Androgen Deprivation Therapy

Meaning

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.

Context

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.

Significance

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.

Mechanism

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.

Application

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.

Metric

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.

Risk

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.
