What is local hyperthermia?
We use local hyperthermia to shrink tumors by using heat to damage proteins and structures within cancer cells.
Local hyperthermia (sometimes called superficial hyperthermia) exposes a small area, such as a tumor, to high temperatures. Hyperthermia can be used with radiation therapy, chemotherapy and biotherapy/immunotherapy.
How does local hyperthermia work?
Using MRI guidance, we first locate the tumor that will be treated. The tumor is then heated externally or internally:
- External – The area may be heated externally with high-frequency energy waves aimed at a tumor from a device outside the body.
- Internal – Probes or antennas are placed inside the tumor to deliver energy and to heat the area directly. Several types of sterile probes may be used. Radiofrequency ablation (RFA) is a type of internal hyperthermia that uses high-frequency energy to heat and destroy cancer cells.
Local hyperthermia offers a promising treatment option for patients with advanced or recurrent cancer.
