Response Evaluation Criteria In Solid Tumors

Response Evaluation Criteria in Solid Tumors (RECIST) are standardized guidelines used by doctors to measure how well a cancer treatment is working. They assess changes in the size of tumors through imaging tests like CT or MRI scans. By comparing tumor size before and after treatment, RECIST helps determine if the cancer is shrinking (responding), staying the same (stable), or growing (progressing). This consistent method allows healthcare providers to make informed decisions about the effectiveness of therapies and plan appropriate patient care.
