What is Hormone Therapy for Prostate Cancer?

Prostate cancer is a significant health concern for men, and understanding treatment options is crucial. Hormone therapy, also known as androgen deprivation therapy (ADT), is a cornerstone treatment for prostate cancer, particularly when the cancer has spread beyond the prostate gland or when other treatments aren't suitable. This blog provides a comprehensive overview of hormone therapy for prostate cancer, with a focus on aspects relevant to patients in India.

In essence, hormone therapy aims to slow down or stop the growth of prostate cancer cells by reducing the levels of male hormones (androgens), primarily testosterone, in the body. Prostate cancer cells rely on these hormones to grow and thrive. By either lowering androgen production or blocking their effects, hormone therapy effectively starves the cancer cells, hindering their progression.

Why is Hormone Therapy for Prostate Cancer Performed?

Hormone therapy is used in various scenarios in the management of prostate cancer. Here's a breakdown of its key applications:

• Managing Advanced Cancer: It is frequently a first-line treatment for advanced prostate cancer, where the cancer has spread (metastasized) to other parts of the body. In such cases, hormone therapy can significantly slow down the cancer's growth and improve the patient's quality of life.

• Combination Therapy: Hormone therapy is often combined with other treatments, such as radiation therapy, to improve their effectiveness. This is especially common for early and locally advanced prostate cancer (where the cancer is confined to the prostate gland or nearby tissues). The hormone therapy shrinks the tumor, making it easier for radiation to target and destroy the cancer cells.

• Neoadjuvant Therapy: In some cases, hormone therapy is given before surgery or radiation (neoadjuvant therapy) to shrink the tumor and make the primary treatment more effective, particularly for patients with intermediate- or high-risk localized prostate cancer.

• Adjuvant Therapy: Hormone therapy can also be administered after surgery or radiation (adjuvant therapy) to kill any remaining cancer cells and reduce the risk of recurrence.

• Palliative Care: Even if a cure isn't possible, hormone therapy can help improve symptoms of advanced prostate cancer, such as bone pain or urinary problems, providing palliative care and enhancing the patient's comfort.

• Alternative to Surgery/Radiation: In certain situations, hormone therapy may be preferred over surgery or radiation, especially if the patient isn't healthy enough to undergo these procedures or if they prefer a less invasive treatment approach.

• Cancer Recurrence: If cancer returns after initial treatment like surgery or radiation, hormone therapy is often used to manage the recurrence.

In summary, hormone therapy is considered when:

• Cancer has spread outside the prostate gland.
• After surgery or radiation, if the cancer returns.
• To shrink a tumor before surgery or radiation.
• If a patient isn't healthy enough for surgery or radiation.
• If a patient prefers hormone therapy over surgery/radiation.

Types of Hormone Therapy:

There are several different types of hormone therapy, each working in a slightly different way to lower androgen levels or block their effects:

• Androgen Deprivation Therapy (ADT): This is the most common type of hormone therapy and aims to block testosterone production in the testicles. There are several ways to achieve this:

  • LHRH Agonists (Luteinizing Hormone-Releasing Hormone Agonists): These medications (e.g., goserelin, leuprolide, histrelin, triptorelin) are injected or implanted and work by initially stimulating, then ultimately suppressing, the production of testosterone in the testicles.

  • LHRH Antagonists: These medications (e.g., degarelix) also stop testosterone production but work more directly and don't cause the initial testosterone surge that can occur with LHRH agonists.

  • Orchiectomy: This is a surgical procedure involving the removal of the testicles, which are the primary source of testosterone production. It is a permanent form of androgen deprivation.

• Anti-Androgen Therapy: These medications (e.g., flutamide, bicalutamide, nilutamide) prevent testosterone from binding to receptors on prostate cancer cells, effectively blocking its effects. They don't stop the production of testosterone but prevent it from stimulating cancer growth.

• Combined Androgen Blockade (CAB): This involves combining androgen deprivation (through surgery or LHRH agonists/antagonists) with an anti-androgen. The goal is to block testosterone production and prevent any remaining testosterone from affecting prostate cancer cells.

• Other Hormonal Agents: These are newer hormonal therapies that work through different mechanisms:

  • Abiraterone: This medication blocks the production of androgens by the adrenal glands and the prostate cancer cells themselves. It's taken orally, usually with prednisone.

  • Enzalutamide, Apalutamide, Darolutamide: These are androgen receptor inhibitors that block the action of testosterone on prostate cancer cells. They are typically used when cancer no longer responds to traditional hormone therapy.

Preparation for Hormone Therapy for Prostate Cancer

Proper preparation is essential for ensuring the safety and effectiveness of hormone therapy. Here's what you can expect:

• Consultation: The first step is a thorough consultation with your oncologist. This is an opportunity to discuss the benefits and risks of hormone therapy, as well as alternative treatment options. Don't hesitate to ask questions and express any concerns you may have.

• Medical History: Your doctor will need a complete medical history, including any existing medical conditions, medications you are taking (including over-the-counter drugs and supplements), and any allergies you have.

• Physical Exam: A physical exam will be performed to assess your overall health.

• Baseline Tests: Before starting hormone therapy, you will likely need several blood tests to assess your hormone levels, kidney and liver function, and complete blood count. A Prostate-Specific Antigen (PSA) test will be performed to establish a baseline PSA level. Bone density scans may also be done, since hormone therapy can weaken bones.

• Lifestyle Considerations: Discuss any lifestyle factors that may affect treatment, such as smoking, alcohol consumption, and diet. Your doctor may recommend certain lifestyle changes to help manage side effects.

• Informed Consent: You will be asked to sign a consent form, indicating that you understand the risks and benefits of hormone therapy and agree to proceed with the treatment.

The Hormone Therapy for Prostate Cancer Procedure

The administration of hormone therapy depends on the specific type of therapy chosen:

• LHRH Agonists/Antagonists: These medications are typically administered via injection, either subcutaneously (under the skin) or intramuscularly (into the muscle). The frequency of injections varies depending on the specific medication, ranging from monthly to every three or six months. These injections are usually administered by a nurse or doctor in a clinic or hospital setting.

• Anti-Androgens: These medications are taken orally, usually once or twice a day. It's important to follow your doctor's instructions carefully and take the medication at the same time each day.

• Abiraterone, Enzalutamide, Apalutamide, Darolutamide: These are also oral medications taken daily. Abiraterone must be taken on an empty stomach, at least one hour before or two hours after a meal.

• Orchiectomy: This is a surgical procedure performed under anesthesia. It involves making an incision in the scrotum and removing the testicles. It is a relatively simple and quick procedure, and most patients can go home the same day.

• Monitoring: During hormone therapy, regular monitoring is crucial. Your doctor will monitor your PSA levels regularly (usually every few months) to see if the treatment is working. A fall in PSA usually indicates that the treatment is effective. They will also monitor you for any side effects and adjust the treatment plan as needed.

Understanding Results

The primary goal of hormone therapy is to slow down or stop the growth of prostate cancer. The effectiveness of the treatment is typically assessed by monitoring PSA levels and by evaluating any changes in the size of the tumor or the spread of the cancer.

• Slowing Cancer Growth: Hormone therapy can effectively slow the growth of prostate cancer and shrink tumors. This can lead to improved symptoms and a better quality of life.

• Symptom Relief: It can alleviate symptoms, especially in advanced cases, such as bone pain, urinary problems, and fatigue.

• PSA Levels: A significant drop in PSA levels is generally a good indication that the treatment is working.

• Resistance: Over time, prostate cancer can become resistant to hormone therapy. This is called castration-resistant prostate cancer (CRPC). When this happens, the cancer cells no longer respond to the effects of hormone therapy. Other treatments, such as chemotherapy or newer hormonal agents, may be needed at this stage.

Side Effects and Their Management:

It's important to be aware of the potential side effects of hormone therapy and how to manage them. Common side effects include:

• Fatigue: This is a very common side effect. Regular exercise, adequate sleep, and a healthy diet can help manage fatigue.
• Decreased Libido: Hormone therapy can significantly reduce sexual desire.
• Hot Flashes: These are sudden feelings of intense heat, often accompanied by sweating. They can be managed with medication or lifestyle changes, such as avoiding caffeine and alcohol.
• Erectile Dysfunction: This is a common side effect. Medications like sildenafil (Viagra) or tadalafil (Cialis) can help.
• Weight Gain: Hormone therapy can lead to weight gain, particularly around the abdomen. A healthy diet and regular exercise can help manage weight.
• Loss of Muscle Mass: Hormone therapy can cause muscle loss. Resistance training (weightlifting) can help maintain muscle mass.
• Osteoporosis (Weakening of Bones): Hormone therapy can weaken bones, increasing the risk of fractures. Regular bone density scans are recommended, and medications like bisphosphonates can help strengthen bones.
• Mood Changes: Hormone therapy can affect mood and cause depression or anxiety. Talking to a therapist or counselor can be helpful.
• Cognitive Changes: Some men experience cognitive changes, such as memory problems or difficulty concentrating.

Discuss any side effects you experience with your doctor. Many side effects can be managed with medication, lifestyle changes, or supportive care.
