These sufferers are considered to have accomplished a minimal residual illness (MRD) adverse status.17-20 Several phase II trials have demonstrated that individuals reaching MRD negativity possess a signif-icantly longer survival than people that stay MRD optimistic, and this is true for patients treated with standard chemotherapy,21,22 monoclonal antibodies,23 chemoimmunotherapy,24 or stem cell transplantation.25,26 In addition, a phase III trial performed by the German CLL Study Group (GCLLSG) lately revealed that individuals acquiring MRD negativity had considerably longer progression-free and general survivals, irrespectively on the remedy received.18 Sadly, nonetheless, a few of these research had been flawed by inappropriate statistical analysis, specifically the measurement of time-to-event outcomes from therapy initiation.27 Furthermore, there are several caveats for the use of MRD analysis in sufferers with CLL.28 1st, CLL remains incurable and at the very least 30  of sufferers who reach MRD negativity soon after front-line therapy with fludarabine-cyclophosphamide (FC) or rituximab-FC at some point encounter a disease relapse inside 5 years.18 Secondly, unlike the predicament in acute promyelocytic leukemia or chronic myeloid leukemia,29,30 there is no formal proof of a therapeutic advantage of re-treatment upon documentation of MRD positivity following an initial MRD-negative response in comparison with remedy in the time of clinical relapse. The truth is, really handful of research have demonstrated a clear benefit from MRD eradication or consolidation therapy in CLL,31,32 and a few of the methods tested, although successful, resulted in considerable toxicity.33-35 Thirdly, it may be argued that MRD assessment is simply a surrogate for evalution of other adverse prognostic markers since, for example, sufferers having a 17p014 Ferrata Storti Foundation. That is an open-access paper. doi:10.3324/haematol.2013.099796 The on line version of this article features a Supplementary Appendix. Manuscript received on October 17, 2013.
