title: [Myocardial hemorrhage due to high-dose cyclophosphamide treatment in a case of non-Hodgkin's lymphoma].
abstract: 43-year-old male with non-Hodgkin's lymphoma which was resistant to standard treatment received high-dose chemotherapy followed by autologous stem cell transplantation. He had a past history of nephrectomy due to renal cell carcinoma. He had received adriamycin at a total dose of 280mg/m2, but had no episode of heart disease. His chest radiograph, electrocardiogram and serum creatinine were within normal ranges at the start of high-dose chemotherapy. He was given 120 mg/kg of cyclophosphamide (CPM) over two days. Serum creatinine levels elevated two days before transplantation, and he felt discomfort of the chest followed by severe arrhythmia. He died of heart failure one day after the transplantation. Postmortem examination revealed diffuse myocardial hemorrhage with degeneration and necrosis of the heart muscle. CPM is one of the useful antitumor alkylating agents for the treatment of malignant neoplasms. Although conventional doses of CPM can be used without adverse cardiac effects, high-dose CPM has been reported to induce cardiotoxicity in a few cases. Patients often develop fatal acute heart failure. For the safe use of high-dose CPM, we must consider about the dosing schedule, early detection of adverse cardiac effects, and patient risk factors.
