CS Reg LN Pos/Exam--Colon: For a patient with both a prostate and colon primary, if the pathology report indicates that 2 of the 3 regional lymph nodes to the colon are positive for a prostate malignancy, how should these fields be coded for the colon primary?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.For the colon primary, code Reg LN Pos 00 [all nodes negative]. Code Reg LN Exam 03 [three nodes examined].
Three lymph nodes were examined and found to be negative for metastatic colon cancer.
CS Tumor Size/CS Eval--Breast: How are these fields coded when there is a clinical size recorded but the tumor size is not specified on the pathology report associated with a subsequent resection? See Discussion.
4/8/04 excisional biopsy of 1.5 cm palpable mass. Path: gives a specimen size only and states that there is a nodular firm area that correlates with the clustered microcalcification on radiograph. No pathologic tumor size is given. Would the size be coded to the clinical size of 1.5 cm? The patient did have surgery but the only size available is a clinical one. Because the size is clinical, is the CS Eval field coded to 0 [No surgical resection done. Evaluation based on PE...]?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Clinical size can be coded when the patient has had surgery. For the case above, code the tumor size as 015 [1.5 cm] using the clinical information. The CS Tumor Size/Extent Eval field refers to both tumor size and extension. In this case, record the eval field as 0 or 1 (which ever is appropriate). The tumor size sets the T category unless the resection shows skin or chest wall or dermal lymphatic involvement.
CS Eval--Ovary: How is CS Mets Eval coded when the patient has positive pleural effusion confirmed by cytology?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Code CS Mets Eval for the example above 3 [path exam of metastatic tissue] assuming there has been no pre-treatment. Positive cytology is required for confirmation of pleural effusion for an ovarian primary.
Reportability--Brain and CNS: Does a case of astrogliosis meet the criteria for gliomatosis cerebri? See Discussion.
Case clinically stated to be a glioma of the brain. Pathology from resection states astrogliosis.
Anderson's Pathology defines astrogliosis as astrocytic proliferations. Gliomatosis cerebri is defined as diffuse neoplastic transformation of poorly differentiated astrocytes over a wide area; predominantly invovles hemispheric white matter.
The pathologic diagnosis for this case, astrogliosis, is not reportable to SEER. Take the definitive diagnosis for this case from the pathology report from the resection. The pathology report takes precendence over the clinical diagnosis.
Grade, Differentiation/Priorities: Which has priority, the differentiation or the nuclear grade for a liver biopsy histology described as "well differentiated hepatocellular carcinoma, nuclear grade 3/4"?
For most sites, differentiation has priority over the nuclear grade when both are specified (excluding breast and kidney). Assign grade code 1 [well differentiated] to the example above.
CS Eval--All Sites: If any of the CS fields (TS/Extension, LN, or Mets) are based on the TNM and there is no text documenting the basis for the evaluation, are the evaluation fields coded to 0 instead of 1?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Assign code 0 [No surgical resection done...based on physical exam...or other non-invasive clinical evidence] to the corresponding eval fields when CS Extension, Lymph Nodes or Mets at Diagnosis are coded based only on the TNM and no further information is available.
Reportability/Diagnostic Confirmation--Leukemia: What is the diagnostic confirmation if a positive BCR/ABL result is diagnostic of a malignancy in a patient suspected to have chronic myelogenous leukemia? See Discussion.
Example 1: Peripheral smear states: "No morphologic evidence of chronic myelogenous leukemia."
Addendum: Molecular diagnostic studies showed a positive rearrangement for the BCR gene with the M-bcr (CML type) and of bcr-abl transcript expression".
Example 2: Hematopathology is negative.
Molecular diagnostic study: "fluorescent in situ hybridization (FISH) studies exceeded the limits established by the XXX Cytogenetics Laboratory for this probe set, and thus, demonstrated statistical evidence of BCR/ABL fusion."
For cases diagnosed prior to 1/1/2010:
Do not determine reportablility using cytogenetics or molecular studies alone.
Since these are not routine screening tests, we suggest that you query the physician and review the medical record to see what prompted the study and what is being done with the result, but the test alone is not in and of itself sufficient to report the case.
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.
CS Extension/CS Site Specific Factor--Breast: How is extension (localized or unknown) and SSF6 (entire tumor in situ or 888) coded for an in situ breast primary in which bone metastasis is diagnosed 4 months following the mastectomy? See Discussion.
In situ breast primary with bone mets. No mets work up prior to mastectomy done 2/04. Path: 2.5 cm mass: ductal carcinoma in situ, solid type, with comedonecrosis (no invasive carcinoma found in mastectomy specimen). Bone scan done 4/04 showed compression fractures. MRI 6/04 showed diffuse metastatic disease of the bones.
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
First, determine whether the bone mets in this case are progression of disease. If the patient was asymptomatic at the time of the mastectomy, the bone mets are disease progression, not initial stage.
If the initial stage includes the bone mets and they are not disease progression, extension must be coded to at least 10. Code site-Specific Factor 6 to 040 [Size of entire tumor coded, size of invasive component not stated].
2004 SEER Manual Errata/Surgery of Primary Site--Lymphoma: Item 9.a on page 178 is incorrect. Do not assign surgery code 98 to lymphoma, primary in lymph nodes. See Appendix C, page C-707 for Lymphoma (primary in lymph nodes) surgery codes.
Delete item 9. a. i. ii. and iii. on page 178 of the 2004 SEER Manual. This correction will be included in the next errata.
