Ovarian Cancer Staging

Staging (note stage is same as T value in TNM):

• I – limited to ovaries
• Ia – one ovary, intact capsule, no surface involvement, peritoneal washings negative
• Ib – both ovaries, intact capsule, no surface involvement, peritoneal washings negative
• Ic – one or both ovaries, with one or more of: ruptured capsule, surface involvement, positive peritoneal washings
• II – pelvic extension or implants
• IIa – uterus or fallopian tube, peritoneal washings negative
• IIb – other pelvic tissues, peritoneal washings negative
• IIc – pelvic extension with positive peritoneal washings
• III – outside the pelvis
• IIIa – microscopic disease only
• IIIb – macroscopic disease, <= 2cm
• IIIc – >2cm or regional nodes positive
• IV – extraperitoneal metastasis (does not include liver capsule)

Other important prognostic information:

• Lymphovascular invasion (look just under surface of ovary)
