How to perform RECIST measurements?
RECIST (Response Evaluation Criteria in Solid Tumors) measurements are commonly used to assess tumor response to treatment in clinical trials and practice. To perform RECIST measurements, first identify the target lesions and measure their longest diameter using imaging modalities such as CT or MRI. Take measurements at the same location and with the same imaging technique over time for accurate comparison. When measuring non-nodal lesions, a minimum of 10 mm in longest diameter is considered measurable, while lymph nodes must have a longest diameter of at least 15 mm to be considered measurable. Consult the RECIST guidelines for specific criteria and instructions on performing these measurements accurately.
