List of hormonal cytostatic antineoplastic agents

Hormonal Cytostatic Antineoplastic Agents are a class of antineoplastic agents that work by interfering with the hormonal environment of cancer cells, which is essential for their growth and proliferation. These agents are particularly effective in treating cancers that are hormone-dependent, such as certain types of breast cancer and prostate cancer. This article provides an overview of the various hormonal cytostatic antineoplastic agents, categorized by their mechanism of action and the types of cancer they are commonly used to treat.

Types of Hormonal Cytostatic Antineoplastic Agents

Estrogen Receptor Modulators

Estrogen receptor modulators are compounds that act on the estrogen receptors in cells. They can either block or activate estrogen receptors, depending on the target tissue. In the context of cancer treatment, they are used primarily to block the effects of estrogen on breast cancer cells.

• Tamoxifen
• Raloxifene
• Fulvestrant

Aromatase Inhibitors

Aromatase inhibitors reduce the production of estrogen in the body by inhibiting the aromatase enzyme, which converts androgens into estrogens. These are particularly useful in treating postmenopausal women with breast cancer.

• Anastrozole
• Letrozole
• Exemestane

Progestins

Progestins are synthetic forms of the hormone progesterone. They can slow the growth of certain cancers by interacting with progesterone receptors in the cells.

• Megestrol acetate
• Medroxyprogesterone acetate

Androgen Deprivation Therapy (ADT)

Androgen deprivation therapy, also known as androgen suppression therapy, aims to reduce levels of male hormones, androgens, in the body to prevent them from stimulating the growth of prostate cancer cells.

• Gonadotropin-releasing hormone (GnRH) agonists

 * Leuprolide
 * Goserelin

• GnRH antagonists

 * Degarelix

Selective Androgen Receptor Modulators (SARMs)

Selective androgen receptor modulators (SARMs) are compounds that selectively inhibit or stimulate the androgen receptors in different tissues. They are under investigation for their potential to treat various medical conditions, including certain cancers.

• Enzalutamide
• Apalutamide

Applications in Cancer Treatment

Hormonal cytostatic antineoplastic agents are primarily used in the treatment of hormone-dependent cancers. The most common applications include:

• Breast cancer: Estrogen receptor modulators, aromatase inhibitors, and progestins are commonly used in the treatment of breast cancer.
• Prostate cancer: Androgen deprivation therapy (ADT) and selective androgen receptor modulators (SARMs) are key in treating prostate cancer.

Side Effects

The use of hormonal cytostatic antineoplastic agents can lead to a range of side effects, depending on the specific drug and the individual's response. Common side effects include hot flashes, mood swings, fatigue, and risk of blood clots. Long-term use can also impact bone density and cardiovascular health.

Conclusion

Hormonal cytostatic antineoplastic agents play a crucial role in the treatment of hormone-dependent cancers. By targeting the hormonal pathways that cancer cells rely on for growth, these drugs offer a targeted approach to cancer treatment. Ongoing research continues to expand our understanding of hormone-dependent cancers and the potential of hormonal therapies in their treatment.
