Beyond One-Size-Fits-All Active Surveillance for Low-Risk Prostate Cancer: Risk-Adapted Follow-Up, De-Escalation Pathways, and Focal Therapy as Tailored Strategy

Le résumé fourni par la source

Low-risk prostate cancer (PCa) has historically been overtreated, exposing men to unnecessary morbidity. Emerging evidence supports conservative management of low-risk PCa without immediate radical intervention. Contemporary data show a marked decline in surgical overtreatment, with the proportion of radical prostatectomies yielding only Grade Group 1 cancers falling from 32.4% in 2010 to 7.8% in 2020 in the US SEER registry. Long-term studies confirm that deferring treatment is safe for low-risk disease, with PCa-specific survival exceeding 95% at 15-25 years for cohorts managed with surveillance. Major guidelines now endorse active surveillance (AS) as the preferred management for low-risk PCa. An alternative risk stratification system that expands the low-risk category was shown to reclassify 45-83% more men as low risk without increasing 15-year PCa mortality. Focal therapy has emerged as a potential middle-ground strategy, though evidence is still limited. The paradigm for managing low-risk PCa has shifted toward conservatism, with AS firmly established as the standard of care. Continued efforts to refine risk stratification and evaluate focal therapy are needed to further optimize individualized care, minimize harm, and maintain excellent cancer-specific outcomes for low-risk PCa. This comprehensive review aims to create a practical, risk-adapted framework for managing patients on AS. We will: (i) summarize inclusion criteria and outcomes, (i) compare AS follow-up schedules across major institutions and guidelines, (iii) provide evidence-based criteria to de-intensify surveillance in men with sustained stability and (iv) clarify the role of focal therapy as an intermediate treatment option within the AS continuum.
