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 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:** Extension to the bowel or bladder mucosa must be proven by biopsy in order to rule out bullous edema.

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, T1b and T1c. 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 WITH or WITHOUT involvement of endocervix Tunica serosa of the visceral peritoneum (serosa covering the corpus) Cervix uteri, NOS, but not beyond uterus Localized, NOS FIGO Stage I [NOS] Stated as T1 [NOS]
p1A	pT1a	Tumor limited to the endometrium/endocervix	Confined to endometrium OR endocervix (Glandular, stromal or both) FIGO Stage IA Stated as T1
p1B	pT1b	Tumor invades less than half of the myometrium	Tumor invades less than one-half of myometrium WITH involvement of endocervix FIGO Stage IB Stated as T1b
p1C	pT1c	Tumor invades one half or more of the myometrium	Invasion of outer half of myometrium WITH involvement of endocervix FIGO Stage IC Stated as T1c
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 within true 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 or metastasis to: Cul de sac (rectouterine pouch) Pelvic wall(s) Parietal serosa of pelvic cavity Ureter Vagina Vulva 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. Abdominal tissues involvement, NOS Further contiguous extension 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 structures 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) 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

\* TX is not defined by UICC in the 7th edition. Approval has been provided by UICC to use the standard definition "Primary tumor cannot be assessed," as TX. \** T0 is not defined by UICC in the 7th edition. Approval has been provided by UICC to use the standard definition "No evidence of primary tumor," as T0.
