Malignant pheochromocytoma of the urinary bladder: Effectiveness of radiotherapy in conjunction with chemotherapy

Abstract A 34‐year‐old Japanese man with malignant pheochromocytoma of the bladder underwent surgical resection and chemoradiotherapy for a local recurrence of lymph node metastasis. Radiotherapy seemed to be effective, indicated by the growth inhibition of the irradiated tumor, decreases in serum and urinary catecholamine levels and a clinical improvement in the refractory stage of the combined chemotherapy.
