Patient case: 64-year-old male with Cholangiocarcinoma. Genetic variant: IDH1 (R132H). Other conditions: Neuropathy.

Clinical trial: Stent Placement With or Without Photodynamic Therapy Using Porfimer Sodium as Palliative Treatment in Treating Patients With Stage III or Stage IV Cholangiocarcinoma That Cannot Be Removed By Surgery

Summary: RATIONALE: Stent placement may help reduce symptoms caused by the tumor. Photodynamic therapy uses a drug, such as porfimer sodium, that becomes active when it is exposed to a certain kind of light. When the drug is active, tumor cells are killed. This may be an effective treatment for cholangiocarcinoma. It is not yet known whether stent placement and photodynamic therapy using porfimer sodium are more effective than stent placement alone in treating cholangiocarcinoma.
  PURPOSE: This randomized phase III trial is studying stent placement and photodynamic therapy using porfimer sodium to see how well they work compared to stent placement alone as palliative treatment in treating patients with stage III or stage IV cholangiocarcinoma that cannot be removed by surgery.

Detailed description: OBJECTIVES:
  Primary
  -  Compare the overall survival time in patients with unresectable Bismuth type III or IV, stage III-IV cholangiocarcinoma treated with double plastic endoprostheses insertion with vs without adjuvant photodynamic therapy using porfimer sodium as palliative treatment.
  Secondary
  -  Compare the effect of these regimens on cholestasis in these patients.
  -  Compare the 1-year survival rate in patients treated with these regimens.
  -  Compare health-related quality of life of patients treated with these regimens.
  OUTLINE: This is a randomized, controlled, open-label, multicenter study. Patients are stratified according to participating center.
  Patients undergo endoscopic or percutaneous drainage followed by insertion of bilateral plastic endoprostheses into the bile ducts. Patients are then randomized to 1 of 2 treatment arms.
  -  Arm I: Patients receive porfimer sodium IV on day 1. Patients undergo endoscopic laser light therapy to the tumor site on day 3.
  -  Arm II: Patients receive no further treatment. Quality of life is assessed at baseline and then at weeks 2, 13, 26, 39, 52, and 65.
  After completion of study treatment, patients are followed within 30-90 days.
  PROJECTED ACCRUAL: A total of 120 patients (60 per treatment arm) will be accrued for this study.
