Available in PDF, EPUB and Kindle. Book excerpt: Microwave ablation is one of the most common minimally invasive targeted cancer treatment technique. Since development phase of the technique resulted in several commercial ablation systems, current research topics include optimization of the current systems and practices. Recent studies have shown that outcomes of microwave ablation can vary patient to patient. To foresee the ablation results, investigation of treatment planning techniques has gained great interest recently. Simulations have been the main tool for the treatment planning process which requires accurate tissue models. In this work, I investigated new simulation approaches to increase microwave ablation simulation accuracy. Chapter 1 provides an introduction to the current state of microwave ablation and the variability of ablation outcomes with the current systems are presented. Potential sources of this variability were discussed. Moreover, the accuracy of microwave ablation simulations was evaluated with ex-vivo studies (experiments and simulations). The study results suggested that current dielectric property models need improvement. Therefore, following chapters focused on the dielectric tissue property model development for liver and lung tissues. In microwave ablation context, tissue properties can be divided into two groups: baseline and temperature dependent temporal changes during heating. Both depends on the constituents of tissues; therefore, dielectric mixture models were used in the development of liver and lung tissue models. Chapter 2 presents tissue models which were tissue water content dependent. It has been assumed that water content was responsible for the drastic changes in dielectric properties during heating. Chapter 3 outlines the techniques for application of the water content dependent dielectric mixture models in the microwave ablation setting. With this study, it was directly shown that vaporization was the most dominant mechanism in dielectric property change at high temperatures, dielectric mixture models can model vapor induced effects, and the proposed approach with the mixture model allowed more accurate dielectric property predictions than the current models in literature. Since this study focused the temporal changes of tissue properties. In the first 3 chapters, temporal changes in dielectric properties were studied. Chapter 4 presents experiments and simulations in phantoms for tissues with ectopic fat storage, which changes the baseline tissue properties. Differences in heating mechanisms in phantoms with varying fat contents were discovered. Moreover, a framework was introduced for imaging-based (magnetic resonance imaging) determination of baseline tissue dielectric properties. Chapter 5 describes lung tissue dielectric property models that have been built with the data that was collected. The aim of this study was to develop an air content tissue model for lung, therefore, concurrent measurements of dielectric properties with open-ended coaxial probe and air content with CT and microCT was included in the model development process. Chapter 6 describes the implementation of the tissue dielectric property model that was developed in the Chapter 2 and 3 in simulations. The results of the simulated ablation zones were compared with the ablation zones that were measured precisely by accounting for the contraction. The simulations with the proposed model had higher accuracy in the prediction of the ablation zone dimensions in ex-vivo tissues. Chapter 6 also included a study on thermal behavior of the liver perfusion. The literature review on perfusion in the thermal ablation area showed the need for a liver specific perfusion model. In-vivo liver ablation temperatures were collected and used as the training data for the optimization of a muscle perfusion model for liver tissue.
Download or read book Radiofrequency Ablation for Small Hepatocellular Carcinoma written by Minshan Chen and published by Springer. This book was released on 2015-11-26 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive guide to the treatment of small hepatocellular carcinoma (sHCC) using a minimally invasive technique: radiofrequency ablation (RFA). RFA has emerged as a new treatment modality and become the main modality of locoregional therapy. Extensive clinical research indicates that RFA is as effective as surgical resection for sHCC, and it has the advantage of being less invasive. However, the outcomes after RFA are largely dependent on the operators’ experience- known as the “learning curve”. This book presents the characteristics of sHCC and discusses why sHCC is the best candidate for RFA. Then it introduces all the commercially available RFA systems, and their working principles, advantages, disadvantages and so on. It goes on to demonstrate how to perform RFA under the guidance of ultrasound, CT, laparoscopy, or during open operation. Finally, it discusses the radiologic assessment and follow‐up after RFA, as well as adjuvant therapies and clinical trials on RFA. The authors are experts from the fields of pathology, radiology, surgery, and gastroenterology, as well as manufacturers. With this book, readers gain have a clear idea of when and how to do RFA. It aims to standardize and generalize the procedure of RFA, which will be very helpful in improving the outcome of RFA for sHCC.

Book excerpt: Lung cancer continues to be the leading cause of cancer mortality worldwide among both men and women. Recent advances in prevention, screening and management in the past decade have led to significant improvements in survival and quality of life. Local treatments like minimally invasive surgery, radiotherapy, and image-guided ablation have contributed to improving the effectiveness and tolerability of potentially curative treatments in early-stage, locally advanced, and oligometastatic/oligoprogressive disease. Chemotherapy, targeted therapy, immunotherapy, and palliative local therapy options have expanded rapidly, with new regimens showing improved outcomes even for those with widely metastatic disease. This book comprehensively reviews the evidence that has driven personalized medicine, based on a variety of multidisciplinary perspectives by international lung cancer experts.

Download or read book Tumor Ablation written by Eric van Sonnenberg and published by Springer Science & Business Media. This book was released on 2008-09-08 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is an enormous sense of excitement in the communities of cancer research and cancer care as we move into the middle third of the ?rst decade of the 21st century. For the ?rst time,there is a true sense of c- ?dence that the tools provided by the human genome project will enable cancer researchers to crack the code of genomic abnormalities that allow tumor cells to live within the body and provide highly speci?c, virtually non-toxic therapies for the eradication,or at least ?rm control of human cancers. There is also good reason to hope that these same lines of inquiry will yield better tests for screening, early detection, and prev- tion of progression beyond curability. While these developments provide a legitimate basis for much op- mism, many patients will continue to develop cancers and suffer from their debilitating effects, even as research moves ahead. For these in- viduals, it is imperative that the cancer ?eld make the best possible use of the tools available to provide present day cancer patients with the best chances for cure, effective palliation, or, at the very least, relief from symptoms caused by acute intercurrent complications of cancer. A modality that has emerged as a very useful approach to at least some of these goals is tumor ablation by the use of physical or physiochemical approaches.

Download or read book Irreversible Electroporation written by Boris Rubinsky and published by Springer Science & Business Media. This book was released on 2009-11-25 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-thermal irreversible electroporation is a new minimally invasive surgical p- cedure with unique molecular selectivity attributes – in fact it may be considered the first clinical molecular surgery procedure. Non-thermal irreversible electro- ration is a molecular selective mode of cell ablation that employs brief electrical fields to produce nanoscale defects in the cell membrane, which can lead to cell death, without an effect on any of the other tissue molecules. The electrical fields can be produced through contact by insertion of electrode needles around the undesirable tissue and non-invasively by electromagnetic induction. This new - dition to the medical armamentarium requires the active involvement and is of interest to clinical physicians, medical researchers, mechanical engineers, che- cal engineers, electrical engineers, instrumentation designers, medical companies and many other fields and disciplines that were never exposed in their training to irreversible electroporation or to a similar concept. This edited book is designed to be a comprehensive introduction to the field of irreversible electroporation to those that were not exposed or trained in the field before and can also serve as a reference manual. Irreversible electroporation is broad and interdisciplinary. Therefore, we have made an attempt to cover every one of the various aspects of the field from an introductory basic level to state of the art.

Download or read book Modern Cryosurgery For Cancer written by Kecheng Xu and published by World Scientific. This book was released on 2012-04-26 with total page 940 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cryosurgery is a surgical technique that employs freezing to destroy undesirable tissue. From as early as 3500 BC, there is evidence for the use of cold in medicine for the treatment of infected wounds of the chest, fracture of the skull and various injuries. However, the history of “modern” cryosurgery is relatively short and is closely intertwined with the development in low temperature physics, engineering, and instrumentation during the last century.From the early 21st century, advanced helium-based cryosurgery has been applied worldwide. More than ten thousand patients with malignant and benign tumors have received cryosurgery. It is specially noted that in most cases cryosurgery, as a mini-invasive ablation technique, was performed with percutaneous approach under guidance of CT or ultrasound. Cryosurgery is now one of the more popular techniques in China, with nearly 6000 cases of tumors receiving cryosurgery in the author's institution alone. This book summarizes the experimental and clinical experience and practice of cryosurgery, and describes the basics of cryosurgery and its use in the treatment of various tumors.
