Ovarian cancer staging is by the FIGO staging system and uses information obtained after surgery, which can include a total abdominal hysterectomy, removal of (usually) both ovaries and fallopian tubes, (usually) the omentum, and pelvic (peritoneal) washings for cytology. The AJCC stage is the same as the FIGO stage.
* Stage I - limited to one or both ovaries
o IA - involves one ovary; capsule intact; no tumor on ovarian surface; no malignant cells in ascites or peritoneal washings
o IB - involves both ovaries; capsule intact; no tumor on ovarian surface; negative washings
o IC - tumor limited to ovaries with any of the following: capsule ruptured, tumor on ovarian surface, positive washings
* Stage II - pelvic extension or implants
o IIA - extension or implants onto uterus or fallopian tube; negative washings
o IIB - extension or implants onto other pelvic structures; negative washings
o IIC - pelvic extension or implants with positive peritoneal washings
* Stage III - microscopic peritoneal implants outside of the pelvis; or limited to the pelvis with extension to the small bowel or omentum
o IIIA - microscopic peritoneal metastases beyond pelvis
o IIIB - macroscopic peritoneal metastases beyond pelvis less than 2 cm in size
o IIIC - peritoneal metastases beyond pelvis > 2 cm or lymph node metastases
* Stage IV - distant metastases--in the liver, or outside the peritoneal cavity
Para-aortic lymph node metastases are considered regional lymph nodes (Stage IIIC).
