mutations and inflammatory responses.
• Understanding the distinct molecular profiles of colorectal polyps is crucial.
• Targeted therapies may emerge from comprehending these parallel mechanisms.

Outlook:

• Further research into inflammatory processes and genetic alterations can refine CRC treatment strategies.
• Investigating the role of specific cytokines and COX-2 expression may lead to novel therapeutic targets.
• Personalized medicine approaches for CRC could be advanced by integrating genetic and inflammatory data.
