Pathologic T
This input is used for staging
Notes
**Note 1:** Assign 88 for in situ cases (behavior code /2). TNM does not include an in situ category for orbit sarcoma tumors. **Note 2:** The orbital tissues are the support systems of the globe, confined to the space within the surrounding bony structure. The orbital tissues include * Fat, striated and smooth muscle, and fibroconnective, vascular, lymphoid, peripheral nerve, and optic nerve tissue **Note 3:** Tis may be used only for *non-sarcoma* histologies coded to this site. * Sarcomas do not present as in situ or noninvasive tumorsNAACCR 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 | |
| p1 | pT1 | Tumor 15 mm or less in greatest dimension | Confined to orbit Localized, NOS Stated as T1 |
| p2 | pT2 | Tumor more than 15 mm in greatest dimension WITHOUT invasion of globe or bony wall |
Stated as T2 |
| p3 | pT3 | Tumor of any size WITH invasion of orbital tissues and/or bony walls |
Stated as T3 |
| p4 | pT4 | Tumor invades: Globe or periorbital structure, such as Eyelids Temporal fossa Nasal cavity Paranasal sinuses Central nervous system (CNS) |
Cranium Further contiguous extension Stated as T4 |
| 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 | 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) |
