Pathologic T
This input is used for staging
Notes
**Note 1:** FIGO nor TNM include an in situ category for tumors of the placenta. 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 Stage III [NOS], IIIA, IIIB, or IV [NOS], IVA, or IVB, leave T blank and see M **Note 3:** Genital metastasis (vagina, ovary, broad ligament, fallopian tube) is classified T2. Any involvement of non-genital structures, whether by direct invasion or metastasis is described using the M (distant metastasis) classification. **Note 4:** For T, substaging is determined by the values in **Site-Specific Factor 1, Prognostic Scoring Index**.NAACCR Item
NAACCR #880| Pathologic T | Pathologic T Display | Description | Registrar Notes |
|---|---|---|---|
| pX | pTX | 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 | No evidence of primary tumor | |
| p1 | pT1 | Tumor confined to uterus | Confined to: Cervix Corpus Placenta Localized, NOS FIGO Stage I [NOS], IA, or IB Stated as T1 |
| p2 | pT2 | Tumor extends to other genital structures: Vagina Ovary Broad ligament Fallopian tube by metastasis or direct extension |
Adjacent connective tissue, NOS Genital structures, NOS by direct extension or metastasis Further contiguous extension FIGO Stage II [NOS], IIA, or IIB Stated as T2 |
| 88 | 88 | Not applicable | Primary site/histology not TNM defined In situ case but no pTis is defined by TNM Death certificate only (DCO) case |
| <BLANK> | BLANK | See Registrar Notes | Only information is Stage III [NOS], IIIA, IIIB, or IV [NOS], 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 |
