From: Recurrence in oral and pharyngeal cancer is associated with quantitative MGMT promoter methylation
Degree of MGMT promoter methylation. The degree of methylation at the MGMT promoter was determined by pyrosequencing (Pyromark MGMT ID system). Shown are the plots of (A) overall patient survival time (months) and (B) disease-free survival time (months), according to the degree of MGMT methylation (no detectable methylation or a level of methylation either greater than or less than 6.9%).
