Pathologicl T

This input is used for staging


**Note 1:** High-grade squamous intraepithelial lesions (HSIL) and anal intraepithelial neoplasia (AIN) grade II-III are not normally collected by cancer registries. * AIN II-III or AIN III is reportable to standard-setters (except the Commission on Cancer) * Assign pTis if your registry collects these tumors **Note 2:** 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 3:** Assign the appropriate T category (T1, T2, or T3) based on the tumor size for the following descriptions Invasive tumor confined to mucosa, NOS (including intramucosal, NOS) Invades Lamina propria Muscularis mucosae Submucosa (superficial invasion) Muscularis propria (internal sphincter) Ischiorectal fat/tissue Perianal skin Perirectal skin Rectal mucosa or submucosa Rectal wall Skeletal muscle(s): Anal sphincter (external) Levator ani Subcutaneous perianal tissue Confined to anus Localized, NOS **Note 4:** Code incidental finding of malignancy in hemorrhoid according to greatest extension of tumor into wall of anus. * Assign T1 for localized, NOS if extension not specified **Note 5:** Assign T4 for contiguous extension from the site of origin. Discontinuous involvement is assigned in M (distant metastasis).

<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)
