Over 80 per cent of gastric cancers and peptic ulcers occurred within 2 cm of both a mucosal junction and the lesser curvature. They showed slight differences in their longitudinal relationship to the pyloric junction. There were differential characteristics between the groups of cancers arising at each of the three mucosal junctions. Cancers at the pylorus and cardia were more common in males (M:F--2.6:1) and were predominantly well differentiated, whereas those from the intermediate zone were more common in females (M:F--1:1.8) with a relatively higher proportion of undifferentiated cancers.

The tumour produced a considerable weight loss (greater than 25 per cent) in the mice at a stage when it comprised less than 5 per cent of the total body weight. A slight fall in food intake of the tumour-bearing mice was noted, but animals bearing other non-cachectic mouse and human tumours had much lower food intakes without accompanying weight loss. No obvious defects in gastrointestinal absorption were detected nor was any gross increase in basal metabolic rate observed. The precise mechanism producing the severe cachexia remains to be established, but elaboration of humoral factors by the tumour seems probable. This model of cachexia bears a closer relation to the clinical situation than do other experimental animal tumour models currently available.</p>","PeriodicalId":75950,"journal":{"name":"Investigative & cell pathology","volume":"2 2","pages":"87-96"},"PeriodicalIF":0.0,"publicationDate":"1979-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11715405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Changes in hormonal status that increase breast cancer risk probably do so by 'promoting' tumour development rather than by 'initiating' it. Exogenous oestrogens seem to act as tumour promoters in this context, but there is to date no evidence that oral contraceptives, some of which contain oestrogens in low dosage, increase breast cancer risk. On the contrary, they appear to reduce the incidence of benign breast tumours. Prolactin-release is associated with increased mammary tumour incidence in rats but not in humans. There is no evidence that viruses or exposure to hair-dyes increase breast cancer risk. The fact that slight dietary restriction can dramatically reduce mammary tumour incidence in rats, suggests that dietary factors should be looked at more closely in the search for aetiological factors in man.</p>","PeriodicalId":75950,"journal":{"name":"Investigative & cell pathology","volume":"2 1","pages":"45-53"},"PeriodicalIF":0.0,"publicationDate":"1979-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11443829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
