Malignant salivary gland tumours (staging)

Malignant salivary gland tumours are staged using the TNM staging system:

  • Tx: primary tumour cannot be assessed
  • T0: no evidence of primary tumour
  • T1
    • less than or equal to 2 cm in maximal diameter
    • no extra-parenchymal extension
  • T2
    • 2-4 cm in maximal diameter
    • no extra-parenchymal extension
  • T3
    • greater than 4 cm in maximal diameter OR
    • any size with extra-parenchymal extension
  • T4A: direct extension into skin, mandible, ear canal, facial nerve
  • T4B: direct extension into base of skull, pterygoid plates, or encases carotid artery

 

  • Nx: nodes cannot be assessed
  • N0: no evidence of nodal involvement
  • N1
    • single ipsilateral node
    • <3 cm in maximal diameter
  • N2A
    • single ipsilateral node
    • 3-6 cm in maximal diameter
  • N2B
    • multiple ipsilateral nodes
    • less than 6 cm in maximal diameter
  • N2C
    • contralateral or bilateral nodes
    • less than 6 cm in maximal diameter
  • N3: >6 cm in maximal diameter

 

  • Mx: presence of metastases cannot be assessed
  • M0: no evidence of metastases
  • M1: distant metastases present
