Notes

C540 Isthmus uteri C541 Endometrium C542 Myometrium C543 Fundus uteri C548 Overlapping lesion of corpus uteri C549 Corpus uteri C559 Uterus, NOS **Note 1:** This schema is based on the UICC chapter *Uterus-Uterine Sarcomas* pages 217-221. * Primary sites C541, C542, C548, and C549 are listed in the chapter heading but are not specified in the anatomic subsites in this chapter of the UICC manual; however, they are included in this schema and TNM staged if appropriate histology criteria are met * Primary site group C53 is listed; however, is not included in this schema. See the *Cervix* schema **Note 2:** The TNM 7th Edition staging reflects the new staging adopted by the International Federation of Gynecology and Obstetrics (FIGO) and utilizes three new staging schemas for cancer of the Corpus Uteri based on histology. The three new schemas are 1. Carcinoma and carcinosarcoma 2. Leiomyosarcoma and endometrial stromal sarcoma (ESS) 3. Adenosarcoma **Note 3:** The FIGO stages are based on surgical staging. (TNM stages are based on clinical and/or pathologic classification). **Note 4:** This schema is for adenosarcoma ONLY. When coding pay attention to the FIGO Editions and descriptions about cell and tumor types, disease extension, lymph node status and metastasis. **Note 5:** TNM values correspond to the stages accepted by FIGO. Note that FIGO uses a single stage value which corresponds to different groupings of T, N, and M values. **Note 6:** UICC 7th edition includes sarcomas of the cervix uteri with Uterine sarcomas and AJCC 7th edition limits it to sarcoma of the corpus uteri. SEER is not currently collecting TNM information on cervical sarcomas. **Note 7:** In addition to directly assigning TNM, Summary Stage 2000 (SS2000) must be captured. If directly assigning SS2000, use the *Corpus Uteri, Uterus, NOS* chapter on page 208 of the [SS2000 on-line manual](https://seer.cancer.gov/tools/ssm/ssm2000/SSSM2000-122012.pdf#page=208).
