ABSTRACT
<p><b>OBJECTIVE</b>To study the clinical features and treatment outcome of children with mature B-cell non-Hodgkin's lymphoma (B-NHL).</p><p><b>METHODS</b>A total of 28 previously untreated children with mature B-NHL were enrolled and given the chemotherapy regimen of CCCG-B-NHL-2010. Among them, 20 were given rituximab in addition to chemotherapy. The children were followed up for 31 months (ranged 4-70 months). A retrospective analysis was performed for the clinical features of these children. The Kaplan-Meier method was used for survival analysis. A univariate analysis was performed to investigate the prognostic factors.</p><p><b>RESULTS</b>Among the 28 children, 17 (61%) had Burkitt lymphoma, 8 (29%) had diffuse large B-cell lymphoma (DLBCL), and 3 (11%) had unclassifiable B-cell lymphoma. As for the initial symptom, 13 (46%) had cervical mass, 10 (36%) had maxillofacial mass, 9 (32%) had hepatosplenomegaly, 5 (18%) had abdominal mass, and 5 (18%) had exophthalmos. Of all children, 14 had a lactate dehydrogenase (LDH) level of <500 IU/L, 3 had a level of 500-1 000 IU/L, and 11 had a level of ≥ 1 000 IU/L. After two courses of chemotherapy, 21 children achieved complete remission and 7 achieved partial remission. At the end of follow-up, 24 achieved continuous complete remission and 4 experienced recurrence. The 2-year event-free survival rate was (85.7± 6.6)%. The children with bone marrow infiltration suggested by bone marrow biopsy, serum LDH ≥500 IU/L, and bone marrow tumor cells >25% had a low 2-year cumulative survival rate.</p><p><b>CONCLUSIONS</b>The CCCG-B-NHL 2010 chemotherapy regimen combined with rituximab has a satisfactory effect in the treatment of children with B-NHL. Bone marrow infiltration on bone marrow biopsy is associated with poor prognosis.</p>
