Survival Analysis of Metastatic Young-Onset vs. Average-Onset Cholangiocarcinoma: A Population-Based Study

mYOCC demonstrates distinct metastatic patterns, including higher frequencies of bone and lung metastases, and is associated with better survival outcomes compared to mAOCC. These findings highlight the need for age-specific diagnostic and therapeutic approaches to improve outcomes for mYOCC patients. Further research is needed to understand the biological mechanisms underlying these differences and address disparities in survival outcomes.
