Intraluminal high dose rate brachytherapy in the treatment of bile duct and gallbladder carcinomas.

BACKGROUND/AIMS: The prognosis of biliary tract carcinomas is poor, and therapeutic efforts are limited mostly only to palliation. The aim of this study was to retrospectively evaluate the effectiveness and tolerability of intraluminal high dose rate brachytherapy in the treatment of bile duct and gallbladder carcinomas. METHODOLOGY: Thirteen patients with bile duct and gallbladder carcinomas were treated by brachytherapy administered through high dose rate remote afterloading system. Five patients after Roux-en-Y hepaticojejunoanastomosis were treated by intraluminal brachytherapy inserted via a diahepatal drain, and 8 inoperable patients were treated by intraluminal brachytherapy via a percutaneous biliary drain. RESULTS: After intraluminal brachytherapy, a control of icterus was observed in all patients. The treatment was well tolerated and mean survival was 275 days. CONCLUSIONS: The addition of intraluminal brachytherapy may be beneficial to patients with carcinomas causing biliary obstruction in whom bile drainage can be established.
