What is the Origin of Androgen Suppression?

The clinical application of androgen suppression dates back to the foundational work of Huggins and Hodges in the 1940s, who demonstrated that removing or blocking androgens could cause prostate tumors to regress. This established the principle that prostate cancer is an androgen-dependent disease. The modern pharmacological methods have evolved from surgical castration to medical castration using synthetic agents that modulate the hypothalamic-pituitary-gonadal axis.

What is the Mechanism of Androgen Suppression?

The mechanism of suppression is multifaceted, encompassing several clinical approaches to minimize androgen receptor (AR) activation. Methods include surgical orchiectomy to eliminate testicular testosterone production or medical castration using GnRH agonists or antagonists to downregulate pituitary hormone release. Additionally, antiandrogens are administered to competitively block the binding of any remaining androgens to the AR on the cancer cell surface. Collectively, these strategies obstruct the AR-driven transcription that is essential for the growth and survival of androgen-dependent prostate cancer cells.

Androgen Suppression

Meaning

Androgen Suppression is a targeted antihormone therapeutic strategy employed to drastically reduce the functional activity of androgens within the body, most notably utilized in the treatment of androgen-sensitive prostate cancer. This intervention aims to achieve castrate levels of circulating testosterone, thereby starving the malignant cells of the primary hormones that fuel their growth and proliferation. The clinical goal is to slow disease progression, reduce tumor burden, and improve overall survival in patients with advanced or high-risk localized disease. This treatment modality is also referred to as Androgen Deprivation Therapy (ADT).
