Inquiry Details

Heme & Lymph Manual & DB
Question:
Discussion:
Patient was diagnosed in the blast phase of CML on a 4/2010 bone marrow biopsy. Pt failed Gleevec and progressed to the accelerated phase of CML in 10/2010.
Is this a single primary? This is not addressed in the hematopoietic rules. If this is a multiple primary, what rule should be applied?
Answer:
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per Rule M2 this is a single primary because there is only a single histology represented for this case.
Under the Alternate Names section in the Heme DB for chronic myelogenous leukemia (CML), NOS [9863/3 and chronic myelogenous leukemia, BCR-ABL1 positive [9875/3] it indicates CML-blast phase, CML-accelerated phase and CML-chronic phase are all synonyms for CML, NOS. Any combination of these terms diagnosed represents one disease process. The Gleevec was given to prevent or delay progression to the accelerated phase.
SEER*Educate provides training on how to use the Heme Manual and DB.

History:
For cases diagnosed 2010-2011, CML-blast phase, and CML-accelerated phase are synonyms for CML (the same disease). The Gleevec is given to prevent or delay progression to the accelerated phase.
The answers for SINQ questions with 2010 ID numbers were written using the 2010 Heme & Lymph Manual & DB. The instructions for using the 2010 Hematopoietic Database were written for the version of the software in use as of 5/24/2011. The user interface of the web-based 2010 Hematopoietic Database available from the SEER website varies slightly from the 5/24/2011 version in that the web-based version provides all the disease information in one scrollable window.
For cases diagnosed 2010-2011, access the 2010 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.
