[Intra and extra hepatic cholangiocarcinomas radiation therapy]

Cholangiocarcinomas are digestive tumors whose incidence remains low and have poor prognosis. The benefits of adjuvant radiochemotherapy and radiotherapy have never been demonstrated in any phase III randomized controlled trial. Chemotherapy with capecitabine 6 months is the standard of care in adjuvant setting. Radiochemotherapy is validated in R1 patients. It is not recommended in neoadjuvant situations given the lack of evidence. Chemotherapy and radiochemotherapy are validated in adjuvant or locally advanced diseases. Stereotactic radiation therapy offers an interesting perspective, at the cost of significant digestive toxicities, requiring evaluation in randomized trials.
