Pathologic Stage Classification (AJCC 8e):
+ Modified classification:
r (recurrent
y (post-neoadjuvant therapy)
- Primary tumor (pT):
pT3: Tumors limited to the mucosa and immediately underlying soft tissue, regardless of thickness or greatest dimension; for example, polypoid nasal disease, pigmented or nonpigmented lesions of the oral cavity, pharynx, or larynx
pT4a: Moderately advanced disease: Tumor involving deep soft tissue, cartilage, bone, or overlying skin
pT4b: Very advanced disease. Tumor involving brain, dura, skull base, lower cranial nerves (IX, X, XI, XII), masticator space, carotid artery, prevertebral space, or mediastinal structures
pT4 (subgroup cannot be determined)
+ T suffix:
m (multiple primary tumors)
- Regional lymph nodes (pN):
pN not assigned (no nodes submitted or found)
pN not assigned (cannot be determined based on available pathological information)
pN0: No regional lymph node metastasis
pN1: Regional lymph node metastases present
+ N suffix:
(sn) Sentinel node procedure
(f) FNA or core needle biopsy
- Distant metastasis (pM):
Not applicable - pM cannot be determined from the submitted specimen(s)
