Inquiry Details
References:
Heme & Lymph Manual & DB
Question:
Discussion:
The Heme DB identifies these as new primaries:
10/12/12 Large intestine, biopsy: Diffuse large B-cell lymphoma.
10/12/12 Bone marrow biopsy: Peripheral T-cell lymphoma.
Answer:
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per Rule M15, accession two primaries. According to Rule M15, use the multiple primaries calculator to determine the number of primaries for all cases that do not meet the criteria of M1-M14. Per the calculator, this scenario represents two primaries.
Assuming the only area of involvement is the large intestine, code the histology to 9680/3 [diffuse Large B-Cell Lymphoma] and per Rule PH24 code the primary site to C189 [colon, NOS]. According to PH24, one is to code the primary site to the organ when lymphoma is present only in an organ.
Rule PH26 applies to the second primary. Assuming the only area of involvement is the bone marrow, code the histology to 9702/3 [peripheral T-cell lymphoma] and code the primary site to C421 [bone marrow]. According to PH26, one is to code the primary site to bone marrow (C421) when lymphoma is present only in the bone marrow.
Rule M4 does not apply for this case. Rule M4 applied when you have two or more types of non-Hodgkin lymphoma in the same anatomic location. That is not the case in this scenario.
