20071116 | Behavior--Bladder: What behavior code is used for a TURB path specimen diagnosis of "non-invasive urothelial carcinoma, no muscle found, depth of invasion cannot be assessed" when the clinician stages the case as Ta? See Discussion. | The SEER site specific coding module for bladder says, "If the only surgery performed is a TURB and if it is documented that depth of invasion cannot be measured because there is no muscle in the specimen, code the behavior as malignant and not in situ." | Assign behavior code 2 [in situ] based on the physician's stage Ta. When no other information is available and the TNM designation is not available, use the instructions on page C-844 in Appendix C of the 2007 SEER manual as a default. |

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. |

20071115 | CS Tumor Size/CS Site Specific Factor--Breast: How do you code the CS Tumor size and SSF6 fields for a breast cancer described as "Paget disease with underlying intraductal carcinoma (4cm x 3.2cm)"? | 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.CS Tumor Size: Assign code 040 for tumor size and code SSF6 as 050 [Invasive and in situ components present, size of entire tumor coded in CS TS]. The size of the invasive component is not stated AND proportions of in situ and invasive are not known. |

20071051 | MP/H Rules/Multiple Primaries--Lung: Please clarify the multiple primary rule M6 and the explanatory note that states when there is a single tumor in each lung, they are to be reported as multiple primaries unless stated or proven to be metastasis. See Discussion. | Single tumor in left lung, single tumor in right lung. The rules take you to M6. Suppose the tumor in left lung is biopsied and there is a physician statement that right lung tumor is metastatic from left lung tumor. The note under M6 is "When there is a single tumor in each lung, abstract as multiple primaries unless stated or proven to be metastatic." In this case, is it a single primary or multiple primaries? | For cases diagnosed 2007 or later: When there is a single tumor in one lung and a single tumor in the other lung, apply rule M6 and abstract as multiple primaries. Use this rule whenever there is a single tumor in each lung, even when neither tumor is biopsied or resected.
This rule is unique to lung. Our physician advisors emphasized that it is very unlikely that a single tumor in one lung could be metastatic from a single tumor in the opposite lung. Therefore, the default is to abstract as multiple primaries.
The note at M6 means that there must be proof that one tumor is metastatic in order to abstract as a single primary. For example, a biopsy of the tumor proving that it is metastatic. An opinion or belief that one tumor is metastatic is not sufficient. In the absence of proof, use rule M6 and abstract as multiple primaries.
A list of MP/H clarifications will be available. This issue will be included on the list. |

20071028 | MP/H Rules--Lung: Why the term "nodule" is not included as an equivalent term along with tumor, mass, lesion and neoplasm in the 2007 lung multiple primary rules? | Answer revised July 2008 For cases diagnosed 2007 or later: For the purpose of applying the Lung MP/H rules, the word "Nodule" can be used interchageably with "Tumor," "Mass," "Lesion" and "Neoplasm." HOWEVER, this does NOT apply to casefinding or staging. This revision will be added to the next version of the MP/H rules. Sinq question 20071028 will be revised. |

20071053 | Grade, Differentiation: How is grade coded for cases using the FNCLCC (Federation Nationale des Centres de Lutte Contre Ie Cancer) system? See Discussion. | Is FNCLCC a recognized system in the United States? Tongue was the primary site for the case we saw that used FNCLCC. | Do not code the data item Grade based on the FNCLCC grade. You may record the FNCLCC grade in a text field. | 2007 |
|
20071105 | Multiple Primaries/Histology--Lymphoma/Leukemia: How many primaries and what histologies are coded when a path diagnosis for a cervical/neck mass demonstrates classical Hodgkin's lymphoma on a background of chronic lymphocytic leukemia? | For cases diagnosed prior to 1/1/2010:Hodgkin disease and chronic lymphocytic leukemia are separate primaries according to our current instructions. Abstract and code them separately.
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. |

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. |

20071056 | Reportability/Terminology--Prostate: Is the diagnosis of "atypical glands suspicious for adenocarcinoma" sufficient to report a prostate cancer if a note states that there is "insufficient atypia to establish a definitive diagnosis of malignancy"? See Discussion. | Date of report is July 2005. One positive specimen of 12. Specimen 6: Diagnosis = Prostate tissue with a small focus of atypical glands suspicious for adenocarcinoma. Note. There is insufficient cytologic and/or architectural atypia to establish a definitive diagnosis of malignancy. Negative basal cell staining with cytokeratin... in atypical glands is consistent with the diagnosis of suspicious for adenocarcinoma. In addition, the diagnosis is suppported by a positive staining for alpha-methyl COA racemase (P504S), a recently discovered marker that is preferentially expressed in prostate cancer... |
This case is reportable. The diagnosis states "suspicious for adenocarcinoma." "Suspicious for" is a reportable ambiguous term.
The additional stains supported this "suspicious" diagnosis. A more definitive diagnosis could not be made based on this specimen. |

20071061 | Histology--Melanoma: How is a "malignant melanoma arising in a melanocytic nevus" coded? | The histology code is 8720/3 [malignant melanoma, NOS]. There is no specific code for melanoma arising in melanocytic nevus. According to our pathologist consultant, this is likely because nevi are so common, melanoma arising in association with them is common and appears to have no bearing on prognosis or treatment. Most pathologists do not include the nevus in the diagnosis of melanoma, even when they see it. Code melanomas arising in melanocytic nevi to the appropriate melanoma code, probably 8720, 8721, or 8743 in most cases. |
