C480-C482, C488 | 8935-8936 | TNM 7 and Summary Stage |
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
C480 Retroperitioneum 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 *Gastrointestinal Stromal Tumour (GIST),* pages 78-81. * Primary sites C480, C482, and C488 are not listed in this chapter of the UICC manual; however, they are included in this schema in and TNM staged **Note 2:** 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](https://seer.cancer.gov/tools/ssm/ssm2000/SSSM2000-122012.pdf#page=188).Main Data Items
