In November 1997, an expert group was convened to discuss available knowledge on the epidemiology, pathology and mechanisms related to certain tumors that are commonly seen in essays for carcinogenicity in rodents in order that their importance in human hazard evaluation might be assessed. The tumors of interest were urinary bladder carcinomas associated with urolithiasis, microcrystalluria and certain urinary precipitates; renal corticol tumors in male rats associated with alpha-2 urinary globulin nephropathy; and thyroid follicular cell tumors associated with imbalances in thyroid stimulating hormone. Included in the book are a series of individually authored papers on these various topics, as well as a Concensus Report including consideration of how such data may be used within the evalation process in the IARC Monographs on the Evaluation of Carcinogenic risks to Humans.

Presents state-of-the-art regulatory cancer risk assessment models including a biologically based model for two-hit carcinogenesis and cell proliferation! This book comprehensively reviews the various roles of genetic toxicology in human cancer risk assessment conducted by United States and worldwide regulatory agencies-discussing hazard identification, dose-response relationships, exposure assessment, and current practices of risk characterization. Examines predictive values of mutagenicity tests, mechanisms of carcinogenesis, and conventional genotoxicity tests required by the International Conference on Harmonization and the Organization for Economic Cooperation and Development/Environmental Protection Agency guidelines! Comprised of contributions from prominent experts and risk assessors and including nearly 1200 references to facilitate further study, Genetic Toxicology and Cancer Risk Assessment reviews contemporary human cancer genetics as related to the mutagenic nature of carcinogenesis calculates acceptable exposure levels based on a carcinogenic threshold dose for nongenotoxic carcinogens reveals the rationale and methodology of quantitative estimation of human cancer risks using mathematical models discusses the threshold concept of carcinogenesis demonstrates how bacterial mutagenicity assays are the most reliable for predicting rodent carcinogens considers structural activity relationship (SAR) analysis of chemical carcinogenicity describes the emergence of the mouse lymphoma microwell and in vitro micronucleus assays illustrates the use of genetic biomarkers for dosimetry analysis and more! Linking human cancer genetics, mutagenicity assays, mechanisms of carcinogenesis, carcinogenic thresholds, molecular epidemiology, mathematical modeling, and quantitative cancer risk analysis, Genetic Toxicology and Cancer Risk Assessment is a must-have reference for toxicologists; oncologists; geneticists; biostatisticians; reproductive, developmental, cell, and molecular biologists; endocrinologists; biochemists; and upper-level undergraduate, graduate, and medical school students in these disciplines.

Offers comprehensive coverage of currently available cancer predictors, the most recent research on carcinogenicity, and the design and interpretation of carcinogenicity experiments. Presents mouse, rat, and human carcinogenicity data for the liver, kidney, breast, cervix, prostate, hematopoietic system, colon, skin, urinary bladder, mouth, stomach, thyroid, and pancreas.

Following the success of the first edition, this book is designed to provide practical and timely information for toxicologic pathologists working in pharmaceutical drug discovery and development. The majority of the book (Organ Systems) will provide detailed descriptions of histopathological lesions observed in drug development. In addition, it will provide information to assist the pathologist in making determinations of the origin of lesions as well as its relevance to human risk. Toxicologic Pathology: Nonclinical Safety Assessment, Second Edition includes 2 new concept chapters. The first of the new chapters address approaches for the evaluation of unique therapeutic modalities such as cell therapies, gene therapies, and gene expression knockdown therapies. While these still represent new developing therapeutic approaches, there has been significant experience with the therapeutic modalities in the last 5 years. The second new chapter addresses the nonclinical safety assessment of medical devices, a topic of increasing importance that was not addressed in a unique chapter in the first edition. The other concept chapters have been updated and cover important topics including the overview of drug development; principles of nonclinical safety assessment; an introduction to toxicologic pathology; techniques used in toxicologic pathology, clinical pathology, toxicokinetics, and drug development toxicogenomics; and spontaneous lesions. The 13 organ system chapters provide the specifics related to pathologic characteristics, differential diagnosis, and interpretation of toxic responses in each organ system. These chapters are specifically important for the bench pathologist but also for the toxicologist who interacts with pathologists and function as study toxicologists and project team representatives in the drug development arena.

Boorman's Pathology of the Rat: Reference and Atlas, Second Edition, continues its history as the most comprehensive pathology reference on rat strains for researchers across science and medicine using rat models in the laboratory. It offers readers an added emphasis on the Sprague-Dawley and Wistar rat strains that is consistent with current research across academia, government, and industry. In addition, the book provides standard diagnostic criteria, basic content on histology, histological changes that result from drug toxicity and neoplasm, pathology terminology, and four-color photographs from the NTP archive and database. With updated references and photographs, as well as coverage of all rat strains, this book is not only the standard in the field, but also an invaluable resource for toxicologists, biologists, and other scientists engaged in regulatory toxicology who must make the transition from pathology results to the promulgation of meaningful regulations. - Contains full, four color photographs from the NTP archive and database and coverage of all rat strains - Provides an organ-by-organ and system-by-system approach that presents standard diagnostic criteria and basic content on histology and histological changes - Includes comprehensive and detailed background incidence data - Presents detailed descriptive content regarding changes in rat models during research
