CT prognostic criteria of survival after malignant glioma surgery

The serial pre- and postoperative computed tomographic (CT) scans of 115 patients entered in the Cooperative Brain Tumor Study between 1975 and 1982 were analyzed in order to define CT prognostic criteria and to test the hypothesis that radical glioma surgery prolongs patient survival. The CT parame...

Description
Summary:The serial pre- and postoperative computed tomographic (CT) scans of 115 patients entered in the Cooperative Brain Tumor Study between 1975 and 1982 were analyzed in order to define CT prognostic criteria and to test the hypothesis that radical glioma surgery prolongs patient survival. The CT parameters of mass size, associated edema, and intensity of enhancement were quantitated on all scans. Clinical parameters evaluated included gender, age, length of survival, and useful (Karnofsky greater than 30) survival. Data analyses indicated postoperative residual tumor burden was inversely related to length of survival (p less than 0.01). Postoperative associated edema and intensity of image enhancement were also of prognostic value and showed an inverse relation to survival. Younger patients proved more likely than older patients to attain long-term survival. Residual tumor burden of less than 45 mm diameter on postoperative CT scans was associated with 70% chance of long-term survival. These findings support the radical surgical management of glioma.
