We review here the 10-year experience at the University of Michigan with 35 patients with gastrin hypersecretion who underwent transhepatic venous sampling (THVS) for tumor localization. Since 1978 THVS has been done routinely in all patients with gastrinoma syndrome considered for operation. Thirty-one patients had proved gastrinomas--21 benign sporadic tumors and 10 tumors associated with multiple endocrine neoplasia type-I (MEN I) syndrome. The correlation between the site of the maximal gradient and location of a sporadic tumor was poor. Overall sensitivity was only 35%, specificity 89%, and negative predictive value 89%. If gradients were regionalized to three areas--body and tail, gastrinoma triangle, and hepatic lobes--then sensitivity was 94%, positive predictive value 94%, and specificity 97%, with a negative predictive value of 97%. The maximal gastrin gradient above the mean for other values gave the greatest sensitivity and specificity. In MEN I syndrome, only four of eight patients with macroadenomas had their tumors correctly localized, a sensitivity of 50% and specificity and negative predictive value of 75%. In 19 patients who had operative localization of sporadic gastrinoma, computed tomography had a sensitivity of 31%, specificity of 66%, positive predictive value of 83%, and negative predictive value of 15%. Selective angiography was better, with a sensitivity of 29%, specificity of 100%, positive predictive value of 100%, and negative predictive value of 100%. Regionalization to the triangle proved valuable for detection of microgastrinomas, as was measurement of hepatic vein gastrins for identification of intrahepatic tumors. In MEN I syndrome, if regionalization was achieved (50%), tumor resection appeared to offer hope of "cure." We conclude that THVS is the best tool for tumor regionalization to the pancreatic tail and body, gastrinoma triangle, and hepatic lobes. It has allowed us to achieve surgical cure in 19 of 21 patients with sporadic gastrinomas and improvement in four of eight patients with MEN I syndrome.

D009377	Multiple Endocrine Neoplasia	A group of autosomal dominant diseases characterized by the combined occurrence of tumors involving two or more ENDOCRINE GLANDS that secrete PEPTIDE HORMONES or AMINES. These neoplasias are often benign but can be malignant. They are classified by the endocrine glands involved and the degree of aggressiveness. The two major forms are MEN1 and MEN2 with gene mutations on CHROMOSOME 11 and CHROMOSOME 10, respectively.

D010190	Pancreatic Neoplasms	Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).
