What are the indications and management strategies for radical prostatectomy in patients with localized prostate cancer?

Radical Prostatectomy for Localized Prostate Cancer: Indications and Management

Radical prostatectomy should be offered as a primary treatment option for patients with localized prostate cancer who are younger or healthier (less than 65 years of age or with greater than 10-year life expectancy), as they are more likely to experience cancer control benefits from this procedure. 1

Indications for Radical Prostatectomy

Patient Selection Based on Disease Stage

• Low-risk localized prostate cancer: Radical prostatectomy is an effective treatment option 1

  • However, active surveillance should be discussed as an alternative option for these patients 1

• Intermediate-risk localized prostate cancer: Radical prostatectomy should be discussed with these patients if they have a minimal life expectancy of 10 years 1

  • Provides excellent cancer control with 10-year recurrence-free survival rates of approximately 80% in organ-confined disease 2

• High-risk localized prostate cancer: Radical prostatectomy should be discussed with these patients if they have a minimal life expectancy of 5 years 1

• Locally advanced (T3-T4) prostate cancer: May be considered but should only be performed after careful staging and multidisciplinary team discussion 1

  • 10-year recurrence-free survival drops to approximately 30% in non-organ-confined cancers 2

Patient Selection Based on Age and Health Status

• Assessment of patient's life expectancy, overall health status, and tumor characteristics is necessary before making treatment decisions 1
• Younger patients (<65 years) derive greater cancer control benefits from prostatectomy 1
• Older men experience higher rates of permanent erectile dysfunction and urinary incontinence after prostatectomy compared to younger men 1

Surgical Approaches and Techniques

Surgical Approaches

• Options include:

  • Open radical retropubic prostatectomy
  • Laparoscopic radical prostatectomy
  • Robot-assisted radical prostatectomy
  • Perineal approach

• Blood loss considerations: Robotic/laparoscopic or perineal techniques are associated with less blood loss than retropubic prostatectomy 1

  • These minimally invasive approaches may reduce the need for blood transfusions (68 fewer transfusions per 1000 men compared to open surgery) 3

Nerve-Sparing Technique

• Nerve-sparing technique is associated with better erectile function recovery than non-nerve-sparing approaches 1
• Should be considered in appropriate candidates to preserve sexual function

Pelvic Lymph Node Dissection (PLND)

• PLND can be considered for any localized prostate cancer patients undergoing radical prostatectomy 1
• PLND is recommended for patients with unfavorable intermediate-risk or high-risk disease 1
• Patients should be counseled about potential complications, including lymphocele development 1

Perioperative Management

Preoperative Considerations

• Neoadjuvant androgen deprivation therapy (ADT) is not recommended for patients undergoing radical prostatectomy outside of clinical trials 1
• Patients should be informed about potential complications and functional outcomes

Postoperative Management

• Hospital stay is typically shorter with minimally invasive approaches compared to open surgery (1.72 days shorter on average) 3
• Postoperative pain may be less with minimally invasive approaches in the first week after surgery 3

Follow-up and Additional Treatments

Adjuvant Therapy Considerations

• Patients with unfavorable intermediate-risk or high-risk prostate cancer should be informed about benefits and risks of adjuvant radiotherapy when locally extensive disease is found at prostatectomy 1
• Approximately 35% of patients require additional cancer treatment within 5 years after radical prostatectomy 4
  • Even with pathologically organ-confined disease, about 24% require additional treatment within 5 years 4

Monitoring for Recurrence

• PSA monitoring is essential for detecting biochemical recurrence
• Complete remission after radical prostatectomy is defined as an undetectable PSA concentration (under 0.1 ng/ml) for at least 7 years 1
• Progression after radical prostatectomy is defined as an increase in PSA concentration measured on three successive occasions at monthly intervals 1

Complications and Functional Outcomes

Common Complications

• Erectile dysfunction (higher risk in older patients)
• Urinary incontinence (higher risk in older patients)
• Rectal injury (0.6% in contemporary series)
• Deep venous thrombosis (1.1%)
• Pulmonary embolism (0.7%)
• Total urinary incontinence requiring 3 or more pads per day (0.8%) 5

Long-term Outcomes

• 15-year cause-specific survival rates range from 71% to 93% depending on Gleason score 5
• 15-year metastasis-free survival rate of approximately 76% 5
• 15-year local recurrence-free survival rate of approximately 75% 5

Special Considerations

Surgeon Experience and Volume

• Surgical outcomes are better when performed in high-volume centers, especially for technically challenging cases like locally advanced disease 6

Patient Preference

• Patient preference should be considered in determining treatment, after discussion of benefits and harms of different interventions 1
• Patients should be informed about all commonly accepted initial interventions, including radical prostatectomy, radiation therapy, and surveillance 1

Radical prostatectomy remains a cornerstone treatment for localized prostate cancer with excellent long-term cancer control rates, particularly for younger patients with at least 10 years of life expectancy.
