Accelerated Partial Breast Irradiation
Author: David E. Wazer
Publisher: Springer Science & Business Media
ISBN: 3540880062
Category : Medical
Languages : en
Pages : 447
Book Description
Accelerated partial breast irradiation (APBI) is being rapidly introduced into the clinical management of early breast cancer. APBI, in fact, encompasses a number of different techniques and approaches that include brachytherapy, intraoperative, and external beam techniques. There is currently no single source that describes these techniques and their clinical implementation. This text is a concise handbook designed to assist the clinician in the implementation of APBI. This includes a review of the principles that underlie APBI, a practical and detailed description of each technique for APBI, a review of current clinical results of APBI, and a review of the incidence and management of treatment related complications.

Radiotherapy in Cancer Care
Author: International Atomic Energy Agency
Publisher:
ISBN: 9789201150134
Category : Medical
Languages : en
Pages : 544
Book Description
Cancer treatment is complex and calls for a diverse set of services. Radiation therapy is recognized as an essential tool in the cure and palliation of cancer. Currently, access to radiation treatment is limited in many countries and non-existent in some. This lack of radiation therapy resources exacerbates the burden of disease and underscores the continuing health care disparity among States. Closing this gap represents an essential measure in addressing this global health equity problem. This publication presents a comprehensive overview of the major topics and issues to be taken into consideration when planning a strategy to address this problem, in particular in low and middle income countries. With contributions from leaders in the field, it provides an introduction to the achievements and issues of radiation therapy as a cancer treatment modality around the world. Dedicated chapters focus on the new radiotherapy technologies, proton beams, carbon ion, intraoperative radiotherapy, radiotherapy for children, treatment of HIV-AIDS malignancies, and costing and quality management issues.

This book explores outcome modeling in cancer from a data-centric perspective to enable a better understanding of complex treatment response, to guide the design of advanced clinical trials, and to aid personalized patient care and improve their quality of life. It contains coverage of the relevant data sources available for model construction (panomics), ranging from clinical or preclinical resources to basic patient and treatment characteristics, medical imaging (radiomics), and molecular biological markers such as those involved in genomics, proteomics and metabolomics. It also includes discussions on the varying methodologies for predictive model building with analytical and data-driven approaches. This book is primarily intended to act as a tutorial for newcomers to the field of outcome modeling, as it includes in-depth how-to recipes on modeling artistry while providing sufficient instruction on how such models can approximate the physical and biological realities of clinical treatment. The book will also be of value to seasoned practitioners as a reference on the varying aspects of outcome modeling and their current applications. Features: Covers top-down approaches applying statistical, machine learning, and big data analytics and bottom-up approaches using first principles and multi-scale techniques, including numerical simulations based on Monte Carlo and automata techniques Provides an overview of the available software tools and resources for outcome model development and evaluation, and includes hands-on detailed examples throughout Presents a diverse selection of the common applications of outcome modeling in a wide variety of areas: treatment planning in radiotherapy, chemotherapy and immunotherapy, utility-based and biomarker applications, particle therapy modeling, oncological surgery, and the design of adaptive and SMART clinical trials

Toxicities of Radiation Treatment for Breast Cancer
Author: Jean L. Wright
Publisher: Springer
ISBN: 3030116204
Category : Medical
Languages : en
Pages : 206
Book Description
This book is a comprehensive guide to breast toxicity. Adjuvant radiation remains standard for a majority of women who undergo breast-conserving surgery for breast cancer, and indications for post-mastectomy and regional lymph node irradiation have also broadened with recent publications. At the same time, locoregional recurrence has declined and survival has improved in recent decades. In the current era of excellent breast cancer outcomes, then, considering the balance between toxicity and outcomes becomes paramount. Several recent editorials recommend considering toxicity against the potential benefit of adjuvant radiation in tailoring radiation decisions for individual patients. Thus, a clear understanding of the potential toxicities of adjuvant radiation for breast cancer is critical to optimizing outcomes in modern breast cancer management. Here, authors have collected recent data focused on toxicity of treatment that provide an opportunity for improving this optimization. Chapters cover both acute and late toxicity of radiation for breast cancer, including tailored risk assessment for each of these potential toxicities, considerations for including risk of toxicity in management decisions, and toxicity management strategies. This is an ideal guide for radiation oncologists, residents, and oncologists seeking to optimize care for their patients.
