title: Curability of relapsed childhood B-cell non-Hodgkin's lymphoma after intensive first line therapy: a report from the Société Française d'Oncologie Pédiatrique.
abstract: The very high cure rate in advanced B-cell non-Hodgkin's lymphoma in children using intensive multiagent therapy has been previously reported by the French Sociéte Française d'Oncologie Pédiatrique lymphoma Malin B type (LMB) group. To address the issue of salvageability in an unselected group of patients who had all received the same front-line therapy, the outcome of relapses following the LMB 84 (216 patients) protocol have been reviewed. Fourteen percent of patients achieving complete remission (CR) relapsed, ie, 27 of 195. Relapse sites comprised the central nervous system (CNS) alone (6 cases), lung or mediastinum (2 cases), abdomen (8 cases), head and neck (2 cases), or multifocal (9 cases). There were three early deaths due to disease. Twenty-four patients received rescue chemotherapy regimens and 15 were treated with high-dose chemotherapy and bone marrow rescue (1 allogeneic). Of these, 9 were in second CR, 4 in second partial remission, and 2 treated during progressive disease. One died in CR from treatment-related toxicity. Ten relapsed postbone marrow transplant and 4 are alive disease free and probably cured. Two of the long-term survivors had some delay during initial chemotherapy due to toxicity and two were isolated CNS relapses. Twelve of 27 patients did not proceed to megatherapy (12 of 12 died).
