High-Dose-Rate Remote Afterloading Intracavitary Br achy therapy for the Treatment of Extrahepatic Biliary Duct Carcinoma

Abstract

High dose rate brachytherapy of 21 Gy in three divided weekly treatments, plus 45 Gy of external beam radiation is well tolerated. A dose response is shown with significant increase of PR and CR rate for dose >59 Gy. This modality of treatment appears to be safe and effective for inoperable extrahepatic biliary duct carcinoma.
