What is the Meaning of Androgen Deprivation Therapy?

Androgen Deprivation Therapy (ADT) is a medical treatment reducing production or blocking action of androgens, such as testosterone. This therapy inhibits growth of androgen-sensitive cells, primarily in prostate cancer, by removing their hormonal stimulus. It is a foundational approach for androgen-dependent malignancies.

What is the Context of Androgen Deprivation Therapy?

Androgens, primarily from testes and adrenal glands, exert effects by binding receptors. In prostate cancer, these hormones stimulate tumor growth. ADT intervenes in endocrine system, suppressing testicular androgen synthesis via HPG axis or directly blocking androgen receptor signaling, disrupting hormonal support.

What is the Significance of Androgen Deprivation Therapy?

ADT is a primary treatment for locally advanced, recurrent, or metastatic prostate cancer. By lowering systemic androgen levels, it slows tumor growth, reduces Prostate-Specific Antigen (PSA) levels, and alleviates cancer-related symptoms. This therapy often improves progression-free and overall survival for selected patients.

What is the Mechanism of Androgen Deprivation Therapy?

ADT disrupts androgen signaling through several mechanisms. LHRH agonists/antagonists suppress pituitary gonadotropin release, reducing testicular testosterone to castration levels. Anti-androgens block androgen binding receptors. Newer agents, like CYP17 inhibitors, inhibit androgen synthesis in tissues, providing comprehensive androgen blockade.

What is the Application of Androgen Deprivation Therapy?

ADT is applied via injectable LHRH analogs and oral anti-androgens or androgen synthesis inhibitors. It serves as standalone treatment for advanced prostate cancer, or combined with radiation for high-risk localized disease, or alongside chemotherapy for aggressive metastatic cases. Protocols are tailored to individual patient characteristics and disease stage.

What is the Metric of Androgen Deprivation Therapy?

ADT efficacy is monitored via biomarkers and clinical assessments. Serum testosterone levels are regularly measured to confirm adequate androgen suppression, targeting castration levels typically below 50 ng/dL. Prostate-Specific Antigen (PSA) levels serve as a crucial tumor marker, with decline indicating therapeutic response. Clinical symptom resolution also assesses disease stability.

What is the Risk of Androgen Deprivation Therapy?

ADT carries potential adverse effects requiring careful clinical oversight. Risks include hot flashes, decreased libido, erectile dysfunction, fatigue, and body composition changes. Long-term use can lead to significant bone mineral density loss, increasing fracture risk, and may contribute to metabolic complications like insulin resistance and heightened cardiovascular risk. Proactive management is essential.
