Erratum: “Alterations in the TOP2A and HER2 Genes: Association with Adjuvant Anthracycline Sensitivity in Human Breast Cancers” by Slamon and Press [ J Natl Cancer Inst 2009; 101(9): 615–618 ]. The spacing in columns 2, 4, 5, and 7 of Table 1 was altered during typesetting such that the data were incorrectly displayed in each row. The correct version of Table 1 appears below. The Journal and the authors regret the error.
