Since estrogen receptor (ER) and progesterone receptor (PR) data were available and HER2 status was not, the researchers categorized the tumors as ER or PR positive (HR positive), or both ER and PR negative (HR negative).

The mice are particularly good models of estrogen receptor - positive tumors (so named because they are fueled by estrogen) that have become resistant to the drugs used to treat them.

But recent work shows that while these cancers lack estrogen receptors, progesterone receptors, and aren't driven by the gene HER2, up to a third of these tumors express the androgen receptor — clinical trials are underway to inhibit the androgen receptor in these tumors in much the same way that the drug Tamoxifen inhibits estrogen receptor in estrogen - receptor - positive breast cancers.

The biopsy of his primary tumor pointed to treatment with anti-HER2 therapy (Herceptin), but tissue from the metastatic biopsy, as well as cfDNA analysis, was negative for HER2 and positive for anti-epidermal growth factor receptor (EGFR) therapy (ABT - 806).

Depending on characteristics such as how many tumor cells, blood vessel cells, and immune cells are touching each other, the tumor microenvironment can nearly triple the chance that a common type of breast cancer (estrogen - receptor positive / HER2 negative) that has reached the lymph nodes will also metastasize, Condeelis and colleagues showed in a 2014 study of 3,760 patients.

Breast cancers are classified as ER - positive or ER - negative according to whether tumors are found to contain estrogen receptors.

Dr. Mack's research has focused primarily on the use of novel antitumor agents in human estrogen receptor negative breast tumor cells, and more recently, on the use of bioflavonoids in the regulation of estrogen receptor positive (ER +) and estrogen receptor negative (ER --RRB- breast tumor cell proliferation.

Although the differing effects of hypoxia reported here are in conflict with previously published data, where no contrasting effect was seen (18 — 20), our data was produced using 13 primary breast cancer samples, as well as established cell lines, and the opposing effects in hormone receptor — positive and negative tumors, measured using multiple in vitro and in vivo CSC assays, were consistent in all cases.

This is supported by recently published data in the New England Journal of Medicine (21), where patients with triple - negative breast cancer were seen to show increased complete pathologic response to bevacizumab treatment, with no detectable tumor at primary or metastatic sites, whereas no improvement was observed in hormone receptor — positive cases.

«We found a strong reduction in the risk of estrogen - receptor - negative [ER --RSB- breast cancer in particular, which is exciting because that type of tumor, while rarer than estrogen - receptor - positive [ER +] tumors, tends to be aggressive.»

A 3rd category is comprised of tumors testing positive for the HER2 receptor.

Well, most breast tumors are estrogen receptor positive, meaning they respond to estrogen; estrogen makes them grow.

Dr. Lee said many times that women with hormone receptor positive breast cancers could especially benefit from natural progesterone supplements because their tumors had progesterone receptors to which the progesterone could bind.
