Clinical Experience of Interstitial Thermoradiotherapy Using Ferromagnetic Implant Techniques
Interstitial hyperthermia commands much current interest as a method for delivering localized heat treatment to deep-seated as well as superficial tumors. Several interstitial techniques have been developed and used clinically over the past two decades. Interstitial techniques are popular since they can circumvent some problems encountered with non-invasive hyperthermia techniques, such as limited penetration, inefficient and nonuniform power distribution, and excessive heating of adjacent normal tissues. On the other hand, interstitial hyperthermia is an invasive technique and it usually requires general anesthesia. Some patients with bleeding disorders may not be candidates for such an approach. Furthermore, due to the localized nature of the treatment, the resulting temperature distribution may be highly dependent on the blood flow and geometry of the implant. Three major classes of interstitial hyperthermic techniques have been described and developed: interstitial radiofre quency electrodes (IRF), interstitial microwave antennas (IMW), and hot source techniques.
