Comparing treatments for bile duct cancer

Clinical Effect and Safety of Photodynamic Therapy Versus Radiofrequency Ablation Versus Photodynamic Therapy Plus Radiofrequency Ablation for Unresectable Extrahepatic Cholangiocarcinoma

Not applicable Interventional First People's Hospital of Hangzhou · NCT05519319

This study is testing which treatment—photodynamic therapy, radiofrequency ablation, or a mix of both—works best for people with bile duct cancer that can’t be surgically removed.

What this trial studies

This study evaluates the safety and efficacy of three treatment approaches for extrahepatic cholangiocarcinoma: photodynamic therapy (PDT), radiofrequency ablation (RFA), and a combination of both. Patients with unresectable cholangiocarcinoma will be treated to assess which method best improves stent patency and overall survival. The study aims to fill a gap in existing literature by directly comparing the clinical outcomes and adverse effects of these two endoscopic procedures.

Who should consider this trial

Good fit: Ideal candidates are patients with histologically confirmed unresectable extrahepatic cholangiocarcinoma who have not received prior treatment.

Not a fit: Patients with distant metastasis or other concurrent malignancies may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide patients with a more effective treatment option that improves survival and quality of life.

How similar studies have performed: While there is evidence supporting the effectiveness of PDT and RFA individually, this direct comparison is relatively novel and has not been extensively tested.
