Insignificant tumor bed effect after pretransplantation hyperthermia.
Effect of pretransplantation hyperthermia of tumor bed on tumor growth was studied. Experimental tumors were isotransplants of a fibrosarcoma which arose spontaneously in C3Hf/Sed mice. The pretransplantation hyperthermia was given at 43.5 degrees fro 120 min by immersing the mouse foot into a constant temperature water bath. This treatment resulted in a similar foot reaction to a single gamma-ray dose of 3500 rads, namely, complete epilation or partial moist desquamation. The pretransplantation hyperthermia failed to retard tumor growth, while the concurrent experiment on pretransplantation irradiation demonstrated marked retardation of tumor growth. No retardation was observed when tumor cells were transplanted into the contralateral untreated feet or into the untreated skin.
