In accordance with the present invention, a method is provided for treating tumors. More particularly, the present invention relates to a method for treating tumors comprising injecting a solution of certain ethylene oxide-propylene oxide surface-active copolymers and a solution containing chemotherapeutic agents into a human or animal with a tumor. The solutions can be injected simultaneously or separately at different times. In addition, the surface-active copolymer and the chemotherapeutic agent can be in the same solution. The surface-active copolymer can be an ethylene oxide-propylene oxide condensation product with the following general formula: HO(C2H4O)b(C3H6O)a(O2H4O)bH wherein a is an integer such that the hydrophobe represented by (C3H6O) has a molecular weight of approximately 950 to 4000 daltons, preferably approximately 1200 to 3500 daltons, and b is an integer such that the hydrophile portion represented by (C2H4O) constitutes approximately 50% to 90% by weight of the compound.
