| Abstract |
We studied the correlation between epidermal growth factor receptor (EGFR) and the tumor stem cell markers CD44/CD24 in breast invasive ductal carcinoma (BIDC) and their relationship with prognosis. We analyzed the clinical data of 139 BIDC cases retrospectively, detecting EGFR, CD44, and CD24 expressions in tumor tissue using immunohistochemistry. The proportion of EGFR-, CD44-, and CD24-positive cases was 59.0, 62.3, and 30.9 %, respectively. The proportion of CD44-positive [76.9 % (p < 0.05)] and EGFR-positive [67.2 % (p = 0.108)] cases in the triple-negative breast cancer (TNBC) group was higher than that of the non-TNBC group. In the non-TNBC group, 36.5 % was CD24-positive, higher than that in the TNBC group but not statistically significant. The proportion of CD44-positive cases was significantly higher in the EGFR-positive group than in the EGFR-negative group (p = 0.017). EGFR-positive cases were significantly correlated with premenopausal status (p = 0.036), distant metastasis (p = 0.018), and estrogen receptor-negative status (p = 0.020). CD44-positive status was significantly correlated with human epidermal growth receptor 2 (HER2)-negative (p = 0.023), estrogen receptor-negative (p = 0.021), and progesterone receptor-negative status (p = 0.004). CD24-positive status was significantly correlated with HER2-positive status (p = 0.001). Kaplan-Meier survival analysis showed that TNBC patients had shorter survival. EGFR-positive and CD44-positive status were both correlated with shorter survival in the lymph node- and HR-negative groups, while CD24 positive was significantly correlated with poor survival in lymph node-negative and HR-positive patients. EGFR and CD44 expressions have a significantly positive correlation (p = 0.017) in BIDC. Patients both EGFR and CD44 positive had the worst outcome. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 06 December 2014.
All research outputs
#18,385,510
of 22,772,779 outputs
Outputs from Medical Oncology
#793
of 1,287 outputs
Outputs of similar age
#262,129
of 361,891 outputs
Outputs of similar age from Medical Oncology
#17
of 50 outputs
Altmetric has tracked 22,772,779 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,287 research outputs from this source. They receive a mean Attention Score of 3.0. This one is in the 25th percentile – i.e., 25% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 361,891 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 16th percentile – i.e., 16% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 50 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 60% of its contemporaries.
