In another man in his 50’s with right temporal GBM with an unmethylated MGMT promotor, an MRI scan after 12 cycles of adjuvant TMZ treatment showed complete remission of the tumor (Fig. 3B, left), and Met-PET demonstrated low uptake (Tmax/Nave, 1.52) (Fig. 3B, middle). The gene discussed is MGMT; the disease is glioblastoma.
