“Stage I Seminoma: Adjuvant Treatment is Effective but is it Necessary?” by Peter Chung and Padraig Warde Anthony; and “Assessing the Quality and Value of Quality-of-Life Measurement in Breast Cancer Clinical Trials” by Patricia A. Ganz [ J Natl Cancer Inst 2011;103(3): 194-199 ]. The page numbers for the editorials are incorrectly shown as 194–199. They should indeed be 164–169.

The publisher would like to apologize for this error.
