NovalisĀ® Shaped Beam Radiosurgery has set new standards by delivering highly precise radiation treatments to tumors anywhere in the body through the use of a proprietary multileaf collimator. By shaping the radiation beam to the exact contours of the tumor or lesion, Novalis permits maximum dose delivery to the entire tumor while protecting healthy tissue; this makes it eminently suitable for the treatment of irregularly shaped tumors. This book provides a complete guide to radiosurgery treatments with Novalis. After a thorough discussion of the clinical and technical basis for Shaped Beam Radiosurgery, current clinical applications are considered in detail, including brain, body, skull base, and spinal tumors as well as arteriovenous malformations. Careful consideration is also given to future developments and applications, including new technologies that promise to offer even more accurate treatments. This state-of-the-art book will appeal to a wide audience of physicians and their multidisciplinary clinical and technical collaborators.
Modern Radiotherapy (RT) plays a key role in the management of Head and Neck Cancer (HNC). More precise delivery techniques, advanced image-guidance, and adaptive treatments characterize modern RT, enabling safer treatments with enhanced therapeutic window. Although patients identify the cure as their most important treatment outcome, complications related to treatment are a recognized problem as follow-up increases among those cured within this oncologic setting. This is particularly relevant for HPV-related oropharyngeal cancer (OPSCC), as these patients are younger, healthier, and more reactive to treatment. Thus, given the longer life expectancy, the jeopardizing impact of side effects on quality of life (QoL) and psychosocial functioning represent a forefront topic for HNC Researchers. De-escalation protocols have been developed recently, and, although not definitive, evidence is growing. This pertains particularly, but not exclusively, to HPV-related OPSCC.
This book provides novel perspectives on ethical justifiability of assisted dying in the revised edition of New Directions in the Ethics of Assisted Suicide and Euthanasia. Going significantly beyond traditional debates about the value of human life, the ethical significance of individual autonomy, the compatibility of assisted dying with the ethical obligations of medical professionals, and questions surrounding intention and causation, this book promises to shift the terrain of the ethical debates about assisted dying. The novel themes discussed in the revised edition include the role of markets, disability, gender, artificial intelligence, medical futility, race, and transhumanism. Ideal for advanced courses in bioethics and healthcare ethics, the book illustrates how social and technological developments will shape debates about assisted dying in the years to come.
Stereotactic body radiation therapy (SBRT) has emerged as an important innovative treatment for various primary and metastatic cancers. This book provides a comprehensive and up-to-date account of the physical/technological, biological, and clinical aspects of SBRT. It will serve as a detailed resource for this rapidly developing treatment modality. The organ sites covered include lung, liver, spine, pancreas, prostate, adrenal, head and neck, and female reproductive tract. Retrospective studies and prospective clinical trials on SBRT for various organ sites from around the world are examined, and toxicities and normal tissue constraints are discussed. This book features unique insights from world-renowned experts in SBRT from North America, Asia, and Europe. It will be necessary reading for radiation oncologists, radiation oncology residents and fellows, medical physicists, medical physics residents, medical oncologists, surgical oncologists, and cancer scientists.
This book, written by leading international experts, describes alternate fractionation strategies in which technology-driven precise targeting and dosing allow for improved conformance and decreased volumes, with concordant lessening of toxicity, reduction in treatment time, and lower overall health care expense. The aim is to provide the advanced clinician with an up-to-date evidence-based reference that will assist in the delivery of enhanced patient care in daily practice. Traditional multi-week fractionation schedules were established at a time when the inclusion of relatively large amounts of normal tissue was unavoidable owing to the lack of accurate target localization during treatment. Such schedules are time and resource consuming, difficult for patients, and expensive. Nevertheless, acceptance of alternate fractionation strategies has been slow in some countries. The paradigm is, however, changing as evidence accumulates to demonstrate improved local control, equivalence of tolerance, or both. In documenting these alternate strategies, this book will be of value for radiation oncologists, medical physicists, and oncologists worldwide.
This book is a comprehensive review of stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT): its physics, clinical evidence, indications, and future directions. The utilization of stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT) is increasing internationally because of several factors. First, it offers patients a local treatment option that has demonstrated effectiveness similar to traditional surgery without the morbidity of general anesthesia and open surgical resection. Second, recent advancements in the quality of scientific evidence supporting a SRS or SBRT-containing approach in patients continues to evolve and demonstrate favorab...
Hepatocellular carcinoma (HCC) is a leading cause of death globally. Conventional chemotherapeutic agents are unable to penetrate cancerous hepatocytes completely and are toxic to non cancerous cells and tissues. This toxicity significantly compromises the therapeutic outcome of conventional chemotherapeutic agents which is also reflected in the high mortality of the disease. Nanotherapeutics have shed new light onto HCC treatment by enabling site-specific in vivo delivery of chemotherapeutics specifically to neoplastic hepatocytes without affecting normal hepatocytes. Thus, nanotherapeutics have shown considerable potential and there is tremendous impetus for rapid translation from the pre-...
Oligometastatic disease represents an intermediate state between the early localized disease and widespread metastatic malignancy. Some patients with oligometastatic disease, treated by ablative therapies to all sites of metastatic disease, can achieve long disease-free survival and sometimes cure. Stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT) are accepted treatment options for these patients, achieving high rates of local control. While most of the studies report outcomes of SBRT for solitary oligometastasis, patients with oligometastatic disease might present with multiple concurrent lesions either in the same organ or in neighboring organs. There are few s...
