A molecularly HLA- patients with an available matched sibling donor up to the age of 40 matched unrelated donor (UD) is in this situation the best alternative to 50 years. A curve illustrating the respective outcome for patients receiving transplantations either from a sibling donor or from an Transplantation in patients younger than 40 years unrelated one is shown in Figure 1. The use of other alternative Conditioning regimen with CY ATG. Being a non-neoplastic source of stem cells, including cord blood and a haploidentical hematologic disorder, the main goal of transplantation in aplastic familial donor, have been reviewed recently3 and will be discussed anemia is to achieve successful engraftment with no acute or by Kulasekararaj and Marsh elsewhere in this publication4 (these chronic GVHD.

Therefore, adequate Transplantation from HLA-identical sibling donors lymphoablative and immuno-ablative components of the prepara- Allogeneic hematopoietic SCT (HSCT) is the most likely curative tive regimen are important. The addition of ATG to CY given at a treatment option for SAA and should be the upfront therapeutic total dose of 200 mg/kg has been demonstrated to promote both option of choice for young patients. The outcome of allogeneic excellent engraftment and long-term outcome. In a nonrandomized HSCT (and of immunosuppressive therapy) has improved remark- trial, this combination resulted in a lower incidence of GVHD and ably during the last decade because of improvements in all aspects improved survival compared with historical controls who received of transplantation, including supportive care. It is noteworthy that one prospective random- matched sibling transplantation to an older patient who is at higher ized trial involving 134 patients did not show a significant benefit risk of GVHD and therefore higher morbidity and mortality rate from the addition of ATG,7 which nevertheless improved the must be weighed carefully against the benefits of IST, which may long-term survival rate by 10% (thus raising the power of the trial to produce a sustained remission but is associated with late clonal detect a statistical significance). Prevention of graft failure can be abnormalities such as myelodysplastic syndrome and acute myeloid accomplished by the use of other more intense conventional leukemia. In a CIBMTR analysis, the age at transplantation beyond conditioning, including radiation-based regimens. However, this which outcomes differ were analyzed and risk factors that may be must be strongly discouraged due to higher transplantation-related modified to improve survival after HLA-matched sibling donor long-term morbidity and mortality. Use of other conditioning transplantation for SAA including older patients were identified. Patients older than 40 years were more likely to have had IST, poor performance scores, and a longer interval from diagnosis to Use of BM as the source of stem cell. Neutrophil recovery was similar in all age groups, must be used as the stem cell source for all patients with aplastic but patients older than 40 years had a lower likelihood of platelet anemia, because the use of peripheral blood stem cells (PBSCs) is recovery compared with patients younger than 20 years but not associated with increased risk of chronic GVHD. Despite earlier compared with those 20 to 40 years of age. Compared with patients engraftment with the use of PBSCs, a joint European Group for younger than 20 years, mortality risks were higher in patients older Blood and Marrow Transplantation (EBMT)/Center for Interna- than 40 years and those 20 to 40 years of age. Risks were also higher tional Blood and Marrow Transplant Research (CIBMTR) retrospec- in patients with poor performance scores and when the interval from tive analysis suggests inferior outcome with the use of PBSCs in this diagnosis to transplantation was longer than 3 months, suggesting disease, particularly in young patients. Adequate BM stem cell dose CY ATG have also been considered. For patients between the is expected to be associated with improved outcome.

A small-molecule inhibitor of Anderson Cancer Center clinical experience. Margarete Fischer-Bosch Institute of Clinical Pharmacology, Stuttgart, Germany MYC, a member of the helix-loop-helix leucine zipper family of nuclear transcription factors, is a potent proto-oncogene primarily identified as the target of the t(8;14)(q24;q32) chromosome translocation in Burkitt lymphoma. Activation of the MYC gene in normal cells both results in enhanced cellular proliferation and up-regulation of pro-apoptotic pathways, reflecting the tight regulation of the molecule in the normal cellular system. In the process of transformation, these secondary inhibitory functions of the MYC molecule have to be overcome through secondary mutations of the MYC gene itself and/or by abrogating the inhibitory effects of physiological regulators and/or repressors of proliferation such as BCL2, BCL6, BLIMP1, or others. Most aggressive lymphomas, therefore, harbor additional oncogenic alterations that cooperate with MYC deregulation, with different alterations identified in human solid or hematological tumors. These alterations are likely to counteract the pro-apoptotic function of MYC. MYC gene alterations in diffuse large B-cell lymphomas and in B-cell lymphomas, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma are frequently associated with BCL2 or/and BCL6 translocations conferring a very aggressive behavior. This review summarizes inherent factors of the biology and function of MYC important in the process of transformation, especially taking account the interdependence of MYC on various cellular networks that have to be co-deregulated to achieve the full malignant phenotype. In addition, microRNAs pathways (miRs) have been found to assist in controlling its expression. MYC itself is activated by binding the histone acetyltransferases CBP/ p300 and TIP60/GCN5 or the transcription factor P-TEFb, among Introduction others. Transcriptional repression of MYC is mediated by interaction The expression of the proto-oncogene MYC is deregulated in a large with the transcription factor MIZ-1, which prevents recruitment of variety of cancers and, in these tumors, overexpression of MYC is the activating molecule p300 and enables binding of the gene- often associated with a poor prognosis. The MYC gene is located in silencing DNA-methyltransferase DNMT3a. Other transcription band 8q24 in the subterminal portion of the long arm of chromo- factors such as MAD titrate out MYC from the complexes, followed some 8.
