PDT plus radioactive biliary stent for unresectable extrahepatic cholangiocarcinoma

Official title: A Clinical Study on the Application Value of Photodynamic Therapy Combined With a Self-expandable Radioactive Particle-loaded Biliary Stent in Unresectable Extrahepatic Cholangiocarcinoma

Run by The First Affiliated Hospital of Zhengzhou University · NCT07916870 · Data updated 2026-11-12

This study tests whether combining photodynamic therapy with a self-expandable radioactive stent can help patients with unresectable extrahepatic cholangiocarcinoma stay cancer-free longer and keep their bile ducts open.

Is this trial a fit for you?

Likely a good fit

Adults (≥18) with histologically, cytologically, or radiologically confirmed unresectable extrahepatic cholangiocarcinoma who cannot undergo surgery and meet the study criteria.

Probably not a fit

Patients with allergy to photosensitizers, severe organ dysfunction, active biliary infection, or very limited life expectancy may not benefit.

What this trial studies

This is a prospective, single-arm interventional study enrolling adults with unresectable extrahepatic cholangiocarcinoma. After initial biliary drainage, a photosensitizer is given and, 48–72 hours later, PDT is performed under imaging guidance. Subsequently, a self-expandable biliary stent loaded with Iodine-125 is implanted to provide ongoing local brachytherapy and maintain biliary patency. The primary outcome is tumor response or biliary patency by RECIST v1.1, with safety and follow-up as secondary considerations. The approach aims to synergize tumor destruction from PDT with continuous local irradiation to slow progression.

Why it matters

Potential benefit: If successful, patients may experience longer biliary patency and potentially improved survival.

How similar studies have gone: Early results from similar approaches suggest potential benefit, but this specific combination with a radioactive biliary stent is exploratory and not yet proven.
