Carcinoma and Carcinosarcoma of Corpus Uteri; Uterus, NOS (excluding Placenta and Adenosarcoma, Leiomyosarcoma, and Endometrial Stromal Sarcoma (ESS))

Primary Site Histology Staging Type
C540-C543, C548-C549, C559 8000-8790, 8950-8951, 8980-8981 TNM 7 and Summary Stage
C540-C543, C548-C549, C559 9700-9701 Summary Stage only

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

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-Endometrium, pages 212-216.

  • Primary sites C542, C548, and C549 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: 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: Carcinosarcoma should be staged as carcinoma.

Note 5: This schema is for carcinoma and carcinosarcoma. When coding pay attention to the FIGO Editions and descriptions about cell and tumor types, disease extension, lymph node status and metastasis.

Note 6: 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 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.
