Are Thyroid Hormone and Tumor Cell Proliferation in Human Breast Cancers Positive for HER2 Associated?
Article in International journal of endocrinology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective. This study investigated whether thyroid hormone (TH) levels are correlated to cell proliferation (Ki67), in euthyroid breast cancer patients. Design and Methods. 86 newly diagnosed breast cancer patients with estrogen receptor (ER) positive tumors, who referred for surgery, were included in the study. Results. FT3, FT4, and TSH were within normal range. No correlation was seen between Ki67 and FT3 (r = -0.17, P = 0.15), FT4 (r = -0.13, P = 0.25), or TSH (r = -0.10, P = 0.39) in all patients studied. However, subgroup analysis showed that, in HER2(+) patients, a negative correlation existed between FT3 levels and Ki67 (r = -0.60 and P = 0.004) but not between Ki67 and FT4 (r = 0.04 and P = 0.85) or TSH (r = -0.23 and P = 0.30). In HER2(-) patients, there was no significant correlation between Ki67 and FT3 (r = -0.06, P = 0.67), FT4 (r = -0.15, P = 0.26), or TSH (r = -0.09, P = 0.49). Phospho-p44/total p44 ERK levels were found to be increased by 2-fold in HER2(+) versus HER2(-) tumors. No difference was detected in phospho-p42/total p42 ERK levels. Conclusions. TH profile is not altered in patients with newly diagnosed breast cancer. However, FT3 levels, even within normal range, are negatively correlated with cell proliferation in HER2(+) breast cancer tumors. This response may be due to the interaction between ERK and TH signaling.
