Zusammenfassung

Aufgrund neuer Erkenntnisse bzgl. Pathogenese und Ergebnissen klinischer Studien zur Prognose des Ovarial-, Tuben- und primären Peritonealkarzinoms hat die FIGO eine neue Klassifikation erarbeitet. Diese ist seit dem 01.01.2014 zur Stadieneinteilung des Ovarial-, Tuben- und primären Peritonealkarzinoms sowie der malignen ovariellen Keimzell- und der potenziell malignen Keimstrangstromatumoren gültig. Wesentliche Änderungen betreffen die Subkategorisierung des Stadiums FIGO IC/T1c, die Unterteilung der regionären Lymphknotenmetastasen anhand ihrer Größe (≤/> 10 mm) sowie der Fernmetastasen. Letztere werden in ein Stadium IVA und IVB unterteilt.

Abstract

During recent years paramount changes have occurred in the pathogenesis of ovarian cancer and recent clinical studies identified new prognostic factors. Consequently, the FIGO has established a new staging system collectively covering carcinomas derived from the ovaries, the fallopian tubes and primary peritoneal cancers as well as malignant ovarian germ cell and sex-cord stromal tumors. The new staging system started on 01 January 2014. Major changes occurred in the FIGO IC/T1c stage with surgical spill (FIGO IC1/T1c1) versus capsule ruptured before surgery or tumor on ovarian or fallopian tube surface (FIGO IC2/T1c2) versus malignant cells in the ascites or peritoneal washings (FIGO IC3/T1c3). The regional lymph node metastases were subcategorised using a cut-off value of 10 mm as the largest dimension of the metastatic deposits. Distant metastases (excluding peritoneal metastases) were substaged as FIGO IVA/M1a in cases of cytologically or histologically proven pleural involvement and as FIGO IVB/M1b in cases of parenchymal metastases and metastases in extra-abdominal organs (including lymph nodes outside the peritoneal cavity and the inguinal lymph nodes).
