20130138 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if a 2010 diagnosis of a preleukemic condition is subsequently diagnosed in 2012 with a specific leukemia that is not listed as a transformation? See Discussion. |
10/02/10 bone marrow biopsy showed myelodysplastic syndrome, unclassified [9989/3]. 6/19/12 bone marrow biopsy showed chronic myelomonocytic leukemia (CMML-2) [9945/3]. CMML-2 is not listed as an acute neoplasm for MDS. Is this the same disease? Per the pre-2010 rules, this would be the same disease. The current Heme DB indicates these are separate primaries. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. This case should be accessioned as two primaries, myelodysplastic syndrome (MDS) [9989/3] diagnosed 10/2/10 and chronic myelomonocytic leukemia (CMML-2) [9945/3] diagnosed 6/19/12 per Rule M15. Per Rule M15, use the Multiple Primaries Calculator when rules M1-M14 do not apply. When myelodysplastic syndrome (MDS) became reportable, the rules in effect at that time resulted in MDS often being the only diagnosis reported when both MDS and a leukemia were diagnosed. Statistics for some leukemias were impacted. Now we report both the MDS and the leukemia for greater accuracy. SEER*Educate provides training on how to use the Heme Manual and DB.

20130118 | Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for a diagnosis of Langerhans cell histiocytosis with extensive bony metastatic disease and lymphadenopathy? See Discussion. | Patient was diagnosed with LCH on a biopsy of the right femur. Imaging showed extensive bony metastatic disease, extensive infiltrative perinephritis, encasement of both kidneys, renal hilar, retroperitoneal and periaortic lymphadenopathy. The right femur biopsy pathology report did not state this was metastatic. | 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] per Rule PH30.
This patient has widely metastatic disease. Per Rule PH30, one needs to reference the Heme DB to determine the primary site and histology for this case. Per the Abstractor Notes section, Langerhans cell histiocytosis arises in the bone and many times can involve multiple bones, along with other organs and lymph nodes. Although the right femur was biopsied, this does not prove that the primary site is the femur [C402] because the patient has what was described as extensive bony metastatic disease.

20130095 | Grade--Heme & Lymphoid Neoplasms: How is grade coded for acute lymphoblastic leukemia, NOS? See Discussion. | The Heme DB indicates histology code 9811/3 [B lymphoblastic leukemia/lymphoma] is the current histology code to use for the now obsolete term of acute lymphoblastic leukemia [9835/3]. The Heme DB entry for histology code 9835/3 states to "Code grade specified by pathologist. If no grade specified, code 9." The Heme DB entry for the current histology code, 9811/3, states to code the grade to 6 [B-cell]. Should grade be coded to 6 [B-cell] for all cases coded to histology code 9811/3? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the grade to 6 [B-cell] for all cases of 9811/3 [B lymphoblastic leukemia/lymphoma] per Rule G3 in the Heme Manual.
Acute lymphoblastic leukemia, NOS [9835/3] is an obsolete code and cannot be used for cases diagnosed 2010 and later. The Heme DB indicates the correct histology code is 9811/3 and grade 6 [B-cell] for cases diagnosed 2010 and later.
For cases of acute lymphoblastic lymphoma, NOS [9835/3] diagnosed prior to 2010, use the pathology report information to code the grade. Code the grade as 9 [unknown] if the pathology report does not specify the grade.

20130170 | MP/H Rules/Histology--Breast: What is the histology code for "invasive carcinoma of the breast, no special type" as the final diagnosis on a pathology report? See Discussion. |
Recently pathology reports for breast primaries are no longer listing invasive ductal carcinoma as the histology on many cases if the treating physician calls the cancer an invasive ductal carcinoma. The pathology report (final diagnosis and synopsis) state this is invasive carcinoma, no special type.
Upon inquiry to the pathology department, the response received stated, In 2012, the WHO got rid of ductal carcinoma as a specific type. So what would have been called Invasive ductal carcinoma, Not Otherwise Specified (NOS), is now being called Invasive carcinoma, No Special Type (NST). In the new WHO classification, lobular, tubular, cribriform, mucinous, etc. are the special types. But ductal is gone.
Is this a change in terminology? Should these cases be coded as 8500/3 [ductal carcinoma, NOS] or 8010/3 [carcinoma, NOS]? |
Code the histology to ductal carcinoma, NOS [8500/3] for a pathology report with a final diagnosis of "invasive carcinoma, no special type." Do not code the histology to carcinoma, NOS [8010/3].
The 4th Edition of the WHO Classification of Tumors of the Breast refers to invasive ductal carcinoma as invasive carcinoma, no special type. The ICD-O-3 code remains the same as invasive duct carcinoma [8500/3]. The next revision to the MP/H Solid Tumor Rules will clarify this issue. |

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].

20130107 | Histology--Heme & Lymphoid Neoplasms: How is the histology coded for a diagnosis of polycythemia vera with myeloproliferative syndrome? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the histology to 9950/3 [polycythemia vera], the more specific histology, per Rule PH29. Myeloproliferative syndrome is a non-specific (NOS) histology and polycythemia vera is a specific type of myeloproliferative disease.

20130003 | MP/H Rules/Histology--Head & Neck: How is the histology coded for a mammary analogue secretory carcinoma (MASC) of the parotid gland? See Discussion. |
There is no histology listed in the ICD-O-3 for a mammary analogue secretory carcinoma. The pathologist stated that, "MASC is a recently described salivary gland tumor type which, as the name implies, resembles secretory carcinoma of the breast." Should the histology be coded 8550/3 [acinar carcinoma] or 8502/3 [secretory carcinoma of breast]? |
Assign code 8502/3 [secretory carcinoma of breast]. Acinar carcinoma [8550/3] describes a very typical type of salivary gland tumor only. This histology code does not adequately capture the histology in this case which describes a secretory carcinoma that is similar to mammary cancer. Both of these elements are reflected in the histology code 8502/3 [secretory carcinoma of breast]. |

20130210 | 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. |

20130152 | Primary site/Histology--Brain and CNS: How is the primary site and histology coded for a 2013 diagnosis of squamous cell carcinoma arising in a dermoid cyst of the third ventricle? See Discussion. | Patient has a dermoid cyst of the third ventricle of the brain diagnosed in 1998. In 2013 the cyst was removed and was diagnosed as squamous cell carcinoma. An internet search revealed a journal article in the Journal or Neuro-Oncology that states, "Although rare, malignant transformation of intracranial epithelial cysts has a poor prognosis." The combination of site C715 [third ventricle, NOS] and histology 8070/3 [squamous cell carcinoma] fails SEER Edit IF 38_3: Primary site and Morphology Impossible. | According to the literature, intracranial squamous cell carcinoma is very rare with most cases arising from a preexisting benign epidermoid cyst. The combination of C71_ and 8070/3 should be allowed. We will submit a request to have this edit revised. | 2013 |
