Pathologic T
This input is used for staging
Notes
**Note 1:** Assign 88 for in situ cases (behavior code /2). TNM nor FIGO include an in situ category for sarcomas of the corpus. **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] or IIIC, 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:** Tumor size must be known to assign a value of T1a or T1b. You may use a physician’s statement of the T category if this is the only information in the medical record. * If the tumor appears to be in the T1 category, but no size or category is specified, assign T1NAACCR Item
NAACCR #880| Pathologic T | Pathologic T Display | Description | Registrar Notes |
|---|---|---|---|
| pX | pTX | Not defined by UICC* | Primary tumor cannot be assessed Pathologic classification criteria met, evaluation done: Physician unable to assess T Surgical resection of primary tumor, extension not stated Physician assigns cTX, no other information available to determine T |
| p0 | pT0 | Not defined by UICC** | No evidence of primary tumor |
| p1 | pT1 | Tumor limited to the uterus | Note: T1 has subcategories of T1a and T1b. Assign T1 only when there is no information available to assign one of the subcategories Tumor limited to uterus, NOS Invasive cancer tumor confined to corpus uteri Invasion of myometrium, NOS Localized, NOS Tunica serosa of the visceral peritoneum (serosa covering the corpus) Endocervical glandular involvement only Cervical stromal invasion Cervix uteri, NOS, but not beyond uterus Confined to uterus, size unknown FIGO Stage I [NOS] Stated as T1 [NOS] |
| p1A | pT1a | Tumor 5 cm or less in greatest dimension | Invasive cancer tumor confined to corpus uteri Confined to endometrium (stroma) Tumor invades less than one-half of myometrium Invasion of inner half of myometrium FIGO Stage IA Stated as T1a |
| p1B | pT1b | Tumor more than 5 cm in greatest dimension | Tumor invades one-half or more of myometrium Invasion of outer half of myometrium FIGO Stage IB Stated as T1b |
| p2 | pT2 | Tumor extends beyond the uterus, within the pelvis | Note: T2 has subcategories of T2a and T2b. Assign T2 only when there is no information available to assign one of the subcategories FIGO Stage II [NOS] Stated as T2 [NOS] |
| p2A | pT2a | Tumor involves adnexa | Adnexal involvement, NOS Extension or metastasis beyond uterus within pelvis: Adnexa Fallopian tube(s) Ligaments: Broad Round Uterosacral Ovary(ies) Parametrium Visceral peritoneum of pelvic organs excluding serosa of corpus uteri FIGO Stage IIA Stated as T2a |
| p2B | pT2b | Tumor involves other pelvic tissues | Extension to : Ureter Vulva Extension or metastasis to: Cul de sac (rectouterine pouch) Parietal serosa of pelvic cavity Pelvic wall(s) Vagina Described clinically as "frozen pelvis", NOS FIGO Stage IIB Stated as T2b |
| p3 | pT3 | Tumor involves abdominal tissues | Note: T3 has subcategories of T3a and T3b. Assign T3 only when there is no information available to assign one of the subcategories Stated as T3 [NOS] |
| p3A | pT3a | One site | Infiltration of abdominal tissues, one of the following sites: Abdominal serosa (visceral or parietal peritoneum of abdomen) Sigmoid colon Small intestine Other abdominal tissues FIGO Stage IIIA Stated as T3a |
| p3B | pT3b | More than one site | FIGO Stage IIIB Stated as T3b |
| p4 | pT4 | Tumor invades bladder or rectal mucosa | Invasion of: Bladder wall Bladder, NOS excluding mucosa Rectal wall Rectum, NOS excluding mucosa Extension to bowel mucosa or bladder (excluding bullous edema) Further contiguous extension FIGO Stage IVA Stated as T4 |
| 88 | 88 | Not applicable | In situ case but no pTis is defined by TNM Death certificate only (DCO) case |
| <BLANK> | BLANK | See Registrar Notes | Only information is FIGO Stage III [NOS], IIIC, 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 |
