The Osler Institute utilized state of the art equipment to record our Live May 2018 comprehensive Radiation Oncology Review Course and bring it to you! These video files are stored “in the cloud” so you can stream them anywhere, anytime, as long as you have an internet connection. This review provides senior trainees and/or clinicians in practice a comprehensive update of clinical knowledge and helps prepare them for their Radiation Oncology exams (initial certification and MOC). Emphasis is on evidence-based medicine and board-relevant standards of care as well as new concepts, treatments, and imaging approaches. The written exams emphasize anatomy, epidemiology, etiological agents, natural history, pathology, tumor markers, initial clinical evaluation, staging, routes of spread, selection of treatment modality and techniques, surgical and chemotherapy adjuvant treatments, follow-up treatment and evaluation, patterns of failure, and normal tissue effects including complications; all of these areas were addressed in the recorded course. The review also covers the basic principles of radiobiology and physics that are relevant to clinical practice. Included with each Online review is an electronic downloadable copy of the syllabus that corresponds to the Video/Audio lectures.
