Neck Cancers

Determining the Grade of the Tumor

All sarcomas should also be given a grade based on factors seen under the microscope. They can be designated as low grade or high grade.

There is also a three-tiered system based on a number of factors (differentiation, mitotic activity and necrosis). Each of these factors is given a score of 1 to 3 and tallied for a final grade:

  • Grade 1: Score of 2 or 3
  • Grade 2: Score of 4 or 5
  • Grade 3: Score of 6 to 8
