Chemoprevention of cancer with retinoids.
The importance of retinoids for chemoprevention of cancer has received further emphasis with the finding that retinoids can suppress in vitro expression of the malignant phenotype, whether it be caused by chemical carcinogens, radiation, or viral transforming factors. Retinoids have been found to be potent inhibitors of the tumor-promoting effects of phorbol esters. Further advances in the chemistry of synthetic retinoids have led to the development of new agents that show less toxicity and better targeting to specific organ sites than natural retinoids. Synthetic retinoids have been particularly useful for prevention of bladder and breast cancer in experimental animals.
