Report Question ID Question Discussion Answer Cancer Site Category Data Item Category Year
20031083 Grade, Differentiation: How is this field coded when the only description in the pathology report is "non-high grade?" Code "non-high grade" as 9 [unknown]. N/A N/A 2003
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.

20031162 Multiple Primaries/Histology--Hematopoietic, NOS/Lymphoma: How many primaries are represented and what are the histologies for "B-cell lymphoma with immunophenotypic findings consistent with hairy cell leukemia" found on a bone marrow biopsy? See Description. Pathologist completed AJCC lymphoma staging form indicating this case should be abstracted as a lymphoma.

For cases diagnosed prior to 1/1/2010:Abstract as one primary, 9591/3 [B-cell lymphoma, NOS]. The bone marrow diagnosis indicates that the main/definite diagnosis is B-cell lymphoma, with a lesser indication of hairy cell leukemia. Both of these are mature B-cell neoplasms according to the WHO histological classification.

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.

20031193 Surgery of Primary Site--Lung: Is a core-out of the main bronchus coded in this field? See Description. Patient with right lung cancer was not a surgical candidate because of extent of disease. Prior to receiving radiation, patient underwent bronchoscopy, which revealed obstruction from right main bronchial tumor. Core-out of the tumor was undertaken, and a specimen was sent for path evaluation. The physician stated that this was a palliative procedure to relieve obstruction.

Do not code bronchoscopy to clear the airway as surgery of primary site. When combined with laser therapy, cryosurgery, or other tumor destruction, or when combined with excision of tumor, code as surgery of primary site.

For cases diagnosed 1998-2003: Code surgery of primary site for the case described above to 23 [Excision, NOS]. Tissue was excised and sent to pathology.

 Lung Surgery of Primary Site 2003
20031051 Histology (Pre-2007)/Sarcoma: What code is used to represent the histology "Ewing's Sarcoma/Primitive Neuroectodermal Tumor (PNET)"? See Description. A comment on one path report states "some authors consider both Ewing's & PNET to be the same biologic entity given that they share the same translocation between chromosomes 11 & 22." The pathologists at our children's hospital agree with this statement and contend that the two should have the same histologic code.

For tumors diagnosed prior to 2007:

Code histology as 9260/3, Ewing sarcoma. Ewing sarcoma is a specific histology on the continuum of primitive neuroectodermal tumors. Code Ewing sarcoma as it is more specific than PNET, NOS.

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.

20031198 Surgery of Primary Site/Date Therapy Initiated--Head & Neck: Would a biopsy, NOS, that removed the majority of the tumor be used to code these fields? See Description. Patient underwent biopsy, NOS, of a carcinoma of the tongue. Subsequent glossectomy revealed microscopic focus of residual squamous cell carcinoma. If the biopsy NOS removed all macroscopic disease, code the date of the biopsy NOS as the date therapy initiated. If macroscopic disease remained following the biopsy NOS, code the glossectomy date as the date therapy initiated. Head & Neck Date therapy initiated, Surgery of Primary Site 2003
20031205 EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined: How are these fields coded when an autopsy report reveals pathologically involved regional lymph nodes but does not state how many nodes were positive nor how many were examined? See Description. A final autopsy report described widely disseminated adenocarcinoma, probably lung primary. Metastatic tumor in brain, lungs, and in lymph nodes. The Gross description of the autopsy report stated that there were numerous metastases to hilar and mediastinal lymph nodes. The Micro description of the autopsy report did not add any clarification. In the absence of a stated number of lymph nodes, the options for coding number of regional lymph nodes examined are codes 96-98. These codes include descriptions of surgical procedures such as sampling and dissection. How do we code number of regional lymph nodes examined when the pathological examination of lymph nodes was done only at autopsy and not during a surgical procedure?

For cases diagnosed 1998-2003: The rules that apply to the use of pathology reports for EOD coding also apply to autopsy reports.

When a cancer diagnosis is made and positive lymph nodes are discovered on autopsy, in the absence of a stated number of lymph nodes, code the number of lymph nodes positive to 97 [Positive nodes but number of positive nodes not specified]. Code the number of lymph nodes examined to 97 [Regional lymph node removal documented as dissection and number of lymph nodes unknown/not stated]. An autopsy is a dissection.

20031206 EOD-Extension: How is this field coded for synchronous primaries when metastatic disease is found and there is no statement to indicate which primary is the source of the metastases? See Description. Patient was diagnosed with both esophageal and pancreatic cancer. Liver metastases were also identified. The source of the liver mets is unknown. For cases diagnosed 1998-2003: Search the record for information about the source of the metastasis. If no such information can be found, code the metastasis to both primaries. Update the abstracts when information becomes available confirming the primary site responsible for the metastasis. Assuming the liver metastases in the example above are distant (i.e. not contiguous) code extension as 85 [Metastasis]. N/A N/A 2003
20031208 EOD-Extension--Corpus uteri: How should EOD extension be coded when the pathology report shows adenocarcinoma arising in the endometrium with the statement "no invasive carcinoma identified?" For cases diagnosed 1998-2003: Code endometrial cancer with no invasion to EOD extension code 11 [Confined to endometrium (stroma)]. "No invasion" most likely means no invasion of the myometrium. Corpus uteri N/A 2003
20031210 Other Cancer-Directed Therapy--Hematopoietic, NOS: Is there a hierarchy for selecting which code to use when a patient receives more than one type of "other treatment"? See Description. Patient was diagnosed with Myelodysplastic Syndrome, probably refractory cytopenia with multilineage dysplasia. Good candidate for investigational studies for transfusion-dependent patients. Patient was enrolled in a high dose vitamin D study. Patient also received transfusions.

SEER has not established a hierarchy of the codes listed under Other Treatment. If the patient receives more than one type of other treatment as the first course of treatment, assign the code that provides the most information about how the patient was treated and use the remarks fields to explain.

Code Other Treatment for the case example above as 2 [Other experimental therapy]. Use the remarks fields to describe the transfusions and vitamin D therapy.
