Core Tip

Core Tip: Intraluminal brachytherapy (ILBT) is an effective means for palliation of biliary obstruction in patients with cholangiocarcinoma. It delivers a high dose of radiation to the tumor but spares surrounding normal tissues, thus avoiding many of the side effects seen with external beam radiation. The high dose per fraction in ILBT can have an ablative effect on the tumor and can lead to better symptom control and quality of life. ILBT, when combined with these drainage procedures, improves the stent patency rates by inhibiting tumor ingrowth.
