20100040 Histology--Heme & Lymphoid Neoplasms: How is this field coded for a patient with a negative bone marrow and multiple plasmacytomas in different bone sites (e.g., thoracic vertebrae and left femur)?

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

Code the primary site to C419 [Bone, NOS] and the histology to 9731/3 [solitary plasmacytoms].

The vertebral lesions are common for plasmacytomas, as are lesions of the femur. If the patient does not meet the criteria of plasma cell myeloma/multiple myeloma (which is 20% of the leukocyte differential count), do not code the histology to multiple myeloma.

Per Rule M2, abstract a single primary when there is a single histology.

Per Rule PH3, code the primary site to the where the plasmacytoma originated and code the histology of bone () when the diagnosis is multiple plasmacytomas of the bone.

Reportability--Heme & Lymphoid Neoplasms: Given that there appears to be many differences in the reportability of these case types pre- and post-2010 (e.g., [refractory] thrombocytopenia), is there a list available that gives the reportability dates for these diseases? See Discussion.

For cases diagnosed prior to 2010 "thrombocytopenia" was not reportable. According to the Heme Database, the term "refractory thrombocytopenia" is now reportable for cases diagnosed 1/1/10 and later. It would be helpful to have a list of diagnosis date requirements for the different hematopoietic diseases.

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

Thrombocytopenia (NOS) is not reportable per Appendix F. However, the term "refractory thrombocytopenia" [9992/3] is reportable for cases diagnosed 2010 or later.

There has been no change in the reportability for thrombocytopenia. The hematopoietic "help" system lists all of the synonyms, variants, and abbreviations for diseases.

See the Hematopoietic & Lymphoid Neoplasm Coding Manual for changes in reportability associated with these cases.

 

  • Appendices D1a and D1b provide all of the new histology terms and codes.

  • Appendix D2 lists the newly reportable conditions.

    • Terms and codes in Appendix D are effective 01/01/10 and later. Refractory thrombocytopenia is included in D1a and D1b. The notes for D1a and D1b provide explanation and reiterate the dates these terms are effective.

    		20100107 MP/H Rules/Histology--Kidney, renal pelvis: How is histology coded for a tumor described as "renal cell carcinoma, clear cell with rhabdoid features"? See Discussion.

    Is the statement "with __ features" indicative of a specific type of renal cell carcinoma (that is not represented by a specific histology code) or a second histologic type? Per ICD-O, "malignant rhabdoid tumor" is coded 8963/3. "Rhabdoid" is not listed in Table 1 in the MP/H rules as a specific type of renal cell carcinoma.

    Rhabdoid features occur in about 5% of all renal cell cancers and indicate a more aggressive tumor. Per WHO, these tumors comprise approximately 2% of all pediatric tumors with a median diagnosis age of 1-2 years old. This diagnosis is highly suspect in patients over age 3. Most previously reported rhabdoid tumors over age 5 have subsequently proven to be renal medullary carcinomas.

    For cases diagnosed 2007 or later, if the patient in this case is a child, apply Kidney Rule H7 and code histology to 8963/3 [malignant rhaboid tumor]. Otherwise, we strongly suggest you consult with the pathologist to determine if this is truly a rhabdoid rather than a medullary tumor.

    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.

    Reportability--Heme & Lymphoid Neoplasms: Is "myeloproliferative syndrome, NOS" synonymous with "myeloproliferative syndrome" and "myeloproliferative disease" and, therefore, reportable under the new hematopoietic rules?

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

    Myeloproliferative syndrome and the myeloproliferative diseases were used in the past to describe myeloproliferative neoplasms. For cases diagnosed 2010 and forward, although the term "myeloproliferative syndrome" is not currently used to describe this disease, the synonyms "myeloproliferative syndrome" and "myeloproliferative disease" were added to the database for myelodysplastic/myeloproliferative neoplasm, unclassified [9975/3].

    		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.

    MP/H Rules/Multiple primaries--Kidney: In a patient with a history of renal cell carcinoma, would a new primary be accessioned per Rule M10 for a soft tissue mass in the renal fossa not stated to be a metastasis but that was referred to as recurrent renal cell carcinoma, clear cell per the excision pathology report? See Discussion.

    This patient was diagnosed with clear cell carcinoma of the right kidney in 2003, treated with nephrectomy. The tumor was limited to the kidney. An FNA of the pancreas in 11/07 was consistent with metastatic renal cell carcinoma. In 2009 the patient was diagnosed with a right renal fossa mass by CT. The mass was excised on 8/26/09 and showed, "recurrent renal cell ca, clear cell." The path specimen was labeled as, "soft tissue, rt renal fossa." The original 2003 slides were not reviewed and the renal fossa mass was not described as being metastatic.

    If the renal fossa soft tissue mass is a new tumor, the MP/H rules for Other Sites directs you to code it as a new primary per rule M10 [Tumors diagnosed more than one (1) year apart are multiple primaries]. Would this be a new soft tissue tumor per rule M10? Or would this be a recurrence of the original kidney primary?

    For cases diagnosed 2007 or later:

    This is not a new primary. The patient has metastatic disease from the 2003 kidney primary. Clear cell carcinoma metastasized to the pancreas in 2007 and to the right renal fossa in 2009.

    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.

    		20100092 Primary site--Heme & Lymphoid Neoplasms: Should the primary site for the follicular lymphoma diagnosis be coded to C779 [Lymph nodes, NOS] when a bone marrow biopsy reveals both acute myeloid leukemia and follicular lymphoma? See Discussion. Bone marrow biopsy reveals acute myeloid leukemia and follicular lymphoma. There were no other studies done, no chemo given, and the patient expired shortly after diagnosis. Should the follicular lymphoma be coded to a primary site C779 [Lymph nodes, NOS]?

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

    Code the primary site to C421 [bone marrow]. Per Rule PH26, bone marrow is the primary site when lymphoma is present only in the bone marrow. All the available physical exams, scans, and other work-up must also be negative for lymph node, tissue, or organ involvement. When there is no additional workup beyond the bone marrow biopsy and that biopsy is positive, code the primary site to bone marrow in those situations as well.

    		20100096 Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a 9/30/10 biopsy diagnoses follicular lymphoma, grade 1 and the patient is subsequently diagnosed on a 10/11/10 biopsy with large B-cell lymphoma which is stated to be a transformation of the prior lymphoma?

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

    Per Rule M11, this case is to be accessioned as two primaries; follicular lymphoma, grade 1 [9695/3] and diffuse large B-cell lymphoma (DLBCL) [9680/3]. The case represents a chronic neoplasm (follicular lymphoma, grade) and an acute neoplasm (diffuse large B-cell lymphoma) diagnosed within 21 days of one another and there is documentation of two biopsies, one confirming the chronic disease and the other confirming the acute disease.
