  1. Epidemiological study of primary intracranial tumors in childhood : A population-based survey in Kumamoto Prefecture, Japan. Commentary.

    Article - En anglais

    Between 1989 and 1995, we diagnosed primary intracranial neoplasms in 79 children younger than 15 years.

    All of them belonged to a well-defined population residing in Kumamoto Prefecture, Japan.

    Of the tumors, 64 (81.0%) were confirmed microscopically.

    The age-adjusted annual incidence rate was 34.3 cases per million child population.

    There was a marked difference in the incidence rate between boys (47.1) and girls (22.05).

    The age-specific annual incidence per million was 24.3 cases for the 0-to 4-year age group, 46.7 for the 4-to 9-year age group and 30.8 for the 10-to 14-year age group.

    The highest incidence rate was seen in 5-to 14-year-old boys (53.5), the lowest in 10-to 14-year-old girls (7.1).

    The most common tumors were astrocytomas (41.8%), with an incidence of 14.52 per million, followed by germ cell tumors (15.1%), with an incidence of 6.24 per million, craniopharyngiomas (15.1%), incidence 5.25 per million, ependymomas (6.3%), incidence 2.19 per million, and medulloblastomas (6.2%), incidence 2.19 per million.

    The distribution of tumor types varied with patient age at the time of diagnosis.

    Although no germ cell tumors were encountered in the 0-to 4-year age group, in the 10-to 14-year age group, they comprised about one third of all tumors.

    In contrast, while craniopharyngiomas were rare in the 10-to 14-year age group, they made up more than 22% in the 0-to 4-year age group. (...)
