| Research Abstract |
The thermal treatment is one of the modalities for cancer treatment, utilizing the difference of thermal sensitivity between tumor and normal tissue. There are a few methods for heating the cancer cells inside the body. In this study, intracavitary heating is employed for treatment. In this treatment, a long flexible microwave antenna is inserted into the forceps channel of the endoscope and is led to the bile duct. In this study specifications of the microwave antenna such as diameter and length of the antenna were decided based on results of animal experiment. Moreover, the antenna structure was improved by opinion of medical doctors. In addition, heating characteristics of the antenna inserted into a metallic stent, which is frequently employed for treatment of bile duct carcinoma, could be investigated. As a result, some effective characteristics for the heating of this situation were found.
