#2: Heme & Lymph Manual & DB
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
This case was originally diagnosed in 2009, prior to the development of Hematopoietic Database. Therefore it is necessary to use the ICD-O-3 to code histology to 9684/3 [diffuse large B-cell lymphoma, immunoblastic]. Use the original histology diagnosed for the merged record because DLBCL, immunoblastic, and plasmablastic lymphoma are considered the same primary. Do not change the histology to code 9735/3 [plasmablastic lymphoma].
SEER*Educate provides training on how to use the Heme Manual and DB.
