Results: the aged-adjusted incidents rate of central nervous system tumors in childhood and adolescent patients in Girona was 41.8 per million-person-years during 23 years of observation. The majority of these tumors were found in boys with age-adjusted incidence rate of 44.0in comparison to 39.6 in girls with a sex ratio Male/Female: 1.1.
