A series of 29 patients with early gastric cancer operated on in our department over a period of 10 years is presented; this figure represents 9.10% of total number of gastric cancers. The most common symptom was epigastric pain, present in 51.72% of cases. Diagnosis was established by endoscopy and biopsy in 96.5% patients. Treatment was subtotal gastrectomy in 28 cases; most lesions (24) were located in the distal third of the stomach. Lesion was intramucosal in 44.8% of cases; in 55.17% there was infiltration of the submucosal layer and only 13.8% of tumors presented lymph node metastases. Macroscopically the most common pattern of the lesions was the ulcerated type. All patients have been followed up at least 4 years; of them died: one of carcinoma of the bladder and three of chronic respiratory failure. There were no recurrences of the gastric lesion and the 5 years actuarial survival was 84.32%.

To our knowledge, esophageal carcinoma that is metastatic to the gastric cardia has rarely been described in the radiologic literature. We examined seven patients who had a solitary metastasis in the gastric cardia that had spread from esophageal carcinoma. Five of the gastric lesions were synchronous with the primary lesion, and two developed after the primary tumor had been detected. Radiographically, the gastric lesion appeared as a submucosal mass in five patients and appeared to simulate a primary gastric carcinoma in the other two patients. The metastases had probably disseminated through the submucosal lymphatic system. Because the presence of a gastric metastasis may affect a patient's therapy, radiographic examination of the gastric fundus should be a routine part of the initial staging and/or follow-up evaluation of esophageal carcinoma.

Gastric metastases of choroid malignant melanoma seem to be exceptional since less than 10 cases have been previously published. We report the case of a 71 year old patient with a gastric melanosarcoma secondary to a choroid malignant melanoma. Gastric metastasis was revealed by digestive bleeding occurring 18 years after right eye enucleation. Gastroscopy showed black ulcerated tumors. Histology confirmed the diagnosis portraying typical melanic pigments within the gastric mucosa. Laser photocoagulation of the gastric lesion was used for the first time in this indication. As a result, hemorrhage decreased and the patient's comfort was improved.

In order to study the mechanism of cancer metastasis, AH100B rat hepatoma cells were transplanted to the stomach of male Donryu rats. Each hepatic metastatic nodule was collected with the respective primary gastric lesions. Each sample thus obtained was injected separately into the peritoneal cavity of male Donryu rats to make free cancer cells; then, intact cancer cells of the hepatic metastatic and primary gastric lesions were collected. After washing in Dulbecco's phosphate-buffered saline (Ca2+ and Mg(2+)-free, pH 7.2), the definite number of the metastatic and primary gastric cancer cells were incubated in the phosphate-buffered saline containing [1-14C] arachidonic acid at 25 degrees C for 30 min. Arachidonic acid metabolites formed during the incubation period were extracted and subjected to thin-layer chromatography, followed by autoradiography. Each radioactive spot was scraped off the plate and measured for its radioactivity. The pattern of the ability to produce PGs was different between the cancer cells which metastasized to the liver and those of the primary lesions, that is, percentage of PGF2 alpha was higher (p < 0.05) and that of PGE2 was quite higher (p < 0.01) in the hepatic metastatic cancer cells as compared with those of the primary gastric lesion. These results suggest that PGs produced by hepatic metastatic cancer cells might play an important role in hepatic metastatic formation.

The "Criteria for Evaluating the Efficacy of Chemotherapy/Radiation Therapy in the Treatment of Gastric Cancer" are now widely used in Japan. To assess the validity of the criteria, the relation between the antitumor effect evaluated by the criteria and the survival of patients with gastric cancer was analyzed. The subjects were 169 patients with unresectable advanced gastric cancer who were entered into a randomized comparative trial of tegafur plus mitomycin C, or UFT (a combination of uracil and tegafur in a 4:1 molar ratio) plus mitomycin C. Irrespective of their performance status, disease extent and chemotherapy regimen, responding patients showed improved survival over non-responding patients. If the primary gastric lesion responded to chemotherapy, prolongation of survival was noted in patients with a measurable gastric lesion as well as in those with a non-measurable but evaluable gastric lesion. No improvement in survival was recognized among patients having a primary gastric lesion which did not respond to chemotherapy, even if the metastases showed a response. The results obtained in the present study indicate the validity of the criteria, except for diffusely infiltrating gastric lesions.

We describe a case of gastric metastasis from a lobular carcinoma of the breast in a 45-year-old woman who had undergone a left mastectomy with axillary dissection 7 years earlier. At the current presentation, she had been experiencing progressive epigastric discomfort for 3 months. The initial diagnosis was early gastric carcinoma, diffuse type, based on gastric biopsy findings and ultrasonographic endoscopy. A definitive diagnosis of metastatic breast cancer was confirmed after subtotal gastrectomy of a presumed primary early gastric carcinoma. Although gastrointestinal metastases from breast cancer are not rare, the early stage of the gastric lesion and the absence of further disease dissemination make this case unusual. The onset of gastrointestinal symptoms in a patient with a history of breast carcinoma should prompt the physician to rule out the possibility of gastric metastases.

Early gastric cancer has an excellent outcome following surgical treatment. In particular, mucosal gastric cancer (m-cancer) very rarely results in metastatic dissemination and may be successfully treated by local surgical resection. We report a 64-year-old Japanese woman who presented with a recurrent cystic lesion on the left bulbar conjunctiva, with a biopsy specimen revealing metastatic signet-ring cell carcinoma. Gastrointestinal investigations revealed an early gastric cancer in the lesser curvature of the stomach. Biopsy specimen of the gastric lesion indicated poorly differentiated adenocarcinoma, which was identical to findings in the lesion in the bulbar conjunctiva. She underwent a distal gastrectomy and made an uneventful recovery. Histopathological analysis indicated a gastric signet-ring cell carcinoma that was limited to the mucosal layer, without evidence of lymphatic spread. Although the exact mechanism of metastatic dissemination to the bulbar conjunctiva is unclear, this case is very unusual, because ocular metastases almost invariably occur in the context of documented and established malignant disease. This is, to our knowledge, the first reported case of a patient with gastric mucosal cancer who presented with a conjunctival metastatic deposit and who subsequently received curative surgical treatment for both conditions.

Melanoma is a neoplasia of dramatically increasing incidence that has a propensity to spread rapidly. Early detection is fundamental and patient management requires reliable, sensitive and reproducible staging methods, such as a single examination by planar scintigraphy or single-photon emission tomography (SPET) using a radiopharmaceutical with selectivity for melanoma tissue. Among iodobenzamides reported to possess an affinity for melanoma, a new compound, N-(2-diethylaminoethyl)-2-iodobenzamide (BZA(2)), was selected for a clinical trial in view of its pharmacokinetic experimental profile in melanoma-bearing mice. Planar whole-body scintigraphy using (123)I-BZA(2) was performed in 25 patients with histologically proven cutaneous melanoma. Performance was evaluated in two groups of patients with one or more documented secondary lesions ( n=13) or with no known secondary lesions ( n=12), and results were compared with those of conventional investigation techniques. No adverse clinical or biological events were recorded. Lesions were imaged by increased tracer uptake, and good quality images were obtained 4 h after administration. After a follow-up of more than 1 year, the overall results of (123)I-BZA(2) scintigraphy on a per patient basis showed a sensitivity of 100%, a specificity of 95%, a positive predictive value of 86% and a negative predictive value of 100%. The proven secondary lesions were imaged with a sensitivity of 100% and a specificity of 91%. In seven patients with suspected metastases, the absence of (123)I-BZA(2) uptake was confirmed as true negative, and in one patient without suspected metastases, (123)I-BZA(2) scintigraphy revealed a gastric lesion. Hence eight diagnoses would have been modified by (123)I-BZA(2) scintigraphy data. (123)I-BZA(2) allowed discrimination between benign and malignant lesions and, in the case of malignancies, between those of melanomatous origin and others. This compound, which is selective for melanoma tissue, appears promising for the staging and restaging of melanoma.

A 66-year-old man was found to have both advanced cancer of the middle thoracic esophagus and advanced cancer of the middle third of the stomach with paraaortic lymph node metastases. The prognosis was poor because of local advanced disease and distant metastasis. The patient was therefore given combined chemotherapy with TS-1 and cisplatin. TS-1 (80 mg/day) was administered on days 1 to 5, 8 to 12, 15 to 19, and 22 to 26 (weekday-on/weekend-off schedule), and cisplatin (70 mg/m2 intravenously over the course of 2 hours) was administered on days 1 and 15 of a 28-day cycle. After 2 courses of chemotherapy the esophageal lesion had a complete response, and the gastric lesion had a partial response (reduction ratio, 71.4%). However, stomatitis and anorexia of grade 2 (NCI-CTC) occurred. Two courses of TS-1 alone (80 mg/m2) were therefore given. The esophageal lesion continued to show a complete response and the gastric lesion a partial response (reduction ratio, 85.7%). There was no change in the para-aortic lymph node metastasis (No. 16a2 latero). No adverse reaction to chemotherapy was severer than grade 3, and a good response was obtained. These findings indicate that chemotherapy with a combination of TS-1 and cisplatin is effective against advanced esophageal cancer and advanced gastric cancer.

Gastric carcinoma is a common malignancy worldwide. Advanced stages of the disease may result in metastases to many other organs of the body. However, colonic metastases are rare. We report a case of gastric carcinoma with symptoms of abdominal fullness and weight loss. The serum carcinoembryonic antigen level was elevated. Esophagogastroduodenoscopy revealed giant folds occupying the whole gastric body and poor expansion of the stomach. Histologic examination of biopsy specimens from the giant fold demonstrated poorly differentiated adenocarcinoma with signet ring-cell differentiation. Total colonoscopy revealed five or six discrete flat elevated lesions in the distal transverse, descending, and sigmoid colons. These lesions were characterized by a clear margin of 3-5 mm in diameter and erosions on the tips. Polypectomy specimens demonstrated signet ring-cell carcinoma, which was histologically similar to the specimens taken from the gastric lesion. We conclude that this was a rare case in which gastric signet ring-cell carcinoma had metastasized to the colon in the form of flat elevated lesions, combined with rapid and wide lymphatic spread to the thorax and abdomen in a clinical course as short as 46 days.
