Core Tip
Core tips: Radiotherapy has been administered for extrahepatic bile duct cancer patients in adjuvant, definitive, or palliative settings. The evidence in support of radiotherapy is derived from retrospective studies because there is a lack of randomized controlled trials. This review aimed to summarize contemporary series involving radiotherapy treatment for extrahepatic bile duct cancer. These data and findings were then used to propose strategies for generating robust evidence for or against the use of radiotherapy for this disease.
