Prognostic Value of Baseline Systemic Immune-Inflammation Index in Advanced Intrahepatic Cholangiocarcinoma Treated with First-Line Gemcitabine-Cisplatin Plus PD-L1 Inhibitor: A Single-Center Retrospective Study.

ABSTRACT:

Background

Gemcitabine-cisplatin (GC) combined with a programmed death-ligand 1 (PD-L1) inhibitor has become an important first-line regimen for advanced intrahepatic cholangiocarcinoma (ICC). However, overall efficacy remains modest, and inter-patient heterogeneity in outcomes is substantial, highlighting the need for simple biomarkers for pretreatment risk stratification. The systemic immune-inflammation index (SII), derived from peripheral neutrophil, lymphocyte, and platelet counts, has been associated with prognosis in various malignancies, but its clinical relevance in advanced ICC treated with first-line GC plus PD-L1 inhibitor remains unclear.

Aims

To evaluate the association of baseline SII with objective response and survival outcomes in patients with advanced ICC
