Full Definition
RECIST (Response Evaluation Criteria in Solid Tumors) criteria are internationally accepted guidelines used to assess how well cancer treatments work by measuring changes in tumor size. These criteria provide standardized definitions for complete response, partial response, stable disease, and progressive disease based on imaging studies. RECIST criteria ensure consistency in response assessment across different clinical trials and institutions, facilitating comparison of treatment outcomes and regulatory approval processes.
