Abstract
This paper describes a retrospective population‐based study of neuroblastoma in the West Midlands Health Authority Region—childhood population 1.12 million (OPCS, census 1981)—in which 239 cases were diagnosed between 1st January 1957 and 31st December 1988. The age standardised rate of tumour incidence has remained constant at 7.2 cases per million children per year. The median age at diagnosis was 2 years with 18% of children presenting before the age of 6 months. Fifty children (21%) presented before the age of one year, and for this group of children, the prognosis has improved significantly over the 32‐year period (10 year survival increasing from 63% in 1957–67 to 87% in 1978–88), whereas for the 189 (79%) children who presented after one year of age, the prognosis has remained very poor during the study period (10 year survival 1957–67 = 9.5%, 1978–88 = 8.5%). This study supports the need for a prospective study of mass screening at several intervals rather than only at 6 months of age.
