Neuroblastoma: changing incidence and survival in young people aged 0-24 years. A report from the North of England Young Persons' Malignant Disease Registry.

摘要

BACKGROUND AND PROCEDURE: Population based data for neuroblastoma in children and young adults under 25 years at diagnosis were ascertained from the Northern Region Young Persons' Malignant Disease Registry for the period 1968-1995. Age-standardised incidence rates were calculated (ASR) and changes in incidence and survival were investigated. Over the study period 144 patients were registered, of these 136 were children under 15 years at diagnosis (median age: 2.2 years, ASR: 8.6 cases per million children per year), and 8 were 15-24 years (ASR 0.6). RESULTS AND CONCLUSIONS: Incidence of childhood neuroblastoma in the North of England increased significantly over time; ASRs were 5.8 for 1968-1981 and 9.5 for 1982-1995 (rate ratio: 1.6, 95%; CI 1.2-2.3). The increase in incidence was seen in both infants and older children, and in both low stage and advanced disease. Overall 5 year survival was 15% for 1968-1981 and 40% for 1982-1995 (P < 0.0001). Significant improvements in survival were documented across different stage and age-groups, including those over 1 with stage 4 disease (0% versus 18%, P < 0.0001). Further research is needed to investigate the reasons for the increasing incidence of neuroblastoma.
