The standardized collation of the quality of treatment is a subject of discussion both nationally and internationally. This article presents the work of the International Consortium for Health Outcomes Measurement (ICHOM) and the validated German translation of the expanded prostate cancer index composite (EPIC-26). This questionnaire allows a standardized interdisciplinary collation of the quality of treatment for all therapy modalities of localized prostate cancer. Use of the ICHOM standard set and the EPIC-26 achieves a possibility for comparison of each form of therapy with respect to the curative success and the effect on health and quality of life of patients.
