Safety and Efficacy of PDT vs RFA vs PDT+RFA for the Treatment of Extrahepatic Cholangiocarcinoma

A median survival period of 3 to 6 months is the prognosis for patients with advanced, unresectable EHCC. For patients with locally advanced, unresectable EHCC, effective management of tumor growth is the only option to increase stent patency and survival time. In patients with cholangiocarcinoma, photodynamic therapy (PDT) is therapy that has been shown to improve stent patency and overall survival (OS). Endoscopic radiofrequency ablation (RFA) has been demonstrated in numerous studies to prolong the life spans of individuals with malignant biliary obstruction . In the literature, comparing the clinical efficacy and adverse outcomes of these two endoscopic procedures is rare.
