We present a case report on a 35-year-old patient in whom a malignant sympathetic paraganglioma of the organ of Zuckerkandl was the cause of severe hypertension with excessive perspiration at night. Since curative surgery was not possible medical treatment was initiated. Interferon alfa 2b (Intron A, Essex Pharma) and the somatostatin-analogue SMS 201-995 (Sandostatin, Sandoz) had no effect on catecholamine production and progression of the tumor. Treatment with alpha-methyl-para-tyrosin (MPT, [Metyrosin], Demser, MSD) turned out to be an effective and well tolerable therapy in this patient with peritoneal carcinosis. Clinical and hormonal progression of the paraganglioma resumed only after two years of therapy, which constitutes the longest documented period of time of successful MPT treatment. The superior efficacy of MPT in our patient should encourage postoperative medical treatment with MPT in malignant pheochromocytoma or malignant paraganglioma, particularly when the tumor turns out to be resistent to alpha blocking drugs.

A 69 year-old male with carcinoid syndrome and undetectable primary tumour, but disseminated liver metastases, was treated with somatostatin analogue octreotide (Sandostatin) and later additionally with recombinant interferon alpha 2 b (r IFN alpha 2 b, Intron A). The carcinoid symptoms (flushing, diarrhoea) were stopped within hours by octreotide. Simultaneously, the urinary 5-hydroxyindolacetic acid (5-HIAA) excretion and serum serotonin levels decreased by more than 50%. In spite of continued treatment with r IFN alpha 2 b a reduction in dosage of octreotide resulted in a rapid recurrence of carcinoid symptoms, suggesting that IFN alpha 2 b had no effect on the carcinoid symptoms in this patient. Since, furthermore, no regression of the tumour mass was observed, treatment with IFN was stopped after 8 months. During 15 months of treatment to date the patient has been kept free of symptoms by octreotide.
