Zusammenfassung

Bedingt durch Chemotherapieresistenz und das Fehlen einer Methode zur Früherkennung besitzt das Ovarialkarzinom die ungünstigste Prognose unter den gynäkologischen Malignomen. In den letzten Jahren haben morphologische, genetische und epigenetische Studien sowie Expressionsanalysen unter Zuhilfenahme sog. Hochdurchsatzverfahren zu der Erkenntnis geführt, dass sich unter dem Begriff Ovarialkarzinom eine heterogene Gruppe von Tumoren verbirgt, die unterschiedliche Charakteristika, unterschiedliche Phänotypen und auch unterschiedliche Prognosen aufweisen. Inzwischen unterscheidet man grundsätzlich 2 Typen des Ovarialkarzinoms: Das Typ-I-Karzinom ist hochdifferenziert und entwickelt sich aus benignen Vorläuferläsionen, wohingegen das Typ-II-Karzinom schlecht differenziert ist und sich in der Regel rasch sowie ohne eine klinisch nachweisbare Vorläuferläsion entwickelt.

Abstract

Ovarian cancer carries the worst prognosis among all forms of gynecological cancer mainly due to chemoresistance and the lack of an effective screening method for the detection of early stage disease. Recent morphological, genetic and epigenetic studies as well as expression analyses utilizing high-throughput methods have led to the conclusion that ovarian cancer covers a heterogeneous group of tumors with different characteristics, phenotypes and outcome. In general there are two types of ovarian cancer: type I tumors are well differentiated (low-grade) and progress from benign lesions via borderline tumors, whereas the poorly differentiated (high-grade) type II carcinomas arise de novo or in flat precursor lesions.
