Cerebellar astrocytomas in children.

摘要: Cerebellar astrocytomas, as a group, carry more favorable prognosis than most other brain tumors, because these neoplasms generally are histologically benign and amenable to extensive resection. However, it is clear that number of factors have an impact on prognosis. In particular, resection extent has been strongly associated with progression-free survival: patients undergoing gross total appear substantially better those incomplete Brainstem invasion, which the factor often precludes complete resection, also less addition, histological features indicative malignancy clearly poor outcome.
