We describe the case of a patient suffering from relapsing abdominal pain and vomiting over 4 years, in whom various radiological and endoscopic examinations remained normal. CT scan and MRI eventually showed a mesenteric mass corresponding to metastasis of an ileal carcinoid; this tumor was diagnosed only at laparotomy as well as his mesenteric and hepatic metastases. The different localization and clinical manifestations of carcinoid tumours as well as the difficulties of radiological diagnosis of tumours of the small bowel are mentioned; the diagnostic value of sonography. CT-scan and MRI in the diagnosis of hepatic metastasis is discussed.

Severe hypercalcemia is a medical emergency requiring urgent treatment. It most commonly is caused by malignant tumors, as in the case study, but can also be caused by advanced hyperparathyroidism or high serum levels of vitamin D. The patient described in the case study shows clinical evidence of volume contraction due to hypercalcemia-related anorexia and vomiting. His elevated serum concentrations of urea nitrogen and creatinine reflect intravascular volume depletion and hypercalcemia-induced reduction of renal perfusion. He is also likely to have irreversible renal damage as a result of nephrocalcinosis. His central nervous system depression is most likely a result of hypercalcemia, but other central nervous system disorders such as cerebral metastases should be considered. Appropriate treatment would include intravenous fluids to correct volume depletion, dilute extracellular fluid calcium, and promote renal calcium excretion. Before waiting for the effects of volume expansion, the first dose of an inhibitor of bone resorption should be given. The agent of choice now (this may change when second-generation bisphosphonates become available) is plicamycin. Etidronate is a reasonable second choice. Because both drugs require at least 48 hours before their hypocalcemic action is manifest, calcitonin could be used to accelerate the rate of decline of the serum calcium. As the patient becomes more alert, weight-bearing and ambulation should be encouraged. With this combination of therapeutic modalities, this patient's serum calcium level should be corrected within 3 to 5 days. Intermittent injections of mithramycin or etidronate could be given on an outpatient basis approximately once a week in order to maintain the serum calcium within the normal range. One of the most important aspects of treatment in hypercalcemic patients is eradication of the underlying disease, which usually calls for specific antitumor therapy, including chemotherapy, radiation therapy, or surgery. Most of the agents currently available for the correction of hypercalcemia have cumulative toxicities or are only transiently effective and, therefore, their use should be considered a temporizing measure until specific treatment directed at the primary disease takes effect.

Sixteen patients with metastatic melanoma were treated with N-methylformamide (NMF), a polar-planar compound with in vitro cytotoxic and differentiating properties. Sixteen patients were evaluable for toxicity and 14 for response. The initial four patients received an intravenous bolus of NMF 800 mg/m2 daily for 5 consecutive days every 28 days. Because of excessive gastrointestinal toxicity, the dose was reduced to 700 mg/m2/day for the subsequent 12 patients. Two patients had immediate adverse effects from NMF; one had a grand mal seizure and the other developed severe abdominal pain. Nausea, vomiting and abdominal pain were dose-limiting. Transient elevation of liver function tests occurred in all patients. Myelosuppression was not observed. There were no objective responses among 14 evaluable patients (95% confidence limits 0-20%). One patient with pulmonary metastases had a minor response lasting 13 months. Median time to progression of disease was one month. NMF in these doses and schedule lacks clinical efficacy in the treatment of metastatic melanoma.

Lonidamine revealed synergistic effects with anthracyclines and alkylating agents in experimental investigations. It differs from conventional cytostatics by acting on the cell energy metabolism and also lacks their typical side effects; therefore it may be valuable to be combined with established chemotherapeutic regimens. Because in unselected patients the results of randomized studies may be influenced by differences in type and combination of prognostic factors, we defined strict entry criteria: no previous systemic palliative treatment, disease-free interval less than or equal to 2 years, measurable visceral metastases, number of tumor sites less than or equal to 2, no brain or bone metastases, World Health Organization performance status less than or equal to 2, age less than or equal to 55. In an ongoing rate, remission duration, time to treatment failure, and survival time in patients treated with vindesin 3 mg/m2 plus epirubicin 100 mg/m2 plus cyclophosphamide 600 mg/m2 (day 1, intravenous, repeated every 3 weeks) +/- lonidamine 600 mg/day orally. Eight of 12 patients achieved an objective remission (complete response 4, partial response 4), 1 patients had a stable disease, 2 patients experienced tumor progression; 1 patient is not yet evaluable for response. In spite of the intensity of the therapy no treatment interval prolongation was necessary. Main toxicities were myelosuppression, nausea, emesis, alopecia, and in patients treated with lonidamine, mild myalgia. The addition of lonidamine to polychemotherapy did not affect myelosuppression. Differences in remission rates or remission duration due to lonidamine could not yet be demonstrated.

Two new cases of papillary and cystic neoplasm of the pancreas are reported. One patient was a 20-year-old woman with massive unresectable liver metastases, and the other was a 15-year-old boy. To study the natural history and malignant potential of this tumor, the English literature was reviewed to obtain an additional 56 cases. Clinical characteristics include pain and a mass in most patients, although many are found incidentally. Jaundice, hemoperitoneum, nausea, and vomiting are unusual findings. Most patients are treated by wide resection with good results. These tumors appear to be indolent. However, 16% of patients had major organ or blood vessel invasion, and 7% had liver metastases at some time during the course of their disease, illustrating the malignant nature of this tumor. Long-term follow-up is necessary to evaluate the efficacy of treatment, especially in the case of locally advanced and metastatic disease.

Fifty patients affected by histologically confirmed gastrointestinal tract cancer (GTC) were treated with oral tegafur (TG) 1,000 mg m-2 p.o. on days 1-14 repeated after a 14 day interval. Out of 42 evaluable patients seven patients had a partial response (PR. 17%) with a median duration of 20.5 weeks, three had a minimal response (7%) with a median duration of 23.7 weeks, nine showed a stabilisation which lasted a median of 31.3 weeks, and 23 progressed (55%). No response was obtained in patients affected by carcinoma of the pancreas and the hepatobiliary system. All PRs were achieved in patients with metastatic disease to the liver. No response was seen in patients with bone, lung or nodal metastasis. Three PRs were obtained in patients resistant to 5-fluorouracil. The difference in survival between patients who achieved PR and those who had a stabilisation was not statistically significant. On the other hand the survival of patients with PR was significantly longer than that of patients who progressed. Oral TG was well tolerated by most patients. WHO grade 1-2 gastrointestinal and neurological toxicities were seen respectively in 36% and 25% of cases. Five patients had grade 3 nausea/vomiting and one had grade 3 diarrhoea. Our data suggest that oral TG is effective in the treatment of stomach and colorectal cancers.

Thirty-seven patients with retinoblastoma were evaluated prospectively by clinical examination, lumbar puncture, and CT. Eight (22%) of the 37 were found to have meningeal dissemination. The tumor was bilateral in three patients. Two cases showed no CT signs of local recurrence. Headache, nausea/vomiting, and restlessness were the most common symptoms. CT scans in these patients showed diffuse meningeal contrast enhancement, nodular masses, ependymal-subependymal enhancement, and ventricular dilatation. Our series of eight patients with meningeal spread illustrates a considerable range of dissemination patterns referable to retinoblastoma. One case illustrated the CT finding of multiple epidural metastases.

From May 1986 until July 1987, oral morphine hydrochloride in water solution was used in terminal patients, under a strict protocol of administration, and complying with the basic principles of Palliative Care. A retrospective study was carried out on the 40 patients who had received the drug for more than three consecutive days. As shown in Table 1, the average age of the treated patients was 70 years. The ambulatory patients represented 27.5% of the sample. The average initial dose was 60 mg, and the average maintenance dose was 120 mg. The median treatment time was 45 days. "Good" results were achieved in 85% of the patients, and "fairly good" in the remainder ("good" results were defined as "satisfactory symptom control, good life quality"--in this group there were some patients who obtained total suppression of the symptoms and optimal life-quality, i.e. "excellent" results; "bad" results were defined as "total absence of therapeutic effect"; and "fairly good" results, the intermediate cases). The more frequently treated symptoms were: 67.5%, pain due to tumor mass; and 20%, pain due to nerve compression-invasion, bone pain, and dyspnoea due to pulmonary metastases or primary lung cancer: total symptoms was more than a hundred per cent, because a number of patients had more than one symptom. Whenever necessary, adjuvant drugs were employed. Side effects were seen in 37% of the patients (specially nausea, vomiting, constipation, and somnolence for more than four days).(ABSTRACT TRUNCATED AT 250 WORDS)

One hundred and sixty-six patients with advanced breast cancer previously not treated with chemotherapy for metastatic disease were randomly allocated to 20 mg Adriamycin i.v. weekly (Awkly) as bolus injection or 50 mg 4-epidoxorubicin biweekly over a 3-h infusion time (EPIbiwkly). Of the 149 patients evaluable for response, the response rate was 36% for Awkly vs. 22% for EPIbiwkly (P = 0.10). There was no difference in response duration or survival. The main difference between the two regimens was in toxicity. Seventy per cent of Awkly patients virtually had no side-effects vs. 15% in the EPIbiwkly group. Significant differences in favour of Awkly were observed both for nausea/vomiting and alopecia.

The purpose of the study was to investigate the antitumour activity and toxicity of high dose (120 mg m-2) single agent epirubicin therapy in untreated extensive small cell lung cancer patients. Out of 80 patients entered, 71 were evaluable for both antitumour activity and toxicity, 4 only for toxicity and 5 were lost for follow-up. The drug possessed a high antitumour activity, the overall response rate was 47.9% (34/71) with 4 complete remissions (CR) and 30 partial remissions (PR). The median remission duration was 3.5 months. Particular drug activity was observed in the primary tumours, lymph nodes and pleural metastases. Toxicity (leukopenia, anaemia, vomiting, reversible rhythmic cardiac disorder, stomatitis) was mild, alopecia was registered less than in adriamycin medication. One fatal congestive heart failure occurred. The actual mean survival time calculated on the basis of the data gained from 64 patients was 7.0 months (range 2-22). The high antitumour activity and no increase in toxicity justify the incorporation of high dose epirubicin into combination therapy.
