20021209 | EOD-Extension/EOD-Lymph Nodes--Rectosigmoid: How do you code these fields for a scan-based clinically staged T3 N1 rectosigmoid primary in a patient who received chemotherapy and radiation prior to a resection that demonstrated invasion only into the muscularis and no positive lymph nodes? | For cases diagnosed 1998-2003:
Use the best information available, in this case, the clinical staging, to code EOD. Code the EOD-Extension field to 40 [Invasion through muscularis propria or muscularis, NOS] and the EOD Lymph Node field to 3 [Regional lymph node(s) NOS] because the case had a clinical stage of T3 N1. EOD is coded using the most extensive clinical or pathologic stage. |

20021099 | Reportability/Histology (Pre-2007)--Pancreas: Are the following pancreatic tumors with mention of "low grade malignant potential/borderline" reportable to SEER? If so, what histology and behavior codes should be used? See discussion. | 1. AFIP diagnosis: Pancreas, tail, resection: Mucinous cystadenocarcinoma (mucinous cystic neoplasm) of low grade malignant potential. Comment: There are no reliable histomorphologic features which can separate these neoplasms into benign and malignant tumors, and so we consider them all to be low grade malignant tumors.
2. Whipple resection: Intraductal papillary mucinous tumor of the pancreas with extensive low grade and multifocal high grade ductal dysplasia (so-called borderline tumor and carcinoma in-situ). |
For tumors diagnosed prior to 2007:
Both tumors are reportable to SEER.
1. Code the Histology and Behavior Code fields to 8470/3 [Mucinous cystadenocarcinoma, NOS].
2. Code the Histology and Behavior Code fields to 8453/2 [Intraductal papillary-mucinous carcinoma, non-invasive].
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. |

20021066 | Histology: How do we code this field when a less representative specimen has a more specific morphology? See discussion. | Example: Biopsy revealed endometrioid adenocarcinoma and the resection demonstrated adenocarcinoma, NOS. Do we code histology per the most representative sample, or to the more specific morphology? | Code the histology using the pathology report from the most representative specimen, even if that histology is less specific. For the case example above, code 8140 [adenocarcinoma, NOS]. The rationale is that a diagnosis from a smaller specimen will be less accurate and less representative of the true histology compared to a larger tumor specimen. |

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. |

20020062 | Histology (Pre-2007): Can the histology code 8582/3, "thymoma, mixed type, malignant" only be used when you have a thymoma with both type A and type B features? See discussion. | Can this same histology be used when you have two type B features in the thymoma specimen? What code is used to represent the histology?
Example 1: Thymoma, spindle cell and epithelial type Example 2: Thymoma, mixed lymphocytic and epithelioid type |
For tumors diagnosed prior to 2007:
For example 1, code histology to 8582 [Thymoma, type AB]. This code is only applicable to "Type AB thymoma [mixed]" in the WHO classification. Use 8582 only for thymomas with type A and type B features. Spindle cell is a type A feature and epithelial is a type B3 feature.
For example 2, code histology to 8585 [Thymoma, type B3]. Lymphocytic is a B1 feature (8583) and epithelial is a B3 feature (8585). There is no type A component. Code the histology based on ICD-O-3 rule K on page 34.
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. |

20021096 | Grade, Differentiation--Bladder: What codes are used to represent this field for the four bladder cases described in the discussion section that have a combination of grades mentioned in the pathology reports? See discussion. | 1) Final path diagnosis: papillary transitional cell carcinoma, high grade. Micro description states: High grade, poorly differentiated carcinoma. 2) Well to moderately differentiated papillary transitional cell carcinoma, grade 1-2/3. 3) Urothelial carcinoma, high grade (poorly differentiated, grade 3 of 3). 4) High grade papillary urothelial carcinoma (papillary transitional cell carcinoma, grade 3 out of 4). |
For cases diagnosed January 2004 and forward: 1) Grade 4. High grade is coded 4. Code the grade stated in the final diagnosis. 2) Grade 3. Grade 1-2/3 is coded 3. Use the three-grade conversion table in the 2004 SEER manual. 3) Grade 4. Grade 3 of 3 is coded 4. Use the three-grade conversion table in the 2004 SEER manual. 4) Grade 3. "Grade 3 out of 4" is coded 3 and is more precise than "high grade." |

20021178 | Histology (Pre-2007): What code is used to represent the histology "poorly differentiated invasive transitional cell carcinoma with extensive squamous and focal glandular differentiation"? | For tumors diagnosed prior to 2007:
Code the Histology field to 8120/33 [transitional cell carcinoma, NOS, poorly differentiated]. The ICD-O-3 does not have a separate code for transitional cell carcinoma with squamous and/or glandular differentiation.
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. |

20021070 | CS Extension/CS Lymph Nodes--Breast: How would you interpret the phrase "axillary lymph node tissue, not clearly a lymph node" or the phrase "satellite nodule of invasive tumor, left axillary lymph node or chest wall tissue"? See discussion. | A lumpectomy with axillary lymph node dissection and removal of nodule in anterior axillary line revealed negative lymph nodes. The nodule specimen was labeled "axillary lymph tissue, not clearly a lymph node". The microscopic description for that specimen stated "Fibroadipose tissue. A fragment of a lymph node is incidentally sampled in block 4 and it is free of tumor". The final path dx stated "Satellite nodule of invasive tumor, left axillary lymph node, or chest wall tissue. Comment: If the tissue is considered chest wall this would be a stage IIIB. If it is considered an intramammary satellite nodule, this is a stage I". The clinician repeated what the comment said, and added "If lymph node mets, this is a stage II." | Code the invasive tumor in the axillary area as a regional lymph node metastasis. According to the AJCC, cancerous nodules in the axillary fat adjacent to the breast, without histologic evidence of residual lymph node tissue, are classified as regional lymph node metastases. | 2002 |
|
20020050 | EOD Clinical Extension--Prostate: Can you assign code 15 if there is no TURP and no physical exam? See discussion. [Code 15 = Tumor identified by needle biopsy, e.g. for elevated PSA, (T1c)] |
Prostate case: Elevated PSA, Prostate u/s: no abnormal findings, Prostate biopsy: adenocarcinoma. Can this be clinically coded as 15? According to Prostate EOD Coding Guide (6/2001), code 15 requires documentation that the physical exam was negative, but in this case, we have no physical info. | For cases diagnosed 1998-2003:
Code the EOD Clinical Extension field to 30-34 when there is no documentation saying that the physical examination was negative. |

|
20021138 | Grade, Differentiation--All Sites: What code is used to represent this field when a pathology report describes a tumor as a low grade neoplasm consistent with a specific histologic type (e.g., Low grade neoplasm consistent with carcinoid)? | Code the Grade, Differentiation field to 2 [Low grade]. | 2002 |
