Children and adolescents with high-stage (stage III or IV) anaplastic large cell lymphoma (ALCL) have a disease-free survival of approximately 60% to 75%.[1,2,3,4,5] It is unclear which strategy is best for the treatment of high-stage ALCL. The German Berlin-Frankfurt-Munster (BFM) group used six cycles of intensive pulsed therapy, similar to their B-cell non-Hodgkin lymphoma (NHL) therapy (GER-GPOH-NHL-BFM-90 [NHL-BFM-90]).; [Level of evidence: 1iiA] Building on these results, the European Intergroup for Childhood NHL (EICNHL) group conducted the FRE-IGR-ALCL99 study (based on the GER-GPOH-NHL-BFM-90 regimen). First, this randomized study demonstrated that methotrexate 1 g/m2 infused over 24 hours plus intrathecal methotrexate and methotrexate 3 g/m2 infused over 3 hours without intrathecal methotrexate yielded similar outcomes.[Level of evidence: 1iiC] However, methotrexate 3 g/m2 over 3 hours had less toxicity than methotrexate 1 g/m2 over 24 hours.; [Level of evidence: 1iiDi] Secondly, FRE-IGR-ALCL99 randomly assigned patients to limited vinblastine versus prolonged (1 year) vinblastine exposure. Patients receiving the vinblastine plus chemotherapy regimen had a better event-free survival (EFS) in the first year after therapy (91%) than those not receiving vinblastine (74%); however, after 2 years of follow-up, the EFS was 73% for both groups.[Level of evidence: 1iiDi] Of note, the Pediatric Oncology Group (POG) trial (POG-9317) demonstrated no benefit of adding methotrexate and high-dose cytarabine to 52 weeks of the APO (doxorubicin, prednisone, and vincristine) regimen. The Italian Association of Pediatric Hematology/Oncology group has used a leukemia-like regimen for 24 months in LNH-92, with similar results as other regimens. The CCG-5941 study tested an approach similar to LNH-92, with more intensive induction and consolidation with maintenance for 1 year total duration of therapy, with similar outcome, but significant hematologic toxicity was observed.[Level of evidence: 2A]

Current Clinical Trials
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with stage III childhood anaplastic large cell lymphoma and stage IV childhood anaplastic large cell lymphoma. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
General information about clinical trials is also available from the NCI Web site.
