BEACOPP chemotherapy is a highly effective regimen in children and adolescents with high-risk Hodgkin lymphoma: a report from the Children's Oncology Group.
Dose-intensified treatment strategies for Hodgkin lymphoma (HL) have demonstrated improvements in cure but may increase risk for acute and long-term toxicities, particularly in children. The Children's Oncology Group assessed the feasibility of a dose-intensive regimen, BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisone) in children with high-risk HL (stage IIB or IIIB with bulk disease, stage IV). Rapidity of response was assessed after 4 cycles of BEACOPP. Rapid responders received consolidation therapy with guidelines to reduce the risk of sex-specific long-term toxicities of therapy. Females received 4 cycles of COPP/ABV (cyclophosphamide, vincristine, procarbazine, prednisone, doxorubicin, bleomycin, vinblastine) without involved field radiation therapy (IFRT). Males received 2 cycles of ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) with IFRT. Slow responders received 4 cycles of BEACOPP and IFRT. Ninety-nine patients were enrolled. Myelosuppression was frequent. Rapid response was achieved by 74% of patients. Five-year event-free-survival is 94%, IFRT with median follow-up of 6.3 years. There were no disease progressions on study therapy. Secondary leukemias occurred in 2 patients. Overall survival is 97%. Early intensification followed by less intense response-based therapy for rapidly responding patients is an effective strategy for achieving high event-free survival in children with high-risk HL.
