Criteria for Classification of Neoplasms for Pathologists and Statisticiansed from rodent carcinogenesis studies (Greaves and Faccini, 1984). It is evident that statistical analysis of such pathology data will continue to be essential for the process of human risk estimation. Much of this data is tabulated (converted to numbers) on the basis of classification schemes selec

Factors Affecting Histopathologic Interpretation of Toxicity—Carcinogenicity Studies adverse effect. These studies are conducted in laboratory animals. One of the key elements in interpretation of these studies is the histopathologic evaluation of tissues from the test animals. From this evaluation, the incidences of various lesions observed can be compared between treated and cont

One way of overcoming the difficulty introduced by varied nomenclature and diagnostic criteria is to have the primary pathologist or several pathologists re-evaluate histological sections of the tissue in question from a defined series of historical control groups.
