title: Treatment outcome of Chinese children with anaplastic large cell lymphoma by using a modified B-NHL-BFM-90 protocol.
abstract: Pediatric anaplastic large cell lymphoma (ALCL) has rarely been reported in Chinese pediatric patients. This study evaluated the clinical characteristics and treatment outcome of Chinese pediatric patients with ALCL. Between October 2002 and October 2012, 39 untreated pediatric patients with ALCL were enrolled at a single institution. The patients were stratified into three groups (R1, R2, and R3) based on the stage of the disease, clinical risk factors, and chemotherapeutic response, and received different intensive chemotherapy regimens based on a modified B-NHL-BFM-90 protocol. Of the 39 patients, 22 were boys, and 17 were girls, with a median age at diagnosis of 10 years (range 2-16 years), 91.2% were anaplastic lymphoma kinase (ALK)-positive. The patient groups R1, R2, and R3 accounted for 12.8%, 30.4%, and 56.4% of the total, respectively. 87.2% of patients were stage III/IV. At a median follow-up period of 52 months (range 15-136 months), seven patients relapsed and three patients died of their disease. The 5-year event-free survival for all patients was 81.4% ± 6.4%, with 100%, 83.3% ± 10% and 75.3% ± 9.8% for groups R1, R2, and R3, respectively. The overall survival for all patients was 92.2% ± 4.3%. Our study demonstrates that a risk-stratified treatment with a modified B-NHL-BFM-90 protocol is efficacious for Chinese children with ALCL.
