Pathologic TNM staging of lacrimal gland carcinoma, AJCC 7th edition
Definition / general
- Applies to both clinical and pathologic staging
Primary tumor (T)
- TX: Primary tumor cannot be assessed
- T0: No evidence of primary tumor
- T1: Tumor 2 cm or less in greatest dimension, with or without extraglandular extension into the orbital soft tissue
- T2: Tumor more than 2 cm but not more than 4 cm in greatest dimension
- T3: Tumor more than 4 cm in greatest dimension
- T4: Tumor invades periosteum or orbital bone or adjacent structures
- T4a: Tumor invades periosteum
- T4b: Tumor invades orbital bone
- T4c: Tumor invades adjacent structures (brain, sinus, pterygoid fossa or temporal fossa)
- Notes:
As the maximum size of the lacrimal gland is 2 cm, T2 and greater tumors will usually extend into the orbital soft tissue
Regional lymph nodes (N)
- NX: Regional lymph nodes cannot be assessed
- N0: No regional lymph node metastasis
- N1: Regional lymph node metastasis
Stage grouping
- No stage grouping is presently recommended by AJCC 7th edition
