Gastrointestinal Stromal Tumor of Rectum and Rectosigmoid Junction
Primary Site | Histology | Staging Type |
---|---|---|
C199, C209 | 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
C199 Rectosigmoid junction
C209 Rectum, NOS
Note 1: This schema is based on the UICC chapter Gastrointestinal Stromal Tumour (GIST), pages 78-81.
- Primary site C199 is not listed in this chapter of the UICC manual; however, it is included in this schema and TNM staged
Note 2: In addition to directly assigning TNM, Summary Stage 2000 (SS2000) must be captured. If directly assigning SS2000, use the Rectum chapter on page 100 of the SS2000 on-line manual.
