Molecular pathogenesis of gallbladder cancer: An update

Area of Science:

• Gastroenterology
• Oncology
• Molecular Biology

Background:

• Gallbladder carcinoma (GBC) is a highly aggressive gastrointestinal malignancy with a poor prognosis.
• Its pathogenesis involves environmental, microbial, metabolic, and molecular factors, often initiated by chronic gallbladder inflammation.
• Genetic alterations play a significant role in GBC aggressiveness and patient outcomes.

Purpose of the Study:

• To review the current understanding of gallbladder carcinoma's molecular pathogenesis.
• To identify potential biomarkers for early diagnosis, therapy, and prognosis prediction.
• To explore future research directions for improved GBC management.

Main Methods:

• Literature review of molecular pathogenesis in gallbladder carcinoma.
• Analysis of genetic alterations and epigenetic modifications.
• Examination of targeted therapy agents and their clinical relevance.

Main Results:

• Chronic inflammation, gallstones, and microbial infections contribute to GBC carcinogenesis through genomic changes.
• Targeted therapies are being investigated for actionable mutations in EGFR, VEGF, mTOR, and other pathways.
• Epigenetic modifications, including micro-RNA dysregulation, are emerging as potential diagnostic and therapeutic targets.

Conclusions:

• Despite advancements in targeted therapies, patient survival for GBC remains poor.
• Further research into complex molecular pathways, including non-actionable genetic aberrations and epigenetic changes, is essential.
• Unraveling the intricate pathogenesis of GBC is critical for developing novel strategies for better patient management and improved survival rates.
