The February 20, 2012 article by Amir et al entitled "Prospective Study Evaluating the Impact of Tissue Confirmation of Metastatic Disease in Patients With Breast Cancer," (J Clin Oncol 30: 587-592, 2012) was published online November 28, 2011 with an error.
Under the Change in Therapy section, the first sentence was given as "Seventeen women (14%; 95% CI, 8.4% to 1.5%) had a change in treatment as compared with the prebiopsy therapeutic plan." However, it should have read as "Seventeen women (14%; 95% CI, 8.4% to 21.5%) had a change in treatment as compared with the prebiopsy therapeutic plan."
This has been corrected as of February 26, 2016. Journal of Clinical Oncology apologizes for the mistake.
