What was studied

The 2026 EAU-EANM-ESTRO-ESUR-ISUP-SIOG guidelines update covers treatment of relapsing, metastatic hormone-sensitive, and castration-resistant prostate cancer (PCa), based on a systematic literature review of evidence published between 2023 and 2025.

Key findings

Updated recommendations endorse risk-stratified salvage therapy for relapsing PCa and an expanded treatment toolkit for metastatic/castration-resistant disease — including ARPIs, PARP inhibitors and their combinations, metastasis-directed therapy, and PSMA-based therapy — each graded by strength of evidence.

Study limitations

Recommendations do not account for variations in cost, reimbursement, or resource availability across healthcare systems; the review window is limited to 2023–2025, so very recent data may be excluded.

Clinical implications

Use risk stratification to guide salvage therapy after primary PCa treatment, and consider the expanded armamentarium — ARPIs, PARP inhibitors (alone or combined), and PSMA-targeted agents — when managing metastatic or castration-resistant disease. Always weigh local formulary access and reimbursement realities, as the guidelines do not factor these in.

Caveats

  • Cost and reimbursement considerations are explicitly excluded from the recommendations, which may limit direct applicability in resource-constrained settings.
  • No specific sample size is applicable — this is a guidelines document, not a primary study. Level of evidence rated '1' reflects the guideline panel's systematic review process, not a single trial.
  • Specific strength-of-recommendation grades for individual interventions are not detailed in the abstract; the full guideline document should be consulted for granular recommendations.
