MP/H Rules/Multiple primaries--Kidney, renal pelvis: In a patient who was never disease free because of multiple recurrences of invasive transitional cell carcinoma of the bladder originally diagnosed in 2004, is an invasive high grade urothelial carcinoma of the renal pelvis diagnosed in 2010 a new primary? See Discussion.

Patient has invasive TCC of the bladder diagnosed in 2004, and has never been disease free.

In 2/18/10 a left renal pelvis wash showed urothelial carcinoma, high grade.

On 4/7/10 a nephroureterectomy revealed high grade urothelial carcinoma with sarcomatous and squamous differentiation invading through pelvic wall and perihilar soft tissue.

Is this a new renal pelvis primary?

For cases diagnosed 2007 or later, the renal pelvis is a new primary per rule M7. M7 will be better explained in the revised MP/H rules, but the rationale is that no field effect was present for more than 3 years. Although the bladder CA continued to recur, there were no other organs involved until 2010. M7 is intended to make the renal pelvis a new primary because there was no field effect (no organs other than bladder involved) for more than 3 years.

20100082 Ambiguous terminology/Reportability--Heme & Lymphoid Neoplasms: Should a case be accessioned as MDS, NOS when a consult uses ambiguous terminology (e.g., probable MDS) to describe the disease process and the bone marrow does not confirm the consult diagnosis? See Discussion. A patient is stated to have "probable MDS" by a hematology oncologist consult during an admission. A bone marrow biopsy was also performed during this admission, the final diagnosis on the pathology report is, "anemia and thrombocytopenia." The patient was not seen again by a hematology oncologist; however the patient's cardiology states, "BM biopsy was not clear whether this is MDS or another etiology."

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

This is not reportable. In effect, the original diagnosis was a rule/out MDS diagnosis. The bone marrow biopsy performed as part of the initial workup, proved that rule/out diagnosis was not valid. The subsequent statement confirms the diagnosis is not clear.

Histology--Heme & Lymphoid Neoplasms: How is histology coded for a pathologic diagnosis of "B-cell lymphoma, unclassifiable, with features intermediate between DLBCL and Burkitt lymphoma" that was clinically referred to as a "double hit lymphoma"?

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

Code histology to 9680/3 [diffuse large B-cell lymphoma (DLBCL)]. Per the Alternate Names section in the Heme DB, B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma is one of the synonyms for for DLBCL.

20100044 Primary site--Heme & Lymphoid Neoplasms: Should the primary site be coded to C499 [Blood vessels, NOS] for a case of intravascular large B cell lymphoma, Asian variant [9712/3] found in the bone marrow and liver? See Discussion. Patient has biopsy proven intravascular large B cell lymphoma, Asian variant, (9712/3) in bone marrow and liver. The Hematopoietic Database does not give a primary site code. Should the primary site be coded C49.9 because, by definition, this lymphoma arises in the blood vessels?

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

Code primary site to C499 [blood vessels]. The definition in the Heme DB does specify that this type of extranodal large B-cell lymphoma is characterized by lymphoma cells within the lumina of blood vessels with the exception of larger arteries and veins. The reason no primary site is specified is that Western variant can originate in the skin or CNS.

20100088 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a patient has 2005 diagnosis of multiple myeloma diagnosed returns in 2010 with extramedullary plasmacytoma and a bone marrow biopsy showing plasma cell dyscrasia that is clinically stated to "consistent with a relapse of myeloma"? See Discussion.

Patient was diagnosed in 2005 with multiple myeloma and following stem cell transplant 2005 was in complete remission.

On 2/1/10 an excisional biopsy of a soft tissue right flank mass showed plasmacytoma. On 3/2/10 the bone marrow biopsy was stated to be consistent with plasma cell dyscrasia. An outside attending physician stated the bone marrow biopsy was consistent with a relapse of myeloma. There was no radiologic evidence of disease elsewhere as of Feb 2010, only the soft tissue right flank mass. Patient initially presented for post-op radiation to the right flank and was treated 3/29/10. On 8/6/10 a biopsy of a right perinephric mass was positive for plasmacytoma. Subsequent xray on 8/16/10 of the right tibia and fibula showed lytic lesion consistent with progression of myeloma.

Using the Hematopoietic Database, the plasmacytoma in 2/1/10 is a second primary. How do the rules apply to the perinephric soft tissue disease and right tibia lesion? Are they separate new primaries? Or is all of this simply a recurrence of the original 2005 diagnosis as the attending physician states?

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

Accession a single primary with the histology coded to 9732/2 [multiple myeloma]. The disease discovered in 2010 represents further advancement of former disease. Per the Abstractor Notes section in the Heme DB, it states that bone marrow involvement, lytic bone lesions, and bone tumor masses of plasma cells are common. Under the Recurrence and Metastases section in the Heme DB it further states that extramedullary (in tissue other than the bone) involvement is a generally a manifestation of advanced disease. This case is an example of such a situation.

20100089 Primary site--Heme & Lymphoid Neoplasms: How is primary site coded when lymphoma is initially found in both lymph nodes and bone marrow, the pathology report is unavailable, and the physician only states that both areas are involved? See Discussion. For many consultations and/or class 2 cases, the pathology report is not available to help determine the primary site. Should the primary site be automatically coded to C421 over C77_ when both are involved? The Abstractor Notes state the primary site can be either bone marrow or lymph nodes. The physician states only that both are involved.

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

Because both the bone marrow and LN are involved, code the primary site to C779 [lymph nodes, NOS] per Rule PH22. You are to code specific nodes if a specific region is specified; however, if no region is specified, code to lymph node, NOS [C779]). When you are having problems coding primary site, go to Module 7 Primary Site Rules for Lymphomas Only. See Rule PH26. It states that you code the primary site to bone marrow when ONLY the bone marrow is involved.

20100061 MP/H Rules/Histology: The 2010 SEER Manual has omitted some useful information in the Histologic Type ICD-O-3 section, specifically the statement of "Do not revise or update the histology code based on subsequent recurrence(s)". Will this statement be added to the revisions of the MPH rules? See Discussion. Example: A 2005 diagnosis of left breast lobular carcinoma [8520/3], followed by a 2009 diagnosis of left breast ductal carcinoma [8500/3]. Rule M10 states this is a single primary, but there is no information in the Histology rules (Multiple Tumors Abstracted as a Single Primary) that the original histology should be retained, thus a person could potentially use these rules to change the original histology to 8522/3 [duct and lobular carcinoma] per rule H28. We will reinstate the instruction not to change the histology code based on recurrence in future versions of the histology coding instructions. However, this instruction may not be applicable to all anatomic sites. It will be reinstated on a site-by-site basis. You may also refer to the instructions on Page 7 of the 2010 SEER Manual under the heading "Changing Information on the Abstract." 2010

MP/H Rules/Primary site--Kidney, Renal Pelvis: Should the primary site be changed to C689 [Urinary system, NOS] for a primary renal pelvis tumor after additional tumors are found months later in different urinary sites (e.g., bladder or ureter) and the MP/H Rules indicate these are all the same primary? See Discussion.

In a patient is diagnosed 1/29/08 with an invasive grade 3 of 3 papillary urothelial cell carcinoma arising in the depth of a calyx in mid portion of kidney, the primary site was coded C659 [Renal pelvis]. In 6/1/09 a TURBT showed three separate lesions on the right side of the bladder. The final diagnosis was high grade urothelial carcinoma in-situ with three tumors, the largest being 7mm. Per rule M8, the renal pelvis primary and subsequent bladder tumors are the same primary. Would the primary site be changed to C689 [Urinary system, NOS] when the bladder tumors were identified? Or is C689 only coded if more than one primary site is involved at diagnosis?

For cases diagnosed 2007 or later, Rule M8 applies. This is a single primary. The primary site was coded to C659 in 2008. Do not change the primary site code.

20100073 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a patient is diagnosed on 4/7/10 by a bone marrow biopsy with myelodysplastic syndrome, refractory anemia (RAEB2) and on a 7/27/10 bone marrow biopsy with progression to acute myelogenous leukemia with 40% blasts (AML)?

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

Accession two primaries per Rule M10, the first is a chronic neoplasm RAEB2 [9983/3] and the second is an acute neoplasm AML, NOS [9861/3]. Rule M10 states abstract as multiple primaries when a neoplasm is originally diagnosed in a chronic phase (MDS RAEB2) and an acute disease (AML) is diagnosed more than 21 days later. This is the rule that fits your case.

There are several important pieces of information. There were two bone marrows biopsies; one confirmed the chronic disease and a second confirmed the acute disease. The dates of the bone marrows are more than 3 months apart. Because you have a chronic and an acute disease, Rules M8-M13 in the coding manual apply.

20100083 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned for a patient with a longstanding history of follicular cell non-Hodgkin lymphoma followed by a 2010 diagnosis of "B-cell lymphoma with prominent large cell component, compatible with primary cutaneous follicle center cell lymphoma"? See Discussion.

Patient has a history of follicular cell non-Hodgkin lymphoma dating back to the 1990s. The patient was treated with chemotherapy and bone marrow transplantation, radiation and rituximab. The patient had no evidence of recurrence. In April 2010 a lesion appeared on the side of the scalp above the left ear with a diagnosis of "B-cell lymphoma with prominent large cell component, compatible with primary cutaneous follicle center cell lymphoma." The oncology diagnosis is "primary cutaneous follicle center lymphoma."

Would the Multiple Primaries Calculator be used in this case?

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

Accession two primaries per Rule M15. Per the Multiple Primaries Calculator, primary cutaneous follicle center lymphoma [9597/3] following a diagnosis of follicular lymphoma, NOS [9690/3] is a new primary.

While the pathologic diagnosis was B-cell lymphoma "compatible with" primary cutaneous follicle center cell lymphoma and ambiguous terms cannot be used to identify a more specific histology, the physician confirmed the more specific diagnosis without ambiguous terminology. Therefore, this diagnosis should be coded.
