(A) Overall survival according to proposed risk groups. Survival from date of first intra-arterial/blood-brain barrier disruption treatment stratified by age and Karnofsky performance score (KPS). Low risk, age younger than 60 years with KPS ≥ 70 (47 patients); moderate risk, age older than 60 years with any KPS or age younger than 50 years with KPS less than 70 (89 patients); and high risk, age 50 to less than 60 years with KPS less than 70 (13 patients). Symbols on lines indicate censored observations. (B) Progression-free survival according to proposed risk groups. Progression-free survival from date of first intra-arterial/blood-brain barrier disruption treatment stratified by age and KPS. Low risk, age 50 to less than 60 years with KPS greater than 70, or age less than 50 years with any KPS (65 patients); moderate risk, age ≥ 60 years with any KPS (71 patients); and high risk, age 50 to less than 60 years with KPS less than 70 (13 patients). Symbols on lines indicate censored observations.
