Photodynamic Therapy (PDT) Cholangiocarcinoma Registry (PDTRegistry)
To Establish a Multicenter Registry to Evaluate the Impact of Photodynamic Therapy in the Management of Patients With Unresectable Cholangiocarcinoma.
Currently, very few centers offer Photodynamic therapy for unresectable Cholangiocarcinoma in the United States. Several European studies have reported the efficacy and safety of Photodynamic Therapy (PDT) for Cholangiocarcinoma, however, only a few studies have reported the same in the United States.
The establishment of a registry to capture all PDT cases within and outside US can help the investigators evaluate a larger and non-ambiguous sample population. This would help the investigators evaluate the technical success rates, clinical success rates, feasibility and safety of PDT for unresectable cholangiocarcinoma. With more endoscopists considering PDT as a therapeutic option along with adjuvant treatment for cholangiocarcinoma, there is a need to further evaluate the efficacy and safety of such combined procedures as well. The ultimate objective is to assess if PDT with or without additional or adjuvant treatment options prolongs survival duration and improves quality of life in patients with unresectable cholangiocarcinoma.
This multicenter registry has been initiated:
- To document the impact of PDT on the clinical management of unresectable cholangiocarcinoma.
- To assess the clinical and technical success rates of PDT for unresectable cholangiocarcinoma.

Detailed Description
PDT offers a number of practical advantages; it is minimally invasive and has a low complication rate, the procedure can easily be performed by a trained endoscopist, and it is well tolerated. In the trial conducted in Germany, the adverse events of PDT were mild to moderate, predictable, and relatively easy to control. Photosensitivity was the only systemic side effect (seen in only three patients). However, provided that simple guidelines for light exposure are followed, there is minimal risk to the patient, as shown by the low incidence of photosensitivity reactions in this study which all resolved.
A study from the Mayo group included 25 patients with unresectable cholangiocarcinoma who were treated with PDT from 1991 to 2004 showed that the time interval between diagnosis and treatment with PDT is an important predictor of survival following PDT even when adjusted for other potential factors that affect survival such as age, gender, Bismuth stage, presence of tumor mass on imaging and presence of extra biliary spread. Early treatment with PDT may lead to greater preservation of liver function. A recent study by the primary investigator has also recently reported improved survival in patients receiving PDT and stent compared to stent only (16.2 months vs 7.4 months).
Several other European studies have reported the efficacy and safety of PDT for cholangiocarcinoma; however, only a few studies have reported the same in the United States. This is again due to the fact that PDT is not offered as a therapeutic option for unresectable cholangiocarcinoma within US.
However, the establishment of a registry to capture all PDT cases within and outside US can help the investigators evaluate a larger and non ambiguous sample population. This would help the investigators evaluate the technical success rates, clinical success rates, feasibility and safety of PDT for unresectable cholangiocarcinoma.
The involvement of international sites is crucial, as the advanced endoscopists all over the world are offering photodynamic therapy for managing unresectable cholangiocarcinoma. However, because of the non-existence of a registry, and the fact that PDT is not offered in more than a few centers in the US; these cases are often reported with a smaller sample size. The registry hopes to combine all such comparable cases and collect enough relevant data for statistical analyses.
With more endoscopists considering PDT as a therapeutic option along with adjuvant treatment for cholangiocarcinoma, there is a need to further evaluate the efficacy and safety of such combined procedures as well. The ultimate objective is to assess if PDT with or without additional or adjuvant treatment options prolongs survival duration and improves quality of life in patients with unresectable cholangiocarcinoma.

Photodynamic therapy
Subjects who will receive photodynamic therapy for palliation of unresectable Cholangiocarcinoma.
|
PDT is a therapeutic approach that specifically targets neoplastic cells. • PDT involves three components:
Technique: Subjects will be injected with Photofrin or similar drug. 3 days post injection, the subject will receive photodynamic therapy during an Endoscopic Retrograde cholangiopancreatography (ERCP) procedure. Subject will undergo stenting as part of standard of care procedure post photodynamic therapy. Subject may undergo multiple photodynamic therapy sessions with a gap of at least 3 months.
