Factors influencing survival in children with recurrent neuroblastoma

J Pediatr Hematol Oncol. 2004 Apr;26(4):227-32. doi: 10.1097/00043426-200404000-00003.

Abstract

Despite advances in multimodal therapy for neuroblastoma, survival from advanced disease remains poor. Children are now offered a wide variety of salvage regimens following relapse. A retrospective review was performed on 31 patients with recurrent neuroblastoma treated at one institution between 1995 and 2001. At initial diagnosis, 27 patients had metastatic disease and 11 had N-myc amplification (NMA). The median time to recurrence from diagnosis was 16.1 months. Seventeen patients received salvage therapy, with a median of three salvage regimens per patient. The median survival time from relapse was 8.4 months. The median survival time was significantly shorter for recurrence less than 6 months after stem cell transplantation (2.9 vs. 13.3 months; P = 0.003) and for patients with NMA (2.7 vs. 15.1 months; P < 0.0001). Overall, salvage therapy led to a significantly longer median survival time (22.4 vs. 3.3 months; P = 0.0003); however, salvage therapy extended the median survival time only from 2.2 to 3.2 months for patients with NMA and from 0.7 to 5.8 months for patients with early relapse after stem cell transplantation. Multiple salvage regimens prolong survival significantly, especially for patients with no NMA and for relapses more than 6 months after stem cell transplantation, but the long-term disease-free survival after recurrent disease remains dismal.
