The enormous potential that hyperthermia has for benefiting patients with cancer is impressively indicated by biological studies, both in vitro and in vivo, and by comparative clinical studies whenever the heat has been appro priate to the size of the tumor. But hyperthermia, as with any other technologically based medical procedures, requires an extensive develop ment of sophisticated instrumentation and techniques to offer routine clinical benefit. We probably erred in starting clinical trials so soon. We had hoped that by showing the clinical benefits on some superficial tumors quickly, financial support would be stimulated for the required technolog ical developments. Unfortunately, treating superficial disease adequately was more difficult than we had supposed and regional treatments were less successful than we had wished. The physical reasons are clear and were apparent from the beginning, although in our enthusiasm we ignored them. Circumstances are different now. We have to treat a wide range of tumors in various sites, but the systems and techniques required are only available in a few laboratories and clinics where they still are undergoing refinement.

The development of equipment capable of producing and monitoring safe, effective and predictable hyperthermia treatments represents a major challenge. The main problem associated with any heating technique is the need to adjust and control the distribution of absorbed power in the tissue during treatment. Power distribution is considered adequate only when tumor tissue can be maintained at the required hyperthermic levels while, at the same time, healthy tissue is not overheated. This problem is particularly crucial when external heating devices are used to produce hyperthermia. Ex ternal hyperthermia refers to those methods which supply heat to tumor tissue in an external, noninvasive manner, as opposed to internal hyperther mia by which heat is supplied to tumor tissue in situ. Until recently, most of the technical developments and clinical trials of ther motherapy for superficial and deep tumors have been based on elec tromagnetic systems. Presently, there is increasing interest in the use of ultra sound to accomplish these goals. Electromagnetic techniques of external thermotherapy include radiative, capacitive, and, to a lesser extent, inductive procedures. Recent designs for radiative applicators have incorporated microstrip structures. These have the advantage of being compact and lightweight compared with dielectrically loaded waveguide applicators.

Oncothermia is the next generation medical innovation that delivers selective, controlled and deep energy for cancer treatment. The basic principles for oncothermia stem from oncological hyperthermia, the oldest approach to treating cancer. Nevertheless, hyperthermia has been wrought with significant controversy, mostly stemming from shortcomings of controlled energy delivery. Oncothermia has been able to overcome these insufficiencies and prove to be a controlled, safe and efficacious treatment option. This book is the first attempt to elucidate the theory and practice of oncothermia, based on rigorous mathematical and biophysical analysis, not centered on the temperature increase. It is supported by numerous in-vitro and in-vivo findings and twenty years of clinical experience. This book will help scientists, researchers and medical practitioners in understanding the scientific and conceptual underpinnings of oncothermia and will add another valuable tool in the fight against cancer. Professor Andras Szasz is the inventor of oncothermia and the Head of St Istvan University's Biotechnics Department in Hungary. He has published over 300 papers and lectured at various universities around the world. Dr. Oliver Szasz is the managing director of Oncotherm, the global manufacturer and distributor of medical devices for cancer treatment used in Europe & Asia since the late 1980s. Dr. Nora Szasz is currently a management consultant in healthcare for McKinsey & Co.

The next generation of oncological hyperthermia involves the medical innovation of selectively heating up the malignant cells of the body in a controlled way. The easily-distinguishable biophysical and physiological characteristics of cancer cells and their immediate environment are the focus of the targeted energy delivery of this treatment. This heterogenic heating concept breaks with the homogeneous nature of conventional hyperthermia, where an isothermally equal temperature is applied to the large surface area of a solid tumor. Due to its selectivity, the new concept enables the usage of a significantly lower energy, making it safer, less toxic, and easier to use. This book shows the challenges facing oncological hyperthermia, and highlights clinical results obtained in various countries. It also presents discussions about the theoretical basis of the method, adding some technical discussions and clarifying the most difficult points of its design. The contributions dealing with clinical results use state-of-art conventional therapies with complementary hyperthermia and show the advantages of such a combination.

While the establishment of hyperthermia as a routine therapy awaits the results of ongoing controlled clinical trials, the advancement in biological sciences, physics and engineering, clinical physics and dosimetry, as well as clinical implementation continues to make advances. A first attempt to document these advances was made by Dr. Gilbert H. Nussbaum in the Medical Physics Monograph No. 8 of the American Association of Physicists in Medicine, published by the American Institute of Physics in 1982. This monograph is an extension of the above work. The material is divided into six catagories: Hyperthermia Biology, Physics and Engineering, Clinical Physics, Dosimetry and Modeling, Analysis of Clinical Results, and Quality Assurance. There are numerous methods of inducing hyperthermia and there are also equally numerous clinical strategies as expected in an experimental modality. A conscious effort has been made to document the basic information and thus provide an objective learning tool. The material contained herein will be of interest to biologists, physicists, engineers, and physicians who are actively involved in the field of hyperthermia, as well as to those who are anxious to learn about this new field. Some sections provide extremely practical information needed in the routine delivery of treatments and, therefore, will be of benefit to nurses and technologists. We also believe that this material provides insight and guidance for future research.

The present challenge in the treatment of tumors is to reduce the number of patients that still die as a result of primary tumors. Today, the percentage of such deaths remains high at 30%, even when all the common therapeutic methods, namely surgery, radiotherapy, and chemotherapy, are applied. In order to reduce this percentage, new types of radiation sources with a higher linear energy transfer have been intro duced, such as neutrons and pions. Fractionation patterns have been modified and radiosensitizers have been applied to in crease biological efficiency. Studies of the combined application of chemotherapy and radiotherapy have been made to find the best therapeutic effect. In the early 1970s biological findings confirmed the effect of hyperthermia on tumor cells. The first clinical studies on hyper thermia treatment demonstrated that it resulted in better local tumor control. Further application of this treatment modality showed that hyperthermia should be used in addition to radio therapy and chemotherapy. Despite these encouraging results, hyperthermia has not been introduced into common clinical use, due primarily to technical problems. There are a number of methods of transferring heat into tumors; however, with regard to physical conditions, an op timum method has not yet been found. One of the reasons is that up to now we have had no reliable method of obtaining thermal mapping of all parts of the human body. Such measurements are required not only for dosimetric purposes but also for the regula tion of a hyperthermic system.
