Cholangiocarcinoma, a rare cancer, presents challenges due to varied subtypes and locations. This review addresses controversies in its epidemiology, treatment, and diagnosis for better understanding.
Area of Science:
- Hepatobiliary cancers
- Gastrointestinal oncology
- Biliary tract diseases
Background:
- Cholangiocarcinoma (CCA) comprises 10% of primary liver cancers and <3% of GI malignancies.
- CCA originates from biliary tract epithelium or hepatic progenitor cells.
- Classification includes intrahepatic, perihilar, and distal subtypes, complicating research.
Purpose of the Study:
- To provide a narrative review of key topics in cholangiocarcinoma.
- To highlight challenges in epidemiological studies and treatment management.
- To discuss controversies in liver transplantation, histology, and chemotherapy.
Main Methods:
- Narrative review of existing literature on cholangiocarcinoma.
- Analysis of epidemiological data and treatment outcomes.
- Discussion of diagnostic and therapeutic controversies.
Main Results:
- Significant geographical variations exist in cholangiocarcinoma incidence.
- Lack of subtype differentiation in studies hinders accurate outcome assessment.
- Controversies persist regarding optimal treatment strategies, including liver transplantation and chemotherapy.
Conclusions:
- Accurate classification and subtype-specific research are crucial for advancing cholangiocarcinoma understanding.
- Further research is needed to resolve controversies in management and treatment.
- This review synthesizes current knowledge on cholangiocarcinoma for clinicians and researchers.
