EOD Fields--All Sites: Is EOD information limited to what is available exactly two months from the day of diagnosis?
For cases diagnosed 1998-2003:
EOD should include all information available within four months of diagnosis in the absence of disease progression or through completion of surgery(ies) in first course of treatment, whichever is longer.
Mets known to have developed after EOD was established should be excluded.
Grade, Differentiation--Bladder: If the only indication of grade for a bladder primary is "grade 2, NOS," and we do not know the grading system being used by the pathologist, is the numeric grade 2 coded?
See the General Coding Rules on page 92 of the 2004 SEER Manual for instructions about coding grade.
If the only information available is "Grade 2," assign code 2 [Grade II].
Histology (Pre-2007)/Flag--Pancreas: How is histology coded given that 8046 [non-small cell carcinoma] of the pancreas is not on the SEER Site/Type validation listing?
For tumors diagnosed prior to 2007:
Assign 8046 [non-small cell carcinoma] for "non-small cell carcinoma" of the pancreas. If necessary, override any site/type edits.
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.
First Course Treatment/Neoadjuvant Treatment: How is Neoadjuvant Therapy--Clinical Response (NAACCR #1633) coded if a physician documents excellent response to treatment and nothing further?
Clarify the statement of "excellent" with the managing physician if possible. If no further information can be obtained, assign code 8 in Neoadjuvant Therapy–Clinical Response and document the details in text fields.
Reportability--Heme & Lymphoid Neoplasms: For cases diagnosed 2010 and later, are idiopathic thrombocytopenia and autoimmune thrombocytopenia reportable?
Idiopathic and autoimmune types of thrombocytopenia are not reportable. Thrombocytopenia and thrombocythemia are not synonyms. Cytopenia and cythemia have different definitions. See Appendix F: Non-Reportable List for Hematopoietic Diseases.
SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms. Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx.
Reportability/Histology--Heme and Lymphoid Neoplasms: Is "the differential diagnoses include, but not limited to, mantle cell lymphoma, atypical chronic lymphocytic leukemia/small lymphocytic lymphoma and a variant of marginal zone lymphoma" reportable? In the Heme manual, they use differential diagnosis that include reportable conditions as reportable. This can be found under Code 1: positive histology in the Diagnostic Confirmation Coding Instruction section page 18. The phrase "include, but not limited to" makes this not clear.
This is reportable as 9591/3, B-cell lymphoma, NOS.All diagnoses in the differential are all B-cell lymphomas. The pathologist knows it a B-cell lymphoma but has not determined the subtype. If at a later time a specific lymphoma is determined, update the histology code accordingly.
MP/H Rules/Recurrence: Is a subsequent diagnosis of an in situ tumor (bladder cancers excluded) a "recurrence" if it follows a prior invasive diagnosis of the original primary cancer made 5 years before?
For cases diagnosed 2007 or later, use the 2007 MP/H rules to determine whether or not a subsequent diagnosis (either invasive or in situ) is a new primary or a recurrence. Do not use the statement "recurrence" from the medical record to make this decision.
When evaluating a subsequent diagnosis and the MP/H rules indicate "single primary," the tumor being evaluated is a "recurrence" of the original primary cancer.
EOD-Extension--Corpus Uteri: How is this field coded for a stage III A endometrial primary with positive pelvic washings, involvement of the omental serosa, and negative lymph nodes?
For cases diagnosed 1998-2003: Code EOD-extension as 85 [Metastasis]. According to our TNM consultant, Omental metastasis is M1, Stage IVB [EOD 85].
Reportability/Histology--Pancreas: According to SINQ 20140058, solid pseudopapillary neoplasm of the pancreas is reportable (as of 2014). However, per ICD-O-3.2, this histology is not reportable until 2021+. Please clarify which is correct and clearly state the timeframe that it was reportable or not reportable.
Solid pseudopapillary neoplasm of the pancreas is reportable for cases diagnosed in 2014 and later. Report solid pseudopapillary neoplasm of the pancreas (8452/3) as the guidance in SINQ 20140058 is still in effect.
The 4th and 5th editions of the WHO Classification of Tumors of the digestive system define solid pseudopapillary neoplasm of the pancreas as a low-grade malignant pancreatic tumor.
