title: A nontoxic system for 41.8 degrees C whole-body hyperthermia: results of a Phase I study using a radiant heat device.
abstract: A Phase I study of whole-body hyperthermia (WBH) (52 treatments/12 patients) was completed with no significant clinical toxicity. The study incorporated a thermal dose escalation scheme from 39.5 degrees-41.8 degrees C for up to 151 min. A radiant-heat device was utilized for producing WBH. During WBH, patients were sedated; endotracheal intubation was not required. No changes in cardiovascular, respiratory, hematological, or biochemical indices requiring clinical intervention occurred during the study. We conclude the radiant-heat device coupled with a defined pharmacological approach to WBH with appropriate patient screening yields a system for 41.8 degrees C WBH which is safe and efficient, is not labor intensive, and does not require general anesthesia and endotracheal intubation. This system is appropriate for a multimodality approach to various systemic cancers.
