SITE SPECIFIC DATA ITEMS (SSDI)/ GRADE

Description

Federation Internationale de Gynecologie et d'Obstetrique (FIGO) is a staging system for female reproductive cancers. FIGO is a worldwide organization of obstetricians and gynecologists who maintain the international staging systems for female genital organs. The FIGO staging system has been adapted into the AJCC staging manual. FIGO uses Roman numerals and subscripts to define a stage. There is no T, N, or M descriptor with FIGO stage, only a stage group. For example, FIGO Stage IA is equivalent to T1a, FIGO Stage III can be either T3_ or N1, and FIGO Stage IV is M1. FIGO stages vary by primary site, but the structure is similar throughout. FIGO no longer includes an in-situ stage (Tis, Stage 0). For in situ tumors, code the following * Code 97: Not applicable: Carcinoma in situ (intraepithelial, noninvasive, preinvasive) Note: Do not confuse FIGO stage with FIGO grade

Notes

**Note 1:** **Physician Statement** * There must be a statement about FIGO stage from the managing physician in order to code this data item. * Do not code FIGO stage based on the pathology report * Do not code FIGO stage based only on T, N, M * If "FIGO" is not included with a stated stage, then do not assume it is a FIGO stage **Note 2:** **FIGO Stage vs FIGO Grade** * FIGO stage is not the same thing as FIGO grade. Only code FIGO stage in this field, do not code FIGO grade. * Code FIGO grade in the grade fields **Note 3:** **Multiple FIGO stages** * If there is more than one FIGO stage provided from the clinical and pathological work up, code the most extensive FIGO stage. **Note 4:** **EIC, SEIC, EIN** * For Endometrial intraepithelial carcinoma **(EIC)** (8380/2) and Serous endometrial intraepithelial carcinoma **(SEIC)** (8441/2), assign the FIGO staged based on the managing physician's documentation of FIGO. (See Note 1). * If FIGO stage for EIC or SEIC is not documented by the managing physician, code unknown (code 99) * Do not code 97 (in situ) for EIC or SEIC since FIGO does not have a Stage 0 * If diagnosis is Endometrial intraepithelial neoplasia **(EIN)** (8380/2), code 97. **Note 5:** **Remaining in situ histologies** * Code 97 for any remaining in situ histologies (/2) since the FIGO stage definitions do not include Stage 0.
