[Veno-occlusive syndrome with acute liver dystrophy following decarbazine therapy of malignant melanoma (author's transl)]

Abstract

Case report about death due to veno-occlusive liver disease following Dacarbazine treatment: 9 years after surgical treatment of malignant melanoma of the trunk a 68-years old patient developed lymph node metastases in the right axilla, which were removed immediately by surgical excision. One month before the patient had undergone surgical treatment of empyema of the gallbladder: Cholecystectomy and appendectomy were performed, postoperative recovery was uncomplicated. On account of the second lymph node metastasis within nine months adjuvant treatment with Dacarbazine was agreed and started one month later. After having performed the first course of treatment without any hints to intolerance the patient suddenly exhibited severe shock symptoms on the fourth day of the second course. Clinically residual myocardial infarct or pulmonary embolism were assumed, but could not be verified. The patient delivered increasing hepatomegaly. A massive increase in transaminase values was noted. Hemostasiologic changes with decreased Quick value occurred. The patient died of cerebral hemorrhage five days after beginning the second Dacarbazine cycle. Autopsy findings were severe liver cell necroses as well as liver vein thromboses, no metastases of melanoma could be found. Hepatotoxicity of Dacarbazine and the mechanism of liver vein thrombosis are discussed with special regards to possible hemostasiologic changes and sensibilisation due to Dacarbazine and/or previous liver cell damage.
