Low molecular weight homopolymers of itaconic anhydride having average molecular weights of from about 400 to about 5000 and derivatized to contain (a) half-amide, half-carboxyl acid groups and (b) imide groups in which said imide groups comprise from about 3% by weight to about 35% by weight of said derivatized groups, and the pharmaceutically acceptable cationic salt derivatives of said derivatized homopolymers, have antitumor activity.
