Abstract

We investigated the ischemia-reperfusion-induced tumour growth delay as a function of ischemic time, tumour temperature, and the amount of inspired oxygen during reperfusion. The rhabdomyosarcoma R1H growing on the right flank of male WAG/Rij rats was clamped for 2 or 4 h at 20 degrees C or 37 degrees C. Five minutes prior to and 10 min during reperfusion the animals respired air, pure oxygen or carbogen (95% O2, 5% CO2). Comparison of single treatment modalities with untreated controls revealed significant tumour growth delays after clamping times of 4 h at 37 degrees C for air and pure oxygen, but not for carbogen.
