Question:

EOD-Extension--Lymphoma: How do you code stage and EOD for an extranodal lymphoma with bilateral involvement of a paired site? See discussion.

Discussion:

For example, we frequently see cases of lymphoma occurring in bilateral orbits, or both lungs. This issue was discussed at a 1991 SEER meeting with the tentative answer being that lymphoma involving both organs of a paired site will be coded as stage I (e.g., both eyes or both lungs), as this would be contiguous disease. However, an extranodal lymphoma involving tissue of both limbs (e.g., soft tissue of both arms) will be coded as stage IV because this represents wide areas of involvement that have no connection.

Answer:

For cases diagnosed 1998-2003:

Bilateral involvement of an extralymphatic paired organ is coded as involvement of a single extralymphatic organ or site for lymphomas. The EOD extension code would be at least 11 (Stage IE). Staging lymphomas of any site depends on whether one or more lymph node regions and/or extralymphatic organs are involved, and whether sites on one or both sides of the diaphragm are involved.
