Two 8-month-old and two 4-month-old male beagle dogs received 250 ml of 150 microgram/ml solution of N-ethyl-N'-nitro-N-nitrosoguanidine (ENNG) and 2% Tween 60 mixed with a pellet diet twice a day for 8 months as the same methods used for mongrel dogs in our first report [Juntendo Medical Jouranl 19, 579-583 (1973)]. Gastric carcinomas with distant lymph nodes metastases occurred in three beagle dogs except for one died from anesthesia at the endoscopy. Metastases to the liver were observed in two beagles. In the most long-lived beagles, peritonitis carcinomatosa with ascites and metastases to the liver, lungs, bones, and skin were found. Main gastric tumors were located at the subcardia in two dogs (elevated tumor in dog No. 6, ulcerated tumor in dog No. 8), but in dog No 7 at the angulus (ulcerated tumor). Histologically, carcinomas were composed of poorly differentiated adenocarcinoma, signet-ring cell carcinoma, tubular adenocarcinoma, and undifferentiated adenocarcinoma. In all of three dogs which developed adenocarcinoma of the stomach, Stewart's criteria were completely satisifed. Using our methods the target organ is limited only to the stomach, without any sarcomatous lesion of the intestines.

A case of mucinous adenocarcinoma of the stomach is described in a 20-month-old child with a large abdominal mass. The lesion arose from the lesser curvature of the stomach and invaded the submucosa and lymphatic channels. A partial response to chemotherapy, including vincristine, Cytoxan, actinomycin D, and adriamycin, was noted, but the patient died 3 1/2 months following diagnosis shortly after gastric perforation and peritonitis developed. Autopsy revealed a pattern of widespread visceral metastases, accompanied by pathologic findings suggestive of ataxia-telangiectasia. A diagnosis of mucinous adenocarcinoma, although it is rare, should be considered in the evaluation of primary neoplasms of the stomach in children.

Cells (1 X 10(7)/0.5 ml) from a Borrmann type III poorly differentiated adenocarcinoma of the human stomach were injected ip into nude mice. The injection resulted in ascites carcinoma with invasion (carcinomatous peritonitis) and liver metastasis. The inoculum was obtained from subcutaneous tumors at passage 9 in nude mice that had received serial transplants from the patient with Borrmann type III poorly differentiated adenocarcinoma of the stomach. Serial transfers of 1.5 X 10(6) dispersed cancer cells/0.5 ml into the peritoneal cavity of nude mice converted this adenocarcinoma to an ascites form. Hemorrhagic ascites accumulated within 3 weeks at the first passage and 4-6 weeks in serial passages. Carcinomas peritonitis occurred consistently and was observed in the diaphragm, mesenteries, omentum, and pancreas; metastases were seen in the liver and spleen. Subsequently, iv injection of ascites at passage 3 (6 X 10(5) cells/0.2 ml) into nude mice produced metastatic lesions in the lung and the heart. The histology of the invasive and metastatic lesions in the nude mice was similar to that of the original tumor in the patient with stomach carcinoma.

A case of heterotopic ossification in the pulmonary metastases of an adenocarcinoma of the stomach is presented. This report represents the second known case in the world literature. Three cases with ossification in the primary tumor of the stomach and three cases of colorectal adenocarcinoma with ossification in the pulmonary metastases have been reported. The findings in these reports are reviewed and compared with those in the present case. The observations in these cases are consistent with the theory that heterotopic ossification in tumors and/or their metastases is due to metaplasia of fibroblasts induced by the presence of malignant cells.

A 50-year-old white man complained of "inflammation" of his right eyelid since January 1989. In June 1990, he had undergone a gastrectomy for an adenocarcinoma of the stomach. In August 1990, his right eye showed a painless, firm infiltration of the upper and lower lid, ulceration and loss of eyelashes of the upper lid and a reddish, subepithelial thickening of the medial bulbar conjunctiva. Biopsies of the right upper lid and nasal bulbar conjunctiva disclosed a metastatic, poorly differentiated adenocarcinoma of the stomach (signet ring cell carcinoma) both in the lid and conjunctival biopsies. Carcinoembryonic antigen (CEA) was detected in the tumor cells. Electron microscopic examination revealed tumor cells with signs of secretory activity. Although metastases to the eyelids and conjunctiva are rare, they may precede the clinical manifestation of the primary tumor for months or even years. In patients with chronic, recalcitrant lesions of eyelids or conjunctiva, especially if accompanied by loss of eyelashes, a primary or secondary malignancy should be excluded by early biopsies and histopathological examination.

A 73-year-old female was admitted to our hospital because of weight loss and pretibial edema. Plasma levels of adenocorticotropic hormone (ACTH) and cortisol were elevated, and neither hormone showed circadian rhythm. Dexamethasone (2 mg for 2 days) failed to reduce the urinary excretion of 17-hydroxycorticosteroids and the plasma cortisol level. The stomach biopsy specimens showed a moderately-differentiated papillo-tubular adenocarcinoma. Computed tomography of the abdomen showed multiple metastases to the liver. Immunohistochemical staining of the autopsy specimens showed immunoreactive ACTH in the primary tumor cells of the stomach as well as the metastatic tumor cells of the liver. On the basis of the clinical, histological and immunohistochemical findings, we diagnosed this patient as having ectopic ACTH syndrome caused by adenocarcinoma of the stomach.

The c-erbB-2 protooncogene encodes a possible growth factor receptor. This gene has been studied as to whether it can be regarded as a prognostic indicator in human breast carcinoma. As amplification and overexpression of the gene have been reported in several adenocarcinomas, 24 specimens of human gastric cancers were examined by immunohistochemical staining (24 cases), by Southern blotting (23/24) and by Northern blotting (16/24). Amplification of the gene was detected in two moderately differentiated tubular adenocarcinomas (8.7%), and overexpression of c-erbB-2 mRNA was detected in three moderately differentiated tubular adenocarcinomas (18.8%). By immunohistochemical staining of paraffin-embedded tissues using a polyclonal antibody to c-erbB-2 gene products, the cell membrane was stained positively in three cases of gastric cancers which overexpressed c-erbB-2 mRNA. Peritoneal metastases were found in six gastric cancers, including two moderately differentiated tubular adenocarcinomas in which amplification of c-erbB-2 occurred. These results suggest that amplification and overexpression of c-erbB-2 may be correlated with metastases in differentiated adenocarcinoma of the stomach.

A patient with signet ring adenocarcinoma of the stomach with metastatic disease to the breast treated at our institution is presented and added to the 14 cases reported in the literature. A review of the common clinical features and possible mechanisms of metastases is given. While the majority of patients present with symptoms referable to their gastric malignancy, the patient in this case initially sought treatment because of her breast mass. Metastatic deposits within the breast may be difficult to distinguish from primary breast carcinoma. For this reason, immunohistochemistry utilizing carcinoembryonic antigen (CEA), C-ERB B-2, and gross cystic protein were used in this case to confirm an extramammary source. In order to prevent unnecessary breast surgery and provide proper treatment of the gastric primary, the patient's complete clinical presentation must be used to guide diagnostic evaluation.

Percutaneous ethanol injection (PEI) was performed under ultrasound (US) guidance in the outpatient department in 14 patients with 21 metastases 1.0-3.8 cm in diameter. The primary cancer was colorectal adenocarcinoma (seven patients), adenocarcinoma of the stomach (four patients), abdominal leiomyosarcoma (one patient), gastrinoma of unknown origin (one patient), and bronchial carcinoid (one patient). The indicators of therapeutic efficacy were US, computed tomography, fine-needle biopsy, and serologic markers. No complications occurred after a total of 175 treatment sessions. Complete response was obtained in 11 lesions, nine of which were less than 2 cm in diameter, and in all endocrine metastases (four lesions in two patients) with a maximum, recurrence-free follow-up of 38 months. Carcinoembryonic antigen values decreased in all patients but one for a 2-6-month period. The natural course of metastatic disease strictly limits the applicability of PEI, a local treatment. Single, metachronous, nonoperable metastasis of adenocarcinoma and endocrine metastases seem to be the only indications for PEI.

The authors analyse the incidence of metastases into the bone marrow in carcinomas of the stomach, pancreas, liver and gallbladder. Specimens from the bone marrow taken were by trephine biopsy from the sternum, ala ossis ilii and spine. Metastases into the bone marrow were found in carcinomas of the stomach, pancreas and gallbladder but not in hepatic carcinoma. Neoplastic metastases were most frequent in adenocarcinoma of the stomach.
