Title: 131I-MIBG--a new agent in diagnosis and treatment of pheochromocytoma. Author: Shapiro B, Sisson JC, Eyre P, Copp JE, Dmuchowski C, Beierwaltes WH. Journal: Cardiology; 1985; 72 Suppl 1():137-42. PubMed ID: 4053121. Abstract: The newly developed radiopharmaceutical, 131I-metaiodobenzylguanidine (131I-MIBG), has been shown to be efficacious for the location of intra- and extra-adrenal, primary pheochromocytomas and metastatic, malignant pheochromocytomas (11.4% false-negative and 1.8% false-positive in patients with proven pheochromocytomas). Preliminary experience in selected patients with malignant pheochromocytoma suggest that therapy using large doses of 131I-MIBG results in partial tumor regression and improvement in catecholamine hypersecretion in some cases.[Abstract] [Full Text] [Related] [New Search]
