title: Correction: Survivin as a Prognostic Marker for Urothelial Carcinoma of the Bladder: A Multicenter External Validation Study.
abstract: In this article (Clin Cancer Res 2009;15:7012–9), which was published in the November 15, 2009, issue of Clinical Cancer Research (1), the study support was incorrectly listed as "NIH T32 training grant T32CA082088." The article did not receive NIH support. The correct support listing should read as follows: "Departmental support from the University of Texas Southwestern Medical Center." The authors regret this error.
