No results posted yet for this study

Summary

Endobiliary radiofrequency ablation (RFA) with biliary stent has been reported to be a beneficial treatment option for palliation of malignant biliary strictures. RFA uses a high-frequency alternating current to generate heat and achieve coagulative necrosis when in contact with tissue. Within the bile duct, RFA appears to be safe and may result in decreased tumor ingrowth. 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 evaluate the combined effect of RFA and S-1 in patients with unresectable cholangiocarcinoma.

Conditions

Interventions

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.

DRUG

S-1

In the RFA plus S-1 group, treatment with S-1 began within 1 month after RFA. Based on the patient's body surface area, S-1 was administered as follows: when the level of total bilirubin was less than 2 mg/dl. Based on the body surface area, S-1 was administered if \<1.25 m2, 80 mg/day; if 1.25-1.5 m2, 100 mg/day; if≥1.5 m2, 120 mg/day. S-1 was administered orally twice daily for 14 days, followed by 7 days without treatment.

DEVICE

Stent

Plastic stent(s) were placed after RFA depending on the location of the malignant obstruction
