title: [A CR case of amylase-producing tumor treated by hyperthermochemotherapy].
abstract: A 64-year-old female who was diagnosed with an amylase-producing tumor of unknown origin was treated by hyperthermochemotherapy. The patient was admitted with a complaint of abdominal fullness due to ascites. Laboratory examination showed high levels of serum amylase and tumor markers, including CA15-3, CA 125 and CA 72-4. Laparotomy showed peritoneal dissemination with histological findings of adenocarcinoma of unknown origin. After laparotomy, she was given hyperthermia combined with chemotherapy using carboplatin (CBDCA), mitomycin C (MMC) and doxifluridine (5'-DFUR). Hyperthermia (13.56 MHz radiofrequency for 40-50 min) was performed a total of six times within one and a half months. The total doses of CBDCA and MMC were 450 mg and 24 mg, respectively, and 600 mg of 5'-DFUR was orally administered every day. By these combined treatments, ascites disappeared and serum levels of amylase and all tumor markers were decreased and normalized. MRI and echo examination also showed complete disappearance of peritoneal metastasis. Two and a half years after the treatment, the patient is alive without any evidence of recurrence, which suggests that this combined therapy is one of the useful modalities for peritoneal dissemination as well as an inoperable tumor itself.
