Question:

EOD-Extension--Lymphoma: How is the following guideline of "any mention of lymph nodes is considered indicative of involvement" applied for EOD-Extension of lymphoma cases when there is a discrepancy between physicians as to the stage at diagnosis? See discussion.

Discussion:

A biopsy of mesenteric nodes confirmed lymphoma. A bone marrow biopsy was negative. A CT of the chest indicates "small mediastinal and bilateral hilar nodes, but without convincing adenopathy." The case was Stage 2 per the oncologist and Stage 3 per the surgeon's TNM form.

Answer:

For tumors diagnosed 1998-2003:

Based on the information provided for this example, the lymphoma involves one site, mesenteric nodes. Code EOD extension as 10 [Involvement of a single lymph node region].

The statement "For lymphomas, any mention of lymph nodes is indicative of involvement" refers to the terms in the paragraph above it on page 8 of the EOD manual: Palpable, enlarged, visible swelling, shotty, lymphadenopathy. While these terms are ignored for other malignancies, they should not be ignored for lymphomas. None of these terms apply to the example provided here. According to the CT, the mediastinal and hilar nodes are "small" "without convincing adenopathy." In other words, the mediastinal and hilar nodes are negative.
