Texas Oncology’s radiation oncologists use advanced treatment planning systems and technology tools in the fight against radio-resistant and recurrent cancer. One of the more specialized tools available is called hyperthermia treatment, which attacks tumors with the additive effects of precisely delivered therapeutic heat.
Researchers have found that elevated temperatures can disrupt and destroy a cancer cell’s ability to repair DNA damage from radiation within malignant tumors. As the cancer cells try to reproduce, they die, and the cancer tumor shrinks. Normal cells recover without the long-term damage. Hyperthermia therapy uses heat applied directly to the cells to destroy cancer cells or make them more sensitive to enhance the effects of more conventional treatments, such as chemotherapy and radiation.
It works by a multitude of mechanisms, for example:
The hyperthermia therapy is administered by the Pyrexar-500, a powerful microwave system that delivers heat energy directly into the cancerous tumor at temperatures between 104-113 degrees Fahrenheit. This treatment has been shown to destroy malignant tumor cells, while minimizing damage to the surrounding healthy tissue. When used as part of a combined treatment regimen, hyperthermia improves the effectiveness of other cancer treatments, such as radiation and chemotherapy.
Hyperthermia therapy can be delivered locally or regionally.
The hyperthermia treatment technology has been approved by the U.S. Food and Drug Administration to treat malignant tumors on the surface of the body (superficial) or deep in the body (interstitial). Hyperthermia is used for cancers of the skin such as melanoma, or squamous and basal cell carcinomas, some of which have recurred after conventional treatment. In addition, it is used for select cancers of the rectum, prostate, and cervix. It is covered by most insurances and Medicare.
