The heterogeneity of iCCA poses significant challenges to both targeted therapy and immunotherapy, necessitating in-depth exploration at the molecular and subtyping levels.

Stratifying iCCA patients allows for more precise treatment selection, ultimately improving survival outcomes.

Variceal EPS arise from originally small vessels with pre-existing dual portal and systemic drainage. Due to elevated portal pressure, these vessels dilate and undergo a reversal of flow, sending blood back to the systemic circulation.
