Collaborative Stage

Note 1: The definition of TNM in AJCC 7th Edition for tumors in corpus uteri has changed from the 6th Edition and reflects the new staging adopted by the International Federation of Gynecology and Obstetrics (FIGO). There are three schemas of FIGO Stage for cancer of corpus uteri:
    a.    Carcinoma of the endometrium and carcinosarcomas
    b.    Leiomyosarcomas and endometrial stromal sarcomas (ESS)
    c.    Adenosarcomas

Starting from AJCC 7th Edition and the new FIGO Edition, the above three diseases are staged separately. The table below is for carcinoma of the endometrium and carcinosarcomas only. Alternative names of carcinoma of the endometrium include uterine cancer, endometrial cancer and carcinoma of corpus uteri. When coding, pay attention to the FIGO Editions and descriptions about cell and tumor types, disease extension, lymph node status and metastasis.
Note 2: FIGO stage is surgical, not clinical, staging.
Note 3: When both FIGO Staging and extension detail are available, record the code with extension detail over the FIGO Staging. For example, in a report stating "tumor is confined to endometrium (code 100) " and FIGO Stage IA (code 125), use code 100.
Note 4: The AJCC 6th and 7th Editions are different for staging of this disease.
Note 5: Endocervical glandular involvement only should be staged as T1NOS.
Note 6: By AJCC 7th and the new FIGO Editions, positive cytology has to be reported separately (see Site Specific Factor 2), without changing stage. Since "cancer cells in ascites or in peritoneal washings" was not specifically categorized in the 1977 Summary Stage Guide, it is unclear to which stage previous cases may have been coded.
Note 7: According to the AJCC, extension to the bowel or bladder mucosa must be proven by biopsy in order to rule out bullous edema.
Note 8: Simultaneous tumors of the uterine corpus and ovary/pelvis in association with ovarian/pelvic endometriosis should be classified as independent primary tumors.

* For CS Extension codes 100-400 ONLY. The SS77 and SS2000 category are assigned based on the value of CS Extension and peritoneal cytology status as coded in Site Specific Factor 2. See the extra table, CS Tumor Extension Cytology Table.
