Abstract:
Objective To analysis the clinical characteristics and the long-term effect of children with acute lymphoblastic leukemia (ALL).Methods From 2005 to 2010,80 newly diagnosed ALL children were enrolled and treated with protocol based on ALL-BFM2002.The five-years overall survival (OS)and event-free survival(EFS) were analyzed by the method of Kaplan-Meier.Results For the 80 patients,male to female ratio is 1.22∶1.The median age was 4.3 years.33 were in standard risk(41.2%),37 were in medium risk(46.3%),and 10 were in high risk(12.5%).22 had white blood cell count ≥20 x 109/L(27.5%).three patients with BCR-ABL translocation(3.8%),one patient with MLL gene rearrangement(1.3%),17 patients with TEL-AML translocation (21.3%).During induction therapy,79 patients (98.8 %) achieved complete remission(CR).The five-years OS and EFS were (85.9 ± 4.0) % and (79.2 ± 4.7) % respectively.The five-years EFS:SR group (86.6 ± 6.4) %,IR group (81.1 ± 6.4) %,HR group (48.0 ± 16.4) %.The difference among risk groups was statistically significant(x2 =7.03,P <0.05).12 patients relapsed(15.0%),the median time from diagnosis to relapse was 23.5 months.11 patients died (13.8 %).Conclusion According to stratification by risk factors and risk-adapted therapy,the quality of ALL children's life had improved.
