Abstract

An antitumor agent comprising a combination of 5-fluorocytosine and cytosinedeaminase has been developed. As to the practical administration procedure of the agent, it is preferable to carry out in such a manner that 5-fluorocytosine is first administered in any portion of the body, and cytosinedeaminase is then administered into the topically suffered portion. The administered 5-fluorocytosine is transferred into the suffered portion, and the 5-fluorocytosine is affected with the action of cytosinedeaminase to convert the former compound into 5-fluorouracil, resulting in that the necrosis of the tumor tissue is caused.
