Abstract:
:The principal prognostic factors and effect on survival were retrospectively evaluated in 56 adult patients with supratentorial low grade astrocytomas treated between 1967 and 1993. Fifteen factors were evaluated with uni- and multivariate analysis to investigate their importance in predicting the length of survival. The median patient age at presentation was 42 years and the median survival was 5.0 years. The following characteristics were associated with improved patient survival by univariate analysis (p < 0.01): Age group, preoperative Karnofsky scale, and extent of surgery. Age group and Karnofsky scale were significant by multivariate analysis, but not the extent of surgery. Thus the usefulness of cytoreductive surgery in the management remains unclear, but the extent of surgery is determined by the characteristics of the tumor and the potential of the patient. Since 93% of our patients received postoperative radiotherapy, the effect of adjuvant irradiation could not be determined.
