Correction to “Chemotherapy for Post-Menopausal Women With Early Breast Cancer Seems Not to Result in Clinically Significant Changes in Thyroid Function”

Marina D, Buch-Larsen K, Gillberg L, et al. Chemotherapy for post-menopausal women with early breast cancer seems not to result in clinically significant changes in thyroid function. Cancer Med. 2024; 13:e70015. doi:10.1002/cam4.70015

The authors have unfortunately identified an error in the Methods section (page 3 of 12), where we incorrectly described the assay as “immunohistochemistry” instead of the correct term “immunoassay.” The accurate sentence should read “Thyroid parameters (s-TSH, s-TT4, s-FT4, s-TT3) were analyzed by immunoassay; s-TgAb and s-TPOAb were analyzed by immunofluorometry, whereas s-TRAb was analyzed by electrochemiluminescence immunoassay.”

Additionally, this error appears two times in the Discussion section (page 9 of 12), where “immunohistochemistry” should also be replaced with “immunoassay.” The accurate sentences should read:

“Our study group conducted an analysis of thyroid hormones using immunoassay, which was the most affordable assay and readily available at a low cost in our department.”

“It has been documented that free thyroid hormones measured by LC–MS/MS correlate better with log-transformed TSH than those measured by immunoassay, particularly in certain patient groups.”

Furthermore, in Supplementary Table S1 (page 3 out of 12), the assay type for the measurements of TSH, TT4, FT4, and TT3 should be corrected again from “immunohistochemistry” to “immunoassay.” The corrected table can be found in the online Supporting Information.

We sincerely apologize for this error.
