Heme & Lymph Manual & DB, Appendix F
Question:
Discussion:
No exact match returned after entering the term "thrombocytopenia of unknown etiology" in the Heme DB. However, the program does indicate there are 17 results that could be displayed that show any of the 4 terms entered. Clicking on the search label indicates there are no matches either.
The only result returned after entering "thrombocytopenia" into the search box is "refractory thrombocytopenia."
Answer:
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
"Thrombocytopenia of unknown etiology" is not reportable. Thrombocytopenia refers to a low platelet count which causes bleeding. Thrombocytopenia can be caused by viral infections, excessive alcohol usage, HIV, and other causes (including chemotherapy). If the diagnosis is not "refractory thrombocytopenia" the case is not reportable. Appendix F lists this term as non-reportable.
If you do not see the term in the Heme DB under either the Name column or the Alternative Names section for the results returned, it is not reportable. The only reportable term that contains the word thrombocytopenia is refractory thrombocytopenia. Therefore, thrombocytopenia of unknown etiology is not reportable.

History:
This diagnosis is not reportable. Thrombocytopenia refers to a low platelet count which causes bleeding. Thrombocytopenia can be caused by viral infections, excessive alcohol usage, HIV, and other causes (including chemotherapy). If the diagnosis is not "refractory thrombocytopenia" the case is not reportable.
When searching for a diagnosis in the Heme DB, do not enter the entire diagnosis into the search engine. If the diagnosis existed, it would have displayed. The "show results of any term" label on the screen allows you to see any diagnosis in the database that contains one or more of the terms you typed in.
The correct way to perform the search is as you did on your second attempt using just the word . If you do not see the term in the Heme DB under either the RESULTS section or the ALTERNATIVE NAMES section for the result returned, it is not reportable. The only reportable term that contains the word thrombocytopenia is refractory thrombocytopenia. Therefore, thrombocytopenia of unknown etiology is not reportable.
