Gallbladder cancer epidemiology, pathogenesis and molecular genetics: Recent update

Area of Science:

• Gastroenterology and Hepatology
• Oncology
• Medical Genetics

Background:

• Gallbladder cancer is a rare biliary tract malignancy with significant geographical variations.
• It is often diagnosed late, leading to a poor prognosis and limited treatment options.
• The pathogenesis is poorly understood, with complex associations involving genetic and environmental factors.

Purpose of the Study:

• To provide a comprehensive and updated review of gallbladder cancer.
• To explore the interplay between epidemiology, molecular genetics, and pathogenesis.
• To offer insights into the undetermined pathophysiology of this orphan cancer.

Main Methods:

• Systematic literature review of published articles on gallbladder cancer.
• Searches conducted using PubMed and other online search engines.
• Inclusion of peer-reviewed articles published between 1982 and 2015.

Main Results:

• Gallbladder cancer incidence varies significantly across different geographical regions.
• Genetic and environmental factors play a crucial role in its development.
• Current understanding of pathogenesis remains incomplete, highlighting the need for further research.

Conclusions:

• Further research into the epidemiology, molecular genetics, and pathogenesis of gallbladder cancer is essential.
• A deeper understanding can lead to improved diagnostic strategies and therapeutic interventions.
• Addressing this rare cancer requires a multidisciplinary approach integrating genetic and environmental insights.
