简要总结
Photodynamic therapy (PDT) is a combination of a drug, porfimer sodium (Photofrin), which is activated by a light from a laser that emits no heat. This technique works to allow the medical doctor to specifically target and destroy abnormal or cancer cells while limiting damage to surrounding healthy tissue. The activation of the drug is done by lighting the abnormal areas using a fiber optic device (very fine fiber like a fishing line that permits light transmission) inserted into a flexible tube with a light called cholangioscope for the bile duct. The light will activate the porfimer sodium concentrated in the abnormal tissue, leading to its destruction.
This research study will evaluate the efficacy and safety of PDT with porfimer sodium administered with Standard Medical Care (SMC) compared to SMC alone on the overall survival time of patients with non-operable advanced cholangiocarcinoma, a rare cancer of the bile ducts. It will involve 200 patients across North America and Europe. Other countries may participate if needed. Participation will last at least 18 months.

Photodynamic therapy (PDT) is a combination of a drug, porfimer sodium (Photofrin), which is activated by a light from a laser that emits no heat. This technique works to allow the medical doctor to specifically target and destroy abnormal or cancer cells while limiting damage to surrounding healthy tissue. The activation of the drug is done by lighting the abnormal areas using a fiber optic device (very fine fiber like a fishing line that permits light transmission) inserted into a flexible tube with a light called cholangioscope for the bile duct. The light will activate the porfimer sodium concentrated in the abnormal tissue, leading to its destruction.
Cholangiocarcinoma (CCA) is defined as primary malignant tumors of the bile ducts. The exact etiology remains unknown. These cancerous tumors block the bile flow and can be intrahepatic (IH) or extrahepatic (EH). The distinction between IH- and EH-CCA has become increasingly important, as the epidemiological features (i.e., incidence and risk factors), the biologic and pathologic characteristics and the clinical course are largely different. Unfortunately, most subjects are found to have metastases or unresectable disease at the time of diagnosis. Median survival for subjects with unresectable perihilar-CCA varies between five and eight months. The one-year survival is 50%, with 20% surviving at two years and 10% at three years. Unresected CCA is a rapidly fatal process with cholangitis being a significant cause of morbidity and mortality in these subjects.
This study was designed to confirm the efficacy of PHOPDT + standard medical care (SMC) defined as stents plus gemcitabine/cisplatin chemotherapy regimen on the overall survival of subjects with unresectable cholestasis perihilar Bismuth type III or IV - tumor TNM stage III or IVa CCA.

研究组 & 干预措施
Photodynamic therapy-Photofrin plus SMC
Photodynamic therapy (PDT) involves the i.v. injection of Photofrin followed by the illumination of the tumor using a fiber optic device. Two days after the injection, a laser light (180 J/cm(2)) will be applied to the tumor. A second light application will be given 96-120 hours after Photofrin injection if PDT could not initially be performed on all sides of the tumor. Post illumination, all patients will undergo stenting as part of standard medical care procedure. Up to 3 additional courses of PDT using a light dose of 120 J/cm(2) may be given at 3-month intervals. Standard Medical Care (SMC) is defined as stenting procedure plus chemotherapy regimen.

Standard Medical Care (SMC)
Standard Medical Care (SMC) is defined as stenting procedure plus chemotherapy regimen. The chemotherapy regimen will comprise gemcitabine (1 000 mg/m(2)) followed by cisplatin (25 mg/m(2)), each administered on days 1 and 8 every 3 weeks (21 day-cycle) for four cycles. An additional 12 weeks of the same chemotherapy regimen may be administered if there is no disease progression or intolerable toxicity.
