[Radiation therapy of malignancies of the digestive organs].
Malignancies of digestive organs have been treated, as a first choice, by surgery, and conventional fractionated radiotherapy has been palliatively applied to those inoperable or recurrent cases. IOR and intracavitary radiotherapy, which made it possible to give large dose of well localized irradiation to the lesions, are now available in combination with surgery or on its own. Here mentioned the IOR of pancreas, biliary tract, stomach and rectum, and also discussed the intracavitary radiotherapy of esophagus and biliary tract.
