Question:
Discussion:
5/14/12 Bone marrow biopsy: Acute myeloid leukemia (AML).
5/21/12 Oncology consult: AML with 30-40% blasts and evidence of del(20q) and del(5q), is suggestive of an underlying myelodysplastic syndrome (MDS). Hence the patient has secondary AML.
If these are two primaries, how are the diagnosis dates coded?
Answer:
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
This case is accessioned as a single primary diagnosed on 5/14/12 as acute myeloid leukemia with myelodysplasia-related (e.g., del(5q)) changes [9895/3] per Rule M2. The patient was diagnosed with a single histology, acute myeloid leukemia with myelodysplasia-related changes per the submitted information.

History:
This is one primary, Acute Myeloid Leukemia, 5/14/12.
Per Rule M8, abstract as a single primary when both a chronic (MDS) and an acute (AML) neoplasm are diagnosed at the same time and there is only one positive bone marrow biopsy.
