The methylation status of the O6‐methylguanine‐methyltransferase promoter (MGMTP) was evaluated in 68 low‐grade gliomas treated by neoadjuvant temozolomide. Methylated MGMTP was detected in 63 of 68 (92.6 %) patients and was a favorable predictor of progression‐free survival as compared with unmethylated MGMTP tumors ( p < 0.0001). Assessment of MGMTP status could help identifying low‐grade gliomas patients more likely to respond to chemotherapy or to benefit from MGMT depletion strategies. Ann Neurol 2006;60:740–743
