Standard chemotherapy regimens for remission induction of pediatric acute myeloid leukemia (AML) are associated with significant morbidity and mortality. We performed a cohort study to determine the impact of reducing the intensity of remission induction chemotherapy on the outcomes of selected children with AML treated with a low-dose induction regimen plus granulocyte colony stimulating factor (G-CSF) (low-dose chemotherapy (LDC)/G-CSF). Complete response (CR) after two induction courses was attained in 87.0% (40/46) of patients receiving LDC/G-CSF. Post-remission therapy was offered to all patients, and included standard consolidation and/or stem cell transplantation. During the study period, an additional 94 consecutive children with AML treated with standard chemotherapy (SDC) for induction (80/94 (85.1%) of the patients attained CR after induction II, P = 0.953) and post-remission. In this non-randomized study, there were no significant differences in 4-year event-free (67.4 vs. 70.7%; P = 0.99) and overall (70.3 vs. 74.6%, P = 0.69) survival in the LDC/G-CSF and SDC cohorts, respectively. After the first course of induction, recovery of white blood cell (WBC) and platelet counts were significantly faster in patients receiving LDC/G-CSF than in those receiving SDC (11.5 vs. 18.5 d for WBCs (P < 0.001); 15.5 vs. 22.0 d for platelets (P < 0.001)). To examine the quality of molecular response, targeted deep sequencing was performed. Of 137 mutations detected at diagnosis in 20 children who attained hematological CR after two courses of LDC/G-CSF (n = 9) or SDC (n = 11), all of the mutations were below the reference value (variant allelic frequency <2.5%) after two courses, irrespective of the treatment group. In conclusion, children with AML receiving LDC/G-CSF appear to have similar outcomes and mutation clearance levels, but significantly lower toxicity than those receiving SDC. Thus, LDC/G-CSF should be further evaluated as an effective alternative to remission induction in pediatric AML. 相似文献

日本国立大学法人化改革效果分析——以名古屋大学为例 总被引:3,自引:0,他引:3
截至2006年,日本国立大学法人化改革已经进行了两年。根据国立大学法人调查委员会的解释,实施日本国立大学法人制度有三个目的:一是创建富有个性的大学和开展具有国际竞争力的教育研究;二是强化国立大学对国民和社会的责任,并在高校贯彻落实竞争原理;三是实现经营责任明确化,并使大学的经营活动具有灵活性和战略性。简言之,希望通过此次法人化改革,在提高大学自主性和自律性的基础上,提高大学的管理水平,最终提高国立大学教育和研究质量、充分发挥国立大学使命。 相似文献

Citizens of modern societies must trust a broad range of systems and professionals. When distrust arises, professionals are expected to be accountable. This paper draws on conversational material from a preschool team meeting. When a preschool work team prepares to meet a parent who has complained about their recurring neglect to change her child’s nappies ‘in time’, they are found: (1) to carefully review the encounter with the client, (2) in a team-building fashion, to select suitable accounts to offer ‘front stage’ and (3) to internally justify their selection of accounts. Our results indicate that work team members who engaged in backstage rehearsal author the organisation for building trust and, simultaneously ‘rehearse away’ what should remain the organisations’ secrets. Communicating the intent to satisfy was deemed more important than was using evidence from their professional knowledge base. 相似文献
