Fifteen patients with advanced gastric cancer were treated with the combination of Ftorafur, Adriamycin and mitomycin-C (FAM II). Three patients showed partial responses, in five the disease remained stable for at least 3 months and seven showed progression while on treatment. All responding patients showed survival in excess of 12 months. Hematologic toxicity was of only moderate severity. Median white count nadir was 3500 cells/mm3 and median platelet nadir was 187,000 cells/mm3. Four patients had white count nadirs from 2000--2500 cells/mm3 and three had nadirs from 500--1500 cells/mm3; also there were four with platelet nadirs less than 100,000/mm3. However, no drug-related infections occurred and no platelet transfusions were required. The major non-hematologic toxicities of the regimen were nausea, vomiting, dizziness, vertigo, and rhinorrhea. These toxicities were limiting and resulted in termination of the trial because of poor patient acceptance and the failure of the combination to exhibit a therapeutic advantage over the similar combination (FAM) that employed weekly 5-fluorouracil in place of Ftorafur.

A 67-year-old man was admitted in October 1987 with complaints of nausea, headache, dizziness and speech disturbance. Hematological examination showed pancytopenia. Bone marrow aspiration failed with a dry tap. A month later, the second aspiration showed hypocellular marrow containing 18.2% of lymphoma cells. Physical examination showed splenomegaly and lymph node swelling. Polyclonal hypergammaglobulinemia was not observed. A lymph node biopsy exhibited typical histology of immunoblastic lymphadenopathy (IBL)-like T cell lymphoma. Surface marker CD3 and CD4 positive cells were dominant. The patient complained of epigastric pain and occult blood was positive in stool. Gastrofiberscopic examination disclosed well differentiated adenocarcinoma in situ located on a polyp, and polypectomy was performed. Lymphoma was treated with cyclophosphamide, doxorubicin, vinblastine and prednisolone. Splenomegaly and lymph node swelling were reduced in size but the effect was temporary. Thereafter the patient has been treated with cyclophosphamide, doxorubicin, vindesine, prednisolone and etoposide every 3 weeks. This is our first case report of IBL-like T cell lymphoma associated with early gastric cancer.

A case of synchronous multiple primary neoplasms, an intracranial malignant lymphoma and a gastric carcinoma, is presented. A 63-year-old man was admitted to our hospital with complaints of dizziness and a floating sensation on gait. A CT scan after admission, revealed a well-defined, nodular high density area in the left frontal lobe, which was markedly enhanced by the contrast medium. In order to rule out a metastatic brain tumor, examinations were performed as a consequence, and, the gastric carcinoma was found. A partial removal of the brain tumor and a gastrectomy were performed in two stages. Pathologically, the diagnosis of the brain tumor indicated a malignant lymphoma of large cell type, and that of the gastric carcinoma was an adenocarcinoma. The patient received postoperative irradiation and chemotherapy and was discharged in a good condition. He died of pneumonia 21 months after the operation. Necropsy revealed a marked atrophy of the brain without recurrence of the malignant lymphoma and no recurrence of a gastric cancer.

Eighty consecutive patients with endoscopically proven gastric ulcer were randomly assigned to treatment with sucralfate, 1 g four times daily, or cimetidine, 200 mg three times daily and 400 mg at night. The patients were endoscoped after four and eight weeks by an examiner who was unaware of the treatment in use. Of the 40 patients assigned to each treatment group, 2 in the sucralfate and 4 in the cimetidine group were withdrawn due to the finding of gastric cancer in the biopsies. Two patients in the sucralfate and 3 patients in the cimetidine group interrupted treatment. Complete ulcer healing was found after four weeks of treatment in 17 of the 36 patients (47%) in the sucralfate and in 16 of the 33 patients (48%) in the cimetidine group. The cumulative healing rate after 8 weeks of treatment was 80% in the sucralfate group and 73% in the cimetidine group. There were no serious side effects, but it was necessary to discontinue treatment with cimetidine in two subjects because of rash in one and dizziness in the other. The results suggest that sucralfate is an effective and safe drug for the treatment of gastric ulcer and that its efficacy is equivalent to that of cimetidine.

A Phase II study of a new fluorinated pyrimidine (TAC-278) was performed in 14 institutions from May 1980 to April 1981. 400-1200 mg of TAC-278 was orally administered in 2 to 4 divided doses every day for more than 4 weeks. Selection of patients and evaluation of clinical response were done according to the criteria for "Evaluation of Clinical Effects of Chemotherapy on Solid Tumors" by Koyama and Saito. A total of 188 patients were entered in the study and 96 of them were evaluable. Partial responses were observed in 9.4% (9/96) of the evaluated cases. Stomach cancer and colorectal cancer showed partial responses in 10.8% (4/37) and 20% (5/25), respectively. As for side effects, slight gastrointestinal symptoms (loss of appetite, nausea and vomiting etc.) were found in 24% and CNS-symptoms such as dizziness and disorientation were observed in approximately 8% of the patients.

During the past 2 decades, great advances have been made in the treatment of ulcer disease. This has involved the development of new drugs that are not only well tolerated, but are relatively inexpensive. The lack of significant adverse effects has revealed a degree of tolerability that, to write a review of the adverse effects, poses a difficult task. Most of the adverse effects are related to an excessive reaction to the relevant pharmacological characteristic that mediates the therapeutic response. The drug dosage can be reduced, freeing the patient of the adverse reaction, but leaving behind a background activity adequate to produce a therapeutically beneficial effect. The adverse effects of H2-antagonists fall into 2 groups. Firstly, there are poorly defined symptoms that have a prevalence similar to that in the community; these include headache, giddiness, dizziness, fatigue, constipation and diarrhoea. Secondly, they may delay the metabolism of drugs metabolised by the the cytochrome P450 system, and rarely be androgenic. Many antacids and the site-protective agent sucralfate contain aluminium, which can be absorbed, producing elevation of serum aluminium levels. In view of the possible association of aluminium with Alzheimer's disease, anxiety has arisen as to whether aluminium from these sources may, in those on prolonged treatment, cause Alzheimer's disease. However, the evidence so far indicates that aluminium is not a risk factor for Alzheimer's disease. The association of gastric cancer with achlorhydria has led to the fear that long term use of potent acid inhibitors may cause cancer. This fear has been accentuated by the observation that some rats, given omeprazole over their lifetime, developed carcinoid tumours of the stomach. However, enthusiastic research, both clinical and epidemiological, indicates that drug-induced achlorhydria is unlikely to be a problem in humans. Site protective agents have a role in certain conditions such as pregnancy where the systemic effect of a drug may produce adverse effects.

A 68-year-old man with disturbed consciousness had repeatedly developed light-headedness and dizziness since the summer of 1996 and was admitted to a hospital for detailed examinations on October 8, 1996. On admission, he weighed 49 kg and showed subclinical hypothyroidism with low T3 syndrome. The adrenal function and serum electrolytes were normal. Since the stool samples were positive for occult blood, gastroscopy was performed. Examination of the biopsy specimens demonstrated gastric cancer. On October 21, blood examination showed hyponatremia (127 mEq/l). On October 22, marked disturbance of consciousness developed. On October 24, the serum Na level further decreased to 116 mEq/l. On November 8, he was referred to our hospital. On admission, his skin and tongue showed marked dehydration, and severe disturbance of consciousness and neck stiffness were observed. The central venous pressure was 4 cmH2O. In the cerebrospinal fluid, atypical cells were observed, and a diagnosis of meningeal carcinomatosis was made. Syndrome of inappropriate secretion of antidiuretic hormone (SIADH) was excluded because of marked dehydration, a normal blood ADH level, and because plasma osmotic pressure was greater than urinary osmotic pressure. Considering the possibility of cerebral salt wasting syndrome (CSWS) or hypoadrenocorticism, Na supplementation and drip infusion of prednisolone (20 mg/day) were performed. The serum Na has normalized (140.1 mEq/l), and his consciousness improved. He died of aggravation of the general condition on December 16. Pathological examination demonstrated a small metastatic lesion in the infundibular part of the pituitary gland and a small metastatic lesion in the parenchyma of the bilateral adrenal glands. However, since neither hypotension nor hypoglycemia was observed before treatment, and the blood cortisol level and the serum K level were normal, hypoadrenocorticism was excluded. Hypoaldosteronism was also excluded because of a normal serum K level. CSWS has been reported to be caused by head trauma, subarachnoid hemorrhage, or trans-sphenoidal pituitary operation. This patient is a rare case of CSWS developed in the presence of meningeal carcinomatosis accompanied by a small pituitary metastatic lesion from gastric cancer. The aged with decreased ability to retain water and sodium in the body are more susceptible to CSWS than the young. In the aged with central hyponatremia, the possibility of CSWS should be considered, and early diagnosis and treatment are necessary.

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.

A 70-year-old man presented with dizziness, headache and hearing loss. He was admitted to our hospital because of increasing unsteadiness of gait. Magnetic resonance imaging of the brain revealed meningeal thickening with enhancement. The lumbar puncture revealed high opening pressure. The cerebrospinal fluid showed pleocytosis, high carcinoembryonic antigen (CEA) concentration, and presence of neoplastic cells, leading to the diagnosis of leptomeningeal carcinomatosis. Systemic investigation for primary neoplasm identified a Bormman type 3 gastric cancer (papillary adenocarcinoma with micropapillary pattern). Except for the meninges, no metastatic lesions could be detected. A ventriculoperitoneal shunt (Codman Hakim Programmable Valve) was placed for management of intracranial hypertension and intrathecal chemotheray. He was started on oral S-1 (TS-1) combined with intrathecal methotrexate injection using the VP shunt reservoir. In two weeks, headache and hearing loss completely disappeared and gait disturbances started to improve. CSF findings also improved remarkably with disappearance of neoplastic cells and almost normalization of CEA. For the next five months, he was well on oral S-1 and monthly intrathecal chemotherapy, being able to walk using a walker and to stay at home. He subsequently developed posterior cortical symptoms such as prosopagnosia and cortical blindness and gradually lapsed into coma. He died from pneumonia one year after the onset of neurological symptoms. At autopsy, primary gastric cancer was found but much reduced in size. No peritoneal metastasis could be found. In the brain, leptomeningeal carcinomatosis involved the occipital lobes, the base of the temporal lobe, and the cerebellum. We suggest that intrathecal chemotherapy using ventriculoperitoneal shunt with programmable valve system could be an effective method for the treatment of meningeal carcinomatosis.
