[Methods for creating hyperthermia in tumors by using electromagnetic fields].

Evidence on the methods for creation of hyperthermia in treatment of human tumours using superhigh-frequency external, intracavitary, and implanted irradiators are generalized. Inductive, capacitive and interstitial methods of heating are described. Advantages and shortcomings, depths of heating and heat-production structures are presented for each method. The known devices for regional hyperthermia are considered.

Development of a new heating needle for interstitial hyperthermia compatible with interstitial radiotherapy.

We have developed a new heating needle for interstitial hyperthermia compatible with brachytherapy. We studied the heating characteristics of interstitial needles and the usefulness of these needles for interstitial hyperthermia. As heating needles, we used MicroSelectron HDR interstitial needles. These needles were only heated at the metal tip, and were insulated in the middle and grounded from the top. The hyperthermia system was based on the principles of RF capacitive heating, and we used a Thermotron RF-8. We examined whether the temperature and the heating area could be elevated to a level required for hyperthermia. Good heating was obtained around the metal tip of the needle. The heating area of the longitudinal axis of the needle varied with the length of the metal part, while the transverse heating area of the needle was almost unchanged. If heating was performed while maintaining the elevation of temperature in each needle at the same level using variable coils (tuning box), heating was homogeneous over the regions in accordance with the arrangement of the needles. With this heating system, the temperature rises easily, and a uniform temperature distribution can be obtained.

Deep local hyperthermia for cancer therapy: external electromagnetic and ultrasound techniques.

External heating techniques for delivery of localized hyperthermia in patients are reviewed. This paper covers microwaves, radiofrequency, and ultrasound methods. Fundamental principles governing tissue absorption, guidelines for applicator selection and design, and restrictions of each heating approach are discussed. Innovative techniques utilizing multiple applicators to achieve better heating uniformity are also presented. The advantages and disadvantages of electromagnetic versus ultrasound heating techniques are compared as a conclusion to this review.

[Radiators for electromagnetic hyperthermia of malignant intracavitary neoplasms].

Rod radiators of electromagnetic field designed for electromagnetic hyperthermia of tumors of the body cavities were developed. Their main parameters were investigated in laboratories. Experimental samples of radiators were advanced for clinical trial in the leading cancer institutes of the country.
