Biliary tract cancer stem cells - translational options and challenges

Area of Science:

• Oncology
• Cancer Stem Cell Biology

Background:

• Biliary tract cancer (BTC) presents significant management challenges due to high recurrence rates and therapeutic resistance.
• The cancer stem cell (CSC) model posits that specific cell subpopulations drive tumor development, progression, and metastasis.
• CSCs are implicated in tumor aggressiveness, recurrence, and therapeutic resistance across various cancers.

Purpose of the Study:

• To review and discuss the role of CSCs in biliary tract cancer.
• To explore the connection between BTC tumorigenesis factors and CSCs.

Main Methods:

• Literature review of current research on CSCs in BTC.
• Analysis of studies investigating CSC markers in BTC models and tissues.
• Examination of the interplay between oncogenic signaling pathways, micro-RNAs, the tumor microenvironment, and CSCs in BTC.

Main Results:

• Evidence suggests the existence and clinical relevance of CSCs in biliary tract cancer.
• Established CSC markers show relevance in BTC models and tissues.
• CSCs are likely involved in BTC development, progression, aggressiveness, recurrence, and metastasis.

Conclusions:

• Cancer stem cells play a crucial role in biliary tract cancer.
• Understanding the CSC contribution to BTC is vital for developing novel therapeutic strategies.
• Targeting CSCs holds promise for overcoming therapeutic resistance and improving patient survival in BTC.
