Alkalization of blood pH is responsible for survival of cancer patients by mild hyperthermia.
The effect of mild hyperthermia on venous blood pH was examined in 6 cancer patients. Mild hyperthermia was induced by continuation of a rectal temperature of 39.5 degrees C for 30 min. All 6 patients were diagnosed as suffering from advanced cancer with or without surgery and chemotherapy pretreatments. In Cases 1 to 5, but not Case 6, venous blood pH was alkalized up to pH 7.7 by this mild hyperthermia and the effect was reproduced depending on the application of hyperthermia. At this time, alkalized pH was accompanied by increased PO2 and decreased PCO2 in the blood. These patients showed good physical conditions and improved clinical data. On the other hand, hyperthermia could not be continued in Case 6 due to his worsened physical condition. The present data suggest that mild hyperthermia is a useful method to improve circulation failure, physical condition and clinical data.
