We present a retrospective study of twenty patients in whom bronchial carcinoids, and five, peripheric. One case met the criteria of atypical carcinoid. The mean age of presentation was 46.66 +/- 17.07 years (15-76), with predominance of the female gender (3:2). Twenty per cent of patients were asymptomatic and in the remainder, the diagnosis suffered an average delay of 19 months since the appearance of symptoms. Such symptoms were cough (50%), recurrent pneumonias (40%), fever (35%), hemoptysis (35%), thoracal pain (30%), carcinoid syndrome (10%) and consumptive syndrome (5%). The radiology showed lobular or segmentary atelectasis (40%), nodule/mass (30%), lobular or segmentary consolidation (20%), obstructive pneumonitis (5%) and atypical pleural effusion (5%). Direct endoscopic vision offered a sensitivity of 84.6%, while transbronchial biopsy, just 69.2%. Metastasis in mediastinal, suprarenal, thyroid and brain gangliar chains were detected.

A total of seven patients with bronchial carcinoids were treated at our hospital during the period from 1975 to 1991. Debut of symptoms varied from eight months to ten years before diagnosis. Cough, copious mucus, hemoptysis and recurrent lobar pneumonias were common. Six tumours were identified by chest X-ray. All tumours were visualised bronchoscopically; five showed as cherry-red polypoid tumours, one as a necrotising tumour and one as a stenosis of the bronchus. One patient underwent pneumonectomy, three lobectomy, one bilobectomy, one segment resection and one sleeve resection and lobectomy combined. Two cases were complicated by empyema and one was not radically operated due to impaired cardiopulmonary function. None showed carcinoid syndrome. All patients are still alive, and no recurrences or metastases have appeared.

Thirty-three bronchial carcinoid tumours operated on in a 22-year period are reviewed. They were histologically verified as typical carcinoids with Grimelius' argryophilic staining (25 cases), electron microscopy (6) and immunostaining for synaptophysin (4). Nineteen were endobronchial and 14 peripheral, intraparenchymal tumours. Lymph-node metastases were present at operation in two patients. Two tumours, in patients with Cushing's syndrome, were hormonally active (one secreting ACTH and the other ACTH and calcitonin). There was one case of multiple endocrine neoplasia syndrome, but none of carcinoid syndrome. During follow-up for 5-18 (mean 8.2) years five patients died of unrelated causes. Only one patient showed distant metastasis (after 15 years in salivary gland and a year later in mediastinal fat). Extensive clinical re-examination was performed on 20 patients, and six others were interviewed. All were well but one, who died of uterine cancer 8 weeks later. Typical bronchial carcinoid is concluded to be of low-grade malignancy and suitable for limited pulmonary resection.

The clinical and histopathological characteristics of seven cases of Moderately Differentiated Neuroendocrine Carcinomas (MDNEC) and two cases of Poorly Differentiated Neuroendocrine Carcinomas (PDNEC) have been reviewed. The tumours arose in the supraglottis of predominantly elderly men. Two cases had raised levels of urinary 5-hydroxy-indole-acetic acid at presentation but no case developed the carcinoid syndrome. PDNEC were histologically identical to the oat cell type carcinoma of the bronchus and were associated with an extremely aggressive clinical course with both patients dying of widespread metastases within one month of registration. MDNEC also metastasized frequently with four of seven cases dying with widespread disease. The tumours have previously been reported as not being radiosensitive; however three cases remain free of disease following biopsy and radiotherapy alone. The place of radiotherapy in the management of these tumours is discussed.

The authors report their experience with resection of small bowel carcinoid tumors associated with diffuse hepatic metastases. Nine patients were operated during the last ten years. A carcinoid syndrome was present biologically in every case and clinically in 8 cases. The tumor was removed in every case, either by right hemicolectomy (n = 6), or by small bowel resection (n = 3). Postoperative mortality and morbidity were nil. Adjuvant therapy included hepatic chemo-embolization and long-term therapy by a long-acting somatostatin analog. Five patients died during the period of follow-up and 4 patients were alive at the end of the study. Resection of small bowel carcinoid tumor is indicated even when the liver is involved by diffuse metastases to prevent the risk of small bowel occlusion, and to promote hepatic chemoembolization as subsequent therapy against the carcinoid syndrome and metastatic spread. Moreover, the procedure can participate in the selection of cases for orthotopic liver transplantation, when conservative therapy fails to control the carcinoid syndrome.

The therapeutic principles in the management of endocrine gastroenteropancreatic (GEP) tumours include surgical extirpation of the primary tumour in the absence of metastases and medical control of symptoms in the preoperative phase. In the presence of metastases only palliative procedures are available. Tumour growth might be controlled by surgical procedures as debulking of tumour masses, medically by chemotherapy and more recently by new developments as a long-acting somatostatin analogue (SMS 201-995) and alpha-interferon. Their efficacy is currently evaluated in prospective studies. In contrast to inhibition of growth symptoms derived from excessive hormone production by GEP tumours can be well controlled. SMS 201-995 effectively prevents or at least improves flush and diarrhoea in the carcinoid syndrome, disabling diarrhoea in the Verner-Morrison syndrome and migratory erythema in the glucagonoma syndrome. SMS acts by inhibition of hormone release from the tumour and by a direct mechanism at the site of the target cell via SMS receptors present on tumour and target cells. For control of acid hypersecretion in gastrinoma patients omeprazole is superior to all former and present alternatives and replaced total gastrectomy completely. A similarly effective drug to prevent hypoglycaemia due to uncontrolled insulin release from insulinomas is not available since neither SMS nor diazoxide are effective in every insulinoma patient.

Seventy-five patients with advanced abdominal carcinoid tumors (65 midgut, 10 others) have been examined retrospectively to evaluate the role of surgical treatment as a principle, irrespective of stage of disease. Eighteen of 52 patients (35%) exhibited the carcinoid syndrome. Two or more primaries were found in 39% of patients with midgut lesion, 81% of these patients had regional metastases, 5% of these patients had distant lymph node metastases, and 74% of the patients had liver secondaries. All patients underwent operation, an additional 34% of the patients had a further reoperation, 9% of the patients had a second reoperation, 3% of the patients had a third reoperation, and one patient (2%) had a fourth reoperation. Intraoperative debulking (liver excluded) was performed in 33% of the patients, and 48% of the patients had treatment (resection, hepatic artery ligation, embolization) directed at the liver. The postoperative mortality rate was 2% after the primary operation for midgut lesions. The median survival for midgut tumors was 92 months, compared to 40 months for other lesions (not significant). A significantly higher survival rate was revealed for those patients with midgut lesion who were undergoing intraabdominal debulking procedures (liver excluded); median survival was 139 months versus 69 months without debulking. For those patients with liver metastases, median survival after intervention was 216 months and 48 months without such treatment (p less than 0.001). It is concluded that resection of intraabdominal carcinoid tumor masses can be performed in a high proportion of patients. Despite the retrospective, uncontrolled nature of this study, the difference in survival probabilities in favor of aggressive surgical therapy is so marked that it is not unreasonable to conclude that surgery has played a role in prolonging life in these patients.

A primary carcinoid tumour of the testicle without carcinoid syndrome was recorded from a patient aged 48 years. The tumour was made up of solid and acinar structures which exhibited strongly pronounced argyrophilia. Teratogenic structures were not established. Neuron-specific enolase (NSE) and chromogranin were immunohistologically recorded from tumour cells. The carcinoid had not spread metastases. Semi-castration was chosen as therapeutic approach. Orchidectomy was not followed by complications.

In patients with midgut carcinoid tumors a curative, radical tumor removal should be attempted when possible. As these tumors are generally malignant, irrespective of size, the radical surgery implies that intestinal resection for excision of a primary tumor should be combined with an extended mesenteric resection. When the patients present with the carcinoid syndrome the disease is, with few exceptions, too advanced for curative surgery. However, surgery often has to be performed also in patients with the advanced carcinoids. Patients with more extensive disease may thus benefit from surgical debulking of large mesenteric or hepatic metastases. Moreover, when the patients present with abdominal symptoms it is important to exclude a threatening major abdominal complication, such as intestinal obstruction or ischemia. As these complications may cause malnutrition and deterioration, it is important to treat them properly, sometimes by repeated surgery.

Serotonin-producing pancreatic endocrine tumours are rare neoplasms which in most cases exhibit malignant biological behaviour. These tumours, in the majority of the well-documented cases, are composed of argyrophil- and argentaffin-positive cells which contain large pleomorphic neurosecretory granules. In contrast, argyrophilic non-argentaffin pancreatic endocrine tumours with tumour cells containing round neurosecretory granules are exceptional. In this study we describe such a tumour not associated with clinical evidence of carcinoid syndrome in a 60-year-old woman. Histological examination revealed tumour extension in pancreatic lymphatic vessels and veins but no evidence of locoregional or distant metastases. Ten months after surgery the patient showed no recurrence of the disease. Immunohistochemistry revealed cytoplasmic serotonin production in the tumour cells which were negative for anti-gastrin, insulin, glucagon, somatostatin, pancreatic polypeptide (PP), vasoactive intestinal peptide (VIP) and ACTH. This study emphasizes the usefulness of combined ultrastructural and immunohistochemical investigations in order to identify and characterize the rare pancreatic endocrine tumours with serotonin production.
