Despite intensification of treatment with high-dose chemotherapy (HDC) and autologous bone marrow transplantation (AMBT), the prognosis of poorly responding metastatic neuroblastoma remains bad. Recombinant IL-2 (rIL-2) was used after ABMT to enhance the immune response against the tumor and thereby to improve survival of these patients. In this study, five courses of rIL-2 were administered as a continuous intravenous infusion every 2 weeks, the first course lasting 5 days, and the other four 2 days. rIL-2 treatment was to begin within 120 days of BMT. This study demonstrates the feasibility of rIL-2 soon after HDC and ABMT. The maximum tolerated dose (MTD) was 12 x 10(6) U/m2/day. Clinical toxicity was similar to that observed in adults, moderately increased by the proximity of ABMT; in a previous study we demonstrated that the MTD in non-grafted children was 18 x 10(6) U/M2/day. Nevertheless, half of the patients were not able to receive rIL-2 therapy after ABMT, and only 6/12 received 100% of the planned dose, mainly because of thrombocytopenia. If peripheral stem cell transplantation is demonstrated to enhance platelet recovery, more patients could be treated with rIL-2 with the present schedule. Earlier administration of low-dose rIL-2 after BMT associated with ex vivo rIL-2 treatment of the graft could be a more valid way of using rIL-2 to improve survival.

D009447 Neuroblastoma A common neoplasm of early childhood arising from neural crest cells in the sympathetic nervous system, and characterized by diverse clinical behavior, ranging from spontaneous remission to rapid metastatic progression and death. This tumor is the most common intraabdominal malignancy of childhood, but it may also arise from thorax, neck, or rarely occur in the central nervous system. Histologic features include uniform round cells with hyperchromatic nuclei arranged in nests and separated by fibrovascular septa. Neuroblastomas may be associated with the opsoclonus-myoclonus syndrome.
