Chemical carcinogenesis and the pancreas
Journal of Surgical Oncology, 1975AbstractAlthough carcinoma of the pancreas is an increasingly prevalent form of human cancer, there has been relatively little experimental work on the etiology of this tumor until recently, probably because of the lack of adequate experimental models. However, at least two good experimental systems are now available.

Clinics in Dermatology, 1989
Abstract The purpose of this review is to update clinical dermatologists about current concepts of chemical carcinogenesis in skin. The incidence of skin cancer is increasing steadily and it has been estimated that of all new cancers diagnosed annually in the United States, almost one third originate in the skin.

ENVIRONMENTAL CHEMICAL CARCINOGENESIS
Medical Journal of Australia, 1978The methodology of revealing and studying chemical carcinogens in the environment is based on epidemiology, animal testing, and short-term laboratory studies. The techniques and limitations of these respective investigations are described. From evidence of carcinogenicity, extrapolation must be made to assess whether a particular substance is a cause ...

Mechanisms of Chemical Carcinogenesis
Annual Review of Pharmacology and Toxicology, 1978Despite the seemingly disparate endpoints, there are similarities between many drugs and chemical carcinogens when viewed from the basis of pharmacological or toxicological principles. Various biochemical reactions or metabolic pathways of chemical carcinogens are the same as those of other xenobiotics.

Cutaneous chemical carcinogenesis
Journal of the American Academy of Dermatology, 1986This review is designed to inform the clinician of current concepts regarding the pathogenesis of chemically induced skin cancer. Chemicals induce cutaneous cancers in a wide variety of experimental animals and in humans. The most common benign experimental tumors are papillomas and keratoacanthomas, whereas common malignancies are squamous cell ...

Inhibitors of Chemical Carcinogenesis
1978Publisher Summary Chemical carcinogens play a very significant role in the etiology of cancer in man. This chapter describes a number of compounds that have the capacity to inhibit the neoplastic effects of chemical carcinogens when administered either prior to exposure to the carcinogen or at the same time.

Carcinogenesis: Chemical and Otherwise
Radiation Research, 1972A review is made not only of the kinds of chemicals which are carcinogenic, but a suggestion is also given about one of the characteristics which may belong to the cells which are chemically transformed. This characteristic has already been shown to be associated with neoplastic cells produced by oncogenic viruses and constitutes the presence of a ...
