A method for treating a neoplastic disorder in a subject includes administering to the neoplastic cells a neoplastic cell-sensitizing composition including a poly(ethylene oxide)-poly(propylene oxide) copolymer. The poly(ethylene oxide)-poly(propylene oxide) copolymer can sensitize the neoplastic cells to hyperthermia. Energy can be applied to the neoplastic cells to heat and ablate the cells.
