OBJECTIVE: To analyze the relationship between the early treatment response and the pregnosis in children with acute lymphoblastic leukemia(ALL). METHODS: Two hundred and Seventy-eight ALL children diagnosed and treated in Hainan general hospital from March 2013 to March 2017 were collected. All ALL children received therapy with CCLg-ALL-2008 regimen. The 3 year event-free survival (EFS) rate of ALL children in different groups was analyzed in terms of 4 indexes including sensitivity response to prednison at day 8 (D8-SRP), bone marrow remission at day 15 (D15-BMR) and at day 33 (D33-BMR), and minimal residual disease at day 33 (D33-BMR), and minimal residual disease at day 33(D33-MRD). These 4 indexes and other indexes possibly affecting the prognosis of ALL children were enrolled in Cox regression model for analysis of independent factors affecting the prognosis of ALL children. RESULTS: The D8-SRP test showed that among 269 ALL children, 240(89.22%) cases displayed prednisone poor response (PPR); the 3-year EFS rate in predrisone good response(PGR) group was significantly higher than that in PPR group(P<0.05). The D15-BMR detection showed that among 262 ALL children, the bone marrow remission(BMR) as M1 was observed in 230 cases (87.79%), M2 in 20 cases (7.63%) and M3 in 9 cases (4.58%); the 3-year EFS rate showed as follows:M1 group >M2 group >M3 group(P<0.05). The D33-BMR detection showed that among 257 ALL children, the BMR as M1 was observed in 227 cases (88.33%), M2 in 21 cses(8.17%) and M3 in 9 caes (3.51%); the 3-year EFS rate in 3 groups showed as follows: M1 group >M2 group >M3 group(P<0.05). The D33-MRD detection showed that among 185 ALL children, MRD<10-10 was found in 128 cases (69.19%), MRD≥10-4-10-2 in 43 cases (23.24%), MRD ≥10-2 in 14 cases (7.57%); the 3-year EFS rate in 3 groups showed as follows: MRD <10-4 group > MRD≥ 10-4-10-2 group>MRD≥10-2 group. The Cox regression analysis showed that PPR in D8-SRP test, M2 and M3 in D15 and D33 BMR detection, and MRD≥10-2 in D33 MRD detection as well as T-ALL typing were independent risk factors affecting the prognosis of ALL children. CONCLUSION: The early treatment response can predict the prognosis of ALL children, which is an independent prognostic factor for ALL children.
