(a) Median survival according to RPA class following WBRT [26]. (b) RTOG Graded Prognostic Assessment (GPA) is felt to be a more sensitive tool for predicting outcomes in BrM patients. They are assigned a score of 0, 0.5, or 1 for each of 4 characteristics. The sum of the score predicts median survival both as a whole (RTOG MS) and with therapy such as WBRT ± SRS [27]. (c) Disease Specific GPA [28].
