20091003 | MP/H Rules/Histology--Peritoneal primary: Can the cell types from the primary site and a metastatic site be combined to code histology? See Discussion. | Patient has vaginal mass biopsy diagnosed as 'papillary carcinoma with psammoma bodies.' Two weeks later the patient has laparoscopy with multiple peritoneal biopsies, diagnosed as 'well differentiated serous adenocarcinoma'. Patient stated to have peritoneal primary with mets to vagina and was treated with chemotherapy. Do we code the histology to 8441/31 from the primary site biopsies, or can we use 8460/3, combining the cell types from the primary and metastatic sites? Please see SINQ 20041062 for a similar question before the 2007 MP/H rules. | For cases diagnosed 2007 or later, assign code 8441 [serous adenocarcinoma, NOS]. Code the histology from the primary site when available. Do not combine histologies from primary and metastatic sites. In this primary peritoneal case, the diagnosis from the peritoneal biopsies was serous adenocarcinoma. |

20041050 | Surgery of Primary Site--Rectum: How do you code a procedure described as a "transanal resection, debulking of a large rectal mass"? See Discussion. | Patient is not a surgical candidate due to "other medical conditions". Colonoscopy done for anemia and rectal bleeding. At the colonoscopy a "Transanal Resection Debulking of large rectal mass" is performed. Two specimens are sent to the lab. The first is labeled "rectal mass" and is a 2.0 cm diameter spherical fragment of tissue. The second is labeled "transanal debulking rectal mass" and is described as multiple, irregular shaped fragments of tan, rubbery tissue measuring 5.0 x 5.0 x 3.0 cm. Final path diagnosis: Debulking of rectal mass: Adenocarcinoma greater than 2 cm in size, resection margins positive for tumor. | For cases diagnosed 1998-2002, code Surgery of Primary Site to 20 [Local tumor excision, NOS]. Because the procedure was performed via colonoscopy and apparently did not involve proctectomy, the best choice is a local excision. | 2004 |

20081121 | Multiple primaries/Histology--Lymphoma: How many primaries should be abstracted and how should the histology field(s) be coded in this situation? How would the bone marrow involvement by only NHL be handled? Composite lymphoma (9596) as defined by SEER and ICD-O is NHL and HD in one node which fits the final impression on the removed cervical node. See Discussion. |
Patient presented with cervical, supraclavicular & superior mediastinal lymphadenopathy. A cervical node was excised for pathological review. The final impression on that node was Composite lymphoma characterized by (1) Nodular Lymphocyte Predominant Hodgkin Lymphoma [HD] (2) CLL/SLL [NHL]. Then, a bone marrow aspirate/bx was performed revealing CLL/SLL [NHL]. | For cases diagnosed prior to 1/1/2010:This is a single primary. The histology code is 9596/3 [composite Hodgkin and non-Hodgkin lymphoma]. According to the Single Versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table, 9596/3 followed by 9670/3 is one primary. For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ. |

20091066 | Multiplicity Counter--Lung: How is this field coded when there is no evidence of the primary tumor? See Discussion. | Patient presented with large mediastinal mass. CT showed no intraparenchymal lung tumor. Biopsy of mediastinal mass revealed adenocarcinoma consistent with lung primary. | Code Multiplicity Counter to code 99 [Unknown]. | 2009 |

20120073 | Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for a 2011 diagnosis of systemic mastocytosis? See Discusson. | Patient presented with leukopenia, anemia and monoclonal gammopathy. A bone marrow biopsy in 2011 showed systemic mastocytosis [9741/3]. A subsequent shave biopsy of abdominal skin showed histologic features that were consistent with a diagnosis of mastocytosis. A later bone marrow biopsy was subsequently performed that showed progressive systemic mastocytosis. | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per Rule PH30, use the Heme DB to determine the primary site and histology when rules PH1-PH29 do not apply. The Heme DB indicates the primary site for systemic mastocytosis is always coded to C421 [bone marrow].

20031198 | Surgery of Primary Site/Date Therapy Initiated--Head & Neck: Would a biopsy, NOS, that removed the majority of the tumor be used to code these fields? See Description. | Patient underwent biopsy, NOS, of a carcinoma of the tongue. Subsequent glossectomy revealed microscopic focus of residual squamous cell carcinoma. | If the biopsy NOS removed all macroscopic disease, code the date of the biopsy NOS as the date therapy initiated. If macroscopic disease remained following the biopsy NOS, code the glossectomy date as the date therapy initiated. | 2003 |

|
20091114 | MP/H Rules/Multiple primaries--Breast: Would a left chest wall mass excision stated to be ductal carcinoma consistent with a breast primary and, "compatible with either local recurrence or potentially a metastasis" be a new primary per the MP/H rules? See Discussion. | Patient underwent mastectomy in 1986 for infiltrating ductal carcinoma of left breast. Excision of left chest wall mass in March 2009 showed ductal carcinoma consistent with breast primary. The pathology report COMMENT stated it would be compatible with either local recurrence or a metastasis. The patient's primary breast carcinoma material is not available for direct comparison and the MP/H rules instruct us to ignore metastasis. | For cases diagnosed 2007 or later, the MP/H rules do not apply to metastasis. If there is no further information available for this case, the MP/H rules do not apply to the 2009 diagnosis. | 2009 |

|
20031195 | EOD-Clinical Extension--Prostate: Is this field coded to 15 [Tumor identified by needle biopsy for elevated PSA] when it is unknown whether or not a TRUS was done? See Description. | Patient was admitted for radiation therapy for prostate cancer. H&P states that patient had elevated PSA. PE showed benign feeling prostate. Stage is clinical T1c. There is no mention of whether or not TRUS had been done. | For cases diagnosed 1998-2003: EOD extension code 15 is correct for this case example. When there is no other documentation available, the AJCC stage may be used to determine extension. | 2003 |
|
|
20031206 | EOD-Extension: How is this field coded for synchronous primaries when metastatic disease is found and there is no statement to indicate which primary is the source of the metastases? See Description. | Patient was diagnosed with both esophageal and pancreatic cancer. Liver metastases were also identified. The source of the liver mets is unknown. | For cases diagnosed 1998-2003: Search the record for information about the source of the metastasis. If no such information can be found, code the metastasis to both primaries. Update the abstracts when information becomes available confirming the primary site responsible for the metastasis. Assuming the liver metastases in the example above are distant (i.e. not contiguous) code extension as 85 [Metastasis]. | 2003 |

20100048 | Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for a patient diagnosed with Langerhans cell histocytosis/eosinophilic granuloma involving both the seventh rib and the right temporal bone? See Discussion. | Patient was diagnosed with Langerhans cell histiocytosis/eosinophilic granuloma following a biopsy of the seventh rib on 3/22/10. On 4/13/10 the patient had a right external ear canal mass (right temporal bone) biopsy with same diagnosis. Should the primary site be coded to bone, NOS [C419]? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per Rule PH30, use the Heme DB to determine the primary and code it to bone, NOS [C419]. Langerhans cell histiocytosis can occur as a solitary lesion, multifocal lesions, or multisystem disease. In this case, the patient has multifocal disease of the bone. The abstractor notes in the Hematopoietic DB were used as a reference for this answer.
