The April 20, 2009, article by Galanis et al, entitled “Phase II Trial of Vorinostat in Recurrent Glioblastoma Multiforme: A North Central Cancer Treatment Group Study” (J Clin Oncol 27:2052–2058, 2009), contained errors.
In the Discussion section, the last sentences of the fourth and fifth paragraphs referred to the North American Brain Tumor Coalition, whereas it should have been the North American Brain Tumor Consortium.
The online version has been corrected in departure from the print.
