CONTRADICTING EVIDENCE: FCR and FCM-R...PFS by pre-treatment prognostic factors revealed unmutated IGHV genes (UM-IGHV), 17p/11q deletion, TP53 mutations, CLL-IPI, %CD38+ cells, decreasing CD20 mean fluorescence intensity (MFI), %CD49d+ cells, CCR6 (MFI and %+ cells) and LAIR1 MFI to be associated with shortened PFS....A multivariable analysis of prognostic factors and MRD reveals the key prognostic factors for shortened OS to be age, MRD, d17p/TP53 mutation and CD49d.
