SSF 1 WHO Grade Classification



The citation in the CS Manual for the brain schema, SSF 1 - WHO Grade Classification, Note 2, has an error in the reference to a table in the AJCC Cancer Staging Manual, 7th edition. The correct reference is Table 56.3 WHO Grades of CNS Tumors, which is found on page 596 of the AJCC Cancer Staging Manual, 7th edition. The current citation in the CS Manual references Table 56.2. 




CS Manual, brain schema, SSF 1, Note 2:  Code the WHO grade classification as documented in the medical record. If a WHO grade is not documented, refer to the WHO grade instructions in Part I, Section II. For specific histologies, a WHO grade is automatically assigned. See AJCC 7th edition Table 56.3 or MPH rules Brain Section Equivalent Terms and Definitions.
