The radiosensitization of hypoxic tumor cells by hyperthermia

|March 1, 1975
Abstract:
The influence of hyperthermia on the survival of irradiated oxic and hypoxic HeLa cells was determined. A significant reduction in OER was obtained for irradiated cells subsequently cultivated at 42-degrees C for two hours compared to irradiated cells cultivated at 37-degrees C. These results suggest that heating irradiated hypoxic cells is an effective means of reducing the oxygen dependence factor in radiation effects.
