The management of benign and malignant pheochromocytoma and abdominal paraganglioma

Abstract

Aims: To report treatment and outcome in patients with malignant and benign pheochromocytoma and abdominal paraganglioma.Methods: Review of clinical and therapeutic features in 85 patients with pheochromocytoma or abdominal paraganglioma between 1976 and 1999.Results: Thirty-nine of 85 patients presented with symptoms other than classical paroxysmal attacks. Paragangliomas were more often malignant (7/15) than pheochromocytomas (7/70). No recurrences have occurred in 71 patients with tumours initially classified as benign after a median follow-up time of 144 months (range 7–287). Nine of 14 patients with tumours classified as malignant have developed metastasis and/or local recurrence. Treatment of malignant tumours with cyclophosphamide, vincristine and dacarbazine (CVD) improved or stabilised the disease in three of four patients.Conclusion: Life long follow-up of patients with benign pheochromocytoma is not necessary. Combination chemotherapy (CVD) is a valid option in the treatment of malignant pheochromocytomas and abdominal paragangliomas.
