Treatment of Advanced Prostate Cancer: Comprehensive & Latest Patient Guide
Prostate cancer is a significant health concern for men worldwide, particularly when it advances beyond the early stages. Advanced prostate cancer requires a multifaceted treatment approach by a urologist oncologist to manage the disease and improve the quality of life for patients. As a prostate cancer specialist and urooncologist in India, I aim to provide a detailed understanding of the various treatment options available for advanced prostate cancer, including robotic surgery, radiation therapy, and androgen deprivation therapy (ADT) to help patients choose the best treatment for advanced prostate cancer.
Understanding Advanced Prostate Cancer
Advanced prostate cancer refers to cancer that has spread beyond the prostate gland to nearby tissues, lymph nodes, or distant organs.
It is typically categorized into two main stages:
· Stage 3 : locally advanced prostate cancer – here cancer has spread to surrounding organs like bladder, seminal vesicles, pelvic lymph nodes.
· Stage 4 : metastatic prostate cancer – here the cancer has spread to distal organs. Prostate cancer most commonly spreads to spine. Other common sites of metastasis include lungs, liver abdomen lymph nodes other bones.
Treatment Options for Advanced Stage Prostate Cancer
1. Robotic-Assisted Radical Prostatectomy
Robotic-assisted radical prostatectomy (RARP) is a surgical procedure that involves the removal of the prostate gland using robotic technology. This advanced form of surgery offers greater precision and control to the urologist surgeon, thereby making it a preferred choice for many patients and surgeons.
What is Robotic-Assisted Radical Prostatectomy?
Robotic-assisted radical prostatectomy uses robotic systems, such as the da Vinci Surgical System, to enhance the surgeon's capabilities. The surgeon controls the robotic instruments from a console, providing a 3D high-definition view of the surgical area. The robotic arms offer greater dexterity and precision, allowing for nerve-sparing techniques that can help preserve urinary and sexual function.
Advantages of Robotic-Assisted Radical Prostatectomy
- Enhanced Precision : The robotic system provides superior 3D and high definition(HD) visualization and precision, allowing for more accurate removal of cancerous tissue while sparing erectile nerves and urinary continence structures.
- Minimally Invasive : The procedure involves few small incisions (1cm) in the abdomen, resulting in less blood loss, reduced pain, and quicker recovery times compared to traditional open surgery.
- Improved Outcomes : Studies have shown that RARP is associated with lower complication rates, shorter hospital stays, and better functional outcomes.
Indications for Robotic-Assisted Radical Prostatectomy in Advanced Stage Prostate Cancer
Robotic-assisted radical prostatectomy is typically recommended for patients with localized or locally advanced prostate cancer. It may also be considered for select patients with limited metastatic disease, depending on their overall health and cancer characteristics.
2. Radiation Therapy
Radiation therapy is a common treatment option for advanced prostate cancer, using high-energy rays or particles to destroy cancer cells. There are two main types of radiation therapy: external beam radiation therapy (EBRT) and brachytherapy.
External Beam Radiation Therapy (EBRT)
EBRT involves directing radiation beams at the prostate gland from outside the body. This method is highly precise and can target the cancer while sparing surrounding healthy tissues.
Advantages of EBRT
- Non-invasive : EBRT is a non-surgical treatment option, making it suitable for patients who cannot undergo surgery.
- Effective for Advanced Cancer : EEBRT can be used to treat both locally advanced and metastatic prostate cancer.
- Combination Therapy : EBRT can be combined with other treatments, such as ADT, to enhance its effectiveness.
Disadvantages of EBRT
- Multiple Sessions : Treatment requires multiple sessions over several weeks, which may be inconvenient for some patients.
- Side Effects : Potential side effects include fatigue, urinary issues, bowel problems, and sexual dysfunction.
Brachytherapy
Brachytherapy involves placing radioactive seeds directly into the prostate gland. These seeds emit radiation over a period of time, targeting the cancer cells.
Advantages of Brachytherapy
- High Precision : Brachytherapy delivers radiation directly to the prostate, minimizing exposure to surrounding tissues.
- Shorter Treatment Duration : The treatment is completed in fewer sessions compared to EBRT.
Disadvantages of Brachytherapy
- Invasive Procedure : Brachytherapy requires anesthesia and is an invasive procedure.
- Side Effects : Potential side effects include urinary retention, discomfort, and sexual dysfunction.
3. Androgen Deprivation Therapy (ADT)
Androgen deprivation therapy (ADT) is a cornerstone in the treatment of advanced prostate cancer. It involves reducing the levels of male hormones (testosterone) that stimulates the growth of prostate cancer cells.
What is Androgen Deprivation Therapy?
ADT can be achieved through surgical removal of the testicles (orchiectomy) or, more commonly, through medications that lower androgen levels or block their effects. These medications include luteinizing hormone-releasing hormone (LHRH) agonists, LHRH antagonists, and anti-androgens.
Advantages of ADT
- Effective for Advanced Cancer : ADT is highly effective in controlling the growth of advanced prostate cancer and alleviating symptoms.
- Combination Therapy : ADT is often combined with other treatments, such as radiation therapy or chemotherapy, to enhance its effectiveness.
Disadvantages of ADT
- Side Effects : Long-term use of ADT can lead to significant side effects, including hot flashes, reduced libido, erectile dysfunction, osteoporosis, and cardiovascular issues.
- Hormone Resistance : Over time, most prostate cancer patients become resistant to hormone therapy, necessitating additional treatment options.
Indications for Each Treatment Modality
1. Robotic-Assisted Radical Prostatectomy:
- Indicated for patients with localized or locally advanced prostate cancer.
- Recommended for younger, healthier patients seeking definitive treatment.
- May be considered for select patients with limited metastatic disease.
2. Radiation Therapy:

With treatment, many men with Stage 4 prostate cancer can live for several years. The exact prognosis depends on factors such as overall health, response to treatment, and the extent of cancer spread. Some patients live five years or more with effective treatment.
Without treatment, the prognosis for Stage 4 prostate cancer is generally poorer. Life expectancy may be significantly reduced, often ranging from 6 months to 2 years, depending on the individual's health and rate of cancer progression.
Kegel exercises can be started a few days after prostatectomy, once the urinary catheter is removed. These exercises help strengthen the pelvic floor muscles, which can hasten urinary control and reduce overall incontinence rates of prostatectomy. Some urologist also recommend starting kegels exercise before surgery to get accustomed to the exercise.
The cost of robotic prostatectomy can vary widely, but in the United States, it typically ranges from $10,000 to $20,000, depending on the hospital and the surgeon's fees.
In India, the cost of robotic prostatectomy is generally lower, ranging from INR 3,00,000 to INR 6,00,000 (approximately $4,000 to $8,000), depending on the hospital and the city.
Common medications for erectile dysfunction after prostatectomy include:
- Sildenafil (Viagra): Often the first-line treatment.
- Tadalafil (Cialis): Longer-lasting effects.
- Vardenafil (Levitra): Similar to sildenafil.
- Sildenafil (Viagra): Often the first-line treatment.
- Tadalafil (Cialis): Longer-lasting effects.
- Vardenafil (Levitra): Similar to sildenafil.
The number of pads needed after prostatectomy varies, but most men use several pads per day initially. Over 3-6 months, as urinary control improves, the number of pads typically decreases and can also stop. With better techniques like retzius sparing robotic prostatectomy and bladder neck preservation, patients can achieve >95% immediate continence, thereby decreasing the need for pads.
The success rate of robotic prostatectomy is high for localized prostate cancer, with cancer control rates similar to those of traditional open surgery. Five-year cancer-specific survival rates are close to 100% for localized cases.
Urinary incontinence after robotic prostatectomy can last from a few weeks to several months. Most men see significant improvement within six to twelve months. With advanced techniques like robotic prostatectomy, many patients regain early continence, thereby making it the preferred choise for patients undergoing surgery for prostate cancer.
A robotic prostatectomy typically takes two to four hours, depending on the complexity of the case and the urologists experience.
After prostatectomy, PSA levels should be undetectable or very close to zero after 3 months. Any detectable PSA may indicate residual or recurrent cancer.
The number of lymph nodes removed during radical prostatectomy varies, typically ranging from 10 to 20, depending on the extent of cancer and the urologist surgeon's approach.
Light exercise, such as walking, can be resumed within 2-3 days after robotic surgery. More strenuous activities should be avoided for six weeks or until cleared by your urologist.
Recovery time for robotic prostatectomy varies, but most men return to normal activities within two weeks. Full recovery may take up to six weeks.
Hormone therapy is effective in slowing the progression of prostate cancer and reducing symptoms, especially in advanced cases. However, it is not a cure and is usually part of a broader treatment plan.
