Summary
Cholangiocarcinomas are diverse biliary tract cancers. Accurate classification, considering molecular and anatomical differences, is crucial for developing targeted therapies.
Area of Science:
- Gastroenterology
- Oncology
- Pathology
Background:
- Cholangiocarcinoma encompasses diverse malignant epithelial neoplasms.
- These tumors exhibit varied morphology, etiology, and pathogenesis.
Purpose of the Study:
- To review the etiology, pathogenesis, diagnostic criteria, classification, and molecular alterations of intra- and extrahepatic cholangiocarcinomas.
- To highlight the importance of precise classification for targeted therapy development.
Main Methods:
- Comprehensive literature review.
- Synthesis of current knowledge and personal expertise.
Main Results:
- Cholangiocarcinomas are morphologically and molecularly diverse, arising throughout the biliary tract.
- Distinct molecular differences exist between intrahepatic (iCCA) and extrahepatic (eCCA) subtypes.
- Precursor lesions with etiological links have been identified.
Conclusions:
- Exact classification of cholangiocarcinomas is essential due to histological overlap and frequent liver metastases.
- Subclassification into iCCA, perihilar (pCCA), and distal (dCCA) is based on macro-anatomical criteria.
- Understanding these diverse neoplasms is critical for advancing innovative, targeted therapeutic strategies.

Tumor Progression
7.1K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Mutagenicity and Carcinogenicity
1.7K
Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...

Cancer
53.1K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
