20071015 | CS Lymph Nodes/CS Mets at Dx--Melanoma: How are these fields coded if a sentinel lymph node biopsy reveals no malignancy but there is an aggregate of melanoma cells in the lumen of a large vein immediately adjacent to the lymph nodes? | This question was answered by the CoC:
Do not count this as regional metastatic disease since there is no evidence it is an established tumor. Stage this as a N0. |

20071130 | Reportability--Brain and CNS: Are schwannomas of the spinal cord reportable when they are intradural? See Discussion. | The CNS guidelines basically indicate that schwannomas must all come from peripheral nerves and thus are not reportable when they are on the spinal cord. However, the COC Inquiry 18174 & 18068 states that schwannomas occasionally will develop inside the dura (intradural) on the spinal cord and would be reportable. | According to an expert consultant, schwannomas must be derived from Schwann cells which are not a part of the CNS. All schwannomas come from peripheral nerves. Benign and borderline tumors of the peripheral nerves (C47_), including peripheral nerves along the spinal cord, are not reportable. Please see http://www.cdc.gov/cancer/npcr/training/index.htm for more information. |

20071081 | CS Site Specific Factor--Lymphoma: Can the registrar calculate the International Prognostic Index (IPI) score from information found in the H&P or on the back of a TNM form for the SSF 3 field if the physician does not document it in the medical record? | This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Record the IPI score in SSF3 when the score is documented in the medical record. If the score is not stated, do not calculate it. |

20071096 | Multiplicity Counter--Prostate: How is multiplicity counter to be coded for a clinically inapparent prostate cancer for which sextant needle biopsy cores on left and right sides are positive for adenocarcinoma? See Discussion. | Prostate cancer typically presents as multifocal diffuse disease. The coding exercise in the MPH rules presentations coded prostate cancer as one tumor. Reference: SEER Training Web Casts - Other Sites Rules Practicum |
Code the number of tumors present if known. This information can be taken from any part of the record, including imaging and prostatectomy. If the only information available is "diffuse," or "multifocal," assign code 99. Do not assume there are multiple tumors just beacause there are multiple biopsies. When there is no information about the number of tumors, code Multiplicity Counter to 99 and Type of Multiple Tumors to 99. | 2007 |

20071008 | Histology (Pre-2007)--Breast: How is "invasive lobular carcinoma with signet ring cell features (95%) and ductal features (5%)" coded for a single tumor diagnosed prior to 2007? | For cases diagnosed 1/1/04-12/31/06, code histology to 8524 [Lobular mixed with other types of carcinoma]. Assuming there is no mention of in situ, Histology Coding Rule 3 applies: Use a mixed histology code if one exists
For cases diagnosed 2007-2014, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules. |

20071003 | MP/H Rules/Histology--Prostate: If a patient is stated to have prostate "cancer" but a pathology report is not available nor is a specific histology stated in the medical record, can this histology be coded to 8140 [adenocarcinoma] instead of 8000/3 [cancer] because the vast majority of prostate cancers are adenocarcinomas? | For cases diagnosed 2007 and later, the correct histology code is 8000/3 [cancer]. 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 Histology rules because no specific rules have been developed for prostate primaries.
To determine the histology, start at the SINGLE TUMOR: INVASIVE ONLY module, rule H8. The rules are intended to be reviewed in consecutive order within a module. Code the histology documented by the physician when there is no pathology/cytology specimen or the pathology/cytology report is not available. Code the histology as 8000/3 [cancer] because that is the only available information. In the absence of a pathology report or any other histologic confirmation, code the histology based on the information available. |

20071026 | MP/H Rules/Histology--Colon: When the microscopic description indicates a colon tumor is "tubulovillous," but the final diagnosis only states "adenocarcinoma," is the histology coded to 8263/3 [adenocarcinoma in a tubulovillous adenoma]? | For cases diagnosed 2007 or later: Yes. This is an example of a site-specific exception to the general rule to code only from the final diagnosis. The Colon Histology Rules specifically state that "other parts of the pathology report" may be used to identify a tumor arising from a polyp, adenomatous polyp, villous adenoma, or tubulovillous adenoma. |

20071022 | Reportability--Hematopoietic, NOS: If the bone marrow biopsy diagnosis is not reportable and cytogenetics studies indicate no clonal abnormality, is a case reportable if only the flow cytometry results show a "small monoclonal B-lymphocyte population consistent with a lymphoid component of a lymphoplasmacytic lymphoma or Waldenstrom macroglobulinemia"? See Discussion. | Bone marrow bx final diagnosis: Markedly hypercellular marrow consisting primarily of erythroid hyperplasia and, also, diffusely distributed small lymphocytes. Addendum comment: Flow cytometry demonstrated a small monoclonal B-lymphocyte population consistent with a lymphoid component of a lymphoplasmacytic lymphoma or Waldenstrom's Macroglobulinemia. Addendum comment: Cytogenetic analysis states no clonal abnormality was apparent. Normal female karyotype. Question 1: Is this case reportable, and if so, what histology? Question 2: Is there a hierarchy when flow cytometry and cytogenetics are done, but do not agree? |
For cases diagnosed prior to 1/1/2010:This case is not reportable at this point. A lymphoid component is not equivalent to a diagnosis of a reportable disease. In order to be a malignant, reportable disease, the condition must be monoclonal and irreversible. Cytogenetics were negative for malignancy (i.e. no monoclonal abnormality identified which is the criteria used to establish this diagnosis). Use all information available when determining reportability. 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. |

20071111 | MP/H Rules/Histology--Lung: How many primaries should be abstracted when a patient has an adenocarcinoma with bronchioalveolar-like features in the right upper lobe, adenocarcinoma in the right middle lobe and non-small cell carcinoma with clear cell features in the right lower lobe? See Discussion. | A RUL lung wedge resection and RML and RLL lobectomies were performed. The RUL resection showed invasive adenocarcinoma with bronchioalveolar-like features. Tumor size 9x.9x.8cm. The RLL lobectomy showed invasive non-small cell carcinoma with clear cell features. Tumor size 4.1x2.5x1.8cm. The RML lobectomy showed invasive adenocarcinoma. Tumor size 3.0x1.6x2.2cm. Comment: Essentially three invasive tumors and a focus of bronchioalveolar carcinoma were identified in 3 specimens. All of the tumors appear somewhat histologically different. The larger tumors in the right upper and middle lobe were somewhat similar but still appear histologically different and therefore the pathologic staging is done based on all tumors being separate. The pathologic staging for this case is pT2(4) pN0 pMX. What histology code and what site code are to be used on each abstract? |
For cases diagnosed 2007 or later: Abstract two primaries:
First, determine the number of tumors. There are three separate tumors in right lung in the example above:
Because there are three tumors, begin with rule M3 in the Multiple Tumors module. Stop at rule M11, multiple primaries for the tumor in the RLL (8310) compared to the tumors in the RUL and RML (8140 and 8140).
Now evaluate the tumors in the RUL and RML using the multiple primary rules. Start at rule M3 and stop at rule M12, single primary. |

20071007 | MP/H Rules/Histology: In the absence of a tissue diagnosis, should the histology field be coded based on the findings of a suspicious cytology or a CT scan that clinically confirmed the diagnosis? See Discussion. | Cytology (brushings at ERCP) which are highly suspicious of adenocarcinoma. A CT of the abdomen performed the next day shows a mass, most likely Klatskin tumor. Can the histology be coded to Klatskin tumor [8162/3] based on the CT findings? | For cases diagnosed 2007 or later, code the histology to 8162/3 [Klatskin tumor] using the histology from the CT. This case is confirmed clinically based on the CT. It cannot be accessioned based on suspicious cytology.
Rule H8 in the 2007 Histology Coding Rules for Other Sites provides instructions for coding histology when the pathology report and cytology report are not available. |
