Background: The European multicenter study LNESG1 was designed to evaluate the safety and efficacy of surgical treatment alone in patients with localised neuroblastoma. In a retrospective, observational study we examined the impact of image-defined risk factors (IDRF) on operative complications and survival (EFS and OS).
Procedure: 534 patients with localised, non-MYCN amplified neuroblastoma were recruited between 1995 and 1999.
Background: International Neuroblastoma Staging System (INSS) Stage 3 neuroblastoma is a heterogeneous disease. Data from the International Neuroblastoma Risk Group (INRG) database were analyzed to define patient and tumor characteristics predictive of outcome.
Procedure: Of 8,800 patients in the INRG database, 1,483 with INSS Stage 3 neuroblastoma and complete follow-up data were analyzed.
