Optimal Surveillance Algorithm Following Focal Therapy of Prostate Cancer
In this 13-minute presentation, Herbert Lepor, MD, focuses on the development and implementation of an evidence-based surveillance algorithm following focal therapy for prostate cancer. Dr. Lepor highlights the fundamental role of longitudinal PSA testing, imaging, and biopsy in monitoring patients. Key findings from his cohort of over 500 patients include:
PSA Trends as Predictors: Longitudinal consecutive PSA rises are the strongest predictors of clinically significant recurrence.
MRI Utility: Positive MRIs are associated with a 30-40% likelihood of detecting cancer, but the overall frequency of positive MRIs remains low, justifying their use selectively.
Biopsy Strategies: The cohort’s data indicate that systematically performing biopsies on patients with negative MRIs yields low detection rates, and most findings represent low-volume or less concerning disease.
Dr. Lepor concludes that the current algorithm incorporates PSA testing, selective MRI, and biopsy based on imaging or PSA trends, reducing unnecessary procedures while maintaining effective cancer surveillance. However, further data, especially at the five-year mark, are needed to refine this approach further. This pragmatic and evolving strategy balances oncologic safety with patient quality of life.
