Research Article: Prognostic Value of Systemic Immune-Inflammation Index-Based Nomogram in Patients with Extrahepatic Cholangiocarcinoma Treated by Percutaneous Transhepatic Biliary Stenting Combined with I Seed Intracavitary Irradiation
Introduction:
Cholangiocarcinoma (CCA) is a highly malignant and aggressive tumor that originates from the epithelial cells of bile duct. According to the anatomical location, CCA is classified into intrahepatic cholangiocarcinoma (ICC) and extrahepatic cholangiocarcinoma (EHCC), and of which EHCC accounts for –%.
