Whole-body hyperthermia raises the temperature of the entire body into the treatment range. It is generally used in the context of disease that has spread to multiple sites throughout the body, and because it involves a whole-body systemic response, it requires close monitoring.
How is whole-body hyperthermia generally delivered?
According to general material from the National Cancer Institute (NCI), whole-body hyperthermia may be delivered using heated blankets, thermal chambers, or warm water immersion to gradually raise and maintain body temperature within the treatment range, with continuous monitoring of heart rate, blood pressure, and other physiological indicators throughout.
How does whole-body hyperthermia differ from local and regional hyperthermia?
| Category | Heated area | General monitoring needs |
|---|---|---|
| Local hyperthermia | A single small lesion | Relatively simple |
| Regional hyperthermia | A larger body region or organ | Moderate to higher |
| Whole-body hyperthermia | The entire body | Higher, requiring close monitoring of physiological indicators |
What is the current state of use for whole-body hyperthermia?
Because whole-body hyperthermia involves a systemic physiological response, monitoring requirements are higher, and it is currently most often seen in specific clinical research settings. Actual availability depends on each country’s regulatory approval and clinical indications — it is not a widely used routine treatment.
Because whole-body hyperthermia involves a systemic physiological response, risk considerations and monitoring requirements are generally higher than for local or regional hyperthermia. Actual suitability and safety should be individually assessed by the care team; this page is a general technical overview only.
Is whole-body hyperthermia dangerous?
Because it involves a whole-body systemic response, whole-body hyperthermia generally needs to be performed at a medical facility with complete monitoring equipment and a professional team. Actual risk level depends on the device, parameter settings, and the individual patient's health status, and should be fully assessed by a physician before deciding suitability.
