Inquiry Details
References:
SEER EOD-88, 3rd Ed, 136
Question:
EOD-Clinical Extension--Prostate: In the SEER EOD manual, there is a list of terms to distinguish apparent from inapparent tumor for prostate primaries. If a physician uses a term not currently on the list or if a physician uses a list in the "maybe" category, should we assume the tumor to be clinically inapparent or clinically apparent tumor?
Discussion:
Answer:
For cases diagnosed 1998-2003:
If the physician used a term not on the clinically apparent/inapparent list, ignore that term and use the best information available from other sources to code the EOD-Extension field.
If clarifying stage information is missing and the term is in the maybe category or the term is not on the list, then code EOD-Extension as 30 [localized, NOS] for cases that appear localized.
