Reportability/Histology--Gallbladder: Is intracholecystic papillary-tubular neoplasm (ICPN) with extensive high grade dysplasia of the gallbladder reportable?
Report intracholecystic papillary neoplasm (ICPN) with high-grade dysplasia (8503/2) of the gallbladder.
Reportability/Histology--Colon: Is tubular adenoma with high grade dysplasia and focal invasion from a pathology report of a colon biopsy reportable?; if so, what is the histology code?
Tubular adenoma with high grade dysplasia and focal invasion is reportable. Assign the histology code and behavior as 8210/3 (Adenocarcinoma in tubular adenoma).
NAACCR Guidelines for ICD-O-3 Implementation discuss the term high grade dysplasia (without invasion). High grade dysplasia and related terms are under review and study for consideration as a reportable neoplasm. Registries should check with their state reporting legislation to see if included in the reporting requirements.
First Course Treatment: What code is used to represent each treatment modality field when there is no indication that a particular modality of treatment was recommended or started?
Code the individual treatment fields to 0 or 00 [None] when the modality is not addressed in the treatment plan (or when a treatment plan is lacking) and there is no indication that a particular modality of treatment was recommended or started.
Grade, Differentiation--All Sites: If the grade given for the primary site is from a provisional diagnosis and the grade given for a metastatic site is from a final diagnosis, should we follow the SEER rule that says to code the grade as stated in the final diagnosis (e.g., Provisional diagnosis: High grade papillary serous carcinoma of ovary. Final dx: poorly differentiated adenocarcinoma in a caval lymph node)?
Code the Grade, Differentiation field to 4 [High grade] from the examination of the ovary (primary site). Do not code grade from a metastatic site.
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.
Histology--Lymphoma: How is "histiomonocytic lymphoma" coded?
For cases diagnosed prior to 1/1/2010:Assign code 9755 [Histiocytic sarcoma; True histiocytic lymphoma]. "Histiomonocytic" is not standard terminology, according to our expert consultant. However, 9755 is the best code to assign.
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.
MP/H Rules/Multiple primaries--Colon: Does rule M7 apply here (A frank malignant or in situ adenocarcinoma and an in situ or malignant tumor in a polyp are a single primary)? Can the frank malignant adenocarcinoma be any specific type of adenocarcinoma for this rule to apply?
A patient has 2 synchronous tumors in the ascending colon. The first is grade 3 adenocarcinoma with signet ring differentiation and focal mucinous features (8255/3). The second is grade 2-3 adenocarcinoma in a tubulovillous adenoma (8263/3).
M7 applies to this case. The frank adenocarcinoma can be a specific type of adenocarcinoma.
Grade, Differentiation--Breast: Does SEER agree with our pathologist who contends that "by convention lobular carcinoma is considered to be grade 2"?
No. SEER does not have a default grade code for lobular carcinoma. Code the grade as stated in the pathology report. If no grade is stated, code the Grade, Differentiation field to 9 [Cell type not determined, not stated or not applicable].
Multiple Primaries/Histology--Mycosis Fungoides/Cutaneous T cell Lymphoma: Physicians often use the terms cutaneous T cell lymphoma (CTCL) and mycosis fungoides interchangeably and yet the SEER Single versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table indicates that these 2 diagnoses represent separate primaries. Do these cases represent one primary? If so, what histologic type should they be coded to?
For cases diagnosed prior to 1/1/2010:The patient does not have two different malignancies. Code the Histology field to 9700/3 [mycosis fungoides], the specific type of cutaneous T cell lymphoma. Mycosis fungoides is one of several types of cutaneous T cell lymphoma. Physicians often refer to mycosis fungoides by the "umbrella term" cutaneous T cell lymphoma.
The table indicates that the broad category of "T/NK-cell NHL" (which includes CTCL) and mycosis fungoides are presumably separate primaries because several entities are included in that broad category. In the specific case cited above, one entity (CTCL) within the broad category (T/NK-cell NHL) and mycosis fungoides are not separate primaries.
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.
Unless the disease is specified as primary, idiopathic, essential, or the physician states there is a myeloproliferative neoplasm, the term thrombocytosis, NOS is not reportable. Thrombocytosis, NOS, is the presence of high platelet counts in the blood. Thrombocytosis can be associated with chronic infections and other diseases as well as with myeloproliferative disease. Thrombocytosis, NOS is listed in Appendix F as a Non-Reportable Term.
