ABSTRACT
OBJECTIVE:
To evaluate the prognosis value of average daily platelet amount increase in children with B-cell acute lymphoblastic leukemia(B-ALL) treated by CCCG-ALL-2015 regimen.METHODS:
106 children with primary B-ALL were retrospective analyzed, standardized MRD test protocol was used to detect the MRD level (19 d and 46 d) after chemotherapy. The platelet count was measured by Sysmex XE-2100. Kaplan-Meier survival curve statistics was used to analyze the event free survival(EFS) rate of the children.RESULTS:
The trend of negative correlation existed between PPC and TPR (rs=-0.519, P=0.021). The 3-year EFS rate of the patients in Ap>5.4×109/L group was 95.7%, which was significantly higher than those in Ap≤5.4×109/L group(79.5%) (χ2=5.236, P=0.035); multivariate analysis showed that Ap≤5.4×109/L was the independent prognostic factor affecting survival of the patients (RR=3.978; 95%CI 1.336-11.523, P=0.041). With both MRD and Ap≤5.4×109/L as candidate variables, Ap≤5.4×109/L lost its independent prognostic value (RR=1.225; 95%CI 0.892-13.696, P=0.089), the correlation between d 19/d 46 MRD levels and Ap>5.4×109/L (χ2=4.318, P=0.038) could explain the phenomenon.CONCLUSION:
Ap can reflect the effect of B-ALL chemotherapy and can be used to monitor the curative effect and prognosis of B-ALL children.Palavras-chave
