The role of prostaglandins in endocrine diarrheagenic syndromes was evaluated by measuring peripheral concentration of immunoreactive PGE and PGF in patients with non-endocrine diarrhea as well as those with the Zollinger-Ellison (Z-E) syndrome, MCT, carcinoid tumors and the WDHA syndrome. In 21 normals, PGE and PGF levels averaged 272 +/- 18 and 119 +/- 14 pg/ml, respectively. Twenty eight patients with diarrhea of non-endocrine origin (mainly inflammatory bowel disease) had levels indistinguishable from normal, i.e. 353 +/- 25 and 77 +/- 37 pg/ml, respectively. Among 29 patients with the Zollinger-Ellison syndrome (mean gastrin 6127 +/- 3267 pg/ml) only 2 had significantly elevated PGE levels; mean PGE levels, 382 +/- 32 pg/ml, were not significantly different from normal and did not correlate with either diarrhea or the serum gastrin concentration. In contrast, 18 of 22 patients with carcinoid tumors (mean blood serotonin concentration 1655 +/- 604 ng/ml; mean urinary excretion of 5 HIAA 66.8 +/- 16.7 mg/day) had elevated peripheral concentrations of PGE. The mean PGE level (1367 +/- 245 pg/ml) was significantly elevated (P less than 0.001). Nonetheless PGE levels did not correlate with diarrhea, blood concentrations of serotonin, or urinary indole excretion. MCT (mean serum calcitonin 24.5 +/- 6.3 ng/ml) was similarly associated with consistent (18/19) elevation in peripheral concentrations of PGE (mean 1922 +/- 541 pg/ml; P less than 0.001). Inthis syndrome, PGE levels were higher in patients with diarrhea and in those with markedly elevated serum thyrocalcitonin levels. Finally, 8 of 21 patients with the WDHA syndrome had increased levels of PGE. Although 13 of 17 patients had high levels of VIP (mean 8133 pg/ml), 2 patients had hyperprostaglandinemia in the face of normal peripheral concentrations of VIP. In one patient the serum PGE level was elevated prior to resection of the primary pancreatic neoplasm (9939 pg/ml) as well as the subsequent extirpation of a solitary hepatic metastasis (1063 pg/ml); following each procedure the diarrhea abated and the PGE level returned to normal. In none of these syndromes were mean PGF levels elevated. The study has documented hyperprostaglandinemia in some endocrine diarrheagenic syndromes and validated the usefullness of measurements of PGE in patients with unexplained diarrhea.

The authors report the observation of a 70 years male with Cutis Verticis Gyrata (without hypertrophying osteopathy), Menetrier's hypertrophic gastritis, motrice diarrhea of the endocrine type, flush syndrom, liver angiomatosis and a large sacral water clear cells tumor with horse's tail syndrom. The initial tumor was on the posterior wall of rectum, but was necrosed : bone metastasing chemodectoma, or locally invading carcinoid ? This new complex paraneoplastic disease seems to be associated with APUD tumor.

Eighteen patients with metastatic carcinoid tumours were admitted to surgical gastroenterological department of Rigshospitalet during the period 1974--1978. Thirteen had primary carcinoid tumours in the terminal ileum, two in the lungs, one in the pancreas, one in the testis, and one possibly in the retroperitoneum. All patients had distant metastases, 13 in the liver. Carcinoid syndrome with flusing and diarrhoea was present in 15 patients (83%). The time elapsing from onset of symptoms until diagnosis was on an average 2 1/2 years. The most valuable screening test for carcinoid syndrome was determination of the excretion of 5-hydroxy-indol- acetic-acid. The most sensitive investigation for determination of primary tumour and/or metastases was abdominal angiography, which was positive in all cases. Other radiological investigations were less sensitive.

The clinicopathologic features are presented of 8 malignant neoplasms occurring in adult teratomas, and of 2 malignant monodermal teratomas found in a continuous series of 1029 cases of ovarian adult teratomas. The age of the patients was 44--76 years. The first 8 observations included 6 epidermoid carcinomas, 1 undifferentiated carcinoma and 1 strumal carcinoid. In the epidermoid carcinomas malignancy was recognized peroperatively only in three instances. One tumor had infiltrated the broad ligament on one side and another the urinary bladder. The neoplasm appeared as a mass which thickened the wall of a typical dermoid cyst. Four patients died of the tumor from 3 months to 1 year after operation; one is alive more than 19 years later and one is lost to follow-up. The crucial factor in prognosis is the integrity of the ovarian capsule. The undifferentiated carcinoma, which had infiltrated the pelvic walls, could only be incompletely resected and caused death within 3 1/2 months. The strumal carcinoid was discovered by chance during laparotomy for a far-advanced adenocarcinoma of the pancreas which led to death within 2 months. The two cases of malignant monodermal teratoma comprised 1 thyroid papillary carcinoma and 1 carcinoid. Both patients are alive more than 8 and 5 years after operation. The carcinoid manifested itself by persistant diarrhea which ceased soon after operation and did not recur subsequently.

N-(Phosphonacetyl)-L-aspartic acid, an inhibitor of aspartate transcarbamylase, was administered to 25 patients with advanced cancer by 10-minute infusion daily x 5 consecutive days to determine the toxicity and to look for evidence of therapeutic effect. Planned dose escalations ranged from 100 to 1250 mg/m2 (daily dose). Nausea, vomiting, and diarrhea were the most frequent toxic effects, with three of six patients treated at a daily dose of 1250 mg/m2 having severe diarrhea. Other toxic effects were encountered rarely and were not dose-limiting; these included mild leukopenia, thrombocytopenia, rash, stomatitis, and increases in SGOT. One patient with a widely metastatic carcinoid of unknown origin had an objective response lasting 6 weeks.

The treatment of thirty-one malignant and eleven benign neoplasms of the small intestine is reported. The most common symptom was abdominal pain followed by vomiting, diarrhea, weight loss, constipation, and gastrointestinal bleeding. In four cases small bowel perforated. Intestinal obstruction occurred in 31 per cent of patients. Preoperative diagnosis was made in 19 per cent of patients. All eleven patients with benign neoplasms were curatively treated by resection and primary anastomosis. Eighteen of the thirty-one patients with malignant tumors had curative resection, five had palliative resection, and eight had laparotomy and biopsy only. The most common benign tumor was leiomyoma. The most common malignant tumor was lymphoma (67 per cent) followed by adenocarcinoma (16 per cent), carcinoid (10 per cent), and leiomyosarcoma (3 per cent). Twenty-four patients were available for follow up; thirteen remain alive and eleven died, seven within one year and four within two years.

Casuistically is reported on two patients with an endocrine inactive ileum carcinoid, in whom the anamnesis with 5 weeks or 10 months was very short and atypical. Continuously increasing abdominal pain and gradual formation of a lower ileus of the small intestine or profuse watery diarrhoeas were the leading symptoms. Intraoperatively or autoptically in each case a very small (less than 1.5 cm) ileum carcinoid was found, which had led to a stenosing of high degree, there were no fibroses of the endocardium, no liver metastases--accordingly the secretion of serotonine metabolites (5-HIES) in the urine had been normal. The possibility of a so-called endocrine-nervous enteropathy in the female patient with the diarrhoea symptomatology and the necessity of a rapid diagnostic clarification in suspicion of a tumour in the lower small intestine are discussed, since such a suspicion in most cases corresponds to a carcinoid and thus there exists a great chance of cure.

The authors report an analytic study of hydroelectrolytic disorders in patients with APUD tumors. In most of the cases a diarrhea occurs. The type of this diarrhea is: -- a motrice diarrhea (in the great majority of carcinoid tumor and medullary carcinoma of the thyroid); -- a secretory diarrhea (W.D.H.A.): it is the case in gastrinoma (gastric hypersecretion), in secretinoma (pancreatic hypersecretion) and in vipoma (intestinal hypersecretion). The others disorders could be no diarrhea dependant (hyponatremia by ADH hypersecretion, hypercalcemia). The personal cases of the authors are: 12 medullary carcinoma of the thyroid, 19 enteraminoma and 2 others apudomas.

The radiological workup of 15 patients with a carcinoid has been evaluated. As 7 of the 15 patients presented for emergency operation, only the remaining 8 had barium studies (7 barium meals and 1 barium enema). Two of the barium meals were even retrospectively, entirely negative. In two others, initially the diagnosis was missed despite radiological signs, which had been overlooked on follow-up films. Fluoroscopic examination of the small bowel would probably have ensured the detection of the lesion. At the time of diagnosis nine tenth of the tumours were already infiltrating and more than half of them metastasizing. The presence of the carcinoid syndrome implies the production of the causative hormones in the liver or the pulmonary circulation. In order to find the primary intestinal carcinoid in a cureable stage- that is, before it has metastasized-, all patients with diarrhoea and repeated bouts of abdominal pain should have a careful follow-up examination of the small bowel. This examination must include fluoroscopies.
