California Cancer Reporting System Standards Volume I: Abstracting and Coding Procedures
The grading system of the French Federation of Cancer Centers Sarcoma Group (FNCLCC) is the preferred system.
Record the grade from any three-grade sarcoma grading system the pathologist uses.
For terms such as "well differentiated" or "poorly differentiated," see Section V.3.6.2.
In some cases, especially for needle biopsies, grade may be specified only as "low grade" or "high grade." The numeric grade takes precedence over “low grade” or “high grade.”
