1. INTRODUCTION
1.1. Aim and objectives
The aim of these Guidelines is to present the current evidence for the diagnosis and treatment of patients with cancer of the testis. Testicular cancer (TC) represents 5% of urological tumours affecting mostly younger males. This document addresses post-pubertal testicular germ-cell tumours (TGCTs) in the male, including spermatocytic tumour and sex cord-stromal tumours.
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 references/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 European Association of Urology (EAU) Guidelines Panel on TC consists of a multidisciplinary group of clinicians, including urologists, medical oncologists, a radiation-oncologist, patient representatives and two pathologists. When necessary, consultants from other specialties provide input. Members of this Panel have been selected based on their expertise to represent the professionals that treat patients with TC. All experts involved in the production of this document have submitted potential conflict of interest statements which can be viewed on the EAU website: http://www.uroweb.org/guideline/testicular-cancer/.
1.3. Available publications
A quick reference document (Pocket Guidelines) is available in print and on the EAU website. The Pocket Guidelines is an abridged version of the Guidelines which may require consultation together with the full text version. Several scientific publications are available, as are a number of translations of all versions of the EAU TC Guidelines. All documents are accessible through the EAU website: http://www.uroweb.org/guideline/testicular-cancer/.
An EAU Guidelines App is also available for iOS and Android devices containing the Pocket Guidelines, interactive algorithms and calculators, clinical decision support tools, guidelines cheat sheets and links to the extended guidelines.
1.4. Publication history and summary of changes
1.4.1. Publication history
The EAU published the first guidelines on TC in 2001. Since 2008, the TC Guidelines contains a separate chapter on testicular stromal tumours. The 2026 TC guideline presents a limited update of the 2024 publication. A summary paper of the EAU TC guideline has been published in the society’s scientific journal European Urology in 2023 [1].
1.4.2. Summary of changes
For the 2026 TC Guidelines new and relevant evidence was identified, collated and appraised through a structured assessment of the literature for all sections of the Guidelines. Key changes include:
- New recommendation in Chapter 5 regarding testicular prosthesis.
- Substantial text additions and restructure to Chapter 6, including a new section on the treatment of bone metastases - Section 6.3.7.
- Restructure of management of seminoma clinical stage IIA/B including nsRPLND and radio-
chemotherapy - Section 6.2.2 - Updated summary of evidence and new recommendation in Section 6.2.2.b.1.b on de-escalating approaches.
- Expansion and restructure to Chapter 8.
