These sufferers are viewed as to have achieved a minimal residual disease (MRD) unfavorable status.17-20 Several phase II trials have [http://www.medchemexpress.com/Betulin.html Trochol solubility] demonstrated that patients reaching MRD negativity have a signif-icantly longer survival than people that remain MRD optimistic, and this can be true for individuals treated with traditional chemotherapy,21,22 monoclonal antibodies,23 chemoimmunotherapy,24 or stem cell transplantation.25,26 Furthermore, a phase III trial performed by the German CLL Study Group (GCLLSG) lately revealed that patients acquiring MRD negativity had significantly longer progression-free and general survivals, irrespectively of the treatment received.18 Unfortunately, nonetheless, some of these research were flawed by inappropriate statistical analysis, especially the measurement of time-to-event outcomes from therapy initiation.27 In addition, there are several caveats towards the use of MRD analysis in individuals with CLL.28 1st, CLL remains incurable and at least 30  of patients who obtain MRD negativity soon after front-line therapy with fludarabine-cyclophosphamide (FC) or rituximab-FC ultimately expertise a illness relapse inside five years.18 Secondly, in contrast to the situation in acute promyelocytic leukemia or chronic myeloid leukemia,29,30 there is no formal proof of a therapeutic benefit of re-treatment upon documentation of MRD positivity following an initial MRD-negative response compared to treatment at the time of clinical relapse.
