Status Final References Source 1: 2010 Heme & Lymph Manual & DB pgs: Notes: Source 2: pgs: Notes: Question Multiple primaries--Heme & Lymphoid Neoplasms: Is this a recurrence or a new primary? See discussion. Discussion Patient with an extranodal diffuse large B-cell lymphoma (DLBCL)treated with a partial gastrectomy at another facility in 2004. Recurrence of DLBCL in 2011, diagnosed by fine needle aspiration to abdominal lymph nodes, no further information as to where. The pt presents to my facility for a VAD insertion as well as chemo. I cannot find the rule that would help me if this is a recurrence or a new primary. Can you help me? Answer The 2011 diagnosis is a recurrence of the original diagnosis of DLBCL. Do not abstract a new primary. Use the 2010 Hematopoietic Manual for this case. Rule M2 states to abstract as a single primary when there is a single histology.
