Types of Treatments
Hyperthermia is a form of therapy where heat is used to enhance the effectiveness of radiation and chemotherapy and to destroy tumors. Recent randomized clinical trials have clearly demonstrated the benefit of adding hyperthermia to radiation therapy and/or chemotherapy for the treatment of recurrent breast cancer, melanoma, head and neck cancer, prostate, cervix, and other sites of locally advanced or recurrent cancers. Hyperthermia is especially useful for re-treatment of previously radiated sites. Our faculty and staff are experienced and internationally recognized experts in the field of hyperthermia and radiation therapy.
Our comprehensive clinical service has state-of-the-art ultrasound, microwave, and electromagnetic/RF (radio frequency) technologies that allow us to selectively tailor the hyperthermia treatment to patient-specific requirements. Our external ultrasound and microwave applicators are used to heat superficial tumors up to approximately 8 centimeters deep. Interstitial and endocavity microwave applicators can be used for deep-body sites treated with high dose rate (HDR) brachytherapy. Our electromagnetic deep heating system can treat sites deep within the body.
How it Works
Hyperthermia is most often used to treat tumors that are close to the surface of the body. A special device called a surface applicator is applied over the region of the tumor. The tumor area is heated to a temperature of 40-43oC (104-109oF) for approximately one hour. Hyperthermia treatments are given within one hour of radiation therapy or chemotherapy. Hyperthermia can also be used to treat deeper tumors using interstitial sources when combined with high dose rate (HDR) brachytherapy or a deep-heating system. In addition to the standard of care hyperthermia, we are also supporting the following clinical trials:
- Recurrent breast cancer
- Locally advanced breast tumors
- Locally advanced cancers of the uterus, cervix and prostate
- Neck tumors
- Advanced, persistent tumors
- Large, bulky tumors
- Active hyperthermia program since 1986
- Multi-modality, state-of the art equipment
- Ultrasound, microwave, and electromagnetic/radio frequency treatment procedures
- Interstitial devices for conformal hyperthermia with HDR brachytherapy
