title: [Prognostic significance of pretreatment CT scans in supratentorial astrocytomas receiving radiotherapy].
abstract: Pretreatment brain CT scans of 61 patients receiving radiation and chemotherapy for supratentorial gliomas (23 low-grade astrocytomas, 21 grade III astrocytomas and 17 glioblastomas) were reviewed, and their prognoses were analyzed. Almost all gliomas with no CEA (contrast enhanced area) were low-grade, and their prognosis was promising. Benign and malignant gliomas with regular CEA were found in equal proportions, and their prognosis was relatively good. A majority of cases with irregular or ring-like CEA were malignant, and their prognosis was extremely poor.
