EOD-Extension--Colon: What code is used to represent this field for a mid-ascending colon primary that invades through muscularis propria and into subserosal fibroadipose tissue that also presents with a "separate serosal nodule" of carcinoma within cecum that is consistent with a tumor implant (cT3, N0, M1)?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 85 [Metastasis], because the nodule of carcinoma in the cecum is not contiguous with the mid-ascending primary colon tumor.
Reportability--Pancreas: Is this reportable? Is this benign? If reportable, what histology code and behavior code should be used? A final pathology diagnosis reads: "Cystic pancreatic endocrine neoplasm (CPEN)".
"Cystic pancreatic endocrine neoplasm (CPEN)" is reportable. Assign 8150/3 based on the information provided. We consulted our expert pathologist and he states "Since metastases have been reported in a few, and all the rest of the pancreatic endocrine tumors are now designated malignant, …we are safe considering them /3 until proven otherwise. Since most of them are non-functioning, [assign code] 8150/3 unless specified as to G1 (8240/3) or G2 (8249/3)."
MP/H Rules/Multiplicity Counter--Lung: If metastatic tumors are not counted in this field, should the multiplicity counter be coded to 01 for a case with a primary left lower lobe of lung tumor with a satellite tumor in the left upper lobe?
For cases diagnosed 2007-2013:
No, code multiplicity counter to 02 [two tumors present]. According to the multiple primary rules, these two lung tumors are reported as a single primary. Record the number of tumors reported as a single primary in Multiplicity Counter.
Multiplicity Counter no longer required by SEER as of 1/1/2013.
Histology (Pre-2007): Is 8524 [lobular mixed with other carcinoma] or 8490 [signet ring cell carcinoma] used to represent a diagnosis of "infiltrating lobular with signet ring features?"
For tumors diagnosed prior to January 1, 2004:
According to our pathologist consultant, for this specific case, code to 8490 [Signet ring cell carcinoma].
Our pathologist states: "Signet ring cell carcinoma is most often a variant of lobular carcinoma (as it appears to be in this case - it is less frequently a variant of ductal), and I think it's appropriate to code it as such. Coding to lobular would also be ok, though that would lose the special feature of the signet ring cells. I would rather not code to 8524, since it is not really a mix of lobular and something else."
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.
Reportability--Ovary: Is a Stage IIIC serous borderline tumor (micropapillary type) of the ovary diagnosed in 2003 reportable?
Serous borderline tumor of the ovary diagnosed in 2003 is not reportable to SEER. The behavior code is /1 in ICD-O-3. The high stage does not make this borderline tumor reportable.
Multiple Primaries--Brain and CNS: How many primaries should be recorded in a patient with von Hippel Lindau disease that has a hemangioblastoma of the cerebellum in 2003 and a hemangioblastoma of the brainstem in 2007?
A tumor of the cerebellum (C716) and a tumor of the brainstem (C717) are multiple primaries because the topography codes are different at the fourth character of site.
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.
EOD-Extension: The medical record lacks a clear statement that metastatic workup was complete. A metastatic deposit is identified within 4 months of diagnosis and while the patient is undergoing first course of treatment. How do you code the EOD-Extension field?
For cases diagnosed 1998-2003:
In coding the EOD-Extension field, ignore metastasis that is discovered after the initial workup is completed regardless of the timeframe from diagnosis date until the date the metastatic deposit was discovered. The metastasis is progression of disease.
Any of the following represents progression of disease. Do not code the subsequently identified metastatic involvement in the EOD:
1) The metastatic workup was complete and treatment started before the procedure was done that found the metastatic involvement.
2) A procedure, such as a scan, was negative initially and a repeat of that procedure is now positive.
3) The treatment plan is developed for a localized disease process.
If you are unable to determine whether the newly discovered metastasis represents progression or is part of the initial workup, regard the metastasis as progression. Do not code the metastasis in the EOD-Extension field.
Reportability--Heme & Lymphoid Neoplasms: In the absence of any additional information regarding the disease process, is a diagnosis of "polycythemia" reportable if a patient is treated with phlebotomy?
Polycythemia (also known as polycythaemia or erythrocytosis) is a disease state in which the proportion of blood volume that is occupied by red blood cells increases. Blood volume proportions can be measured as hematocrit level. It can be due to an increase in the mass of red blood cells, "absolute polycythemia"; or to a decrease in the volume of plasma, "relative polycythemia".
The phlebotomy is a treatment for the excessive blood volume; therefore, a diagnosis of "polycythemia" without one of the modifying terms listed in the Heme DB under Alternative Names is not reportable.

CS Extension--Lung: How is "subpleural extension" coded?
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.Subpleural extension means that the tumor extends to the subpleural space, but the pleura itself is not involved. Assign the appropriate extension code based on the other facts for the case. Do not code pleural involvement.
