Notes

C481 Specified parts of peritoneum (including omentum and mesentery) C482 Peritoneum, NOS C488 Overlapping lesion of retroperitoneum and peritoneum **Note 1:** This schema is based on the UICC chapter *Ovary,* pages 222-22. * Primary sites C481, C482 and C488 are not listed in this chapter of the UICC manual; however, they are included in this schema and TNM staged if appropriate histology criteria are met **Note 2:** 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 3:** The FIGO stages are based on surgical staging. (TNM stages are based on clinical and/or pathologic classification). **Note 4:** In addition to directly assigning TNM, Summary Stage 2000 (SS2000) must be captured. If directly assigning SS2000, use the *Retroperitoneum & Peritoneum* chapter on page 188 of the [SS2000 on-line manual](http://seer.cancer.gov/tools/ssm/SSSM2000-122012.pdf#page=188).
