20130104 Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for a diagnosis of intrasinusoidal diffuse large B-cell lymphoma involving lymph nodes, the liver and the bone marrow? See Discussion.

Intrasinusoidal DLBCL was diagnosed by liver biopsy. The bone marrow was involved based on abnormal cytogenetic findings. Per a physician's note, a PTA CT Abd/Pelvis showed hepatosplenomegaly and mild periportal/peripancreatic lymphadenopathy. A GI physician stated the lymphoma involves the veins of the liver.

Should the primary site be coded to the liver [C220] and the histology to 9680/3 [DLBCL]?

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Code the primary site to the intra-abdominal lymph nodes [C772] per Rule PH20.

Code the primary site to the specific lymph node region when multiple lymph node chains within the same region as defined by the ICD-O-3 are involved. Periportal and peripancreatic nodes are both intra-abdominal region nodes.

Based on the information provided, there is involvement of lymph nodes, the liver, spleen and bone marrow, but no other documentation of the primary site. Given that a primary lymphoma of the liver is very rare; it is unlikely that this lymphoma arose from the liver. Involvement of the liver and spleen is very common for patients with lymphoma. The involvement of the liver, spleen and bone marrow is coded in the CS fields as Stage IV involvement.

Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded if a patient with a history of chemotherapy treated "groin" lymphoma, subsequently has bone biopsies that demonstrate diffuse large B-cell lymphoma? See Discussion.

3/2012: Patient states he has a past history of lymphoma of the "groin." A bone biopsy of the right tibia done at this facility showed diffuse large B-cell lymphoma. There was no palpable lymphadenopathy on 03/2012. There is no other information available regarding the initial diagnosis except that the patient was treated with only chemotherapy.

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Code the primary site to C774 [inguinal lymph nodes] per Rule PH18. Code the primary site to inguinal lymph nodes [C774] when the site of lymphoma is described only as an inguinal mass. Groin lymph nodes are inguinal lymph nodes.

The diffuse large B-cell lymphoma diagnosed by right tibia biopsy is not a new primary per rule M7 because the histology of the history only case would be coded as 9590/3 [lymphoma, NOS]. No more specific histology is known for the initial diagnosis. Accession a single primary when a more specific histology [DLBCL] is diagnosed after the NOS ONLY histology when the Heme DB Multiple Primaries Calculator confirms the NOS and the more specific histology are the same primary. The right tibial involvement is not used to code the primary site because the patient had chemotherapy for this groin lymphoma prior to diagnosis of DLBCL.

20130211 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are reported if a bone marrow shows low grade mature B cell lymphoma with IgM paraprotein - macroglobulinemia? See Discussion.

Physician note: Bone marrow shows 10% involvement with low grade lymphoma. Assessment: Low grade mature B cell lymphoma with IgM paraprotein - macroglobulinemia.

The multiple primaries calculator indicates two primaries are to be reported. However, the physician stated that Waldenstrom's macroglobulinemia is another name for this patient's lymphoma.

There were no enlarged lymph nodes seen on the CT scan. The proposed treatment for this patient is Rituxan for the macroglobulinemia.

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 a single histology. The bone marrow initially showed a non-specific B-cell lymphoma. WM is a type of B-cell neoplasm. After immunophenotyping, a more specific histologic diagnosis of WM was made. In this case a single histology (WM) is diagnosed by the definitive diagnostic method (serum paraprotein demonstrating IgM), so it accessioned as a single primary.

Per PH16, code the histology to 9761/3 [Waldenstrom Macroglobulinemia (WM)] and the primary site to C420 [blood].

Primary site--Heme & Lymphoid Neoplasms: Does Rule PH27 apply meaning that primary site is coded to C809 or would it be more appropriate to code to C269 GI Tract NOS since all disease involves the GI tract and this is more specific?

Extranodal lymphoma first diagnosed in the stomach (fundus and antrum) which upon further investigation also involved the small bowel (MALT Lymphoma) in the absence of lymph node findings. MD staged this IIE. Initial thought was Gastric, but PET/CT indicated abnormal uptake involving loop of distended small bowel in the pelvis.

Assign C269 for Gastrointestinal tract, NOS. Apply Rule PH24, code to the organ when only an organ is involved. This rule can be used for NOS sites such as GI tract, NOS.

Based on the information provided, this lymphoma is confined to the GI tract -- stomach and small bowel.

Reportability--Heme & Lymphoid Neoplasms: Is "indolent multiple myeloma" reportable and synonymous with "indolent/smoldering myeloma"? See Discussion.

7/10/12 Diagnosed with monoclonal gammopathy of undetermined significance (MGUS)

7/27/12 Diagnosed with MGUS/smoldering myeloma. There was no intervention at this time.

In about October/November 2012 the diagnosis was reported as smoldering myeloma,.

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Indolent myeloma [9732/3] and smoldering myeloma [9732/2] are reportable terms synonymous with plasma cell myeloma. Monoclonal gammopathy of undetermined significance (MGUS) [9765/1] is not reportable.

20130221 MP/H Rules/Multiple primaries--Prostate: How many primaries are accessioned for a diagnosis of metastatic small cell neuroendocrine carcinoma of the prostate following a previous diagnosis of adenocarcinoma of the prostate? See Discussion.

Would a second prostate primary with histology coded to 8041/3 [small cell carcinoma] be accessioned for the following examples? Or are these metastases despite the different histologies?

Example 1: Prostate adenocarcinoma diagnosed in 2001, no treatment given. Metastatic small cell neuroendocrine carcinoma diagnosed 03/2012 on liver biopsy with a physician's statement in 4/2012 that the prostate is likely the cause of the metastasis to the liver.

Example 2: Prostate adenocarcinoma diagnosed in 2006, treated with TURP. Bone marrow biopsy in 5/2012 shows involvement by metastatic small cell carcinoma with morphologic and immunophenotypic features that argue against prostatic adenocarcinoma. The oncologist assessment states, "The patient has Stage 4 small cell carcinoma of the prostate and the bone marrow biopsy path shows metastatic small cell carcinoma (likely prostate in origin)."

Accession two primaries, adenocarcinoma [8140/3] of the prostate [C619], followed by small cell (neuroendocrine) carcinoma [8041/3] of the prostate [C619] for each of the examples given per Rule M10.

In each case, the second histology (because it is not adenocarcinoma) is a new prostate primary. Small cell carcinoma and small cell neuroendocrine carcinoma are not adenocarcinomas. As a result they are not covered by Rule M3.

20130136 Multiple primaries--Heme & Lymphoid Neoplasms: If a neoplasm is listed under the Transformations section in the Heme DB, is this always a new primary? See Discussion.

Where are the instructions for coding transformations? When a disease is listed under the transformations, the Multiple Primaries Calculator states it is a new primary. Is this a new primary when the physician calls it a transformation?

For example, patient was diagnosed in 2000 with chronic lymphocytic leukemia (CLL). A biopsy of a stomach mass on 4/26/12 was positive for diffuse large B-cell lymphoma. DLBCL is listed under the Transformations To section in the Heme DB for CLL. Is this a new primary because it is a transformation?

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Transformations do not always indicate a multiple primary is to be reported. Always apply the M Rules to determine the number of primaries. Refer to Rules M8-M13 in the Heme Manual address to determine the number of reportable primaries when chronic and acute neoplasms (transformations) are indicated on a case. Do not use the MP Calculator to determine the number of primaries unless the M Rules direct you to use it.

This case should be accessioned as two primaries, chronic lymphocytic leukemia [9823/3] diagnosed in 2000, and diffuse large B-cell lymphoma [9680/3] diagnosed on 04/26/2012 per Rule M10. Abstract a new primary when a neoplasm is originally diagnosed as a chronic (less aggressive) neoplasm (CLL) and there is a second diagnosis of an acute neoplasm (DLBCL) more than 21 days later.

20130042 Reportability--Heme & Lymphoid Neoplasms: Is follicular lymphoma in situ reportable? See Discussion.

Parotid mass and intraparotid lymph node biopsy: Follicular lymphoma in situ (see note).

Note: The morphologic findings in conjunction with the results of immunohistochemical stains demonstrate focal follicular lymphoma in situ in a background of reactive follicular hyperplasia. Cytogenetic studies on the parotid mass demonstrated a normal karyotype. FISH analysis for BCL2 and BCL6 gene rearrangements has been requested and will be reported separately.

Per the Note under Case Reportability Instructions Rule 3 in the Hematopoietic and Lymphoid Neoplasm Manual, do not report in situ [/2] lymphomas. 2013
