Background: The New York protocol, primarily developed to treat children with high-risk acute lymphoblastic leukemia (ALL), is characterized by early intensive chemotherapy followed by less intensive pulse chemotherapy during maintenance. This study was performed to evaluate the efficacy of this protocol in children with non-Hodgkin lymphoma (NHL), irrespective of histopathologic subtype. Procedure: From January 1996 to December 2011, 146 newly diagnosed children and adolescents with NHL were treated with the modified New York protocol. Treatment duration was determined according to the stage. Results: The 5-year failure-free survival (FFS), event-free survival (EFS), and overall survival (OS) rates were 86.7±2.9%, 79.1±3.5%, and 84.7±3.1%, respectively. The 5-year FFS for patients with mature B-cell lymphoma, T-cell and NK-cell lymphoma (T/NK-cell lymphoma), and lymphoblastic lymphoma were 95.4±2.6%, 76.1±7.0%, and 82.1±6.6%, respectively. In multivariate analysis, T/NK-cell lymphoma and non-complete response (non-CR) at the end of induction chemotherapy were associated with a significant increase in treatment failure rate (relative risk [RR], 4.5, P=0.03, and RR, 5.0, P=0.002). Conclusion: The protocol appears to be efficacious in the treatment of children and adolescents with NHL, irrespective of histopathologic subtype. Achievement of CR after intensive induction chemotherapy was an important prognostic factor. Early response to treatment may be used to stratify risk groups and modify therapy in children with NHL.
