Abstract

The cytotoxicity of cisplatin, applied alone or in combination with hyperthermia, to mouse mammary adenocarcinoma cells (M8013S) was studied with the cells either treated in medium [Eagle's minimum essential medium (MEM), supplemented with 10% foetal bovine serum, 100 IU/ml penicillin, 200 mM glutamine and 0.35 g/l NaHCO3] or in Hank's balanced salt solution (HBSS) without serum. To study the role of platinum uptake by the M8013 cells in cytotoxicity, uptake was determined under conditions similar to those used in the survival experiments. Our results show that hyperthermia (30 min at 43°C) enhances the toxicity of cisplatin. Enhanced toxicity by heat treatment is not observed with the cells in HBSS. The thermal enhancement of effects of cisplatin to cells in MEM with serum is clearly related to an enhanced uptake of cisplatin. A novel observation is that in order to obtain a considerable thermal enhancement of the cytotoxic effect of cisplatin, the exposure of the cells to the drug is required not only during the hyperthermic treatment but the exposure has to be maintained for at least 2 h after hyperthermia. These same conditions are also required for enhanced uptake of cisplatin. The present results may indicate that cisplatin has to be bound to some serum component in order to facilitate an ‘active’ uptake. Hyperthermia leads to a considerable intracellular accumulation of cisplatin, relative to the extracellular concentration. This accumulation takes place during exposure to cisplatin but after heat treatment.
