20120049 | Reportability--Heme & Lymphoid Neoplasms: Is polycythemia vera secondary to volume depletion reportable? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Secondary polycythemia vera is not reportable. See Appendix F.
Primary polycythemia vera is a condition in which there is an overproduction of blood cells due to a neoplastic process. Secondary polycythemia vera is an over production of red blood cells caused by a co-morbidity, in this case, volume depletion.

20120057 | Reportability--Appendix: Is a low grade mucinous neoplasm of uncertain malignant potential with an in situ mucinous cystadenoma component reportable? See Discussion. | The patient was diagnosed with pseudomyxoma peritonei and the pathology report final diagnosis stated, "Low grade mucinous neoplasm, of uncertain malignant potential, involving a dilated appendix (5cm) with the following features: In situ mucinous cystadenoma component is identified, with low-grade cytology of neoplastic epithelium." Does the presence of an in situ component make this mucinous cystadenoma of the appendix reportable based on the ICD-O-3 matrix rule? | This diagnosis is not reportable. Cystadenoma is not reportable. The "in situ" description in this case does not make cystadenoma reportable.
According to our expert pathologist consultant, this is a "non-invasive, low grade, epithelial proliferation in an often cystic appendiceal tumor, 8480/1. If this has leaked or ruptured it can seed the peritoneal cavity causing pseudomyxoma peritonei." |

20120093 | MP/H Rules/Multiple primaries -- Ovary: How many primaries are to be accessioned and what rule applies when a patient has a serous carcinoma of the right ovary treated with neoadjuvant chemotherapy followed by a debulking surgery that revealed a serous tubal intraepithelial carcinoma of the left fallopian tube? | For cases diagnosed 2007 or later, accession two primaries, serous carcinoma of the right ovary and serous tubal intraepithelial carcinoma of the left fallopian tube based on the information provided.
The steps used to arrive at this decision are:
Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text) and go to the Other Sites MP rules because neither the ovary nor fallopian tube have site specific rules developed.
Start at the MULTIPLE TUMORS module, Rule M3. The rules are intended to be reviewed in consecutive order within a module. The patient has multiple tumors with ICD-O-3 topography codes that are different at the third character (Cxx) and therefore this case should be accessioned as a multiple primary.
It could be helpful to know the extent of involvement noted prior to neoadjuvant therapy and debulking surgery. For example, if the patient had widely metastatic disease throughout the entire pelvis prior to the initiation of treatment, the answer may have been different. |

20120058 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be accessioned when the patient is diagnosed with an acute neoplasm (diffuse large B-cell lymphoma) per a pathology report and is subsequently diagnosed clinically with a chronic neoplasm (chronic lymphocytic leukemia/small lymphocytic lymphoma) less than 21 days later? See Discussion. | The patient was diagnosed with an extranodal DLBCL on a biopsy of the stomach. A bone marrow biopsy performed 16 days later showed no DLBCL, but demonstrated an abnormal CD5-positive B-cell population that was subsequently referred to as CLL/SLL by the physician. The peripheral blood was negative and showed only moderate thrombocytopenia.
Does rule M10 apply in this case? Abstract the acute neoplasm as a single primary (DLBCL) as there was only one pathology specimen (stomach biopsy) proving DLBCL and the bone marrow did not definitively identify CLL/SLL. |
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 per Rule M11. Code the histology of one primary to 9680/3 [diffuse large B-cell lymphoma], the acute neoplasm. Code the histology for the second primary to 9823/3 [chronic lymphocytic leukemia/small lymphocytic lymphoma], the chronic neoplasm.
Per Rule M11, abstract as multiple primaries when both a chronic and acute neoplasm are diagnosed simultaneously or less than or equal to 21 days apart AND there is documentation of two pathology specimens, one confirming the chronic neoplasm (bone marrow biopsy) and one confirming the acute neoplasm (stomach biopsy).

20120004 | Grade--Heme & Lymphoid Neoplasms: How is grade coded for a malignant non-Hodgkin lymphoma, large B-cell type, with features consistent with T-cell rich variant? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code grade to 6 [B-cell] for the histology malignant non-Hodgkin lymphoma, large B-cell type, with features consistent with T-cell rich variant [9680/3]. Under the Definition section for histology code 9680/3 it states there are morphologic variants of the disease: centroblastic, immunoblastic, plasmablastic, T-cell/histiocyte-rich, anaplastic.
Rule G3 in the Heme Manual confirms the grade listed in the Heme DB under its Grade section for the histology 9680/3. While the patient presented with a variant of DLBCL that is T-cell/histiocyte rich, it is still a B-cell phenotype. The grade is coded accordingly.

20120062 | MP/H Rules/Multiple primaries--Breast: How many primaries are accessioned if a patient has a history of breast cancer in 2006 treated with bilateral mastectomies and in 2011 is found to have invasive carcinoma in "breast tissue, right lumpectomy"? See Discussion. |
Patient was originally diagnosed in June 2006, with right breast cancer and underwent lumpectomy and chemotherapy. This was followed by a bilateral mastectomy with reconstruction in January of 2007 that showed no residual tumor in the breast but 1 positive right axillary lymph node. The patient started Arimidex in May 2007 and had ongoing follow-up. In November 2011, the patient noted a "lump to her right upper reconstructed breast at approximately 2:00." Needle biopsy in December 2011 showed invasive carcinoma and the patient underwent a lumpectomy. The lumpectomy pathology report stated, "Breast tissue, right, lumpectomy: poorly differentiated infiltrating ductal cancer." There is no comparison of the current pathology to the previous pathology, as the previous lumpectomy/mastectomy was done at another facility. The patient is being treated at this facility with radiation as if this is a "recurrent/persistent right sided breast cancer." Should this case be classified as a new primary because the pathology report indicates the malignancy was in breast tissue? Or is this actually a chest wall recurrence given the fact that the patient was previously treated with bilateral mastectomies? Should this case be treated as indicated in SINQ 20110111? |
For cases diagnosed 2007 or later, accession two primaries, right breast cancer diagnosed in June 2006 and a subsequent right breast primary diagnosed in December 2011. The steps used to arrive at this decision are: Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Breast MP rules because site specific rules exist for this primary. Start at the MULTIPLE TUMORS module, rule M4. The rules are intended to be reviewed in consecutive order within a module. Accession two primaries, tumors diagnosed more than five (5) years apart are multiple primaries. If the pathology report stated the tumor originated in residual breast tissue, then this is a new tumor and, therefore, a new primary per rule M5. If the pathology report stated the tumor arose in the chest wall and/or there is no designation of residual breast tissue, then this is a regional metastasis and not a new primary. |

20120012 | Histology--Heme & Lymphoid Neoplasms: How is histology coded if the pathology report shows diffuse large B-cell lymphoma arising in a small cell lymphoma - Richter's transformation, also compatible with chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL)? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the histology to 9680/3 [diffuse large B-cell lymphoma (DLBCL)].
For CLL (and CLL/SLL), Richter's transformation represents when CLL changes into DLBCL. In this case, there was a biopsy that demonstrated a diagnosis of the chronic disease (CLL/SLL) transforming (Richter's transformation) into an acute disease DLBCL.
Per Rule M8, one is instructed to abstract the acute neoplasm as a single primary when both a chronic (CLL/SLL) and an acute neoplasm (diffuse large B-cell lymphoma (DLBCL)) are diagnosed simultaneously there is documentation of only one positive bone marrow biopsy, lymph node biopsy or tissue biopsy.

20120051 | MP/H Rules/Histology--Breast: What histology code for a diagnosis of pleomorphic lobular carcinoma in situ? | For cases diagnosed 2007 or later, code the histology as lobular carcinoma, in situ [8520/2].
The steps used to arrive at this decision are:
Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Breast Histo rules because site specific rules exist for this primary.
Start at the SINGLE TUMOR: IN SITU CARCINOMA ONLY module, Rule H1. The rules are intended to be reviewed in consecutive order. Stop at the first rule that applies to the case you are processing. Code the histology to lobular carcinoma in situ [8520/2] because this is the only histologic type identified.
Pleomorphic lobular carcinoma is a variant of lobular carcinoma which does not have an ICD-O-3 code. It is still a lobular carcinoma. The identification of the variants of lobular carcinoma was a relatively recent discovery and the information was not available when the 2007 MP/H Rules were written. All of the lobular variants will be included in the next revision of the MP/H Rules. |

20120067 | MP/H Rules/Histology--Thyroid: How is the histology coded for a poorly differentiated thyroid carcinoma with rhabdoid phenotype arising in a papillary carcinoma? | For cases diagnosed 2007 or later, code the histology as papillary carcinoma, poorly differentiated [8260/33].
The WHO classification lists grade III papillary carcinoma as one of the synonyms for poorly differentiated thyroid carcinoma.
The steps used to arrive at this decision are: Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Other Sites Histo rules because site specific rules have not been developed for this primary. Start with the SINGLE TUMOR: INVASIVE ONLY module, rule H8. The rules are intended to be reviewed in consecutive order within a module. Per rule H13 "phenotype" is not a term used to code a more specific histology. Moving to Rule H14 the histology is coded 8260/3 [papillary adenocarcinoma]. |

20120013 | Reportability--Heme & Lymphoid Neoplasms: Should a 2011 diagnosis of Langerhans cell histiocytosis be accessioned as a reportable case if the patient had a disease free interval between the 2011 diagnosis and when the patient was initially diagnosed with Langerhans cell histiocytosis prior to 2010? See Discussion. |
The patient was diagnosed with Langerhans cell histiocytosis as a child when the disease was not reportable [9751/1]. The patient was disease free until a recurrence in 2011. Langerhans cell histiocytosis is reportable if diagnosed 1/1/2010 and later [9751/3]. The Heme Manual states this is a single primary, but the behavior has changed from borderline to malignant since the initial diagnosis. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. Do not accession the 2011 diagnosis of Langerhans cell histiocytosis. In the Abstractor Notes section of the Heme DB is indicates this is reportable for cases diagnosed 2010 and later. However, this patient was initially diagnosed prior to 2010 when it was not a reportable disease process. The histology code for Langerhans cell histiocytosis has not changed over time. The histology code for cases of Langerhans cell histiocytosis diagnosed prior to 2010 was also 9751 per the ICD-O-3. The only change since 2010 was in the behavior code for this disease. It changed from borderline [/1] to malignant [/3]. The current disease represents a recurrence of the previous Langerhans cell histiocytosis. Per the Multiple Primary rules, Rule M2, a single histology is a single primary. The original diagnosis was made before the disease was reportable; do not report the disease recurrence or progression as a new primary.
