High-Stage Childhood Anaplastic Large Cell Lymphoma Treatment
Children and adolescents with high-stage (stage III or IV) anaplastic large cell lymphoma have a disease-free survival of approximately 60% to 75%.[1,2,3,4,5,6] It is unclear which strategy is best for the treatment of high-stage anaplastic large cell lymphoma. 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]
Diffuse large B-cell lymphoma is a cancer that starts in white blood cells called lymphocytes. It is also called DLBCL. It usually grows in lymph nodes -- the pea-sized glands in your neck, groin, armpits, and elsewhere that are part of your immune system. It can also show up in other areas of your body.
DLBCL grows fast, but 3 out of 4 people are disease-free after treatment, and about half are cured. And researchers are working to make treatments even better.
There are two types of lymphoma:...
Current data do not suggest superiority for the following standard treatment options.
APO: doxorubicin, prednisone, and vincristine. This regimen can be administered in the outpatient setting. The duration of therapy is 52 weeks and the cumulative dose of doxorubicin in 300 mg/m2.
FRE-IGR-ALCL99: dexamethasone, cyclophosphamide, ifosfamide, etoposide, doxorubicin, IV methotrexate (3 g/m2 arm), cytarabine, prednisolone, and vinblastine. This regimen usually requires hospitalization for administration. The total duration of therapy is 5 months and the cumulative dose of doxorubicin is 150 mg/m2.
