What is the Origin of Androgen Deprivation Therapy (ADT)?

The foundation of ADT dates back to the early 1940s with the pioneering work of Charles Huggins, who demonstrated that prostate cancer was androgen-dependent, leading to his Nobel Prize. Huggins' work initially involved surgical castration, or orchiectomy, to remove the primary source of androgens. Pharmacological methods, which constitute modern ADT, were later developed to achieve chemical castration, offering a non-surgical alternative to achieve the same therapeutic goal.

What is the Mechanism of Androgen Deprivation Therapy (ADT)?

ADT operates by disrupting the hypothalamic-pituitary-gonadal axis, the hormonal feedback loop that controls androgen production. Luteinizing Hormone-Releasing Hormone (LHRH) agonists or antagonists are commonly used to suppress Luteinizing Hormone (LH) release from the pituitary gland, thereby halting the signal to the testes to produce testosterone. Additionally, anti-androgens may be used to block the binding of any remaining androgens to the androgen receptor on target cells.

Androgen Deprivation Therapy (ADT)

Meaning

Androgen Deprivation Therapy, or ADT, is a clinical treatment strategy designed to reduce the levels of androgens, such as testosterone and dihydrotestosterone, in the body. This therapeutic approach is primarily utilized in the management of androgen-sensitive cancers, most notably prostate cancer. The rationale behind ADT is that many prostate cancer cells require androgens for growth and survival. By significantly lowering these hormone concentrations, the therapy aims to slow disease progression and reduce tumor burden.

A complex, textured form, potentially a dysfunctional endocrine gland or cellular structure, is shown with translucent white currants representing precise bioidentical hormones. A crystalline element signifies peptide protocols or transdermal delivery. This visualizes hormone optimization for metabolic health, addressing hypogonadism or perimenopause, supporting cellular repair and reclaimed vitality through evidence-based medicine.

How Do Estrogen Receptor Subtypes Influence Prostatic Growth?

Estrogen receptor subtypes ERα and ERβ act as a cellular switch, directing prostatic growth or restraint to maintain gland health.
