Clinical Trial Summary

Extrahepatic cholangiocarcinoma is a malignant tumor that is highly malignant and difficult to diagnose and treat early. Endobiliary radiofrequency ablation (RFA) has been reported to be a beneficial treatment option for palliation of malignant biliary strictures. Within the bile duct, RFA appears to be safe and may result in decreased tumor ingrowth. To date, little is known about the role of the addition of systemic chemotherapy to RFA for cholangiocarcinoma. The aim of this study is to compare the efficacy and safety of RAF combined with Gemcitabine and S-1 in patients with unresectable cholangiocarcinoma.


Description:

Over 60 % of common bile duct (CBD) obstructions are due to malignancy, and the majority of neoplasms are unresectable at the time of diagnosis. Biliary drainage with placement of metal or plastic stents for palliation is the therapy of choice in this set of patients. Radiofrequency ablation (RFA) is well established method for treatment of some solid tumors, like liver cancer, lung cancer, etc. Recently, an endoscopically applicable radiofrequency probe, HabibTM EndoHBP catheter, was approved for clinical use. RFA uses a high-frequency alternating current to generate heat and achieve coagulative necrosis when in contact with tissue. Many studies showed RFA with biliary stent was a beneficial treatment option for palliation of malignant biliary strictures. However, most of therapeutic effects were expected to delay bile duct obstruction rather than to decrease the tumor. Recently orally available chemotherapeutic agent, S-1, an oral fluoropyrimidine, was reported as effective in patients with bile duct adenocarcinoma. To date, little is known about the role of the addition of systemic chemotherapy to RFA for cholangiocarcinoma. The aim of this study is to compare the efficacy and safety of RAF combined with Gemcitabine and S-1 in patients with unresectable cholangiocarcinoma

Intervention

Device:
radiofrequency ablation
All patients underwent biliary sphincterotomy. Cholangiogram was performed to confirm stricture location, length and diameter. The Habib Endo HPB (Hepatobiliary) probe (EMcision, HitchinHerts, UK) was then advanced over a wire at the level of the biliary stricture and ablation using ERBE generator set at 7-10 watts for a time period of 90-120 s was conducted. A 1- to 2-min resting period after energy delivery was allowed before moving the catheter along the length of the stricture to ablate the rest of the stricture. Plastic stent(s) were placed after RFA depending on the location of the malignant obstruction
Drug:
Chemotherapy drug
Gemcitabine 1 000 mg/m2 intravenously on day 1,8; S-1 80 mg/m2 was taken orally twice for two weeks. The curative effect was evaluated comprehensively for each 2 cycles of chemotherapy
