ABSTRACT
<p><b>OBJECTIVE</b>To analyze the clinical and laboratory data from acute lymphoblastic leukemia (ALL) patients and the results of treatment using 04 Protocol (suggested by the Pediatric Hematology Group of Chinese Medical Association in 2004).</p><p><b>METHODS</b>This study included 88 children with ALL below the age of 18 years during the period from October 1, 2004 to June 30, 2007. Minimal inhibitory concentration (MIC) and clinical risk classification were done and the new chemotherapy regimen was used according to the protocol. Patients were stratified into low-risk (LR), medium-risk (MR), and high-risk (HR) groups. Life table method was used to estimate survival rate and statistical analysis was done by using software SPSS for Windows.</p><p><b>RESULTS</b>From October 2004 to June 2007, 88 childhood ALL patients were treated with the 04 Protocol. Sixty-three (91.30%) patients attained complete remission (CR) and 17 patients lost to follow up. The overall 4-year-event-free survival (EFS) rate (+/- SE) was (59.73 +/- 7.22)%. EFS was (75.60 +/- 9.71)% in the LR (n = 30), (65.50 +/- 11.69)% in the MR (n = 20) and (44.03 +/- 12.36)% in the HR. Relapse occurred in 18.18% of patients. Seven (7.95%) of 88 patients with ALL died during he induction therapy. Infection was the most common cause of death.</p><p><b>CONCLUSION</b>The outcome of patients treated with the 04 Protocol was favorable. Clinical risk classification and the leukemia cells of D19 are independent predictors of prognosis of ALL. High dose methotrexate played an important role in prevention and treatment of central nervous system leukemia. The mortality rate of this chemotherapeutic protocol during induction therapy was high.</p>
