Pathologic T
This input is used for staging
Notes
**Note 1:** Over 90% of penile cancers are squamous cell carcinomas arising in the skin. Other cancers arising in the skin include adenocarcinomas (5%) arising in sweat glands, melanomas (2%, included in the Melanoma schema), and basal cell carcinoma (2%). About 1% of penile cancers are sarcomas, arising in subcutaneous connective tissues. **Note 2:** Verrucous carcinoma (M-8051) is a locally aggressive, exophytic, low grade carcinoma with minimal metastatic potential. **Note 3:** Assign Ta if a verrucous carcinoma is described as noninvasive or as having a broad pushing border or penetration. * If there is destructive invasion of verrucous carcinoma into structures in T1 or greater, assign the appropriate higher code **Note 4:** Information about involvement of the corpus spongiosum or corpus cavernosum is collected in this field for anatomic staging. This information is also collected in **Site-Specific Factor 10, Involvement of Corpus Spongiosum/Corpus Cavernosum** because involvement of these structures may have an independent effect on prognosis.NAACCR Item

| p1 | pT1 | Tumor invades subepithelial connective tissue# | Note: T1 has subcategories of T1a and T1b. Assign T1 only when there is no information available to assign one of the subcategories Invasive tumor limited to subepithelial connective tissue, but not involving corpus spongiosum or cavernosum If primary is skin: Invasive tumor limited to skin of penis, prepuce (foreskin) and/or glans Satellite nodules on prepuce or glans Confined to penis, NOS Localized, NOS UNKNOWN lymphovascular invasion Stated as T1 [NOS] |
| p1A | pT1a | Tumor invades subepithelial connective tissue WITHOUT lymphovascular invasion and is not poorly differentiated or undifferentiated |
T1 lesion WITHOUT lymphovascular invasion Stated as T1a |
| p1B | pT1b | Tumor invades subepithelial connective tissue WITH lymphovascular invasion or is poorly differentiated or undifferentiated |
T1 lesion WITH lymphovascular invasion Stated as T1b |
