Comparative Study Controlled Clinical TrialComparison of RECIST, EORTC criteria and PERCIST for evaluation of early response to chemotherapy in patients with non-small-cell lung cancer.
To compare the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, the European Organization for Research and Treatment of Cancer (EORTC) criteria and the Positron Emission Tomography Response Criteria in Solid Tumors (PERCIST) 1.0 using PET volume computer-assisted reading (PET VCAR) for response evaluation in patients with advanced non-small-cell lung cancer (NSCLC) treated with chemotherapy. ⋯ EORTC criteria and PERCIST 1.0 are more sensitive and accurate than RECIST 1.1 for the detection of an early therapeutic response to chemotherapy in patients with NSCLC. Although EORTC criteria and PERCIST 1.0 showed similar results, PERCIST 1.0 is preferred because detailed and unambiguous definitions are given. We also found that response evaluations with PERCIST 1.0 using a single lesion and multiple lesions gave similar response classifications.
