JO - Cancers VL - 12 IS - 9 SN - 2072-6694 CY - Basel PB - MDPI M1 - DKFZ-2020-01839 SP - 2537 PY - 2020 N1 - #EA:E010# AB - The purpose of this study was to assess how different MRI protocols (spinal vs. spinal plus pelvic vs. whole-body (wb)-MRI) affect staging in patients with smoldering multiple myeloma (SMM), according to the SLiM-CRAB-criterion '>1 focal lesion (FL) in MRI'. In this retrospective study, a baseline cohort of 147 SMM patients with wb-MRI at initial diagnosis was investigated, including prognostic data regarding development of CRAB-criteria. Fifty-two patients formed a follow-up cohort with a median of three wb-MRIs. The locations of all FLs were determined and it was calculated how staging decisions regarding the criterion '>1 FL in MRI' would have been made if only a limited anatomic area (spine vs. spine plus pelvis) would have been covered by the MRI protocol. Furthermore, subgroups of patients selected by different cutoff-protocol-combinations were compared regarding their prognosis for development of CRAB-criteria. With an MRI protocol limited to spine/spine plus pelvis, only 28 LB - PUB:(DE-HGF)16 C6 - pmid:32906608 DO - DOI:10.3390/cancers12092537 UR - https://inrepo02.dkfz.de/record/163053 ER -
