Pathologic T
This input is used for staging
Notes
**Note 1:** FIGO does not include an in situ category for tumors of the vulva, but TNM does. Assign pTis (behavior code /2) for in situ cases. **Note 2:** When both the Federation Internationale de Gynecologie et d'Obstetrique (FIGO) stage and extension information on the primary tumor are available, use the extension information to assign the T in preference to a statement of FIGO stage - see Registrar notes. * If the only information is (pathologic) FIGO III [NOS], IIIA, IIIB, IIIC, or IVA, assign the appropriate stage and leave pathologic T, N, and M blank. If the only information is (pathologic) FIGO stage IVB, leave pathologic T and N blank and see M **Note 3:** FIGO Stage I, IA and IB are defined by the following * Size of tumor * Involvement of vulva OR vulva and perineum * Depth of stromal invasion **Note 4:** The depth of invasion is defined as the measurement of the tumor from the epithelial-stromal junction of the adjacent most superficial dermal papilla to the deepest point of invasion. (1) **Note 5:** T3 is not used by FIGO. They label it T4. If you have a record which states T4, assign T3. (1) **Note 6:** FIGO Stage IVA is assigned based on tumor extension and/or regional lymph node involvement.NAACCR Item

| p1 | pT1 | Tumor confined to vulva or vulva and perineum# | Note: T1 has subcategories of T1a and T1b. Assign T1 only when there is no information available to assign one of the subcategories Vulva and perineum: Stromal invasion but depth of invasion in millimeters not stated Invasive carcinoma confined to: Musculature Submucosa Vulva including skin Confined to the vulva and perineum, size unknown Localized, NOS FIGO Stage I [NOS] Stated as T1 [NOS] |
| p1A | pT1a | Tumor 2 cm or less in greatest dimension and with stromal invasion no greater than 1.0 mm | Vulva and perineum: Stromal invasion less than or equal to 1 mm FIGO Stage IA Stated as T1a |
| p1B | pT1b | Tumor greater than 2 cm or with stromal invasion greater than 1 mm | Vulva and perineum: Stromal invasion greater than 1 mm FIGO Stage IB Stated as T1b |
| p2 | pT2 | Tumor of any size with extension to adjacent perineal structures: Anus Lower third urethra Lower third vagina |
Perianal skin Urethra, NOS Vagina NOS FIGO Stage II Stated as T2 |
| p3 | pT3 | Tumor of any size with extension to the following structures: Bladder mucosa Fixed to pelvic bone Rectal mucosa Upper 2/3 urethra Upper 2/3 vagina |
Bladder wall or bladder, NOS (including mucosa) Perineal body Rectal wall or rectum, NOS (including mucosa) Further contiguous extension Stated as T3 or T4 |
| 88 | 88 | Not applicable | Primary site/histology not TNM defined Death certificate only (DCO) case |
| <BLANK> | BLANK | See Registrar Notes | Only information is FIGO Stage III [NOS], IIIA, IIIB, IIIC, IVA, or IVB Pathologic classification not met Pathologic classification criteria met, evaluation done: Results not documented in patient record No surgical resection of known primary tumor (not T0) OR Resection insufficient for site-specific pathologic assessment No surgical resection of primary tumor and there isn't a positive biopsy of a structure in the highest T category and highest N category Evidence of metastatic disease (pM1), no other workup |
