20021016 | Histology (Pre-2007)/Behavior Code: What code is used to represent the histology "foci of well differentiated intramucosal carcinoma [carcinoma in situ] arising on the surface of a tubular adenoma"? The pathologist referred to this colon biopsy as "in situ". | For tumors diagnosed prior to 2007:
Assign histology code 8210 [adenocarcinoma in a tubular adenoma] and behavior code 2 [in situ]. "In situ" is specified by the pathologist.
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. |

20021045 | Histology/Grade, Differentiation--Lymphoma: What code is used to represent the histology "high grade malignant lymphoma with features of so called blastic NK cell cutaneous lymphoma [hematodermic lymphoma]" found on punch biopsy? | For cases diagnosed prior to 1/1/2010:Code the Histology field to 9709/3 [cutaneous lymphoma, NOS]. Code the Grade, Differentiation field to 8 [NK cell]. 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. |

20021139 | Date of Diagnosis/EOD-Extension--Placenta: How do you code these fields for a patient who presents with a vaginal metastatic lesion for a placenta primary? Should EOD-Extension be coded to 60 [Other genital structures NOS: vagina, ovary, broad ligament, fallopian tube] or 85 [metastasis other than lung]? See discussion. | Pt had D&C Feb 5 with features of complete mole. On March 7, pt seen for a mass just inferior to the urethral meatus. At path, vaginal introitus fragments were consistent with choriocarcinoma. At time of March 23 admit for chemo, history is given as large hydatidiform mole evacuated Feb 5. Her beta hCG titers initially fell but approximately one month later hCG titers rose. At that time, she had an obvious vaginal metastatic lesion. | For cases diagnosed 1998 or after: Code the Date of Diagnosis field to March 7, which is the date that the choriocarcinoma was first diagnosed. There was no slide review or clinical statement that the first occurrence was obviously malignant. Therefore, the vaginal mets is not progression and is codeable as extension. Code the EOD-Extension field to 60 [other genital structures, NOS] according to the current EOD scheme for placenta. Even though the mass is discontinuous, it is still included in code 60 per the guidelines of the FIGO system on which the EOD is based. | 2002 |

20021142 | Date of Diagnosis: If an originally diagnosed "benign" tumor is later discovered to have "metastasized", should the date of diagnosis be back-dated to the date the original tumor was discovered or to the date the metastatic disease was identified? | Code the Date of Diagnosis field to the date the malignancy is diagnosed. If there was a medical or pathologic review of the original benign diagnosis that indicates that the patient had cancer at the earlier time, then the earlier date is coded as the date of diagnosis. If no medical or pathologic review of the original benign diagnosis is done, then code the date of diagnosis to the date the metastasis is discovered. | 2002 | |

20021111 | Histology/Grade, Differentiation--Lymphoma/Leukemia: Do you agree with coding a diagnosis of Nasal NK/T cell lymphoma to 9719/38? | For cases diagnosed prior to 1/1/2010:Yes. Code the Grade, Differentiation field to 8 [NK cell] rather than 5 [T-cell]. Code the Histologic Type to 9719/38 [NK/T-cell lymphoma, nasal and nasal-type with Cell indicator of NK (8)]. 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. |

20021201 | EOD-Extension--Lymphoma: What code is used to represent this field for a lymphoma with retroperitoneal lymph node involvement and splenomegaly? | For cases diagnosed 1998-2003:
Per AJCC, code spleen involvement which is demonstrated by:
1. Unequivocal palpable splenomegaly alone. 2. Equivocal palpable splenomegaly with radiologic confirmation (ultrasound or CT). 3. Enlargement or multiple focal defects that are neither cystic nor vascular (radiologic enlargement alone is inadequate).
If the spleen is proven to be involved, code extension for this case as 20 [Involvement of two or more lymph node regions on the same side of the diaphragm; Stage II].
If the spleen is not proven to be involved, code extension as 10 [Involvement of a single lymph node region; Stage I]. |

|
20021133 | First Course Treatment--All Sites: The patient has undergone part of the planned first course of treatment when a metastatic deposit is identified. If the patient continues with the planned first course of treatment, should the modalities of treatment given after the metastatic deposit is discovered be included in the coding of the first course of cancer-directed treatment fields? |
Yes, those modalities should be counted as part of first course of cancer-directed treatment if the patient continues with the planned first course. For example, if patient has the originally planned type of surgery, radiation, or drug protocol, then code the given treatment as first course. Caution: It is not a change in the treatment plan if the drugs are changed but the action of the drugs remains the same. This is still first course. However, if the treatment is changed from a chemotherapy drug to a hormonal drug following the discovery of the mets, do not code the hormonal therapy as first course. |

20021106 | Histology (Pre-2007)/Diagnostic Confirmation: What code is used to represent the histology that initially presents on uterine curettage as a hydatidiform mole and after pulmonary metastases develop a month later, the clinical diagnosis is "metastatic gestational trophoblastic disease"? | For tumors diagnosed prior to 2007:
Code the Histology field to 9100/3 [Choriocarcinoma]. Gestational trophoblastic neoplasia includes the diagnosis of choriocarcinoma.
Code the Diagnostic Confirmation field to 8 [Clinical diagnosis only] based on the information above. However, if imaging, direct visualization, or another method identified the pulmonary metastases, then code the Diagnostic Confirmation accordingly.
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. |

20021173 | Histology (Pre-2007): What code is used to represent a review of slides histology of "in situ squamous cell carcinoma and multiple detached fragments of atypical papillary squamous epithelium; highly suspicious for invasive carcinoma"? See discussion. | The original pathologist indicated a final diagnosis of moderately differentiated squamous cell carcinoma. The slides were sent for review to another facility. The reviewing pathologist rendered the diagnosis stated in the question section. | For tumors diagnosed prior to 2007:
Code the Histology field to 8070 [squamous cell carcinoma].
The review diagnosis was also squamous cell carcinoma. The expression "atypical papillary squamous epithelium" does not modify the cancer histology.
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 |
