title: [A case of parotid tumor showing remarkable regression following hyperthermo-chemo-radiotherapy].
abstract: A 72-year-old woman developed adenocarcinoma of the left parotid gland. Because of the excessive size of her tumor and the fact that she suffered from severe liver dysfunction, she was treated by hyperthermo-chemo-radiotherapy (HCR therapy). After ten sessions of radiofrequency hyperthermia with HEH 500 (13.56 MHz radiofrequency wave), 50-Gy irradiation from a linac and administration of 33.0g of tegafur in suppository form, the tumor mass showed remarkable regression decreasing in size by as much as 84% on computed tomography. Histologically the tumor which was resected under local anesthesia, showed almost total necrosis. The multidisciplinary HCR therapy was well tolerated and effective as a therapy for cancer in this case.
