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. |

20021189 | Multiple Primaries--Lymphoma: How many primaries should be reported when a 5/99 diagnosis of stage III follicular large cell lymphoma [9698/3] of the conjunctiva [C69.0] is followed with a 6/01 diagnosis of small cleaved lymphoma [9591/3] of the breast [C50.9]? See discussion. |
The Lymphatic and Hematopoietic Diseases folding table states that this should be one primary, but is this true when they are both extralymphatic in origin? |
For cases diagnosed prior to 1/1/2010:Report as two primaries if that reflects the medical opinion for this case. The table is a guide, but does not overrule the clinician's opinion. These extranodal lymphomas are diagnosed in two different sites more than 2 months apart. They are listed as the same primary in the folding table because 9591/3 is generally a non-specific term and 9698/3 is a more specific cell type. If both histologies were diagnosed in the same organ or tissue, this is the same primary. However, the primary sites in this example are distinctly different. 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. |

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. |

20021003 | Multiple Primaries (Pre-2007): Whenever two hollow organs are diagnosed simultaneously with the same histology, one being invasive and the other in situ, can one assume that mucosal spread has occurred and that this situation represents one primary? In the absence of a physician statement, how do you determine mucosal spread from one organ to another? | For tumors diagnosed prior to 2007:
Yes, this type of situation represents one primary. A tumor that is breaking down can be invasive in the center with in situ cancer at the margins. Occasionally the in situ margin can move into a contiguous organ with the same type of epithelium.
Physicians may describe mucosal spread in various manners. You will see the terms "intramucosal extension," "in situ component extending to," or statements of an invasive component in one organ, with adjacent/associated in situ carcinoma in a contiguous organ with the same type of epithelium. A frequent example of this process is bladder cancer extending into the prostatic urethra via mucosal spread.
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. |

20021149 | EOD-Extension--Head & Neck: In the absence of a clear surgical or pathologic description of how the salivary gland involvement relates to the head and neck primary, do we code the involvement as direct extension, further extension or metastasis? See discussion. | A composite resection of tonsillar mass and a modified radical neck dissection is performed. According to the pathology report: Squamous cell carcinoma involvement of tonsil with invasion of skeletal muscle. A separate specimen labeled "tumor" indicates a salivary gland is also involved with tumor. Neck dissection: 1 lymph node with metastasis. | For cases diagnosed 1998-2003:
In the absence of a clear statement that the gland was involved by direct extension, code the EOD-Extension field to 85 [Metastasis]. In this case, the salivary gland tumor was described as a "separate specimen" that contained the salivary gland. The extension does not appear to be contiguous for this case.
If the salivary gland involvement had been by direct extension, which would be assumed if there had been contiguous involvement of the gland with the primary site, then code the EOD-Extension field to 80 [Further extension]. If there had been direct extension, the surgeon probably would not have dissected through the tumor. The resection specimens would have been contiguous. |

20021044 | Histology (Pre-2007)/Grade, Differentiation: Can histology and/or grade be coded from a metastatic site? See discussion. | Example 1: No pathology specimen is available from the primary site for a lung primary. Rib biopsy demonstrated "anaplastic adenocarcinoma."
Example 2: Lung tissue biopsy revealed "poorly differentiated non-small cell carcinoma" for a lung primary. Pleural effusion cytology was consistent with "adenocarcinoma". |
For tumors diagnosed prior to 2007:
Example 1: Code the Histology and Grade, Differentiation fields to 8140/39 [adenocarcinoma, NOS, grade not stated]. Because there was no microscopic examination of tissue from the primary site, the histology may be coded from the microscopic examination of the tissue from a metastatic site. Do not code grade from a metastatic site regardless of whether the involvement of the metastatic site is by direct extension or by discontinuous metastases.
Example 2: Code the Histology and Grade, Differentiation fields to 8046/33 [non-small cell carcinoma, poorly differentiated]. Because there is a microscopic examination of tissue from the primary site, that information should be used to code histology rather than a cytology of a metastatic site.
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. |

20021030 | Grade, Differentiation--All Sites: Why was the decision made not to code all "3-component differentiation systems" the same way that Bloom-Richardson is coded? For example, SEER codes a low grade BR to 1 for the Differentiation field and a low grade for other grading systems to 2. See discussion. | Our Pathologist Consultant agrees with SEER's guideline to code the Bloom-Richardson and B&R modifications of low, intermediate and high to 1, 2 and 3 respectively and thinks all 3-component systems should be coded that same way because it better represents the differentiation of the tumor. In his opinion, coding all other 3-component systems to a differentiation of 2, 3 and 4 respectively, is overstating the degree of differentiation. | The rules for coding histology are approved and used by all of the major standard setters through agreements reached in the NAACCR Uniform Data Standards Committee. This issue is under review by our medical advisors and a special committee. Changes will be taken to the Uniform Data Standards Committee for review and approval. | 2002 |

20020018 | EOD-Lymph Nodes/EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined--Cervix: What codes are used to represent these fields for a cervix primary when the only information on lymph nodes is a CT of the pelvis showing "pelvic adenopathy" (no surgery was done)? | Code the EOD-Lymph Nodes field to 9 [unknown]. Code the Pathologic Review of Number of Regional Lymph Nodes Positive field to 98 [No nodes examined] and the Lymph Nodes Examined to 00 [No nodes examined] because there was no resection of the primary organs. Adenopathy, NOS, per SEER guidelines, is not coded as lymph node involvement | 2002 | |
|
20021137 | Multiple Primaries (Pre-2007)--Soft Tissue: Does SEER agree that one primary of the soft tissues of pelvis [C49.5] should be reported when a pathologic diagnosis for bilateral herniorrhaphies is "right and left inguinal hernias with low grade spindle cell sarcoma"? | For tumors diagnosed prior to 2007:
Yes. This is one primary and should be coded to C49.5 [Connective, subcutaneous and other soft tissue of pelvis]. According to Rule A in ICD-O-3, the type of tumor ("sarcoma") indicates origin from a particular tissue, resulting in the primary site code of C49.5 [Inguinal region, NOS] for this sarcoma.
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. |

20021147 | Other Cancer Directed Therapy--Hematopoietic, NOS: Is "aspirin" treatment for primary polycythemia? See discussion. |
Aspirin is listed as treatment for "thrombocythemia" in the Abstracting and Coding Guide for the Hematopoietic Diseases but not for "primary polycythemia." |
Do not code aspirin as treatment for primary polycythemia (polycythemia vera). |
