If you are working with a site/histology that only summary stages and you need to directly code it, please use the SEER Summary Stage 2000 manual

Notes

C569 Ovary **Note 1:** This schema is based on the UICC chapter *Ovary,* pages 222-226. **Note 2:** Laterality must be coded for this site. **Note 3:** TNM values correspond to the stages accepted by the Federation Internationale de Gynecologic et d'Obstetrique (FIGO). * Note that FIGO uses a single stage value which corresponds to different groupings of T, N, and M values **Note 4:** The FIGO stages are based on surgical staging. (TNM stages are based on clinical and/or pathologic classification). **Note 5:** In addition to directly assigning TNM, Summary Stage 2000 (SS2000) must be captured. If directly assigning SS2000, use the *Ovary* chapter on page 212 of the [SS2000 on-line manual](https://seer.cancer.gov/tools/ssm/ssm2000/SSSM2000-122012.pdf#page=212).
