BACKGROUND Elderly patients (age > or = 65 years) with acute myeloid leukemia (AML) generally have a poor prognosis. AML-type therapy results are often derived from studies in younger patients and may not apply to elderly AML. Many investigators and oncologists advocate, at times, only supportive care or frontline single agents, Phase I-II studies,(More)
Patients ≥ 70 years of age with acute myeloid leukemia (AML) have a poor prognosis. Recent studies suggested that intensive AML-type therapy is tolerated and may benefit most. We analyzed 446 patients ≥ 70 years of age with AML (≥ 20% blasts) treated with cytarabine-based intensive chemotherapy between 1990 and 2008 to identify risk groups for high(More)
Epigenetic therapy with hypomethylating drugs is now the standard of care in myelodysplastic syndrome (MDS). Response rates remain low, and mechanism-based dose optimization has not been reported. We investigated the clinical and pharmacodynamic results of different dose schedules of decitabine. Adults with advanced MDS or chronic myelomonocytic leukemia(More)
BACKGROUND Modern intensive chemotherapy regimens have improved the prognosis for patients with adult acute lymphocytic leukemia (ALL). With these regimens, the complete response rates are now reported to be > 80%, and the long-term survival rates range from 30% to 45%. The current analysis updated the long-term results with the original hyperfractionated(More)
Dasatinib and nilotinib are potent tyrosine kinase inhibitors (TKIs) with activity against many imatinib-resistant chronic myeloid leukemia (CML) clones with BCR-ABL kinase domain (KD) mutations, except T315I. We assessed for changes in the BCR-ABL KD mutation status in 112 patients with persistent CML who received a second-generation TKI after imatinib(More)
BACKGROUND The prognosis of patients with chronic myelogenous leukemia (CML) after failure of imatinib mesylate therapy is not well documented. METHODS The outcome of 420 patients with CML post-imatinib failure (resistance-recurrence in 374; toxicities in 46) were reviewed in relation to survival, overall, and by different therapies. RESULTS The(More)
BACKGROUND Adult Burkitt-type lymphoma (BL) and acute lymphoblastic leukemia (B-ALL) are rare entities composing 1% to 5% of non-Hodgkin lymphomas NHL) or ALL. Prognosis of BL and B-ALL has been poor with conventional NHL or ALL regimens, but has improved with dose-intensive regimens. METHODS To evaluate the addition of rituximab, a CD20 monoclonal(More)
PURPOSE The current classification systems of myelodysplastic syndromes (MDS), including the International Prognostic Scoring System (IPSS), do not fully reflect the molecular heterogeneity of the disease. Molecular characterization may predict clinical outcome and help stratify patients for targeted therapies. Epigenetic therapy using decitabine, a DNA(More)
BACKGROUND Therapy for patients with myelodysplastic syndrome (MDS) with hypomethylating agents, like decitabine and 5-azacitidine, has produced favorable results. In this study, the authors update their experience with decitabine in patients with MDS and analyze the cytogenetic response patterns and prognostic factors associated with decitabine therapy. (More)
PURPOSE Imatinib mesylate, a specific Bcr-Abl tyrosine kinase inhibitor, has shown encouraging activity in chronic myelogenous leukemia (CML). EXPERIMENTAL DESIGN We treated 237 patients (median age, 50 years; age range, 18-82 years) with Philadelphia chromosome (Ph)-positive accelerated-phase CML with oral imatinib mesylate at daily doses of 400 mg (26(More)
