Definition / general
  • Widespread intra-abdominal disease is common, so multiple biopsies of commonly involved sites are required for staging
Primary tumor (T) and FIGO stage
  • TX: primary tumor cannot be assessed
  • T0: no evidence of primary tumor
  • Tis: carcinoma in situ (limited to tubal mucosa)

  • T1 (I): tumor limited to fallopian tube(s)
  • T1a (IA): tumor limited to one tube, without penetrating the serosal surface; no ascites
  • T1b (IB): tumor limited to both tubes, without penetrating the serosal surface; no ascites
  • T1c (IC): tumor limited to one or both tubes, with extension onto or through the tubal serosa or with malignant cells in ascites or peritoneal washings

  • T2 (II): tumor involves one or both fallopian tubes with pelvic extension
  • T2a (IIA): extension or metastasis to the uterus or ovaries
  • T2b (IIB): extension to other pelvic structures
  • T2c (IIC): pelvic extension with malignant cells in ascites or peritoneal washings

  • T3 (III): tumor involves one or both fallopian tubes, with peritoneal implants outside the pelvis
  • T3a (IIIA): microscopic peritoneal metastasis outside the pelvis
  • T3b (IIIB): macroscopic peritoneal metastasis outside the pelvis 2 cm or less in greatest dimension
  • T3c (IIIC): peritoneal metastasis outside the pelvis and more than 2 cm in diameter

  • Notes:
    • Liver capsule metastasis is T3 / Stage III
    • Liver parenchymal metastasis is M1 / Stage IV
    • Pleural effusion must have positive cytology for M1 / Stage IV
Regional lymph nodes (N) and FIGO stage
  • NX: regional lymph nodes cannot be assessed
  • N0: no regional lymph node metastasis
  • N1 (IIIC): regional lymph node metastasis
Distant Metastasis (M) and FIGO stage
  • M0: no distant metastasis
  • M1 (IV): distant metastasis (excludes metastasis within the peritoneal cavity)
Stage grouping
Stage 0: T1s N0 M0
Stage I: T1 N0 M0
Stage IA: T1a N0 M0
Stage IB: T1b N0 M0
Stage IC: T1c N0 M0
Stage II: T2 N0 MO
Stage IIA: T2a N0 M0
Stage IIB: T2b N0 M0
Stage IIC: T2c N0 M0
Stage III: T3 N0 M0
Stage IIIA: T3a N0 M0
Stage IIIB: T3b N0 M0
Stage IIIC: T3c N0 M0 or any T N1 M0
Stage IV: M1

  • Notes:
    • FIGO no longer includes Stage 0 (Tis)
