Pathologic T
This input is used for staging
Notes
**Note 1:** In the case of multiple simultaneous tumors, code the tumor with the greatest extension. **Note 2:** Skin ulceration does not alter the T category. **Note 3:** In-transit metastasis is coded in N (regional lymph nodes). **Note 4:** The depth of stromal 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. **Note 5:** Assign T4 for tumors involving fascia or musculature of vulva and perineum. **Note 6:** Tumor size must be known to assign a value of T1, T2 or T3. 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, T2 or T3 categories, but no size or category is specified, assign TX **Note 7:** For the following descriptions, assign the appropriate T category (T1, T2 or T3) based on the tumor size. Submucosa invasion Confined to vulva, NOS Localized, NOSNAACCR 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 Tumor size (TS) unknown for T categories where TS needed to determine T Physician assigns pTX, no other information available to determine T |
| p0 | pT0 | No evidence of primary tumor | |
| pIS | pTis | Carcinoma in situ | Intraepidermal, intraepithelial, noninvasive Stated as Tis |
| p1 | pT1 | Tumor 2 cm or less in greatest dimension | Stated as T1 |
| p2 | pT2 | Tumor more than 2 cm but not more than 5 cm in greatest dimension | Stated as T2 |
| p3 | pT3 | Tumor more than 5 cm in greatest dimension | Stated as T3 |
| p4 | pT4 | Tumor invades deep extradermal structures, i.e., cartilage, skeletal muscle, fascia, or bone |
Anus Bladder wall or bladder Extension to underlying cartilage, bone Fascia Fixed to pubic bone Musculature, skeletal muscle Perianal skin Perineal body Rectal mucosa Rectal wall or rectum, NOS excluding mucosa Urethra Vagina Further contiguous extension Stated as T4 |
