PLSMA AND TUMOR GASTRIN IN PATIENTS WITH PRIMARY HYPERPARATHYROIDISM
It is well known that primary hyperparathyroidism is often associated with peptic ulcer. The purpose of this study is to confirm the relationship between the gastrin-levels before and after parathyroidectomy in fourteen patients with primary hyperparathyroidism, and to determine the localization of gastrin in the surgically resected parathyroid tumor. The results obtained were as follows: 1)Three patients had peptic ulcer(gastric ulcer and duodenal ulcer), the incidence being 21%. 2) The basal serum gastrin levels were 123.0%±68.1pg/ml before operation and decreased to 90.2±44.5pg/ml after operation. In the 3 patients with sightly elevated gastin levels, the mean level before operation was 209.1±61.2pg/ml. The gastrin level decreased to 116.4±62.0pg/ml after operation. 3) Gastrin immunoreactivity was detected in 10 out of 14 tumors and its localization was at the periphery of tumor cells.
From these results, we conclude that extragastric gastrin secretion from parathyroid tumors may be one of the cause of peptic ulcer in patients with primary hyperparathyroidism.
