HER2-positive pure mucinous breast carcinoma: A case …
First, ER(+), PR(−) breast cancer is a highly invasive type. The lack of PR is correlated with low concentrations of serum estrogen, low levels of nuclear ER, and crosstalk between HER2 and membranous ER. ER(+), PR(−) breast cancers usually have higher
Triple Negative (ER-/PR-/her2-) Breast Cancer Prognosis …
· Triple negative refers to breast cancer that is estrogen receptor negative (ER-), progesterone receptor negative (ER-), and HER2/neu negative (HER2-). In other words, triple negative breast cancer does not express receptors for estrogen or progesterone and does not
Estrogen Receptor, Progesterone Receptor, and HER2 …
In a similar fashion to ER and PR, HER2 has been investigated for its prognostic value in endometrial cancer, but its prognostic significance also remains controversial [14, 22]. Contrary to ER and PR expression found predominantly in the cell nucleus, HER23).
ER/PR HER2, HER2
ER and PR status is determined by the percentage of stained tumor cells, according to ASCO/CAP guidelines. HER2 (c-erbB-2) expression by IHC is measured in accordance with CAP/ASCO Guidelines for both prognostic and therapeutic purposes in breast and gastroesophageal carcinomas.

Breast cancer classification
Receptor status was traditionally considered by reviewing each individual receptor (ER, PR, her2) in turn, but newer approaches look at these together, along with the tumor grade, to categorize breast cancer into several conceptual molecular classes that have
Phenotypic discordance between primary and metastatic …
· Expression of hormone receptor (HR) for estrogens (ER) and progesterone (PR) and HER2 remains the cornerstone to define the therapeutic strategy for breast cancer patients.

Results Overall, 21696 women with N2-3 tumors were included from 284073 patients. T stage, nodal stage (N stage), ER, PR, HER2 and grade were all independent prognostic factors. Notably, HER2 positivity was correlated with better BCSS possibly due to the

ER/PR/Her2 Receptor studies in Breast Cancer
Breast Cancer Receptors Breast cancers can over-express the estrogen (ER), progesterone (PR) and Her2/neu receptors which can have prognostic impact for the patient as there are therapeutic options for these tumors. Tumors can be tested for ER/PR or Her2 protein expression via either immunohistochemical (IHC) staining. HER2 …

All About ER Positive, HER2 Negative Breast Cancer
· For example; in ER positive/HER2 negative breast cancer, tumors that are ER positive are much more likely to respond to treatments that block estrogen. Treatment possibilities include selective estrogen-receptor response modulators (SERMs), aromatase inhibitors, estrogen-receptor downregulators (ERDs) and luteinizing hormone-releasing hormone agents (LHRHs).
Cell-specific regulation of proliferation by …
· Ano1 overexpression was associated with longer overall survival (OS) in breast cancer with the low expression of Ki67, especially in ER-positive, PR-positive, and HER2-negative breast cancer. Multivariate Cox regression analysis showed that Ano1 overexpression was a prognostic factor for longer overall survival in ER-positive, PR-positive, or HER2-negative patients with the low expression of Ki67.
Quality statement 4: ER and HER2 receptor status
If breast cancer recurs, the ER and HER2 status of the tumour may be different from that of the original primary tumour. Therefore recurrent tumours (either at the site of the primary tumour or metastatic tumours) should be assessed for their ER and HER2 status, if a change in receptor status will lead to a change in management.
