Prostate cancer is the most common cancer among North American and European men but its treatment continues to be problematic owing to serious side-effects, including erectile dysfunction and urinary incontinence. Robotic radiosurgery offers a novel, rapid, non-invasive outpatient treatment option for prostate cancer that combines robotics, advanced image-guided spatial positioning, and motion detection with submillimeter precision. This book examines all aspects of the treatment of prostate cancer with robotic radiosurgery. After introductory sections on radiosurgery as a multidisciplinary practice and specific issues relating to prostate cancer, the important challenge posed by patient motion when administering radiation therapy is examined in depth. Image-guided robotic radiosurgery overcomes this problem by continuously identifying the precise location of the prostate tumor throughout the course of treatment. A further major section is devoted to hypofractionated radiation delivery by means of robotic radiosurgery systems, which is regarded as more effective than conventional external beam fractionation. The book closes by discussing other emerging genitourinary applications of robotic radiosurgery. All of the authors are experts in their field who present a persuasive case for this fascinating technique.
