Clinical features and prognosis of children with acute lymphoblastic leukemia and different platelet levels

To study the association of platelet level at diagnosis with prognosis in children with acute lymphoblastic leukemia (ALL). A total of 892 children with ALL who underwent chemotherapy with the CCLG-ALL 2008 regimen were enrolled. According to the platelet count at diagnosis, these children were divi...

The thrombocytopenia group was further divided into (50- <100)×10 /L (n=243), (20- <50)×10 /L (n=263), and <20×10 /L (n=123) subgroups. The association of clinical features (sex, age, immunophenotype, and molecular biology) with event-free survival (EFS) and overall survival (OS) was analyzed. Compared with the thrombocytopenia group, the normal platelet count group had significantly lower positive rate of MLL gene rearrangement and recurrence rate (P<0.05), as well as a significantly higher 10-year EFS rate (P<0.05).
