Abstract:
Response Evaluation Criteria in Solid Tumors (RECIST), including version 1.0 and 1.1, has been universally accepted as the standard response assessment criteria for conventional chemotherapies. Increasing use of immunotherapy led to the need and development of immune-related RECIST. Imaging plays a crucial role in response assessment for solid tumors in guiding patient management as well as in clinical trials. Familiarity to different response criteria will help radiologists to optimally identify, select, and measure tumor lesions per the criteria and assess response to therapy. This article provides a comprehensive review of published RECIST criteria.
