Outline of Final Research Achievements

Up to now, we have investigated the thin microwave antenna for non-invasive thermal treatment of bile duct carcinoma. Meanwhile in many cases, a metallic stent is employed for the treatment of bile duct carcinoma. The metallic stent improves stricture by expanding it physically. However, in many cases recurrent stenosis will be incurred by explosive growth of the cancer cells. In this case, the thermal treatment by the microwave energy may be effective. Here, according to our previous study, the microwave antenna inserted into the metallic stent cannot radiate the microwave energy to outside of the stent, where the cancer cells are existing. This is because the electromagnetic wave is shielded by the metallic stent. So, in this study, effective microwave heating under the stent placement have been investigated. As a result of investigations, several effective findings were obtained.
