This handbook concisely summarizes state-of-the-art information about stereotactic radiosurgery (SRS) and stereotactic body radiotherapy (SBRT), including the history and development of these modalities, the biologic rationale for these technologies, typical practices, and reported results. Developed as a companion to Handbook of Evidence-Based Radiation Oncology, Second Edition, edited by Eric Hansen and Mack Roach, III, it is organized by disease site and presents treatment techniques and recommended imaging; safety and quality assurance; toxicities and management; recommended follow-up; and supporting evidence. Inclusion of evidence-based guidelines is intended to help inform decisions regarding the appropriateness of SRS and SBRT and guide treatment and evaluation. Handbook of Evidence-Based Stereotactic Radiosurgery and Stereotactic Body Radiotherapy can be easily referenced in the clinic and is a valuable guide for oncology practitioners.
