Whole-body hyperthermia in cancer therapy: a report of a phase I-II study

Twenty-seven patients were treated with whole-body hyperthermia alone or in combination with either chemotherapy or radiotherapy. Whole-body hyperthermia was performed in the Pomp-Siemens cabin with hot air and a warm water mattress, the patient being covered with plastic film to avoid cooling by perspiration. The heat treatment lasted for 2 hr at 41.8-42.0 degrees C. Toxicity, such as liver damage and respiratory problems, was considerable. There were two fatalities. Hyperthermia gave an improved therapeutic effect in 6 of the patients. Considerable pain relief was observed in 8 of 10 patients. Whole-body hyperthermia at 42 degrees C can be effective but the potential toxicity limits its use to those patients with severe complaints for whom no other palliative treatment is available.
