Since leukemic cells primed by exposure to fludarabine exhibit enhanced accumulation of cytarabine triphosphate (the cytotoxic nucleotide of cytarabine), especially with continuous cytarabine (AraC) infusion, a phase II trial was designed to explore the feasibility and efficacy of a combination chemotherapy associating fludarabine, mitoxantrone (MXN), and high-dose cytarabine (continuous infusi...
Acute myeloid leukemia (AML) is a clonal disease originating from myeloid progenitor cells with a heterogeneous genetic background. High-dose cytarabine is used as the standard consolidation chemotherapy. Oncogenic RAS mutations are frequently observed in AML, and are associated with beneficial response to cytarabine. Why AML-patients with oncogenic RAS benefit most from high-dose cytarabine po...
The authors report an acute cerebral and cerebellar syndrome in a patient treated with high-dose cytarabine. Diffuse high-intensity lesions in the central white matter on T2-weighted MR completely reversed with resolution of the clinical syndrome. Although the autopsy revealed cerebellar injury, the cerebral cortex was grossly and microscopically normal, consistent with a reversible process.
Early intensification of chemotherapy with high-dose cytarabine either in the postremission or remission induction phase has recently been shown to improve long-term relapse-free survival (RFS) in patients with acute myeloid leukemia (AML). Comparable results have been produced with the double induction strategy. The present trial evaluated the contribution of high-dose versus standard-dose cyt...
Introduction. The incidence of Acute Myeloid Leukemia (AML) increases progressively with age and its treatment is challenging. This prospective case control study was undertaken to compare the safety, efficacy, and cost-effectiveness of decitabine with those of cytarabine in older patients with newly diagnosed AML who are not fit for intensive chemotherapy. Materials and Methods. 30 eligible pa...
The prognosis for patients with primary central nervous system (CNS) lymphoma (PCNSL) who relapse after the initial response is usually poor. A standard treatment for relapsed PCNSL has not yet been identified because of the heterogeneity of the therapies employed and the lack of large, prospective clinical trials. We describe a 46-year-old relapsed PCNSL patient who was successfully treated wi...
PURPOSE Incorporation of cytarabine into DNA activates checkpoint kinase 1 (Chk1), which stabilizes stalled replication forks, induces S-phase slowing, and diminishes cytarabine cytotoxicity. The selective Chk1 inhibitor SCH 900776 abrogates cytarabine-induced S-phase arrest and enhances cytarabine cytotoxicity in acute leukemia cell lines and leukemic blasts in vitro. To extend these findings ...
OBJECTIVE To evaluate the short-term therapeutic effects of low-dose cytarabine plus surgical resection on elderly patients with trigeminal nerve tumor and to observe the safety. METHODS A total of 120 elderly patients with trigeminal nerve tumor were divided into a treatment group and a control group by random draw (n=60), and both groups were subjected to resection by stereotactic image-gui...
The value of administering sequential courses of chemotherapy containing high-dose cytarabine in both induction and consolidation therapy for acute myeloid leukemia (AML) has not been assessed in a prospective randomized trial. Two hundred ninety-two AML patients aged 15 to 60 years were enrolled in the Australasian Leukaemia and Lymphoma Group (ALLG) AML trial number 7 (M7) protocol to evaluat...
