Publisher's Note

The June 20, 2006 article by van den Bent et al entitled, “Adjuvant Procarbazine, Lomustine, and Vincristine Improves Progression-Free Survival but Not Overall Survival in Newly Diagnosed Anaplastic Oligodendrogliomas and Oligoastrocytomas: A Randomized European Organisation for Research and Treatment of Cancer Phase III Trial” (J Clin Oncol 24:2715–2722, 2006) was published online with an error. In the full-text version, Figures 2 and 3 were transposed; Figure 2 should have shown the results for overall survival and Figure 3 the results for progression-free survival. This has been corrected as of September 7, 2006. The figures in the PDF version are correct as published.
