20031067 | Primary Site/Histology (Pre-2007)/Sarcoma: How do you code these fields for a vulvar tumor diagnosed by FISH analysis as "extra-osseous Ewing sarcoma?" See Description. | A literature search relates soft tissue malignancy described as "extra-osseous Ewing sarcoma/PNET." Neither are compatible with site. | For tumors diagnosed prior to 2007:
Code histology as 9260/3 [Ewing sarcoma]. ICD-O-3 does not have a code for extra-osseous Ewing sarcoma (EOE). Ignore the topography code listed in ICD-O and use the code for the primary site (vulva). Site codes associated with morphology codes in the ICD-O are the most common sites and are not intended to limit coding only to those sites.
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. |

20031012 | EOD-Lymph Nodes/Extension: How does one code these fields if the clinical level of disease extension prior to neoadjuvant treatment is greater than demonstrated on pathology at time of resection? See discussion. | Breast case described clinically as a "breast mass and nodal metastases" which is treated with neoadjuvant chemotherapy and at surgery the lymph nodes are pathologically negative. | For cases diagnosed 1998-2003:
Use the combination of clinical and pathologic information to code EOD for primary site, extension and lymph nodes. Code the more extensive disease. If lymph nodes are positive clinically and not positive after neoadjuvant treatment, code lymph node involvement. If lymph nodes are negative clinically and positive on path, code lymph node involvement. When neoadjuvant treatment is administered because of a clinical statement of stage or involvement, code EOD based on this clinical information, even if later pathologic information would lead to a lesser EOD. General guideline number 6 (page 1 of SEER EOD-88 3rd ed.) points out that clinical information must be considered when coding EOD. However, do not code EOD based on clinical information disproved by pathologic findings in the absence of intervening treatment. The scenario above: The clinical involvement of the nodes justifies the neoadjuvant chemotherapy. Therefore, code EOD based on the clinical lymph node involvement. |

20031167 | Primary Site/Histology--CLL/SLL: How should these fields be coded when the pathological diagnosis of chronic lymphocytic leukemia/small lymphocytic lymphoma is made on bone marrow biopsy only but scans show lymphadenopathy? See Description. | What histology would we give these two examples? 1. Bone marrow bx: CLL/SLL. CT chest/abdomen: Mediastinal and retroperitoneal adenopathy. 2. Bone marrow bx: CLL/SLL. CT chest/abdomen: Mediastinal and retroperitoneal adenopathy suspicious for lymphoma. |
For cases diagnosed prior to 1/1/2010:If a lymph node or other solid tissue is involved initially, code to SLL. For lymphoma, any mention of lymph nodes is indicative of involvement. Involvement does not have to be proven pathologically in order to code to Small Lymphocytic Lymphoma (SLL). Code both of the examples to SLL. 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. |

20031112 | Primary Site/Histology (Pre-2007)--Unknown & ill-defined site: How are these fields coded for a markedly atypical high grade malignant neoplasm diagnosed by a fine needle aspiration of a large iliac mass, right buttock area? See Description. |
The diagnosis was made in Oct. 2002 by a CT guided fine needle aspiration of a large iliac mass, right buttock area. The cytology report says: a. positive for malignant cells, markedly atypical high grade malignant neoplasm. b. It is impossible to tell from this aspiration biopsy whether or not this represents a high grade sarcoma or a high grade carcinoma, but our consensus opinion is that this lesion is a high grade carcinoma. The combination of soft tissue topography and carcinoma morphology is Impossible by SEER edits. How should we code this? |
For tumors diagnosed prior to 2007: Code the site to C76.3 [Pelvis, NOS]. Code the histology to 8010/34 [Carcinoma, NOS, high grade]. Unless there is better information available regarding the site, assign C76.3. The information provided above does not indicate the exact site of the mass. Code the histology based on the consensus opinion stated above. 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. |

20031187 | Histology--Lymphoma: What code is used to represent the histology "monomorphic post-transplant lymphoproliferative disorder [diffuse large B-cell lymphoma]"? See Description. |
A 14 year old with a cadaver kidney transplant in 1994 for membranous glomerulonephritis presented in 6/26/03 with a right cervical LN with biopsy showing "lymph node involved by monomorphic post-transplant lymphoproliferative disorder (diffuse large B-cell lymphoma). Staging was done including a bone marrow which was negative, CSF negative. The oncologist on the case reduced the immunosuppression drugs with the final outcome being no sign of the lymphoma. | For cases diagnosed prior to 1/1/2010:Code 9680/36 [Diffuse large B-cell lymphoma]. This post-transplant lymphoproliferative disorder was diffuse large B-cell lymphoma. According to the World Health Organization, there are two types of post-transplant lymphoproliferative disorder. "Regular" post transplant lymphoproliferative disorder is not a neoplasm and is therefore not reportable to a cancer registry. The second type (sometimes called Hodgkin-like PTLD) is classified as a B-cell lymphoma, which means that it IS reportable.
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. |

20031181 | EOD-Extension--Kaposi Sarcoma: Is a "markedly enlarged spleen" involvement for cases of Kaposi Sarcoma? |
For cases diagnosed 1998-2003: No. Splenomegaly is not synonymous with "extension to" or "involvement of" the spleen in Kaposi's sarcoma. Look for a definite statement of Kaposi's lesion(s) involving the spleen. |

|
20031068 | EOD-Extension--Colon: Is a pathology description of "superficial invasion of the muscularis mucosa in the upper stalk of the polyp" coded in this field to 10 [mucosa (including intramucosal) NOS], 12 [Muscularis mucosa], or 14 [Stalk of polyp]? See Description. |
Do we use the highest applicable value because all three definitions are used in the following example? Ex: Path diagnosis: Sigmoid polyp: tubulovillous adenoma with a focus within upper portion of stalk consistent with superficially invasive (intramucosal) colonic adenocarcinoma (see Comment). Comment: ... in the upper stalk region, there is evidence of superficially invasive carcinoma which appears to be limited to the muscularis mucosa and thus would be intramucosal by classification. |
For cases diagnosed 1998-2003: Code extension as 12 [muscularis mucosae]. For this case, "upper stalk" is a reference to location rather than extension. This adenocarcinoma extends to the muscularis mucosa. |

20031007 | EOD Extension--Lung: Do we ignore pericardial effusion seen on a CXR if a subsequent lobectomy reveals only a localized tumor? See discussion. | Note 6 in the lung EOD scheme instructs us to assume that a pleural effusion is negative if a resection is done. Does this also apply to a pericardial effusion? For example, if a pericardial effusion is seen on CXR, and a subsequent lobectomy reveals only a localized tumor, should the effusion be ignored? | For cases diagnosed 1998-2003: Ignore pericardial effusion which is negative for tumor. Assume that a pericardial effusion is negative if a resection is done and the tumor is pathologically confirmed to be localized. | 2003 |
|
20031078 | EOD-Lymph Nodes--Colon: Are "multiple submucosal lymphoid collections infiltrated with tumor" or "lymphoid areas" coded as lymph node involvement, similar to the way nodules in the pericolic fat are coded? See Description. | For an adenocarcinoma in the colon, under the "lymph node" section of the final path diagnosis it states "multiple submucosal lymphoid collections infiltrated with tumor" in addition to "one of two involved lymph nodes." The micro description states "There are multiple small lymphoid areas with tumor. A definite node excised from the mesentery shows...replacement of stroma and an additional very small node shows no tumor." | For cases diagnosed 1998-2003: No, do not code tumor infiltration of lymphoid collections or lymphoid areas as lymph node involvement. However, code lymph node involvement for this case as 3 [mesenteric, NOS] because a mesenteric node is involved. Regarding tumor infiltration of lymphoid collections or lymphoid areas from our pathologist consultant: Unless the anatomy of lymph node is evident (sinuses, trabeculae, primary and secondary follicles) these aren't lymph nodes and should not be coded as such. Unless there is evidence to the contrary in the path report, I would suggest that this be considered intramural spread, not lymph node spread. |

20031132 | EOD-Lymph Nodes--Breast: Are micrometastases in the lymph nodes, found only on immunohistochemical staining, coded as positive lymph nodes? | For cases diagnosed 1998-2003: Do not code as positive lymph nodes that have micrometastases diagnosed ONLY on immunohistochemistry. By traditional diagnostic methods, these are still negative lymph nodes.
Summary Stage and EOD ignore the IHC positive micrometastases for cases diagnosed through 2003. The collaborative staging system that begins with 2004 cases and is based on the sixth edition of TNM addresses this issue. |
