Fig. 2. Kaplan-Meier survival curves for patients with glioblastoma. A : Age <50 vs. age ≥50. B : KPS ≥70 vs. KPS <70. C : Extent of surgical resection. D : Method of adjuvant treatment. E : Methylation status of the MGMT promoter analyzed by methylation-specific PCR. F : Methylation status of the MGMT promoter analyzed by pyrosequencing. G : Methylation status of MGMT promoter in patients who were treated with concurrent temozolomide chemoradiotherapy (TMZ CCRT). H : Extent of methylation of the MGMT promoter analyzed quantitatively by pyrosequencing.
