Locoregional High-Frequency Hyperthermia and Temperature Measurement by G. Bruggmoser,W. Hinkelbein,R. Engelhardt,M. Wannenmacher Pdf

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.

Oncothermia: Principles and Practices by Andras Szasz,Nora Szasz,Oliver Szasz Pdf

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.

Hyperthermia and the Therapy of Malignant Tumors by Christian Streffer Pdf

Tumour therapy depends essentially on being able to destroy the clonogenic activity of tumour cells while keeping the damage to the normal tissue low. Clinical experience shows that tumour response varies greatly even if tumours with the same localisation, clinical, and histopathological staging are compared. Some tumours appear to be resistant to conventional radiotherapy (X-rays, y-rays or fast electrons) or chemotherapy. In these cases new therapy modalities are necessary. Combined therapy modalities seem to have advan tages for some resistant tumours; one possibility of such a treatment is to combine radiotherapy or chemotherapy with hyperthermia. This means that the local tumour, the tumour region or even the whole body of the patient has to be heated to temperatures between 40° to 45° C (in case of whole body hyperthermia to 42° C maximal) for a certain time (usually 30-60 min are adequate). Hyperthermia has a long tradition in medicine as a treatment modality for various diseases. Inscriptions of the old Egyptians and texts of the Greeks have pointed out its importance. Usually whole body hyperthermia has been used by the induction of fever. Local hyperthermia began around 1900 when Westermark treated unre sectable cervix carcinomas with hot water in a metallic coil. By the beginning of this century an increase of radiation effects was hy pothesised with hypothermia and later observed. However, only in the 1960s and 1970s were systematic investigations started which showed radiosensitisation and chemosensitisation by hyperthermia in cells and tissues including tumours.

Breast Cancer by Sam Brünner,Bent Langfeldt Pdf

The Third International Copenhagen Symposium on Detection of Breast Cancer afforded a further opportunity for scientists from all over the world to come together and present important papers con cerning breast cancer and early diagnostic procedures. The Sympo sium was an opportunity to learn from extensive screening proce dures carried out at outstanding centers in the United States, Sweden, the Netherlands, and England. Furthermore, the Sympo sium dealt with new modalities such as ultrasonography, magnifi cation techniques, and magnetic resonance; and very important contributions concerning self-examination, fine needle aspiration biopsy, and radiation risks were presented. A whole section was also dedicated to the highly important cooperation between radiologist, surgeon, and pathologist. It is our sincere hope that a study of the different aspects of breast cancer presented in this volume will encourage the reader to join in the struggle against this dreadful dis ease.

Minimal Neoplasia by Ekkehard Grundmann,Lutwin Beck Pdf

Minimal neoplasia may be defined as a small cancer that has progressed beyond its site of primary origin into the surrounding tissue, but that has not yet reached the stage of deeper invasion or metastasization. The basic principles of this minimal cancer are presented in chapters on molecular, biological and experimental aspects, and, in particular, on the clinical manifestations in various organs: preleukemia, incipient lymphoma, and minimal carcinomas of the uterine cervix, breast, thyroid, larynx, lung, prostate, stomach and colon. A separate chapter is devoted to cryptic gliomas. The latest morphological methods including cytology, early clinical diagnostics and, in particular, radiodiagnostics, are considered. The reader can expect up-to-date information about prompt diagnosis of the very early manifestations of cancer, together with inferences on therapy, which, especially in tumors of the uterine cervix, breast and thyroid, differs considerably from the treatment of advanced neoplasia.

Thermal Dosimetry and Treatment Planning by Michel Gautherie Pdf

When in the future improved and more flexible heating equipment becomes available, and when hyperthermia is applied more routinely, computerized simulations of treatments will become commonplace, as they are in radia tion therapy. For hyperthermia, however, such simulations will be used not only for the traditional role of planning patient treatment, but also for three other applications not needed in radiation therapy - the comparative evalu ation of equipment, feedback control during treatment, and the post-treat ment evaluation of therapy. The present simulations of hyperthermia are crude and simple when compared with what is required for these future ap plications, a fact which indicates the nedd for considerable research and de velopment in this area. Indeed, this research is proceeding rapidly within the hyperthermia community, whre three-dimensional power deposition and temperature calculations have just become available for realistic patief\t anatomies. Of equal significance are the even more rapid development in diagnostic imaging for the determination and display of patient anatomy and blood flow rates - information required for the planning of realistic hyperthermia treatment. These simulations will be very valuable tools which can be used to great ad vantage when combined with data obtained from treatments of patients.

Preoperative (Neoadjuvant) Chemotherapy by Joseph Ragaz,Pierre R. Band,James H. Goldie Pdf

Despite recent advances in adjuvant therapies of cancer, the regi mens of postoperative adjuvant chemotherapy treatment which are presently available fail to cure the majority of cancer patients. Pre operative (neoadjuvant) chemotherapy represents a new approach in drug scheduling, based on sound theoretical, pharmacokinetic, and experimental principles. The preoperative timing of chemotherapy before definitive sur gery is not a minor change in the therapy of cancer. To be successful, large numbers of practitioners and their patients must participate. Substantial alterations of many aspects of the present management of cancer will have to follow. Therefore, before such therapy can be fully and routinely implemented, results of the novel treatment and its rationale have to be carefully evaluated. In preoperative treatment, other features will likely gain impor tance. For the first time, clinicians have a chance to follow the in vivo response of the tumor exposed to preoperative chemotherapy. The subsequent histological assessment of the tumor sample may likely become an important prognostic guide, permitting more re fined individual approaches to the planning of postoperative adju vant treatment. The value of such a treatment strategy can already be appreciated in the clinical setting, as seen from the therapy of osteosarcoma. Furthermore, preoperative chemotherapy might render previously inoperable tumors operable and hence resectable with a curative intention. The preoperative reduction of tumor bulk may also effectively decrease the need for more radical operations, permitting a more uniform adoption of conservative surgery.

Thermoradiotherapy and Thermochemotherapy by M.Heinrich Seegenschmiedt,Peter Fessenden,Clare C. Vernon Pdf

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.

Interstitial, Endocavitary and Perfusional Hyperthermia by Michel Gautherie Pdf

"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.

Epidemiology of Malignant Melanoma by Richard P. Gallagher Pdf

Interest in the etiology of malignant melanoma has increased enor mously in the last 10 years, after it was realized that the incidence of the cutaneous form of the disease was rising. Treatment of the disease has not improved dramatically, and our best hope for curtailing the rise in mortality and morbidity from the disease appears to be primarily through early detection and, per haps in the future, through prevention. It is thus very important for the medical community to be able to recognize individuals and groups at high risk of the disease because of either familial and con stitutional factors and lifestyle or exposure to environmental risk factors. This book, arising from a meeting held in Vancouver in 1984, pro vides a summary of the latest findings amo ~ Caucasian popula tions along with perspectives on the most im, Jrtant environmental risk factors identified to date. Comparison of results from the four major analytic studies presented here also demonstrates that a num ber of factors implicated in other common cancers are probably not related to the incidence of melanoma. These include smoking, alco hol consumption, and for the most part, diet. The Vancouver conference was sponsored by the Cancer Control Agency of British Columbia, and was financially supported by Health and Welfare Canada (6610-1429-50), the Northern Califor nia Cancer Program (NCCP), Miles Laboratories (Canada), Bristol Myers Laboratories (Canada), and Plough Canada Inc.
