Radiotherapy for Non-Malignant Disorders


Book Description

This volume discusses the background and various clinical applications of radiation therapy in the treatment of non-malignant diseases. It documents the radiobiological and physical principles of treatment and the rationale underlying the use of radiotherapy for various disorders of the CNS, head and neck, eye, skin and soft tissues, bone and joints, and vascular system. In so doing, it draws attention to and elucidates the scope for application of radiotherapy beyond the treatment of malignancies. Both the risks and the benefits of such treatment are fully considered, the former ranging from minor clinical problems to life-threatening diseases.




The Radiotherapy of Malignant Disease


Book Description

Radiotherapy or radiation therapeutics, as the name suggests, is a branch of general therapeutics. In this case the therapeutic agent is ionising radiation which induces specific and predictable biological changes. Radiotherapy is sometimes described as therapeutic radiology because historically the earliest X-ray machines were used both for diagnostic and therapeutic purposes. Diagnostic radiology has since become a very complex and time-consuming speciality requiring the undivided care and attention of the diagnostic radiologist. Similarly, radiotherapy now embraces both X-ray beams and the radiations from radium and various artificial radium substitutes. This too requires the full-time attention of the radiotherapist. In recent years radiotherapy has sometimes been described as radiotherapeutic oncology, to indicate the involvement of the radiotherapist in oncological management and indeed in all aspects of oncology from prevention and early detection to the treatment, after-care, and (for those who need it) terminal care of the patient. The radiotherapist, by total commitment to the cancer problem, is in truth the epitome of the oncologist. In the same way as the medical physician or internist requires a proper understanding of the pharmacology of the therapeutic agents he or she employs-the nature, metabolic biochemistry, and biological effects of any administered drug-so also the radiotherapist needs to understand the nature, biological effects, and therapeutic potentialities of ionising radiations. The radiotherapist's "pharmacology" involves an understanding of the relevant physics and radiobiology.




Targeted Radionuclide Therapy


Book Description

Radioimmunotherapy, also known as systemic targeted radiation therapy, uses antibodies, antibody fragments, or compounds as carriers to guide radiation to the targets. It is a topic rapidly increasing in importance and success in treatment of cancer patients. This book represents a comprehensive amalgamation of the radiation physics, chemistry, radiobiology, tumor models, and clinical data for targeted radionuclide therapy. It outlines the current challenges and provides a glimpse at future directions. With significant advances in cell biology and molecular engineering, many targeting constructs are now available that will safely deliver these highly cytotoxic radionuclides in a targeted fashion. A companion website includes the full text and an image bank.




Health Risks from Exposure to Low Levels of Ionizing Radiation


Book Description

This book is the seventh in a series of titles from the National Research Council that addresses the effects of exposure to low dose LET (Linear Energy Transfer) ionizing radiation and human health. Updating information previously presented in the 1990 publication, Health Effects of Exposure to Low Levels of Ionizing Radiation: BEIR V, this book draws upon new data in both epidemiologic and experimental research. Ionizing radiation arises from both natural and man-made sources and at very high doses can produce damaging effects in human tissue that can be evident within days after exposure. However, it is the low-dose exposures that are the focus of this book. So-called “late” effects, such as cancer, are produced many years after the initial exposure. This book is among the first of its kind to include detailed risk estimates for cancer incidence in addition to cancer mortality. BEIR VII offers a full review of the available biological, biophysical, and epidemiological literature since the last BEIR report on the subject and develops the most up-to-date and comprehensive risk estimates for cancer and other health effects from exposure to low-level ionizing radiation.




Childhood Cancer and Functional Impacts Across the Care Continuum


Book Description

Since the late 1960s, the survival rate in children and adolescents diagnosed with cancer has steadily improved, with a corresponding decline in the cancer-specific death rate. Although the improvements in survival are encouraging, they have come at the cost of acute, chronic, and late adverse effects precipitated by the toxicities associated with the individual or combined use of different types of treatment (e.g., surgery, radiation, chemotherapy). In some cases, the impairments resulting from cancer and its treatment are severe enough to qualify a child for U.S. Social Security Administration disability benefits. At the request of Social Security Administration, Childhood Cancer and Functional Impacts Across the Care Continuum provides current information and findings and conclusions regarding the diagnosis, treatment, and prognosis of selected childhood cancers, including different types of malignant solid tumors, and the effect of those cancers on childrenâ (TM)s health and functional capacity, including the relative levels of functional limitation typically associated with the cancers and their treatment. This report also provides a summary of selected treatments currently being studied in clinical trials and identifies any limitations on the availability of these treatments, such as whether treatments are available only in certain geographic areas.




Selected Health Conditions and Likelihood of Improvement with Treatment


Book Description

The Social Security Administration (SSA) administers two programs that provide disability benefits: the Social Security Disability Insurance (SSDI) program and the Supplemental Security Income (SSI) program. SSDI provides disability benefits to people (under the full retirement age) who are no longer able to work because of a disabling medical condition. SSI provides income assistance for disabled, blind, and aged people who have limited income and resources regardless of their prior participation in the labor force. Both programs share a common disability determination process administered by SSA and state agencies as well as a common definition of disability for adults: "the inability to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months." Disabled workers might receive either SSDI benefits or SSI payments, or both, depending on their recent work history and current income and assets. Disabled workers might also receive benefits from other public programs such as workers' compensation, which insures against work-related illness or injuries occurring on the job, but those other programs have their own definitions and eligibility criteria. Selected Health Conditions and Likelihood of Improvement with Treatment identifies and defines the professionally accepted, standard measurements of outcomes improvement for medical conditions. This report also identifies specific, long-lasting medical conditions for adults in the categories of mental health disorders, cancers, and musculoskeletal disorders. Specifically, these conditions are disabling for a length of time, but typically don't result in permanently disabling limitations; are responsive to treatment; and after a specific length of time of treatment, improve to the point at which the conditions are no longer disabling.




Metronomic Chemotherapy


Book Description

This book analyzes all aspects of metronomic chemotherapy, a new approach involving low-dose, long-term, and frequently administered therapy that has preclinical and clinical activity in various tumors. After an opening section on the pharmacological bases of metronomic chemotherapy, including its antiangiogenic effects and impact on immunity, preclinical studies on various classes of drug are discussed. Clinical applications of metronomic chemotherapy in a wide variety of tumors are then addressed in detail, with description of the results of all published studies. The clinical pharmacology of metronomic chemotherapy is also considered in depth, encompassing pharmacokinetics, pharmacogenetics, pharmacoeconomics, and adverse drug reactions. The book closes by describing the role of this therapy in the veterinarian clinic.
