II.1.9.1 Reportability - Benign/Borderline Brain and CNS Tumors

There is a standard difference in regard to reportability dates for Benign/Borderline Brain and CNS Tumors:

Any tumor with a behavior code of 0 or 1 will be collected for the following site codes based on ICD-O-3:

The histology codes (also based on ICD-O-3) have been expanded and are listed in Appendix V for ICD-O-3 Primary Brain and CNS Site/Histology Listing.

Juvenile astrocytomas/pilocytic astrocytomas should continue to be reported as 9421/3. Only benign brain tumor cases with a diagnosis year of 2001 forward are required to be reported to the CCR.Do not report benign brain tumor cases with an unknown year of diagnosis, unless you know that the year of diagnosis is 2001 forward. Apply the rules under Section III.3.3.2 - Vague Dates to determine a date of diagnosis if it is known that the benign brain case was diagnosed after 2001.

Reportable Terminology

In order to be reportable, there must be a corresponding ICD-0-3 histology code for any CNS tumor related diagnosis.

 
Benign Schwannoma

Per SEER Instruction, we are to report Benign Schwannomas (9560/0) of the spinal cord (C72.0) and of the cranial nerves (C72.2 - C72.5); therefore, these are both reportable to the CCR.  Benign Schwannomas occurring anywhere else such as the peripheral nerves or peripheral nerve roots are not reportable to the CCR.  

Report spinal (Schwannoma) tumors (C72.0) when the tumor arises within the spinal dura or spinal nerve roots, or when they are stated to be “intradural” or “of the nerve root.”  DO NOT report tumors that arise in peripheral nerves.  Peripheral nerves are the portion of the nerve extending beyond the spinal dura.  

The cranial nerves (C72.2 – C72.5) are composed of twelve pairs of nerves that emanate from the nervous tissue of the brain.  Cranial nerves are sometimes referred to by their number, such as the 8th cranial nerve, instead of the vestibulocochlear nerve.

To assist registrars with identifying reportable benign Schwannoma tumors, the cranial nerve numbers, names and their ICD-O-3 topography codes are listed below:

 

Cranial Nerve Description

Associated ICD-O-3 Code

I

Olfactory (C72.2)

II

Optic (C72.3)

III

Oculomotor (C72.5)

IV

Trochlear (C72.5)

V

Trigeminal (C72.5)

VI

Abducens (C72.5)

VII

Facial (C72.5)

VIII

Vestibulocochlear (auditory and vestibular nerve, acoustic nerve) (C72.4)

IX

Glossopharyngeal (C72.5)

X

Vagus (C72.5)

XI

Accessory (C72.5)

XII

Hypoglossal (C72.5)

 

Example of a reportable Schwannoma:

Registrars are not expected to go back and review Schwannoma cases already submitted to the CCR.
