title: Malignancy grade and long-term survival in brain tumours of infancy and childhood.
abstract: 281 histologically verified brain tumours in children were revised and reclassified according to degree of histological malignancy. Survival graphs based on 100 per cent follow-up after 15-40 years show that, of those who survived for more than 1 month after diagnosis and possible operation, 40 per cent were still alive more than 15 years later. There was a clear correlation between survival and degree of malignancy. Sixty-five per cent of those with tumours of malignancy grade I and only 3 per cent of those with malignancy grade IV were alive after 15 years.
