What is the Origin of Hormone Receptor-Positive?

This term originates from the field of molecular pathology, following the discovery that certain cancers, particularly breast and prostate, are hormone-dependent. The ability to assay for the presence of these nuclear receptors in tumor tissue became a standard diagnostic procedure in the late 20th century. The positive result signifies a targetable biological pathway for therapeutic intervention.

What is the Mechanism of Hormone Receptor-Positive?

The mechanism involves the hormone, such as estradiol, entering the cell and binding to the nuclear receptor (ER or PR), which then dimerizes and translocates to the cell nucleus. Once in the nucleus, the activated receptor complex binds to specific DNA sequences, acting as a transcription factor to promote the expression of genes responsible for cell proliferation and survival. Hormone-blocking drugs work by competitively binding to the receptor or by inhibiting hormone synthesis, thereby preventing this growth-stimulatory cascade.

Hormone Receptor-Positive

Meaning

Hormone Receptor-Positive is a clinical designation, primarily used in oncology, to describe cancer cells that express functional receptors for specific hormones, most commonly estrogen (ER) or progesterone (PR). This expression indicates that the tumor’s growth is stimulated, or driven, by the binding of these circulating hormones to their respective receptors on the cell surface. The presence of these receptors is a critical prognostic factor and determines the suitability of hormone-blocking therapies, which aim to starve the cancer cells of their growth-promoting signal.
