Question:

Grade, Differentiation--Brain and CNS: Can grade IV be implied for brain primaries with the histology of glioblastoma multiforme, even if there is no statement of grade in the path report? See discussion.

Discussion:

Dr. Platz has instructed the Iowa registry to code glioblastoma multiforme to grade IV, even when there is no corroborating statement of grade in the path report. This is also supported in some references.

Answer:

Code the Grade, Differentiation field to 9 [Cell type not determined, not stated or not applicable] in the absence of a stated grade on the pathology report. If a grade is stated, code the stated grade. SEER does not recommend adopting the rule in the Discussion.
