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 regional lymph nodes. **Note 4:** 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 5:** For the following descriptions, assign the appropriate T category (T1, T2 or T3) based on the tumor size. Adjacent connective tissue EXCLUDING deep fascia Lesion(s) confined to dermis Subcutaneous tissue (through entire dermis) Confined to scrotum 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 |
Deep fascia, skeletal muscle Adjacent organs/structures Male genital organs: Epididymis Penis Prostate Spermatic cord Testis Underlying cartilage, bone Further contiguous extension Other organs and structures in male pelvis: Bladder Rectum Urethra Stated as T4 |
| 88 | 88 | Not applicable | Death certificate only (DCO) case |
| <BLANK> | BLANK | See Registrar Notes | Pathologic classification criteria not met Pathologic classification criteria met, evaluation done: Results not documented in patient record No surgical resection of known primary tumor (not T0) 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 Only Pathologic Stage Group documented (no T, N, or M information available) |
