Forty-six patients with progressive metastatic disease following initial response to tamoxifen therapy were treated with aminoglutethimide. Three patients (6%) achieved complete remission, 15 patients (33%) had partial response, and eight patients (17%) had stable disease. Twenty patients (44%) had progressive disease. The most common side effects were transient skin rash, lethargy, or dizziness. In four patients (7%), treatment was discontinued because of undesirable side effects within the first 2 weeks of the study. These data show that aminoglutethimide is an effective agent following tamoxifen therapy.

Two female patients with an adenocarcinoma of the colon (Duke stages B and C) underwent colectomy followed by adjuvant chemotherapy combining 5 fluorouracil (5 FU) and levamisole. Secondary neurological manifestations occurred in both patients including vertigo, nausea and vomiting, dizziness with loss of balance, slow ideation, impaired memory, headache and, on one case, central origin facial paralysis. Symptoms appeared between the 11th and 34th week of treatment. The patients had received 9 to 30 g 5 FU and 2.7 to 7.6 g levamisole. CT scan and/or MRI first suggested cerebral metastases then demyelinisation. The clinical signs disappeared spontaneously in less than one month. The brain images were unchanged. The 5 FU/levamisole combination was undoubtedly responsible for the neurological manifestations. Levamisole may have potentialized the effect of 5 FU leading to demyelinisation. Whether chemotherapy should be stopped or not is debated.

Neuroendocrine pancreatic tumors are neoplasms derived from APUD cells, characterized by hyperincretion of several peptides of hormonal activity. The incidence of these tumor is low. They are usually classified according to the predominant secreted peptide: gastrinoma, insulinoma, VIPoma, glucagonoma. Insulinoma is the most frequent endocrine pancreatic tumor, characterized by a peculiar clinical picture due to insulin action. This neoplasm is prevalently benign (90%), and may cause symptoms due to hypo-glycemia such as epilepsy, asthenia, deep coma, dizziness, hunger and epigastric pain. Surgery still constitutes the principal therapy for insulinoma treatment, but an accurate tumor identification is necessary. Selective arteriography of the pancreas and new diagnostic investigations as intraoperative US, selective sampling of pancreatic veins with insulin Quick-RIA, aid the diagnosis and more precise localization of the tumor. When surgical therapy is not practicable, for diffuse metastases, octreotide has an inhibitory effect upon hormone release, and may be combined with chemotherapy for controlling clinical symptoms. We review the clinical records of 2 patients from our Institute, who had hyper-insulinism due to benign insulinomas of the tail of the pancreas. Surgical treatment was performed with enucleation of the neoplasms.

Clinicopathological and immunohistochemical studies were performed in a patient with paraneoplastic limbic encephalitis, myelitis, sensory neuropathy and cerebellar degeneration secondary to small cell lung cancer. A 67-year-old male smoker developed orthostatic dizziness 6 months prior to admission. Over the following months, his wife noticed that he became forgetful and confused. Over the next three weeks, he became unable to sit or stand unaided and admitted to our service. On admission, he was lethargic and disoriented in time and place. Neurological examination revealed marked limb weakness with distal dominant muscle atrophy. A chest radiograph demonstrated a mass in the right middle lobe and a bronchial biopsy revealed a small cell carcinoma. CT scan and MRI of the brain revealed abnormalities in the bilateral medial temporal lobes and putamen. He was treated with anti-cancer chemotherapy, but died of respiratory failure after 13 months illness. Postmortem examination showed a mass in the right middle lobe of the lung. No tumor metastases were noted in the nervous tissue. Microscopical examinations of the nervous system revealed neuronal loss, astrogliosis and perivascular and parenchymatous lymphocytic infiltration in the hippocampus, subiculum, amygdala, putamen, medulla oblongata, spinal cord and dorsal root ganglia. Loss of Purkinje cells was also seen in the cerebellum without lymphocytic infiltration. Immunohistochemical analysis of the patient's serum and CSF by the use of adult rat brain revealed immunoreactivity at the hippocampal pyramidal neurons CA3 and CA4. At the higher dilution, neuronal nuclei were specifically stained.(ABSTRACT TRUNCATED AT 250 WORDS)

From Jan. 1993 to Sept. 1995 23 patients suffering from brain metastases from renal cell carcinoma were treated with the Leksell Gamma Knife at the University of Vienna. At the time of diagnosis 13 patients had single and 10 patients presented with multiple metastatic lesions with a total of 44 metastases in MRI scans. Median tumour volume was 5500 cmm (range 100-24000 cmm). Predominant neurological symptoms and signs were different forms of hemiparesis, focal and generalized seizures, cognitive deficit, headache, dizziness, ataxia and CN XII paresis. Fourteen patients received Gamma Knife Radiosurgery (GKRS) with a median dose of 22 Gy (range 8-30 Gy) at the tumour margin. Nine patients underwent a combined treatment of a radiosurgical boost with a median dose of 18 Gy (range 10-22 Gy) at the tumour margin followed by Whole Brain Radiotherapy (total dose 30 Gy/2 weeks). In 20 patients tumour volume reduction up to 30% of the primary tumour volume was found after 4 weeks, evaluated on CT or MRI. A total remission was seen in 4 cases 3 months after GKRS. We achieved a local tumour control of 96%. Rapid neurological improvement after GKRS was seen in 17 patients. The median survival time was 11 months; the one-year actual survival in this unselected group was 48%. Five long term survivors were still alive, 18 patients had subsequently died, 15 of them of general tumour progression. GKRS induces a significant tumour remission accompanied by rapid neurological improvement and therefore provides the opportunity for extended high quality survival. Neither local tumour control was improved nor CNS relapse free survival was prolonged significantly by additional WBRT.

Stereotactic radiosurgery (SR) is being used with increasing frequency in the treatment of brain metastases. This study provides data from a clinical experience with radiosurgery in the treatment of cases with multiple metastases and identifies parameters that may be useful in the proper selection and therapy of these patients. From January 1993 to April 1997, 97 patients (43 women and 54 men; median age 58 years) suffering from multiple brain metastases (median 3; range 2-4) in MRI scans, received SR with the Gamma Knife. The median dose at the tumor margin was 20 Gy (range 17-30 Gy). Median tumor volume was 3900 cmm (range 100-10,000). Different forms of hemiparesis, focal and generalized seizures, cognitive deficit, headache, dizziness and ataxia had been the predominant neurological symptoms. Major histologies included lung carcinoma (44%), breast cancer (21%), renal cell carcinoma (10%), colorectal cancer (8%), and melanoma (7%). The median survival time was 6 months after SR. The actual one-year survival rate was 26%. In univariate and multivariate analysis, a higher Karnofsky performance rating and absence of extracranial metastases had a significantly positive effect on survival. Local tumor control was achieved in 94% of the patients. Complications included the onset of peritumoral edema (n = 5) and necrosis (n = 1). SR induces a significant tumor remission accompanied by neurological improvement and, therefore, provides the opportunity for prolonged high quality survival. We conclude that radiosurgical treatment of multiple brain metastases leads to an equivalent rate of survival when compared to the historic experience of patients treated with whole brain radiotherapy. Patients presenting initially with a higher Karnofsky performance rating and without extracranial metastases had a median survival time of nine months. Each such case should therefore be evaluated based on these factors to determine an optimal treatment regimen.

This phase II, multicentre, open-label, clinical trial evaluated antitumoral efficacy, tolerability and endocrine effects following 25 mg of treatment with oral exemestane given daily to postmenopausal women with metastatic breast cancer. Eligibility criteria included oestrogen and/or progesterone positivity or a prior response to hormonal therapy if receptor status was unknown; prior failure to tamoxifen therapy; and progressive disease. Patients were divided into three strata: patients who did not respond to tamoxifen or progressed after disease stabilisation (SD) for less than 6 months (stratum 1); patients who, after an initial response or SD lasting at least 6 months, experienced disease progression whilst on tamoxifen (stratum 2); patients with recurrent metastatic disease during or within 12 months of discontinuing adjuvant tamoxifen (stratum 3). Of the 137 patients who received exemestane, 4 experienced a complete response (CR) and 28 a partial response (PR), for an overall response rate of 23%. Another 33 patients had SD for > or = 24 weeks, resulting in an overall success rate of 47%. The median time to objective response was 16.1 weeks (95% confidence interval (CI) 9.9-24.1). The median response duration was 69.4 weeks, the median duration of overall success 59.1 weeks, the median time to progression (TTP) 25.1 weeks and the median time to treatment failure (TTF) 24 weeks. Response to previous hormonal therapy had little effect on the results, except that there was a trend toward a higher overall success rate in patients who did not respond to previous hormonal therapy. After 8 weeks of therapy, serum levels of oestradiol (E2), oestrone (E1) and oestrone sulphate (E1S) were suppressed to 15.2%, 9.7% and 10.7% of baseline, respectively. The most common adverse events of drug-related or indeterminate cause were hot flushes (14%), dizziness (9%), nausea (8%) and increased sweating (5%). Exemestane had a favourable effect on performance status and tumour-related signs and symptoms, both of which improved or stabilised in approximately 67% and 68% of patients respectively. Exemestane is a unique therapy that is highly active and well tolerated as a new treatment for women with metastatic breast cancer.

Gastric cancer is often diagnosed in middle-aged patients undergoing upper gastrointestinal endoscopy for abdominal complaints or constitutional symptoms, such as dyspepsia, vomiting or anorexia, weight loss, anemia, jaundice, and ascites. Sometimes, all of these symptoms may be absent, and gastric cancer is diagnosed after detection of metastases to target organs, such as the liver or lung. In a few rare cases, however, even these metastatic localizations may be absent, and clinical signs are only represented by atypical symptoms caused by neurologic metastatic involvement. We report an exceptionally rare case of gastric cancer in which the only presenting symptoms were headache and dizziness caused by a single cerebellar metastasis.

Primary choriocarcinoma of the stomach is an extremely rare and highly malignant tumor. A 68-year-old Japanese man was admitted to our department with symptoms of epigastric pain, abdominal fullness, and dizziness. Primary gastric choriocarcinoma with regional lymph node metastases was diagnosed preoperatively by the detection of elevated serum levels of a tumor marker, radiography, and immunohistochemical staining of biopsy specimens. The patient underwent total gastrectomy and jejunal reconstruction (Roux-en-Y method), followed by chemotherapy. Histological examination of the resected stomach revealed typical choriocarcinoma accompanied by common adenocarcinomatous elements. After postoperative chemotherapy the patient survived for 4 years and 6 months, and died with no evidence of recurrence of carcinoma. This is the first known patient with primary gastric choriocarcinoma to have survived for such a long period without recurrent elevation of the serum level of human chorionic gonadotropin (HCG), which was a useful marker when reevaluating the patient.

Primary tumors of the heart are rare, whereas cardiac metastases, most frequently from adenocarcinomas, occur in up to 20% of malignant tumors. We report about a 61-year-old female patient who was admitted with recurrent stress-induced dizziness, intermittent tachycardia and a fall due to a pre-syncope. Echocardiography showed a left atrial tumor with the typical features of a pediculated myxoma, leading to open heart surgery. However, histopathology revealed a 2.2 x 1.5 cm adenocarcinoma. The subsequent search for a primary tumor, including tumor markers and (18)F-FDG-PET, was unsuccessful, as was a second thorough diagnostic workup half a year later. The tumor was therefore classified as a primary cardiac adenocarcinoma.
