Treatment strategies involving dose intensification have recently demonstrated improvements in cure compared with older trials. However, dose-intensive therapy is associated with increased acute and long-term toxicities, particularly in pediatric patients. The Children's Cancer Group initiated this pilot study to assess the feasibility and toxicity of a moderate dose-intensive regimen, BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine and prednisone), in children and adolescents with advanced-stage Hodgkin's lymphoma (HL). ⋯ BEACOPP chemotherapy is feasible and generally well tolerated in children with advanced-stage HL. The absence of reported progressive disease and only one relapse to date is encouraging.

Comparative Study Clinical Trial
Allogeneic hematopoetic stem-cell transplantation for patients with relapsed or refractory lymphomas: comparison of high-dose conventional conditioning versus fludarabine-based reduced-intensity regimens.
Allogeneic hematopoetic stem-cell transplantation (alloHSCT) has curative potential for poor risk lymphoma patients due to the graft-versus-lymphoma effect. High non-relapse mortality with conventional high-dose conditioning indicates the necessity for less toxic transplant strategies. ⋯ AlloHSCT induces high rates of complete remission in advanced lymphoma patients, even when the tumor had relapsed after autologous HSCT. It should be considered earlier as part of the therapeutic options in poor risk patients to avoid non-relapse mortality associated with extensive pretreatment. Our novel reduced conditioning regimens show promising results, especially in heavily pretreated patients, and improve survival after allogeneic transplantation.

Randomized Controlled Trial Comparative Study Clinical Trial
Current clinical trials for the treatment of advanced-stage Hodgkin's disease: BEACOPP.
The bleomycin-etoposide-doxorubicin-cyclophosphamide-vincristine-procarbazine-prednisone (BEACOPP) regimen was developed to investigate the potential of moderate dose escalation of conventional polychemotherapy to improve the unsatisfactory treatment results in advanced-stage Hodgkin's lymphoma (HL). Following pilot studies, the randomised trial HD 9 demonstrated that BEACOPP (baseline dose) attained superior failure-free survival to COPP/ABVD, and that dose escalation made a further marked improvement. Toxicity was severe but manageable. ⋯ The BEACOPP regimen is highly effective, and moderate dose escalation makes a further worthwhile improvement in tumour control. Current trials will measure BEACOPP against the international standard and show whether the amount of chemotherapy and/or radiotherapy can be reduced.
