These parameters and the pathological lesions (preneoplastic foci, neoplastic nodules and hepatomas) have been followed up after stopping the DENA feeding. A good correlation has been found between the malignant transformation of preneoplastic foci and the breakdown of the mitotic control. In animals treated by DENA for two weeks, the homeostatic control of mitoses remains normal for a minimum of <em>14</em> months and ‘preneoplastic foci’ persist without any further malignant transformation. After DENA feeding for <em>4</em> and <em>6</em> weeks, the subsequent malignant transformation occurs as a function of the mitotic disturbance: the longer the DENA feeding, the faster the homeostatic disturbance, the earlier the conceration. After DENA treatment for <em>10</em> weeks, the homeostatic regulation is lost and the neoplastic growth is triggered at the time of the DENA feeding cessation. In this case, the pattern of canceration is the same as when DENA is given continuously up to the time of death. It is concluded that ‘preneoplastic foci’ induced during the first two weeks of treatment cannot by themselves transform into a malignant tumor. To commit them irreversibly into malignancy, a subsequent action of the carcinogen is necessary; it may consist of the irreversible breakdown of the normal homostatic regulatory mechanism of liver cell proliferation.</p></div>","PeriodicalId":100497,"journal":{"name":"European Journal of Cancer (1965)","volume":"17 2","pages":"Pages 149-154"},"PeriodicalIF":0.0,"publicationDate":"1981-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0014-2964(81)90029-3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17514361","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}
