Guidelines

Prostate Cancer

1. INTRODUCTION

1.1. Aims and scope

The Prostate Cancer (PCa) Guidelines Panel have prepared this guidelines document to assist medical professionals in the evidence-based management of PCa.

It must be emphasised that clinical guidelines present the best evidence available to the experts but following guideline recommendations will not necessarily result in the best outcome. Guidelines can never replace clinical expertise when making treatment decisions for individual patients, but rather help to focus decisions - also taking personal values and preferences/individual circumstances of patients into account. Guidelines are not mandates and do not purport to be a legal standard of care.

1.2. Panel composition

The PCa Guidelines Panel consists of an international multidisciplinary group of urologists, radiation oncologists, medical oncologists, radiologists, pathologists, a geriatrician and a patient representative.

All imaging sections in the text have been developed jointly with the European Society of Urogenital Radiology (ESUR) and the European Association of Nuclear Medicine (EANM). Representatives of the ESUR and the EANM in the PCa Guidelines Panel are (in alphabetical order): Dr. A. Farolfi, Dr. D. Oprea-Lager, Prof.Dr. O. Rouvière and Dr. I.G. Schoots.

All radiotherapy (RT) sections have been developed jointly with the European Society for Radiotherapy & Oncology (ESTRO). Representatives of ESTRO in the PCa Guidelines Panel are (in alphabetical order): Prof.Dr. G. De Meerleer, Prof.Dr. A.M. Henry, Prof.Dr. M.D. Mason and Prof.Dr. T. Wiegel.

The International Society of Urological Pathology is represented by Prof.Dr. T. van der Kwast and Prof.Dr. A. van Leenders.

Dr. S. O’Hanlon, consultant geriatrician, representing the International Society of Geriatric Oncology (SOIG) contributed to the sections addressing life expectancy, health status and quality of life (QoL) in particular.

Dr. E. Briers, expert Patient Advocate Hasselt-Belgium representing the patient voice as delegated by the European Prostate Cancer Coalition/Europa UOMO.

All experts involved in the production of this document have submitted potential conflict of interest statements which can be viewed on the EAU website Uroweb: https://uroweb.org/guideline/prostate-cancer/.

1.3. Available publications

A quick reference document (Pocket guidelines) is available. This is an abridged version which may require consultation together with the full text version. Several scientific publications are available [1,2] as are a number of translations of all versions of the PCa Guidelines. All documents can be accessed on the EAU website: http://uroweb.org/guideline/prostate-cancer/.

1.4. Publication history and summary of changes

1.4.1. Publication history

The EAU PCa Guidelines were first published in 2001. This 2023 document presents a limited update of the 2022 EAU-EANM-ESTRO-ESUR-ISUP-SIOG PCa Guidelines.

1.4.2. Summary of changes

The literature for the complete document has been assessed and updated based upon a review of all recommendations and creation of appropriate GRADE forms. Evidence summaries and recommendations have been amended throughout the current document and several new sections have been added.

All chapters of the 2022 PCa Guidelines have been updated. New data have been included in the following sections, resulting in new sections, and new and revised recommendations:

Weak

5.2.8.2 Summary of evidence and recommendations for performing prostate biopsy (in line with the EAU Urological Infections Guidelines Panel)

Summary of evidence

LE

A meta-analysis of eight studies including 1,596 patients showed significantly reduced infectious complications in patients undergoing transperineal biopsy as compared to transrectal biopsy.

1a

A meta-analysis of eight non-RCTS reported comparable rates of post-biopsy infections in patients undergoing transperineal biopsy irrespective if antibiotic prophylaxis was given or not.

1a

A meta-analysis of eleven RCTs including 2,036 men showed that use of a rectal povidone-iodine preparation before transrectal biopsy, in addition to antimicrobial prophylaxis, resulted in a significantly lower rate of infectious complications.

Weak

Base change in treatment on biopsy progression, not on progression on MRI and/or PSA.

Weak

#Note: Please be aware that the various options in the following flowcharts present a generalised approach
only, and cannot take the management of individual patients into account, nor the availability of resources.

7.1.5 Summary of evidence for follow-up after treatment with curative intent

Summary of evidence

LE

A detectable PSA, indicating a relapse of the disease, must be differentiated from a clinically meaningful relapse. The PSA threshold that best predicts further metastases after RP is > 0.4 ng/mL and > NADIR + 2 ng/mL after IMRT/VMAT plus IGRT (± ADT].
