Notes

**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).
