2025 ISUP Vienna Multidisciplinary Expert Consultation Conference on the Evaluation of Treatment Effects in Prostate and Bladder Cancer
On September 11, 2025, the International Society of Urological Pathology will host a “Multidisciplinary Expert Consultation Conference on the Evaluation of Treatment Effects in Prostate and Bladder Cancer“, open to members and non-member clinicians and scientists in pathology, urology, oncology, and related fields, immediately after the 37th European Congress of Pathology (ECP), in the beautiful city of Vienna, Austria. This consensus will be in person, without a hybrid format.
This conference will be hosted at the Josephinum (address: Währinger Str. 25, 1090 Wien, https://www.josephinum.ac.at). The hotel is approximately 10 km away from the Austria Center.
Meeting Objectives:
- Refine histopathologic criteria for evaluating treatment effects
- Establish Gleason grading recommendations post-treatment
- Develop standardized criteria for grading treatment effects
- Define criteria for pT0 cancer and evaluate current methods of minimal residual disease (MRD) detection
- Outline best practices for ancillary studies, including immunohistochemical staining, molecular testing, AI, and diagnostic work-up protocols
- Provide recommendations for pathology reporting
This Consensus will be Co-Chaired by ISUP members, Dr. Liang Cheng (Providence, RI, USA), and Dr. Geert van Leenders (Rotterdam, Netherlands).
