Correlation analyses of ABCG2, MGMT and ABCB1 promoter methylation in primary tumors and relapses of 17 GBM patients. (A) Correlation analysis for the median ABCG2 promoter methylation (Spearman’s rank correlation coefficient: 0.804, p < 0.001). (B) Correlation analysis for the median MGMT promoter methylation (Spearman’s rank correlation coefficient: 0.42, p = 0.09). (C) Correlation analysis for the median ABCB1 promoter methylation (Spearman’s rank correlation coefficient: 0.140, p = 0.59).
