Abstract

From 1 January, 1982 until 31 December, 1987 260 adult patients were referred to the Cancer Control Agency of B.C. with high grade supratentorial astrocytomas. Multifocal disease on presentation was present in 17 cases (6.5%). Their survival is poor and whole brain radiotherapy is required. All other cases had unifocal disease, but eight did not receive radiotherapy. The 235 cases who received radiotherapy were subject to univariate and multivariate analyses according to extent of surgery, age, Kernohan and WHO grading, Karnofsky performance status, whole brain treatment, partial brain treatment, total dose and neuroret. Age is an extremely important predictor of survival (P = 0). The pathologic appearance of glioblastoma (WHO grade) as well as the Karnofsky performance status were also important independent factors in predicting survival (P = 0.016, 0.027 respectively) on Cox multivariate analysis. Dose and neurorets were significant factors only in cases where the performance status was not recorded, suggesting that dose was selected according to the patient's condition and age. In this analysis it was found that localized radiation fields may be used rather than whole brain without jeopardizing survival.
