Question:

Multiple primaries (Pre-2007)/EOD-Extension--Fallopian Tube: How many primaries are coded when endometrioid adenocarcinoma involves bilateral fallopian tubes? See Discussion.

Discussion:

The pathologist states "because of the intimate association with the luminal line of the fallopian tube it is felt that this represents synchronous primaries rather than mets." The SEER Code Manual only lists ovary, retinoblastomas, and Wilms Tumors under the bilateral code stated to be a single primary.

Answer:

For tumors diagnosed prior to 2007:

Complete two abstracts, one for left fallopian tube and one for right fallopian tube. This case has been determined to be two primaries by the pathologist. Bilateral involvement of paired sites (other than ovary, retinoblastoma and Wilms tumor) with the same histology within two months requires a determination of whether there are one or two primaries. The pathologist in the case above has made this determination.

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
