Radiation therapy

External radiation therapy: A machine outside the body sends radiation toward the area of the body with cancer. Radiation is given in a series of treatments to allow healthy cells to recover and to make radiation more effective. The number of treatments is based on details about the cancer, such as the size and location of the tumor. It is not known whether external radiation therapy helps in the treatment of resectable bile duct cancer. In unresectable, metastatic, or recurrent bile duct cancer, new ways to improve the effect of external radiation therapy on cancer cells are being studied:

Hyperthermia therapy: Body tissue is exposed to high temperatures to make cancer cells more sensitive to the effects of radiation therapy and certain anticancer drugs.

Radiosensitizers: Drugs called radiosensitizers make cancer cells more sensitive to radiation therapy. Combining radiation therapy with radiosensitizers may kill more cancer cells.

Internal radiation therapy: A radioactive substance is sealed in needles, seeds, wires, or catheters that are placed directly into or near the bile duct.
