Answer:
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph..
Per Rule PH30, use the Heme DB, determine the histology when rules PH1-PH29 do not apply. Code diffuse large B-cell lymphoma, germinal cell type to 9680/3 [diffuse large B-cell lymphoma (DLBCL)][9680/3]. Under the Alternate Names section of the Heme DB, these two terms are synonyms that share the same histology code.
SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms. Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx.
History:
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.
Code diffuse large B-cell lymphoma, germinal cell type coded to diffuse large B-cell lymphoma (DLBCL) [9680/3]. The steps used to arrive at this decision are as follows:
Enter in the Heme DB to find the histology. Click on the SEARCH button. Insure that the term "diffuse large B-cell lymphoma (DLBCL)" [9680/3] is highlighted on the screen under the RESULTS FOR ALL TERMS area.
Check the ALTERNATIVE NAMES section for synonyms. Note that germinal centreB-cell-like GBC is a synonym for DLBCL. Therefore, the histology code for both disease descriptions is 9680/3.
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.
. Abstract as a single primary when there is a single histology
