[Local recurrence after radical prostatectomy for prostatic cancer]

Area of Science:

• Urologic Oncology
• Surgical Oncology
• Radiation Oncology

Context:

• Radical prostatectomy for prostate cancer has a significant local recurrence rate, ranging from 20% to 40%.
• Distinguishing between biological (PSA elevation) and clinical (palpable/visualized abnormalities) recurrences is crucial for treatment decisions.
• Variability in PSA assay sensitivity and clinical underestimation of pathological stage complicate recurrence evaluation.

Purpose:

• To re-evaluate the oncological utility of radical prostatectomy as a standalone treatment for prostate cancer.
• To analyze the definitions and management strategies for local recurrence following radical prostatectomy.
• To assess the efficacy of salvage radiation therapy for local prostate cancer recurrence.

Summary:

• Local recurrence after radical prostatectomy can manifest as biological (PSA rise) or clinical (physical findings) events.
• Salvage radiation therapy is often considered for local recurrences, but its efficacy is debated, with variable success rates reported.
• PSA kinetics (rate of rise, doubling time) are valuable for monitoring recurrence, and hormone therapy should be used cautiously to preserve its diagnostic utility.

Impact:

• Highlights the need for a critical appraisal of radical prostatectomy's role in achieving a complete cure for prostate cancer.
• Emphasizes the importance of standardized PSA assays and accurate staging for reliable recurrence assessment.
• Suggests radiation therapy as a primary option for local recurrence, while cautioning against early use of hormone therapy.
