Abstrakt:	Purpose To investigate Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) approximations of target lesion tumor burden by comparing categorical treatment response according to conventional RECIST versus actual tumor volume measurements of RECIST target lesions. Materials and Methods This is a retrospective cohort study of individuals with metastatic renal cell carcinoma enrolled in a clinical trial (from 2003 to 2017) and includes individuals who underwent baseline and at least one follow-up chest, abdominal, and pelvic CT study and with at least one target lesion. Target lesion volume was assessed by (a) V model , a spherical model of conventional RECIST 1.1, which was extrapolated from RECIST diameter, and (b) V actual , manually contoured volume. Volumetric responses were determined by the sum of target lesion volumes (V model -sum TL and V actual -sum TL, respectively). Categorical volumetric thresholds were extrapolated from RECIST. McNemar tests were used to compare categorical volume responses. Results Target lesions were assessed at baseline (638 participants), week 9 (593 participants), and week 17 (508 participants). V model -sum TL classified more participants as having progressive disease (PD), compared with V actual -sum TL at week 9 (52 vs 31 participants) and week 17 (57 vs 39 participants), with significant overall response discordance ( P < .001). At week 9, 25 (48%) of 52 participants labeled with PD by V model -sum TL were classified as having stable disease by V actual -sum TL. Conclusion A model of RECIST 1.1 based on a single diameter measurement more frequently classified PD compared with response assessment by actual measured tumor volume.
