To obtain a more comprehensive view, we integrated methylation data for a sample set consisting of tumor cells derived from 38 glioma patients from this study and our previous study [15] and investigated their associations with MGMT expression, as well as with multiple clinical and demographic parameters, including proliferation index Ki-67, overall survival (OS), long-term survival, progression-free survival (PFS), postoperative Karnofsky Performance Score (KPS), TERT promoter mutations C228T and C250T, TERT SNP rs2853669, age, and sex of the patients. The gene discussed is TERT; the disease is central nervous system cancer.
