Improving outcome of malignant brain tumours in very young children: a population‐based study in Finland during 1975‐93

Abstract

Sixty-four children with malignant brain tumours diagnosed at less than 3 years of age were reported to the Finnish Cancer Registry from 1975 to 1993. The survival rate has improved significantly: the 5-year survival rate was 26% for all children, 13% for children diagnosed during 1975-85 (n = 30) and 40% for those diagnosed during 1986-93 (n = 34). Of the surviving children in 1986-93, 43% were categorized in Bloom's group I or II and could lead active lives without major disabilities. The remaining children had severe neurologic late complications, such as hemiplegia, intractable seizures, and mental retardation.
