Kaplan-Meier plots depicting survival after relapse of 63 patients treated with (“BCNU”) or without (“control”) BCNU after recurrent GBM. Note that the association of BCNU treatment with an improved survival after relapse (a) was even more pronounced in patients with other therapies than BCNU at tumor recurrence (“with” compared to “w/o” (without); b) as well as in patients with hypermethylated MGMT promoter (c) while patients with unmethylated MGMT promoter did not seem to benefit from BCNU treatment (d)
