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. |

20010001 | EOD-Clinical Extension--Prostate: Note 8 of the clinical EOD scheme for prostate states, "B1, Small, discrete nodule(s)<1.5 cm, and B2 Nodule(s)>1.5 cm ... " Does Note 8 still apply for cases diagnosed 1998 or later? |
For cases diagnosed 1998-2003:
Note 8 in the EOD scheme does not apply because nodule size does not apply in the 5th or 6th edition of TNM. |

20010145 | EOD-Extension: There is a one to many relationship between T values in TNM staging and SEER EOD-Extension values (one T value can be coded to many extension values). For most situations, we can typically code EOD-Extension to the lowest value in the range available for that T value per the SEER guidelines. But, what happens if another tumor feature, such as tumor size, was involved in the assignment of a T value? See discussion. | Example: Physician stages lung tumor as T2. The lowest extension code, 20, doesn't precisely fit the guidelines for a T2 tumor because the T2 stage may be based on the size of the tumor, which doesn't have anything to do with the EOD-Extension field. Should EOD-Extension be coded to 30 rather than 20? | The criteria for AJCC stage T2 consists of both size and tumor extension values. Size of tumor is recorded in the EOD-Size of Primary Tumor field. If you determine that size is the physician's sole criteria for assigning a T2 value, code an EOD-Extension value that reflects more specific information than 30 [localized, NOS]. Code to 10 or 25, depending on the case.
If the tumor size is not provided, and there is only a clinician statement that describes the lung tumor as a stage T2, code EOD-Extension to 20, the numerically lowest equivalent EOD-Extension code for the lung T2 category. |

20010135 | Histology--CLL/SLL: If a tissue diagnosis of "small lymphocytic lymphoma" is made six months after an initial blood diagnosis of "chronic lymphocytic leukemia" should the histology be updated from 9823/3 to 9670/3? | For cases diagnosed prior to 1/1/2010:Do not change the histology to small lymphocytic lymphoma (9670/3). The chronic lymphocytic leukemia has advanced/progressed and disseminated into other tissues from the blood during the last six months. If the patient presents with disease in the blood and/or bone marrow only, code to CLL. If a lymph node or other solid tissue is involved initially, code to SLL. For the case cited, the tissue involvement occurred six months after the initial diagnosis and the histology code is not changed to reflect the progression of disease.
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. |

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. |

20010070 | EOD Lymph Nodes--Colon/Rectum: How do you code "mesocolic lymph nodes" for colorectal primaries? | For cases diagnosed between 1998-2003:
Code the EOD-Lymph Nodes field to 3 [Mesenteric, NOS]. Mesocolic lymph nodes are coded as mesenteric lymph nodes. |

|
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. |

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. |

20010096 | Multiple Primaries (Pre-2007)--Bladder: Should an invasive malignancy following an in situ malignancy by more than two months be a new primary? Why? See discussion. |
Example: An in situ bladder case was diagnosed and treated. Three months later another TURB diagnosed an invasive bladder carcinoma. Is the invasive case reportable to SEER as a new primary? |
For tumors diagnosed prior to 2007: Yes. These are two primaries. In situ cancers are not included in SEER incidence rates. Incidence rates must correlate with mortality rates. 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. |

20010029 | Grade, Differentiation--All Sites: Can "Fuhrman nuclear grade" be coded if it is the only grade given for a kidney primary, or is breast the only site for which we can use a nuclear grade in coding the Grade, Differentiation field? See discussion. | Our pathologist consultant disagrees with coding nuclear grade for any site because it is only a component of the grade, in most cases, and is not adequate to use by itself.
If the Fuhrman nuclear grade system can be used by coders, will a conversion table for the system be added to the coding documentation by SEER in the future? |
For cases diagnosed 2004 and later: Fuhrman grade can be used to code the Grade, Differentiation field. | 2001 |
