高カルシウム血症による臨床症状を随伴した腎腫瘍の1例

Abstract

A 71-year-old man noticed gross hematuria two months before he consulted a doctor. IVP and angiogram showed an enlarged kidney and metastatic tumor. A diagnosis was made as renal cell carcinoma with metastatic tumor. As curative operation could not be performed, chemotherapy was started. Three months later, he had trans catheter embolization in order to degenerate primary and metastatic tumors. One month later, clinical manifestations of hypercalcemia appeared. He was given a three week course of calcitonin 160 U intramuscularly. As symptoms and signs of hypercalcemia improved, medical treatment was stopped. Since clinical manifestations of hypercalcemia appeared again about one week later, intravenous transfusion of calcitonin 80-160 U was resumed for one month. The condition of hypercalcemia was significantly reduced. There was no adverse reactions of calcitonin.
