Pathologic T
This input is used for staging
Notes
**Note 1:** 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], IIIC [NOS], IIIC1, or IIIC2, 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 2:** FIGO does not include an in situ category for tumors of carcinomas of the corpus uteri, but TNM does. Assign pTis and behavior code /2 for in situ cases. **Note 3:** To assign a T2 category, stromal connective tissue of the cervix must be involved; endocervical glandular involvement only is not classified as a T2 tumor in TNM. **Note 4:** Extension to the bowel or bladder mucosa must be proven by biopsy in order to rule out bullous edema.NAACCR Item

| pIS | pTis | Carcinoma in situ (preinvasive carcinoma) | Intraepithelial, noninvasive, preinvasive Stated as Tis |
| p1 | pT1 | Tumor confined to the corpus uteri | Note: T1 has subcategories of T1a and T1b. Assign T1 only when there is no information available to assign one of the subcategories Invasive cancer confined to corpus uteri Invasion of myometrium, NOS Endocervical glandular involvement WITH tumor invading myometrium, NOS or involvement of myometrium not known Localized, NOS FIGO Stage I [NOS] Stated as T1 [NOS] |
| p1A | pT1a | Tumor limited to endometrium or invading less than half of myometrium | Confined to endometrium (stroma) Tumor invades less than one-half of myometrium Invasion of inner half of myometrium Endocervical glandular involvement WITH tumor limited to endometrium or invading less than one-half of myometrium FIGO Stage IA Stated as T1a |
| p1B | pT1b | Tumor invades one half or more of myometrium | Tumor invades one-half or more of myometrium Invasion of outer half of myometrium Endocervical glandular involvement WITH tumor invading one-half or more of myometrium FIGO Stage IB Stated as T1b |
| p2 | pT2 | Tumor invades cervical stroma, but does not extend beyond the uterus | Cervix uteri, NOS, but not beyond uterus Cervical stromal invasion FIGO Stage II Stated as T2 |
| p3 | pT3 | Local and/or regional spread as specified below# | 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 | Tumor invades the serosa of the corpus uteri or adnexae (direct extension or metastasis) |
Extension or metastasis to Tunica serosa (visceral peritoneum of corpus, serosa covering the corpus) Tunica serosa of corpus WITHOUT involvement of cervix Extension or metastasis to: Adnexa: Fallopian tube(s) Ovary(ies) FIGO Stage IIIA Stated as T3a |
| p3B | pT3b | Vaginal or parametrial involvement (direct extension or metastasis) |
Extension or metastasis to: Bladder wall Bladder, NOS excluding mucosa Ligaments: Broad Round Parametrium, NOS Parietal serosa of pelvic wall Pelvic wall(s) Rectal wall Rectum, NOS excluding mucosa Vagina Visceral peritoneum of pelvic organs excluding serosa of corpus Extension to: Ureter Vulva Described clinically as "frozen pelvis", NOS FIGO Stage IIIB Stated as T3b |
| p4 | pT4 | Tumor invades bladder/bowel mucosa | Extension to bowel mucosa or bladder mucosa (excluding bullous edema) Further contiguous extension Abdominal serosa (visceral or parietal peritoneum of abdomen) Cul de sac (rectouterine pouch or Pouch of Douglas) Sigmoid colon Small intestine FIGO Stage IVA Stated as 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], IIIC [NOS], IIIC1, IIIC2, 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 |
