This book was released on 2012-12-06 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2012-12-06 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Internal" hyperthermia is a type of thermotherapy by which heat is sup plied to tumor tissue in situ. There are three different techniques for pro viding internal hyperthermia: (1) interstitial hyperthermia using implanted needle probes, (2) intracavitary hyperthermia using probes introduced into natural body cavities, and (3) perfusional hyperthermia by means of ex tracorporal blood heating. Compared with external hyperthermia, internal hyperthermia has been preferentially accepted by oncologists because it can be more easily combined with other forms of treatment, e. g., interstitial thermotherapy with brachytherapy, or perfusional hyperthermia with che motherapy. Various types of equipment for interstitial and intracavitary thermotherapy have been developed and used quite extensively in clinical trials, generally in combination with radiation therapy. There are four different methods for producing interstitial or intracavitary hyperthermia, each related to different types of heating. Most studies have been performed using radiofrequency electrodes (resistive heating) or coaxial microwave antennas (radiative heating). Recently, however, "hot source" techniques that rely on thermal conduction and blood flow convection for heat transport have found clinical application. These techniques include ferromagnetic implants activated by hot water or by electrical means. In the near future, new methods for in terstitial or intraluminal heating based upon advanced ultrasonic and laser technologies will be developed.

Download or read book Oncothermia Principles and Practices written by Andras Szasz and published by Springer Science & Business Media. This book was released on 2010-11-23 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2012-12-06 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hyperthermia has been found to be of great benefit in combination with radiation therapy or chemotherapy in the management of patients with difficult and com plicated tumor problems. It has been demonstrated to increase the efficacy, of ionising radiation when used locally but also has been of help in combination with systemic chemotherapy where hyperthermia is carried out to the total body. Problems remain with regard to maximizing the effects of hyperthermia as in fluenced by blood flow, heat loss, etc. The present volume defines the current knowledge relative to hyperthermia with radiation therapy and/or chemotherapy, giving a comprehensive overview of its use in cancer management. Philadelphia/Hamburg, June 1995 L.W. BRADY H.-P. HEILMANN Preface In an attempt to overcome tumor resistance, hypoxia, or unfavorable tumor condi tions, oncological research has come to focus on gene therapy, immunotherapy, new cytotoxic agents, and increasingly sophisticated radiotherapy. Radiation research has been directed towards heavy particle therapy and modification of the radiation response by either protecting or sensitizing agents. Improved dose localization using rotational or conformal strategies has also been implemented. Recently, changes in radiation fractionation schedules have shown promise of better results. Hyperthermia in cancer therapy can be viewed similarly as another means to increase the sensitivity of tumors to radio- and chemotherapy.

Available in PDF, EPUB and Kindle. Book excerpt: In the 1960s a firm rationale was developed for using raised temperatures to treat malignant disease and there has been a continuous expansion of the field ever since. However, a major limitation exists in our ability to heat human tumours, especially those sited deep in the body, with a reasonable degree of temperature uniformity. This problem has resulted in engineers and physicists collaborating closely with biologists and clinicians towards the common goal of developing and testing the clinical potential of this exciting treatment modality. The aim of the physicist and engineer is to develop acceptible methods of heating tumQur masses in as many sites as possible to therapeutic temperatures avoiding excessive heating of normal structures and, at the same time, obtaining the temperature distribution throughout the heated volume. The problem is magnified by both the theoretical and technical limitations of heating methods and devices. Moreover, the modelling of external deposition of energy in tissue and knowledge of tissue perfusion are ill-defined. To this must be added the conceptual difficulty of defining a thermal dose. The NATO course was designed to provide a basis for the integration of physics and technology relevant to the development of hyperthermia. There were 48 lectures covering the theoretical and practical aspects of system design and assessment, including, as far as possible, all the techniques of current interest and importance in the field.

Book excerpt: Hyperthermia has been found to be of great benefit in combination with radiation therapy or chemotherapy in the management of patients with difficult and com plicated tumor problems. It has been demonstrated to increase the efficacy of ionizing radiation when used locally but also has been of help in combination with systemic chemotherapy where hyperthermia is carried out to the total body. Triple modality (thermo-chemo-radiotherapy) or other treatment combinations have not been fully evaluated and may demonstrate extended clinical applications in the future. Problems remain with regard to maximizing the effects of hyperthermia as they are influenced by a variety of external and intrinsic factors including bloodflow, microenvironment etc. While the previous volume has summarized more theoretical aspects of hyper thermia, i.e. biology, physiology and physics, the present volume compiles the current knowledge relative to the clinical applications of hyperthermia in combina tion with radiation therapy and/or chemotherapy, providing a comprehensive over view of its use in cancer management.
