According to the National Cancer Institute (NCI) and the International Federation of Gynecology and Obstetrics (FIGO) staging system, ovarian cancer has four main stages:
Stage I: Cancer is limited to the ovaries
- IA: One ovary involved
- IB: Both ovaries involved
- IC: Cancer on ovary surface or capsule rupture
Stage II: Cancer has spread within the pelvis
- IIA: Spread to uterus/fallopian tubes
- IIB: Spread to other pelvic organs
Stage III: Cancer has spread to the abdomen
- IIIA: Microscopic spread
- IIIB: Visible tumors ≤ 2cm
- IIIC: Visible tumors > 2cm
Stage IV: Cancer has spread beyond the abdomen to distant organs
Regarding outcomes, according to the American Cancer Society's most recent statistics:
5-year survival rates:
- Stage I: 90%
- Stage II: 70%
- Stage III: 39%
- Stage IV: 17%
However, the National Comprehensive Cancer Network (NCCN) Guidelines emphasize that these statistics:
- Are based on past data and may not reflect newest treatments
- Are general averages and individual outcomes can vary significantly
- Don't account for personal factors like age, overall health, and specific tumor characteristics
The Society of Gynecologic Oncology (SGO) stresses that early detection significantly improves outcomes, which is why recognizing symptoms and getting prompt medical attention is crucial.
Always discuss your specific situation with your healthcare team, as they can provide the most accurate assessment based on your individual case.
