[Antitumor effect of retinoids (author's transl)]

Retinoids given in a high dosage are able to reduce or prevent the growth of experimental skin tumors in animals. Our study on the systemic effect of aromatic retinoid (Ro 10-9359) on DMBA-induced skin tumors in rabbits supported these findings. The antitumor effect seems to be independent of the type of tumor induction. Previous reports and the possibility of using this retinoid effect in the treatment of skin tumors in man are discussed.
