Primary tumor (T)
  • TX: Primary tumor cannot be assessed
  • T0: No evidence of primary tumor
  • Tis: Carcinoma in situ
  • T1: Tumor 5 mm or less in greatest dimension, not invading the tarsal plate or eyelid margin
  • T2a: Tumor more than 5 mm, but not more than 10 mm in greatest dimension, or any tumor that invades the tarsal plate or eyelid margin
  • T2b: Tumor more than 10 mm, but not more than 20 mm in greatest dimension, or involving the full thickness eyelid
  • T3a: Tumor more than 20 mm in greatest dimension, or any tumor that invades adjacent ocular or orbital structures, or any T with perineural tumor invasion
  • T3b: Complete tumor resection requires enucleation, exenteration or bone resection
  • T4: Tumor is not resectable due to extensive invasion of ocular, orbital, craniofacial structures or brain
Regional lymph nodes (N)
  • NX: Regional lymph nodes cannot be assessed
  • cN0: No regional lymph node metastasis, based on clinical evaluation or imaging
