SEER EOD-88, 3rd Ed, 111, 123. Note 6

Question:

EOD-Extension--Ovary: What code is used to represent this field for an ovarian primary presenting with "spread to the omentum"?

Discussion:

Answer:

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 75 [Peritoneal implants, NOS] because the size of the implants on the omentum is not known.

Note 6 was added to the EOD scheme which states that both direct extension and discontinuous metastasis to the omentum are coded in the range 70-75 depending on how the peritoneal implants are described.

History:

For cases diagnosed prior to 1998: Code involvement of the omentum as 75 [FIGO Stage III, NOS]. The omentum is an abdominal structure and spread to the abdomen is Stage III disease. If you have further information about the size of the metastases in the omentum, a more specific code in the range of 70-72 can be assigned.
