Zusammenfassung

Der häufigste maligne Tumor des harnableitenden Systems ist das Urothelkarzinom (UC). Mit der Einführung neuartiger immunologischer Therapieoptionen im metastasierten als auch im lokal begrenzten Setting ist die Erforschung immunologischer Biomarker zur Prädiktion eines möglichen Therapieerfolgs in den Fokus der klinisch-translationalen Forschung gerückt. Beispielsweise können die Expressionswerte des programmierten Zelltodliganden 1 (PD-L1) in UC-Tumoren den Ärzten bei der Entscheidung helfen, welche Patienten mit größerer Wahrscheinlichkeit auf immunonkologische Therapien ansprechen; vor dem Hintergrund neuer Zulassungen mit vorgeschriebener PD-L1-Testung (z. B. adjuvante Nivolumab-Therapie nach radikaler Zystektomie) wird die Harmonisierung der PD-L1-Testung immer wichtiger. Neben der PD-L1-Bestimmung wurden und werden allerdings auch umfassendere potenziell prädiktive Biomarker wie „tumor mutational burden“ (Tumormutationslast) und Immunsignaturen/-phänotypen in klinischen Studien untersucht. Die vorliegende Arbeit gibt einen gestrafften Überblick über bereits bestehende Erkenntnisse und neue Entwicklungen auf dem Gebiet des UC.
