title: [New FIGO classification of ovarian, fallopian tube and primary peritoneal cancer].
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).
