FIGO staging of ovarian cancer 2014 [11]

Stage I: Tumour confined to ovaries 1A: Tumor limited to 1 ovary, capsule intact, no tumor on surface, negative washings.
1B: Tumor involves both ovaries otherwise like IA.
1C: Tumor limited to 1 or both ovaries
IC1: Surgical spill
IC2: Capsule rupture before surgery or tumor on ovarian surface.
IC3: Malignant cells in the ascites or peritoneal washings.
Stage II: Tumor involves 1 or both ovaries with pelvic extension (below the pelvic brim) or primary peritoneal cancer 11A: Extension and/or implant on uterus and/or Fallopian tubes
IIB: Extension to other pelvic intraperitoneal tissues
Stage III: Tumor involves 1 or both ovaries with cytologically or histologically confirmed spread to the peritoneum outside the pelvis and/or metastasis to the retroperitoneal lymph nodes IIIA: Positive retroperitoneal lymph nodes and /or microscopic metastasis beyond the pelvis
IIIA1: Positive retroperitoneal lymph nodes only
IIIA1(i) Metastasis ≤ 10 mm
IIIA1(ii) Metastasis > 10 mm
IIIA2: Microscopic, extrapelvic (above the brim) peritoneal involvement ± positive retroperitoneal lymph nodes
IIIB: Macroscopic, extrapelvic, peritoneal metastasis ≤ 2 cm ± positive retroperitoneal lymph nodes. Includes extension to capsule of liver/spleen.
IIIC: Macroscopic, extrapelvic, peritoneal metastasis > 2 cm ± positive retroperitoneal lymph nodes. Includes extension to capsule of liver/spleen.
Stage IV: Distant metastasis excluding peritoneal metastasis IVA: Pleural effusion with positive cytology
IVB: Hepatic and/or splenic parenchymal metastasis, metastasis to extra- abdominal organs (including inguinal lymph nodes and lymph nodes outside of the abdominal cavity)
