Zusammenfassung

Die systemische Aussaat einzelner maligner Zellen aus dem Tumorzellverband stellt einen frühen essentiellen Schritt bei der Metastasierung solider Tumoren dar. Für das Mammakarzinom und andere solide Tumoren konnte gezeigt werden, dass zirkulierende Tumorzellen (CTC) im Blut prognostisch ungünstig sind. In diesem Artikel werden die essentiellen Schritte der Tumorzelldissemination erläutert und die Grundlagen der Tumorzelldetektion dargestellt. Der aktuelle Stand der Wissenschaft bei der Detektion zirkulierender Tumorzellen beim Mamma- und Blasenkarzinom wird erörtert und die potenzielle klinische Bedeutung des Nachweises von CTC beim Blasenkarzinom diskutiert. 

Abstract

Systemic dissemination of single malignant cells from a tumour cell cluster represents an early essential step in the metastastic cascade of solid tumours. Studies in breast cancer and other solid malignancies have shown that the presence of circulating tumour cells (CTC) in the blood is associated with an unfavourable prognosis. In this article the key steps in the course of tumour cell dissemination and the basics of single cell detection are explained. The current literature about single cell detection in carcinoma of the breast and urothelial cancer is reviewed and the potential clinical implications of CTC-detection in bladder cancer are discussed.
