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
Distant metastasis (M)
  • M0: No distant metastasis
  • M1: Distant metastasis
Stage grouping
  • No stage grouping is presently recommended by AJCC 7th edition
