A randomized as st currently in the trash Eastern Cooperative Oncology Group BEST CONFIRMS’s Full challenge to demonstrate a positive nitive tipifarNib. As maintenance therapy after remission of all subgroups of AML patients with poor risk features, especially those with secondary Rer AML or adverse cytogenetics and RER A future Danusertib goal is to determine who tipifarnib benefit from the addition in the MRD. This can be particularly difficult in patients with normal cytogenetics, where clinical outcomes and cure rates can vary widely, reflecting the heterogeneity t T ECTS at the molecular level. K in this regard Recent studies may challenge or monogenic mutations and gene expression signatures to distinguish prognostic subgroups k normal cytogenetics AML. In sum, the results of this descr phase II study about.Limited which some patients with low risk containment t AML Lich, the Rer secondary Re AML and cytogenetics negative or positive tipifarnib maintenance therapy, no clinically or biologically significant risk important.
Future studies should examine this approach and other randomized processing tipifarnib dose cycles, and a placebo controlled Lee, Lee tipifarnib maintenance therapy. After all, not on molecular EPO906 stratification of the cation properties refinancing capacity Th F, based in the subgroup of patients, Rhymes SATM t advantages goals tipifarnib maintenance balanced approach. Resistance to tipifarnib malignant cells have an amazing F Ability, F.. Doing a new anti-tumor agent, and it is likely that the RTI is no exception to this resistance, be either intrinsic or acquired drug effi ciency frontier net Today FTI resistance in various cell lines, which were targeted setting or have developed genetically express enzymes detected mutations FT.
For example, to define a human cancer cell line resistant c Tipifarnib Lon, continuous drug exposure produced a significant reduction of the enzyme itself without enzymes FT mutations or aberrations in the activation of enzymatic subunits. PH construction Hnlichen lonafarnibresistant ? ?A LL cell line transgenic Mice were prepared by culturing these cells in the stroma in the presence of increasing concentrations lonafarnib. The resulting cells are resistant Erh Lonafarnib significant increase in gene expression of the new ATP-binding cassette transporter homologous ATPA and fa are compatibility t interesting widerstandsf relatively erh Obtained by and imatinib.
