Carcinostatic composition containing an oily substance such as a glyceride and 3-N-o-toluyl-5-fluorouracil suspended therein. The composition exhibits a remarkable carcinostatic effect against various cancerous cells at a low dose and has less side-effects than 5-fluorouracil and its known derivatives which have been typical carcinostatic compounds. A process of producing carcinostatic composition comprises dispersing 1,3-di-N-acyl-5-fluorouracil into an oily substance such as a glyceride to prepare an emulsion and selectively substituting a hydrogen atom only for the 1-position acyl group, whereby the compound is acylated only at the 3-position and which is a chief constituent of the carcionstatic composition.
