20130192 | MP/H Rules/Histology--Pleura: How is histology coded when the pathology report final diagnosis is "malignant neoplasm, compatible with malignant mesothelioma" if the COMMENT section of the pathology report indicates the tumor has a mixed epithelial and sarcomatoid pattern? See Discussion. | This case was discussed with a pathologist who feels the correct histology should be biphasic mesothelioma (9053/3) because there are both epithelial and sarcomatoid components to this tumor. However, applying the current MP/H Rules, the histology is coded to 9050/3 (mesothelioma, NOS) because the term "pattern" cannot be used to code a more specific histologic type for invasive tumors. If this truly is a biphasic mesothelioma, that data is lost for researchers because the current MP/H Rules fail to capture this information. Should the term pattern be used to code the more specific histology in this case? | Code the histology to malignant mesothelioma, NOS [9050/3]. Apply the MP/H Rules as written until they are revised. The word "pattern" and other terms will be reconsidered for the next iteration of the rules. | 2013 |

20130114 | Histology--Heme & Lymphoid Neoplasms: How is the histology coded when the bone marrow biopsy shows acute myeloid leukemia, but the physician states this is therapy-related AML secondary to prior radiation treatment? See Discussion. | Physician states this patient has radiation therapy-related AML due to radiation received as treatment for a prior prostate cancer. The bone marrow and other immunophenotyping do not state this is therapy-related AML. Should the histology be coded AML, NOS [9861/3] or therapy-related AML [9920/3]? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the histology as therapy-related acute myeloid leukemia, NOS [9920/3] when the physician states this is a therapy-related AML.
The therapy-related diagnosis may be either clinically or pathologically stated to code the histology to 9920/3. In this case, the physician is aware of the previous chemotherapy, hormone therapy or radiation and adds that knowledge to the histologic findings of AML. The pathology report did not include this clinical, historical information as part of the final diagnosis. However, one can code therapy-related acute myeloid leukemia because clinically it was stated.
We recommend that you clearly document in the abstract that you are coding a clinical histology.

20130019 | Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded when a patient has a lymph node biopsy and peripheral blood that are positive for B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma but refuses a bone marrow biopsy? | 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 PH5. Note 1 for Rule PH5 states CLL always has peripheral blood involvement. If the peripheral blood is positive for CLL/SLL and no bone marrow biopsy is done, code the primary site to C421 [bone marrow].

20130182 | Primary site--Head and Neck: How is primary site coded if a floor of mouth biopsy reveals microinvasive squamous cell carcinoma but the definitive resection of the tongue and floor of mouth unifocal lesion reveals only in situ squamous cell cancer? See Discussion. | Patient with overlapping lesion of tongue and floor of mouth. Initial biopsy of floor of mouth reveals microinvasive squamous cell cancer. Definitive resection reveals in situ squamous cell cancer. Pathology report states unifocal tumor. The tumor site on pathology report is documented as involving the tongue and floor of mouth.
Should the primary site be coded to floor of mouth because it is the site of invasive disease? Or is primary site C148 [overlapping sites of lip, oral cavity and pharynx] because invasion should not be used to determine primary site? |
Code the primary site to C068 [overlapping lesion of other and unspecified parts of the mouth]. Based on the information provided, this is a tumor described as a "book-leaf" lesion a lesion that overlaps the floor of the mouth and the underside of the tongue. | 2013 |

20130031 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a plasmacytoma of the intervertebral disc is diagnosed in 2010 followed by a diagnosis of immature plasma cell myeloma by a right hip biopsy in 2011? See Discussion. |
The patient was diagnosed with intervertebral disc plasmacytoma and had radiation therapy to the pelvic bones in 2010. In 2011 (more than 21 days later) a right hip biopsy revealed immature plasma cell myeloma. There is clinical documentation that this is progression into myeloma. Per the Heme DB (Primary Site(s) and Definition sections) and Rule PH30, in the Heme Manual, the primary site is coded to C421 [bone marrow] and the histology is coded 9732/3 [plasma cell myeloma] when there is a clinical diagnosis of multiple myeloma and/or there is no documentation of a bone marrow biopsy or the results are unknown. This patient did have a bone marrow biopsy that indicates there are an increased plasma cells present; plasma cells represent less than 10%. The skeletal survey and bone scan did not reveal any further lesions. Is this progression of disease because there is only one lesion in the right hip 8 months after the diagnosis of plasmacytoma? Or is this a second primary based on the right hip biopsy that showed plasma cell myeloma and the physician's documentation of disease progression? Plasmacytomas are usually single lesions. Would this disease process have multiple lesions if they are diagnosed at different times? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. This case is accessioned as two primaries: Plasmacytoma diagnosed in 2010 and plasma cell myeloma diagnosed in 2011 per Rule M10. The patient has a diagnosis of a solitary plasmacytoma (chronic neoplasm) followed by a diagnosis of plasma cell myeloma (acute neoplasm) diagnosed greater than 21 days later. The physician is calling this a progression to plasma cell myeloma even though the bone marrow has less than 10% plasma cells, take this statement as progression or a clinical diagnosis of plasma cell myeloma.

20130068 | Reportability--Heme & Lymphoid Neoplasms: Is polycythemia, NOS reportable? See Discussion. | The physician states the patient has polycythemia. There is no confirmation of primary polycythemia nor is there mention of polycythemia vera. JAK2 was negative. | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Polycythemia, NOS is not reportable. Polycythemia, NOS is not a synonym for polycythemia vera and, therefore, is not reportable. To be reportable the diagnosis must be polycythemia vera, or one of the other terms listed in the Alternate Names section of the Heme DB.
Polycythemia (also known as erythrocytosis) is a disease state in which the proportion of blood volume that is occupied by red blood cells increases. Blood volume proportions can be measured as a hematocrit level. It can be due to an increase in the mass of red blood cells ("absolute polycythemia"); or to a decrease in the volume of plasma ("relative polycythemia").

20130078 | Ambiguous terminology/Reportability--Heme & Lymphoid Neoplasms: Is a physician diagnosis of "appears to be a myeloproliferative disorder" reportable if the patient has no treatment and the physician elects to follow the patient with CBC's?. |
Yes. This is a reportable diagnosis and should be accessioned with the histology coded to 9975/3 [myelodysplastic/myeloproliferative neoplasm, unclassifiable]. The word is a reportable ambiguous term per the Hematopoietic Coding Manual (Case Reportability Instructions, Rule 4). Myeloproliferative disorder is synonymous with myeloproliferative disease. Myeloproliferative disease is listed as an alternate name for myelodysplastic/myeloproliferative neoplasm, unclassifiable. |

20130093 | MP/H Rules/Histology--Lung: What histology code is used for an adenocarcinoma in situ/bronchioloalveolar carcinoma (BAC) of the lung? See Discussion. | Classification of lung malignancies has undergone a change. The bronchioloalveolar carcinoma histology is being replaced by adenocarcinoma in situ and minimally invasive adenocarcinoma, using an evaluation of lepidic growth pattern in the tumor.
The final diagnosis is "adenocarcinoma in situ/BAC" and the comment states, "The findings in the current biopsy are most compatible with low grade malignant lesions which, in this sample, shows features of adenocarcinoma in situ (former bronchioloalveolar adenocarcinoma), given the proliferation of pneumocytes is limited to the alveolar lining with no evidence of invasion. However, classification of the lesion depends, per reference guidelines (Travis et al. J THOR ONCOL 2011 6,(2):244-275), on its size and its overall histologic features, to rule out the presence of an invasive component and therefore can only be performed upon examination of it in its entirety, upon resection." The radiation oncologist staged this T1N0M0, stage 1 BAC. |
Code the histology to 8140/2 [adenocarcinoma in situ, NOS].
The comment for this case is consistent with information from the CAP protocol, which says, "The diagnosis of bronchioloalveolar carcinoma requires exclusion of stromal, vascular, and pleural invasiona requirement that demands the tumor be evaluated histologically in its entirety. It is therefore recommended that a definitive diagnosis of bronchioloalveolar adenocarcinoma not be made on specimens in which the tumor is incompletely represented."
This tumor was not completely resected. Therefore, code to adenocarcinoma in situ based on the information provided. |

20130094 | MP/H Rules/Multiple primaries--Lung: How many primaries are accessioned and which M rule applies for a 2010 diagnosis of clear cell adenocarcinoma of the left upper lobe lung followed by a 2012 diagnosis of adenosquamous carcinoma of lung origin without evidence of a primary lung tumor? See Discussion. | Patient was diagnosed with T1 N0 M0 adenocarcinoma with prominent clear cell features [8310/3] in the LUL on 08/05/2010. The patient underwent a lobectomy only.
On 10/09/2012 the patient underwent an iliac bone biopsy showing non-small cell carcinoma with glandular and squamous features [8560/3]. Clinically, the physician is calling this stage IV adenosquamous carcinoma of lung origin involving lymph nodes, spleen and bones. There were no FDG avid pulmonary nodules found. There was no pathologic comparison to the prior lung tumor.
Should the 2012 diagnosis be a new primary because the histology is different from the 2010 diagnosis? Or should this be one primary because there appears to be only metastatic disease with no new primary lung tumor identified in 2012? The choice of one primary seems supported by the fact that the 2012 tumor showed glandular and squamous features, and the 2010 tumor also showed glandular and clear cell (NOS) features. The clear cell could have been a clear cell squamous cell carcinoma. The original tumor was not re-examined. |
Accession a single primary, clear cell adenocarcinoma [8310/3] of the left upper lobe lung [C341] diagnosed on 08/05/2010.
The MP/H Rules do not apply to the 2012 diagnosis because only metastatic sites were examined and there was no re-examination of the original 2010 tumor. Therefore, the disease process in 2012 is assumed to be metastatic from the lung primary diagnosed in 2010. |
