    Abstract:
    OBJECTIVE: To investigate the clinical features, treatment modalities and the prognosis of advanced neuroblastoma in children. METHODS: The medical records of 63 children with stage III or IV neuroblastoma from January 1996 to December 2005 were retrospectively reviewed. Sixty patients were treated by tumor resection and (or) chemotherapy and (or) radiation. Fourteen out of the 60 patients received another autologous peripheral blood stem cell transplantation. RESULTS: Of the 63 patients with advanced neuroblastoma, the male/female ratio was 2.7:1 and the median age at diagnosis was 4 years old. Most of the initial symptoms included pyrexia, abdominal pain, abdominal mass, and leg or articular pain. Primary tumor sites were adrenal (38%), retroperitoneal (35%), mediastinal (17%), pelvic (6%) and cervical (2%). The sites of metastasis at diagnosis included local (41%) and (or) distant (37%) lymph nodes, bone marrow (60%), bone (46%) and liver (16%). The median survival time of the 63 patients was 32.7 months. The 2-year survival rate was 44.3%. Statistical analysis demonstrated that unfavorable survival prognostic factors were the following: age > 1 year at diagnosis (P < 0.05); serum neuro-specific enolase > 100 mg/L (P < 0.05); serum lactic dehydrogenase > 1500 U/L (P < 0.01); serum ferritin >150 mg/L (P < 0.05). The overall survival period of the patients was prolonged through total resection of the primary tumor (P < 0.05). Intensive chemotherapy in combination with autologous peripheral blood stem cell transplantation could also result in a prolonged overall survival period (P < 0.01). CONCLUSIONS: Neuroblastoma with advanced stages often presents with various clinical manifestations and has a poor prognosis. It is beneficial to improve the prognosis of neuroblastoma through an early diagnosis and a comprehensive therapy including total resection of the primary tumor, autologous peripheral blood stem cell transplantation and intensive chemotherapy.
