After many years of promise but little reward generic betnovate 20 gm line, many other immunotherapeutic approaches are now in transition to the clinical setting buy 20 gm betnovate overnight delivery. Clinical trials including CLL vaccines, CXCR4 antagonists, and adoptive cellular immunotherapies such as chimeric antigen receptor–modified T cells, CD40 ligand gene therapy, and the immunomodulatory drug lenalidomide are ongoing. Results to date suggest that immunotherapeutic approaches for the treatment of CLL might finally be fulfilling their promise. Introduction consideration of HSCT and when in their disease course HSCT Over the past decade, there have been significant advances in our should be offered. Combination immunochemotherapy with rituximab, fludarabine, exploit GVL in CLL while avoiding the significant morbidity and and cyclophosphamide is currently established as the frontline mortality associated with myeloablative conditioning. RIC regi- therapy of choice, with overall response rates of 95% and complete mens allow transplantation in older patients, making this approach remission (CR) rates of 44%. High-risk patients include those requiring treatment who Role of hematopoietic stem cell transplantation in CLL have p53 abnormalities (who merit allogeneic SCT in first response), Currently, allogeneic hematopoietic stem cell transplantation (HSCT) patients who fail to achieve CR or who progress within 12 months after remains the only curative option for CLL. The key to its activity is purine analogs, those who relapse within 24 months after having the GVL effect in which the transplanted hematopoietic stem cells achieved a response with purine-analog-based combination therapy, differentiate into effector cells capable of mounting an antitumor those who have relapsed after prior autologous SCT, or those patients immune response, which is likely directed at minor host antigenic who are fludarabine refractory. This effect is known to be primarily T-cell mediated, exception of cytogenetics for detection of p53 deletions, none of these although it remains unclear whether it is due to improved T-cell categories requires assessment of biologic risk factors. Ongoing function, the presence of allogeneic MHC molecules, or a combina- prospective clinical studies will determine the impact of biomarkers tion of both. HSCT is not a suitable treatment option for the majority of the identification of patients at sufficiently high risk to merit the use of patients with CLL. The disease usually follows an indolent course; allogeneic SCT in first CR. Allogeneic SCT has the potential to induce many patients never require any therapy and most patients are too long-term remission in patients with deletion 17p,13 and the mutational elderly to undergo this procedure.
