SEER EOD-88, 3rd Ed, 36
Question:
EOD-Extension--Head & Neck: In the absence of a clear surgical or pathologic description of how the salivary gland involvement relates to the head and neck primary, do we code the involvement as direct extension, further extension or metastasis? See discussion.
Discussion:
A composite resection of tonsillar mass and a modified radical neck dissection is performed. According to the pathology report: Squamous cell carcinoma involvement of tonsil with invasion of skeletal muscle. A separate specimen labeled "tumor" indicates a salivary gland is also involved with tumor. Neck dissection: 1 lymph node with metastasis.
Answer:
For cases diagnosed 1998-2003:
In the absence of a clear statement that the gland was involved by direct extension, code the EOD-Extension field to 85 [Metastasis]. In this case, the salivary gland tumor was described as a "separate specimen" that contained the salivary gland. The extension does not appear to be contiguous for this case.
If the salivary gland involvement had been by direct extension, which would be assumed if there had been contiguous involvement of the gland with the primary site, then code the EOD-Extension field to 80 [Further extension]. If there had been direct extension, the surgeon probably would not have dissected through the tumor. The resection specimens would have been contiguous.
