Erratum: Longitudinal Change in Cardiac Function After Doxorubicin and Dexrazoxane: A Report From Children's Oncology Group ALTE11C2 (J Clin Oncol, (10.1200/JCO-26-00260))

The article by Mobley et al titled “Longitudinal Change in Cardiac Function After Doxorubicin and Dexrazoxane: A Report From Children’s Oncology Group ALTE11C2” (J Clin Oncol 10.1200/JCO-26-00260) was published online August 6, 2026, with errors. In Figure 2, all panels, the x-axis read “Time Since Treat- ment Began (months)” but should have read “Time Since Treatment Began (years).” On page 4, the first sentence of the second paragraph should read, “When examining the data for the short-term (1 to <10 years after diagnosis) in comparison with the longer-term time period (≥10 years after diagnosis; Appendix Table A1, online only), the most notable differences were that the proportion of men was higher in the short-term follow-up period (71%) compared with the long-term period (51%).” On page 5, the last sentence of the first paragraph should read, “Generally, more recent echocardiograms had more evaluable LV ejection fraction data (eg, 79% [n 5 603] of studies ≥5 years post-treatment) reflecting historic pedi- atric echocardiography practice that focused on measuring fractional shortening than obtaining views that enabled measurements of ejection fractions. 29 ” This has been corrected as of August 24, 2026. Journal of Clinical Oncology apologizes for the errors.
