20021197 | Scope of Regional Lymph Node Surgery--Breast: How should this field be coded when a mastectomy that removed 3 sentinel lymph nodes is later followed by an axillary lymph node dissection that removed 17 lymph nodes? Should all of the lymph node information be coded to this field, even though the Number of Regional Lymph Nodes Examined field will be coded to the number of lymph nodes from the most definitive surgery (17)? | For cases diagnosed 1/1/2003 and after: Yes, all of the lymph node information should be coded to the Scope of Regional Lymph Node Surgery field using code 7 [Sentinel node biopsy and code 3, 4, or 5 at different times].
The Number of Regional Lymph Nodes Examined field no longer exists for this time frame. |

20020003 | EOD-Size of Primary Tumor: Can you code the tumor size if you have the aggregate size given for two or more tumor masses? | For cases diagnosed 1998-2003:
No. Never code the aggregate size in the Size of Primary Tumor field when the pieces removed come from TWO OR MORE tumors. If there is a clinical statement regarding the size of two or more tumors, code this field to the size of the largest tumor.
The aggregate size can only be used to code the Size of Primary Tumor field when the PATHOLOGIST estimates the size of the tumor from the pieces of ONE tumor removed by the surgeon. |

20021041 | First Course of Cancer-Directed Therapy--All Sites: How do we code retinoic acid? | The code for retinoic acid depends upon the primary site and histology of the tumor. Code retinoic acid (also called Vitamin A, tretinoin, ATRA, all-transretinoic acid or Vesanoid) in the Immunotherapy field as 01 [Immuno administered as first course therapy] for acute promyelocytic leukemia. This drug is given to patients as an alternative to chemotherapy.
For all other sites/histologies, code retinoic acid in the Other Cancer-Directed Therapy Field. Use code 2 [Other experimental cancer-directed therapy] or 3 [Double-blind clinical trial, code not yet broken] if the drug is given as part of a protocol. If the drug is not being given as part of a protocol or you don't know whether it is part of a protocol, use code 1 [Other cancer-directed therapy]. |

20020069 | Reportability--Hematopoietic, NOS: Is "evolving" multiple myeloma reportable to SEER? | For cases diagnosed prior to 1/1/2010:No, it is not SEER reportable. The diagnosis of "evolving" multiple myeloma could represent a plasmacytoma, plasma cell dyscrasia or another lymphoproliferative disorder. Some of these histologies are SEER reportable, but some are not. Additional information would be needed to determine reportability. If you are unable to obtain more information, the case is non-reportable.
For cases diagnosed 2010 forward, 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. |

20021124 | Multiple Primaries (Pre-2007)/Primary Site/EOD-Extension--Lung: Should lung cases be counted as more than one primary when nodules removed from separate lobes of the same lung have either the same histology or they are different immunophenotypes of the same main histologic classification (e.g., adenocarcinoma)? See discussion. |
1. Path report: "Two nodules (RLL, RUL) of primary pulmonary demonstrate adenocarcinoma with different histologic appearances and different immunophenotypes consistent with synchronous lung adenocarcinomas." Per ICC interpretation, two lung primaries are favored. 2. Path report: "Two peripheral nodules (LLL, LUL) demonstrate similar P.D. non-small cell carcinoma with features of large cell undifferentiated carcinoma." |
For tumors diagnosed prior to 2007: According to current SEER rules, both examples represent one primary because both tumors are in one lung and of a single histologic type. Code the Primary Site field to C34.9 [Lung, NOS] for both examples and the EOD-Extension field to 77 [Separate tumor nodules in different lobe]. This will capture the fact that there are multiple tumors within the lung for each of these examples. Differences in immunophenotypes confirm independent de novo cancers and rule out metastasis. Immunophenotype differences do not equate to different histologies. In the first example described, there are different histologic features; however, the main classification is adenocarcinoma. For tumors diagnosed 2007 or later, 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. |

20021101 | Histology (Pre-2007)/Grade, Differentiation--All Sites: How do we code these fields for a tumor that is predominantly a "well differentiated liposarcoma" [8851/31] that has a less predominent type of "dedifferentiated liposarcoma" [8858/33]? If we code the predominant cell type [8851/3] and the worst grade [3], the case will not pass edits because well-differentiated liposarcoma requires a differentiation code of 1. See discussion. | Example: Dedifferentiated liposarcoma, with the following features: size 22 cm, FNCLCC grade 3 of 3 [high grade]. Path comment: The tumor consists of predominantly well-differentiated sclerosing subtype liposarcoma and areas of high grade spindle cell (non-lipogenic) sarcoma. The area of high grade spindle cell sarcoma measured up to 7.5 cm. | For tumors diagnosed prior to 2007:
Code the Histology field to 8858/33 [Dedifferentiated liposarcoma, grade 3]. The pathologist gives a final designation of Dedifferentiated liposarcoma and then provides further details in the comment that do not negate the final designation.
Grade is usually coded independent of the cell type. There are a few Catch-22 situations, like this one, in which the grade is built into the name of the cell type.
For tumors diagnosed 2007 or later, 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. |

20021188 | Multiple Primaries (Pre-2007)--Testis: How many primaries should be reported when seminoma is diagnosed simultaneously in both testicles and both tumors are encapsulated? | For tumors diagnosed prior to 2007:
Report this cases as two primaries, unless there is information in the record confirming one primary.
For tumors diagnosed 2007 or later, 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. |

20021168 | Histology (Pre-2007)--Corpus Uteri: What code is used to represent the histology "endometrioid carcinoma with squamous differentiation" for an endometrium primary? | For cases diagnosed 2004-2006:
Endometrioid adenocarcinoma with squamous differentiation is coded 8570 [Adenocarcinoma with squamous metaplasia].
For tumors diagnosed 2007 or later, 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. |

20021194 | Grade/Histology (Pre-2007)--All Sites: What code is used to represent these fields for the histology "High grade dysplasia (adenocarcinoma in situ)" or "AIN III/High grade AIN"? |
For tumors diagnosed prior to 2007: Code the Histology field for the first example to 8140/2 [Adenocarcinoma, NOS, in situ] and for the second example to 8077/2 [AIN, grade III]. For both of the cases code the Grade, Differentiation field to 9 [Cell type not determined not stated or not applicable]. The 6th digit (grade code) of ICD-O-3 describes how much or how little a malignant tumor resembles the normal tissue from which it arose. In contrast, "grade" is used in the examples above to describe the degree of dysplasia, from mild dysplasia (low grade) to severe dysplasia (high grade). Do not record the degree of dysplasia in the 6th digit grade field. For tumors diagnosed 2007 or later, refer to the MP/H rules for histology coding instructions. 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. |

20021202 | Primary Site--Head & Neck (Middle ear): How do you code site for a skull based tumor consistent with a low grade papillary adenocarcinoma of "endolymphatic sac origin"? | Code Primary Site to C30.1 [Middle ear]. The endolymphatic sac is part of the inner ear labyrinth located with in the petrous portion of the temporal bone. | 2002 |
