Results of a clinical trial with vitamin A, which took place in Japan for the treatment of cancers, and results of epidemiological studies on the relation between food intake and development of lung cancer in Japan are reported. Several Japanese groups are studying the combined effect of vitamin A and its derivatives and anticancer chemotherapeutic agents on the growth in vitro and in vivo of cancer cells, but few clinical trials of those combinations for cancer treatment have been made. The results of those few studies are reviewed.
