20010162 | EOD-Size of Primary Tumor: Should the code 001 in tumor size be used for tumors described as having "focal" involvement? See discussion. | Is tumor size coded to 001 for the following examples:
Example 1: Focal adenoca in left lobe on prostatectomy. Example 2: Multifocal ductal carcinoma of breast on mastectomy. |
Example 1 and 2: There is insufficient information in the examples to determine whether EOD-Size of Primary Tumor should be coded to 001.
The instructions are that code 001 is used for a microscopic focus or foci of tumor only. That means that the tumor is small enough that it could not be seen by the naked eye, nor would it be palpable. Be careful with the term "focal" because it is most often used to describe tumor cells grouped or concentrated in one area as in example 1. There is no implication that this focus was microscopic only. Was it mentioned in the gross or macroscopic portion of the pathology report? If so, it is not coded to 001. Was it palpable? If so, it is not coded to 001.
Example 2 cites a multifocal breast cancer. Again, did the pathologist visualize the cancer (was it reported on the gross or macroscopic portion of the pathology?) If so, do not use code 001. Was the lesion palpable? If so, do not use code 001. |

20010148 | EOD-Extension--Lymphoma: Would a lymphoma involving mesenteric and retroperitoneal nodes (both site code C77.2) be coded to extension 10 [Involvement of a single lymph node region; Stage I], based on the fact that while more than one "chain" is involved only one "region" is involved? |
For cases diagnosed 1998-2003: Code the EOD-Extension field to 20 [Involvement of two or more lymph node regions on the same side of diaphram]. The AJCC lists mesenteric as a core nodal region, but does not list retroperitoneal lymph nodes as a part of this region, so retroperitoneal is a separate region. The EOD staging scheme for lymphoma uses lymph node REGIONS as the criteria for assigning the extension code. Use the AJCC Cancer Staging Manual as the definitive source for classifying lymph node regions, not the ICD-O-3. If it is a separate LN region per the AJCC, it is coded in the EOD as a separate region. According to the AJCC curator, the nodal regions are defined in Kaplan's book on Hodgkin disease. Bilateral cervical, or axillary, or hilar, or pelvic, or inguinal nodes count as two regions. Mediastinal and para-aortic lymph nodes count as one region regardless of laterality as they are centrally located. A large mediastinal mass constitutes one region involved regardless of the size. |

20010166 | Reportability--Myelodysplastic Syndrome: How we handle cases of myelodysplastic syndromes identified in 2001 casefinding documents that are determined to have an "unknown diagnosis" date after review of the patient's hospital medical record? |
Myelodysplastic syndrome cases with unknown dates of diagnosis identified in pre-2001 casefinding documents should not be accessioned and are not SEER reportable. For cases identified in 2001 casefinding documents, when the diagnosis date cannot be confirmed using the medical records typically accessed by the registrar or central registry staff, do not accession these cases; they are not SEER reportable. This default applies only to those cases identified in 2001 casefinding documents. For cases identified in 2002 or later casefinding documents, the attending physician should be contacted and asked to clarify the diagnosis date for cases identified with unknown dates of diagnosis. Clarifying the diagnosis date is necessary to determine whether the case is reportable and whether it should be accessioned. |

20010055 | EOD-Lymph Nodes--Breast: Are lymph nodes described as being either "keratin positive" or "keratin positive for metastasis" to be coded as involved lymph nodes? | For cases diagnosed between 1998-2003:
Lymph nodes that are only "keratin positive" would not be coded as involved lymph nodes. The pathologist uses this expression to mean that the nodes stained positive for keratin that does not mean they are also involved with cancer.
However, if the pathologist uses these stains to make a definitive diagnosis of metastatic carcinoma (i.e., uses the expression "keratin positive for metastasis"), then code the nodes as involved. |

20010104 | Date of Diagnosis--Lung: Based on Note 7 in the lung EOD, should the Date of Diagnosis field be coded to an earlier CT scan date with a reported diagnosis of "RUL mass with mediastinal lymphadenopathy" or to the later biopsy date with a reported diagnosis of small cell carcinoma? See discussion. | Note 7 states that "mediastinal lymphadenopathy" indicates involved lymph nodes for lung primaries. Should the date of diagnosis be back-dated to the date of the scan? | For cases diagnosed 1998-2003:
No, code the Date of Diagnosis field to the later biopsy date. Note 7 is intended for use in coding the EOD-Extension field, not the Date of Diagnosis field. The earlier scan has a diagnosis of RUL "mass" not a "malignancy" so the fact that there is mediastinal lymphadenopathy mentioned in that scan is not used to help determine date of diagnosis. |

20010006 | Terminology/EOD-Clinical Extension--Prostate: Is "firm" a term that implies clinically apparent prostate disease? See discussion. | PE: Prostate firm on DRE IMP: Rule out prostate cancer |
For cases diagnosed between 1998-2003:
Code the EOD-Clinical Extension field to clinically inapparent. The clinically apparent term list classifies "firm" as "maybe" being involved. If a maybe term such as "firm" is the only description available, code as clinically inapparent. |

20010084 | EOD-Size of Primary Tumor: Can you code the known size of the residual tumor in a further resected specimen if the size of the tumor in a prior excisional biopsy is unknown? See discussion. | Excisional biopsy is done prior to admission and the tumor size is unknown. Pt is admitted for a mastectomy and the residual tumor size is 5 mm. | For cases diagnosed between 1998-2003:
Code the EOD-Size of Primary Tumor field to 999 [unknown]. The majority of the tumor would have been removed during excisional biopsy and it is possible that the tumor could have been quite large. |

20010123 | Scope of Regional Lymph Node Surgery/EOD-Lymph Node fields: How do you code these fields if a pt has multiple lymph nodes surgeries at different times? See discussion. | Example: 1/01/03 Biopsy of 1 sentinel lymph node: positive for metastasis. 1/10/03 Modified radical mastectomy and axillary lymph node dissection: ductal carcinoma with 8 neg lymph nodes. | For cases diagnosed 1/1/2003 and later: Code Scope of Reg LN Surgery to 7. Code EOD Lymph Nodes field to 6. Code EOD Pathologic Number of Reg LN Positive and Examined fields to 01 and 09 respectively.
For the Scope of Reg LN Surgery use the highest applicable code number if more than one Scope of Reg LN Surgery was performed. The EOD lymph node fields are cumulative and count all lymph nodes removed during the diagnostic and first course treatment procedures. |

20010136 | Reason no treatment/Surgery of Primary Site: Does the "Reason for No Cancer-Directed Therapy" field only relate to the "Surgery of Primary Site" field? If so, for what diagnosis years is that effective? Have SEER's coding guidelines changed over time? See discussion. | Whenever a surgical procedure is performed that results in a non 0 or 9 code in any one of the Surgery fields, should the Reason for No Site-Specific Surgery field be coded to 0 [Cancer-directed surgery performed]? | For cases diagnosed 2003 and forward: The field "Reason for No Surgery of Primary Site" applies only to surgery of primary site. This is a change from the pre-2003 instructions. | 2001 |
|
20010100 | Grade, Differentiation--Lymphoma/Leukemia: What code is used to represent this field when the phenotype is combined B cell and T cell? | For cases diagnosed prior to 1/1/2010:Code the Grade, Differentiation field to 9 [Cell type not determined, not stated or not applicable]. There is no combination code for B cell and T cell. There is also no hierarchy established for choosing one code over the other. Therefore coding such a case as a pure B cell or a pure T cell would misrepresent the phenotype.
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. |
