Question
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if a patient is diagnosed in 2004 with extranodal diffuse large B-cell lymphoma (DLBCL) of the stomach followed by a 2011 diagnosis of DLBCL involving abdominal lymph nodes?



Discussion
In 2004 a patient’s extranodal DLBCL was treated with a partial gastrectomy at another facility. A recurrence of DLBCL was diagnosed in 2011 by a fine needle aspiration of abdominal lymph nodes. The patient presented to this facility for chemotherapy.



Answer
For cases diagnosed 2010 and forward, access the Hematopoietic Database at Click on Hematopoietic and Lymphoid Database. In the search box, enter your histology or the ICD-O-3 code. Click on the link to that disease. In the "Help me code for dx year" field, enter the year of diagnosis. The Hematopoietic Coding Manual (PDF) button will appear.

This case should be accessioned as a single primary, diffuse large B-cell lymphoma [9680/3] diagnosed in 2004. The steps used to arrive at this decision are:

Step 1: Enter diffuse large B-cell lymphoma in the Heme DB to find the histology. Click on the SEARCH button. "Diffuse large B-cell lymphoma (DLBCL)” [9680/3] appears on the screen under the NAME column. There was only one type of lymphoma diagnosed in this case; DLBCL was diagnosed in 2004 and 2011.

Step 2: Click on the HEMATOPOIETIC CODING MANUAL (PDF) button. Once in the manual, locate the Multiple Primary rules. The rules are intended to be reviewed in consecutive order from Rule M1-M15. Stop at the first rule that applies to the case you are processing. Stop at Rule M2. Abstract as a single primary when there is a single histology.



History
This SINQ question has been updated to the Hematopoietic & Lymphoid Neoplasm Manual & Database published January 2014. The original answer below was written based on the rules in 2010 For cases diagnosed 2010-2011, access the Hematopoietic Database at

http://seer.cancer.gov/tools/heme/.

Click on Hematopoietic Project. Click on Hematopoietic and Lymphoid Database. For 2010-2011 diagnoses, click on the "use the 2010 database" label in the upper right corner of the screen. The 2010 Hematopoietic Coding Manual (PDF) button will appear to indicate the correct version of the program is available now for query.

This case should be accessioned as a single primary, diffuse large B-cell lymphoma [9680/3] diagnosed in 2004. The steps used to arrive at this decision are:

Step 1: Enter diffuse large B-cell lymphoma in the Heme DB to find the histology. Click on the SEARCH button. Ensure that the term “Diffuse large B-cell lymphoma (DLBCL)” [9680/3] is highlighted on the screen. There was only one type of lymphoma diagnosed in this case; DLBCL was diagnosed in 2004 and 2011.

Step 2: Click on the 2010 HEMATOPOIETIC CODING MANUAL (PDF) button. Once in the manual, locate one of the three formats (i.e., flowchart, matrix or text) to check the Multiple Primary Rules. The rules are intended to be reviewed in consecutive order from Rule M1 to Rule M13. Stop at the first rule that applies to the case you are processing. Stop at Rule M2. Abstract as a single primary when there is a single histology.
