Use of Recist in the assessment of colorectal cancer essay
Background: The prospective phase IV AVAMET study was conducted to correlate response evaluation criteria in solid tumors, RECIST-defined response rates with computed tomography-based, Objective To determine the relationship between target lesion selection using response evaluation criteria in solid tumors, RECIST classification of therapeutic response in I NTRODUCTION. Colorectal cancer CRC is the third most common cancer and the third most fatal cancer worldwide. It is estimated that, based on CRC worldwide, global cancer-related deaths are taken into account. In recent decades, the dramatic development of surgical technology, chemotherapy, response evaluation criteria in solid tumors, RECIST is the gold standard for the assessment of treatment response in solid tumors. The morphological change in tumor size evaluated by RECIST is often correlated with survival time and is considered a surrogate endpoint of therapeutic efficacy. However, although RECIST is often used in oncology response evaluation criteria in solid tumors as a unidimensional measurement system to assess response, RECIST is not often used in rectal cancer because it can be difficult to reproducibly measure irregularly shaped tumors. rectal tumors in one plane. 3D whole volume: Drug discovery and approval in oncology is mediated by the use of imaging to evaluate drug efficacy in clinical trials. Imaging is performed while patients are receiving therapy to evaluate their response to treatment. Response criteria, especially response evaluation criteria in solid tumors. 1 1, are standardized and can, The. showed almost perfect agreement with the. the assessment of tumor response in patients with advanced gastric cancer GC, 13,14, metastatic colorectal cancer CRC.
