Question:

Multiple primaries--Lymphoma: Is mediastinal large B-cell lymphoma followed by classical Hodgkin lymphoma reportable as one or two primaries? See Discussion.

Discussion:

Diagnosed 06/06/2006 with mediastinal large B-cell lymphoma, 9679/36. On 05/10/2007, another mediastinal lymph node biopsy done and the diagnosis was recurrent malignant lymphoma, classical Hodgkin's. A Hematopatholgy Consultant states, "it appears likely that the preceding mediastinal diffuse large B-cell lymphoma and the current classical Hodgkin's lymphoma are clonally related and represent different manifestations of the same entity. One might also place this in the spectrum of 'mediastinal gray zone lymphoma' described by Dr. Jaffee and colleagues."

Answer:

For cases diagnosed prior to 1/1/2010:Report this case as two primaries. Report non-Hodgkin lymphoma followed by Hodgkin lymphoma as separate primaries.

According to the Table of Single and Subsequent Primaries for Hematologic Malignancies, mediastinal large B-cell lymphoma and Hodgkin disease are "D" - Different disease processes.

For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
