A patient with carcinoid syndrome on long-term antiserotonin therapy with parachlorophenylalanine, experienced a flushing attack with hypotension during the prophylactic administration of aprotonin prior to the induction of anaesthesia. When she was subsequently prepared with a long-acting somatostatin analogue, octreotide (Sandostatin, Sandoz SMS 201-995), plasma levels of tumour-released hormones were reduced and anaesthesia for resection of hepatic metastases was uneventful. The advantages of an anaesthetic approach based on inhibition of carcinoid tumour activity, rather than antagonism of released hormones, are discussed.

A 47-year-old man with multiple endocrine neoplasia (MEN) type 2a syndrome in whom metaiodobenzylguanidine (MIBG) concentrated in lesions from metastatic medullary carcinoma of the thyroid is reported. A somatostatin analogue (Sandostatin SMS 201-995) alleviated the symptoms of flushing and diarrhea associated with the elevated calcitonin levels but it did not alter either the course of the disease or the MIBG images. A review of the literature is presented of the noncatecholamine secreting tumors associated with MIBG uptake. Similarities between this case and metastatic carcinoid syndrome are discussed.

Carcinoid syndrome produces flushing, bronchoconstriction and gastrointestinal hypermotility secondary to serotonin, histamine, bradykinin and prostaglandin release. A variety of drugs, foods and anaesthetic agents may provoke this syndrome. Under anaesthesia, the flushing produced may be associated with acute hypotension and cardiovascular collapse; this phenomenon is called a carcinoid crisis. Recently, somatostatin analogue has been used successfully to treat intraoperative carcinoid crisis. In this report, we present a 66-year-old lady with carcinoid syndrome who was pre-treated with 50 micrograms somatostatin analogue IV and IM prior to surgical manipulation. The anaesthetic course was relatively uneventful and the patient did well postoperatively.

Intractable diarrhoea and flushing due to the malignant carcinoid syndrome is seldom relieved by conservative medical treatment. Octreotide (Sandostatin; Sandoz) is a long-acting analogue of somatostatin and a powerful inhibitor of endogenous peptide release. A patient with severe diarrhoea and flushing due to the malignant carcinoid syndrome, in whom symptomatic control with octreotide was achieved, is described, and the value of octreotide treatment in the malignant carcinoid syndrome is discussed.

Carcinoid tumors are the most frequent gut neuroendocrine tumors accounting for more than 50% of all tumors of the gastroenteropancreatic (GEP) axis. These tumors appear to derive from a stem cell line capable of differentiating into a variety of malignant cells that secrete many different peptides and amines. The symptoms of carcinoid tumors are often non-specific, vague abdominal pain that may precede the diagnosis by a median of 9 years. Carcinoid syndrome occurs in less than 10% of patients. We evaluated the effects of SMS 201-995 in 14 such patients, 12 with diarrhea, 8 with flushing, 3 with wheezing, one with tricuspid valve incompetence, 6 with facial telangiectasia, 3 with a pellagra type dermatosis and one with myopathy. Diarrhea was abolished or significantly reduced in 83%, flushing in 100%, wheezing in 100%, and myopathy improved in the one patient. Blood serotonin was resistant to change, urine 5HIAA fell in 75%, and most gut neuropeptide hormones apart from somatostatin were suppressed. Tumor growth appeared to be slowed in 2/3 of cases treated for up to 4 years. The analog of somatostatin appears to be a useful addition to the therapeutic armamentarium for carcinoid tumors and the symptom complex.

Diagnostic approaches, clinical characteristics, and (briefly) therapy of the carcinoid syndrome and disorders of systemic mast cell activation are outlined. Mediators responsible for the humoral manifestations of the two syndromes are discussed. Because some of the clinical features of both disorders are similar (in particular, flushing), specific attention is given to the clinical differentiation of these disorders.

The exact etiology of carcinoid flushing remains unknown, but the symptoms are probably mediated through release of one or several humoral substances. Flushing seen in fore-gut carcinoids (gastric carcinoids) has been ascribed to excessive histamine release, whereas flushing seen in mid-gut carcinoids (ileal carcinoids) tentatively has been ascribed to excessive release of serotonin, bradykinin, substance P, substance K or eledoisin. In this study plasma histamine was measured in 8 patients with mid-gut carcinoids and carcinoid syndrome using an enzymatic isotopic method in order to evaluate histamine as the vasoactive agent in patients with ileal carcinoid tumours and carcinoid syndrome. All patients had raised plasma histamine values. In patients with mid-gut carcinoids histamine may be one of the substances mediating flushing.

A case of carcinoid syndrome is presented. Pulmonary adenosquamous carcinoma with hepatic metastasis was found in a 60-year-old Japanese male who was complaining of fever, cough and haemosputum. After the treatment with 5-fluorouracil (5-FU) over 2 years, he was diagnosed as carcinoid syndrome on the appearance of facial flushing, face edema and watery diarrhea accompanied by high levels of 5-hydroxyindole acetic acid (5-HIAA) in blood and urine. Prednisolone, which was initially effective, was replaced by SMS201-995 due to the considerable dose increase of the former because its effect became insufficient during the course of the treatment. Clinical symptoms were improved by SMS201-995 and blood 5-HIAA level decreased gradually but markedly. Thus better results were obtained by SMS201-995 compared with prednisolone. These results imply that SMS201-995 is appreciated as an effective drug for treatment of carcinoid syndrome.

Bradykinin concentrations in peripheral venous blood were measured in seven patients with carcinoid syndrome. The diagnosis was based on typical symptoms and raised urinary excretion of 5-hydroxy-3-indole acetic acid; the carcinoid tumour was verified histologically. Two patients were flushing constantly and the other patients had flushing attacks two to 10 times daily. Several blood samples were taken at weekly intervals from six of seven patients. During 30 sampling procedures the patients were flushing during sampling in 12 instances. Bradykinin was measured by a sensitive solid phase radioimmunoassay technique. Blood bradykinin concentration was normal in all patients. Bradykinin is unlikely to be the vasoactive mediator of flushing.

Seven patients, four women and three men, with a median age of 64 years (range, 53-74 years) were randomized to treatment with either ketanserin, 40-160 mg daily, or placebo. The study included 13 treatment periods with ketanserin and 13 with placebo. All patients had typical symptoms, with flushing as their main complaint. The diagnosis had been verified histologically. All had elevated excretion of 5-hydroxy-3-indoleacetic acid in urine. During the trial ketanserin reduced the number of flushing attacks in five patients (p less than 0.05). Diarrhoea was reduced in two patients. No side effects were observed. Ketanserin seems valuable for the symptomatic relief in the carcinoid syndrome.
