Primary Site/Histology--Lymphoma: How are these fields coded when the final diagnosis per the pathology report is, "Soft tissue and skeletal muscle, left thigh--Large B cell lymphoma with polyclonal and mature t-cells, involving the soft tissue"?
For cases diagnosed prior to 1/1/2010:Site: C492 [Soft tissue thigh]
Histology: 9680/36 [T-cell rich large B-cell lymphoma]
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 Size of Tumor/CS Extension--Brain and CNS: How should these fields be coded for benign CNS tumors?
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 Extension as 05 [Benign or borderline brain tumors]. Code the size of the tumor if specified. Otherwise code CS Tumor Size as 999 for benign CNS tumors.
Reportablility--Breast: Is lobular neoplasia, grade 2 reportable? See Discussion.
Path report reads: Lobular neoplasia, grade 2.
According to the AFIP nomenclature for DCIS (taken from the WHO terminology), this would be the equivalent of LCIS. But nowhere can I find this specifically applies to lobular in the same way that ductal neoplasia is treated.
According to the editors of ICD-O-3, lobular neoplasia grade 2 is not equivalent to LCIS. It is not a reportable term. Lobular neoplasia and lobular intraepithelial neoplasia are equivalent terms having a three grade system. Only LN/LIN grade 3 would be reportable since those terms are analogous to ductal intraepithelial neoplasia grade 3.
EOD-Extension--Breast: If the pathology report states "infiltrating duct carcinoma...measuring 7mm in diameter...focal areas of intraductal carcinoma," do we code this field to 14 [Invasive and in situ components present, size of entire tumor coded in Tumor Size and in situ described as minimal] or to 16 [Invasive and in situ components present, size of entire tumor coded in Tumor Size and proportions of in situ and invasive not known]?
For cases diagnosed 1998-2003: If 7mm is the measurement of the infiltrating duct portion of this cancer, assign extension code 13 [Invasive and in situ components present, size of invasive component stated and coded in Tumor Size].
If 7mm is the size of the whole malignancy and the size of the invasive portion cannot be determined, assign extension code 14 [Invasive and in situ components present, size of entire tumor coded in Tumor Size (size of invasive component not stated) and in situ described as minimal (less than 25%)]. "Focal areas of in situ carcinoma" qualifies as minimal.
Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Kidney: How many primaries, with what histology(ies) should be coded when nephrectomy pathology specimen shows separate tumors of "renal cell carcinoma [clear cell type]" and "renal cell carcinoma [granular cell type]"?
For tumors diagnosed prior to 2007:
Abstract two primaries. This is an example of two tumors with different histologic types in the same site. The right kidney has two separate tumors.
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.
Reporting Source: Is an ER patient who is diagnosed on peripheral smear with an acute leukemia coded as an outpatient if the patient died while in the process of being admitted for treatment or is the patient coded as a death certificate case?
Code reporting source as 1 [Hospital Inpatient/Outpatient or Clinic] for the case above. This case will be abstracted using information from the outpatient/ER record (and the death certificate).
First Course Treatment: If a patient makes a blanket refusal of all recommended therapy or refuses all treatment before any therapy was recommended, are only immunotherapy and hematologic/endocrine therapies to be coded as refused (code 87)? Or should all treatment modalities be coded as refused if a patient makes a blanket refusal? Or should none of the treatment modalities be coded as refused because we do not know what would have been recommended? See Discussion.
Coding instructions for immunotherapy and for hematologic/endocrine procedures state that Code 87 is to be assigned if either of the following circumstances apply: 1) If the patient made a blanket refusal of all recommended treatment. 2) If the patient refused all treatment before any was recommended. These instructions are not included for other treatment modalities.
When the patient refuses treatment, the first course of therapy is no treatment. Code all treatments as refused.
First Course Treatment/Immunotherapy--Colon: Can "Sandostatin" be coded for treatment of carcinoid tumors of the colon because it flushes tumor cells from the colon in addition to controlling diarrhea?
Do not code Sandostatin (Ocreotide Acetate) as treatment. This is an ancillary drug used to treat symptoms of diarrhea. SEER Book 8 is undergoing revision and will include this change.
CS Site Specific Factor 1--Colon: If the registrar did not support the CEA code recorded with the appropriate text documentation, should the central registry accept the registrars coding or change the value to 999?
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.Accept your registrars' codes at your discretion. It is encouraged, but not required, to enter text for CS data elements. These cases do not automatically default to code 999.
