Question

Reportability--Brain and CNS: Why has reportability changed for "intradural extramedullary schwannomas"? Are all "spinal" schwannomas reportable or only those stated to be "intradural"? See Discussion.



Discussion

If intradural schwannomas are to be collected for cases diagnosed 2011 and later, why were they not included in the 2012 SEER Manual? Should collection of spinal schwannomas be postponed until the next revision of the MP/H Rules?



Answer

The reportability of schwannomas was not initially agreed upon by the standard setters. After the issue was discussed by the CoC, NPCR and SEER Technical Workgroup and an agreement was reached. See #2 under Reportability in the Data Collection Answers from the CoC, NPCR, SEER Technical Workgroup http://www.seer.cancer.gov/registrars/data-collection.html#reportability.

The most accurate and most current instruction is to report these spinal tumors when they arise within the spinal dura or spinal nerve roots, or when they are stated to be "intradural" or "of the nerve root." Do not report these tumors when they arise in the peripheral nerves. The peripheral nerves are the portion of nerve extending beyond the spinal dura.

Spinal cord intradural schwannomas originate in spinal nerve roots. Spinal nerve root is best classified as spinal cord, C720.
