Reportability--Brain and CNS: Are schwannomas of the spinal cord reportable when they are intradural? See Discussion.
The CNS guidelines basically indicate that schwannomas must all come from peripheral nerves and thus are not reportable when they are on the spinal cord. However, the COC Inquiry 18174 & 18068 states that schwannomas occasionally will develop inside the dura (intradural) on the spinal cord and would be reportable.
According to an expert consultant, schwannomas must be derived from Schwann cells which are not a part of the CNS. All schwannomas come from peripheral nerves. Benign and borderline tumors of the peripheral nerves (C47_), including peripheral nerves along the spinal cord, are not reportable.
Reportability--Hematopoietic, NOS: If the bone marrow biopsy diagnosis is not reportable and cytogenetics studies indicate no clonal abnormality, is a case reportable if only the flow cytometry results show a "small monoclonal B-lymphocyte population consistent with a lymphoid component of a lymphoplasmacytic lymphoma or Waldenstrom macroglobulinemia"? See Discussion.
Bone marrow bx final diagnosis: Markedly hypercellular marrow consisting primarily of erythroid hyperplasia and, also, diffusely distributed small lymphocytes. Addendum comment: Flow cytometry demonstrated a small monoclonal B-lymphocyte population consistent with a lymphoid component of a lymphoplasmacytic lymphoma or Waldenstrom's Macroglobulinemia. Addendum comment: Cytogenetic analysis states no clonal abnormality was apparent. Normal female karyotype.
Question 1: Is this case reportable, and if so, what histology?
Question 2: Is there a hierarchy when flow cytometry and cytogenetics are done, but do not agree?
For cases diagnosed prior to 1/1/2010:This case is not reportable at this point. A lymphoid component is not equivalent to a diagnosis of a reportable disease. In order to be a malignant, reportable disease, the condition must be monoclonal and irreversible. Cytogenetics were negative for malignancy (i.e. no monoclonal abnormality identified which is the criteria used to establish this diagnosis). Use all information available when determining reportability.
For cases diagnosed 1/1/10 and later, 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/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.
Reportability/Ambiguous Terminology--Esophagus: Is a case with a biopsy diagnosis of "... focal areas suspicious for adenocarcinoma in situ change" reportable if the diagnosis on the partial esophagectomy specimen only includes the phrase "... with foci of high grade dysplasia; no invasive carcinoma identified"?
The case is not reportable.
The biopsy with a suspicious result (suspicious for adenocarcinoma) was disproven by the esophagectomy.
MP/H Rules/Histology: In the absence of a tissue diagnosis, should the histology field be coded based on the findings of a suspicious cytology or a CT scan that clinically confirmed the diagnosis? See Discussion.
Cytology (brushings at ERCP) which are highly suspicious of adenocarcinoma. A CT of the abdomen performed the next day shows a mass, most likely Klatskin tumor. Can the histology be coded to Klatskin tumor [8162/3] based on the CT findings?
For cases diagnosed 2007 or later, code the histology to 8162/3 [Klatskin tumor] using the histology from the CT. This case is confirmed clinically based on the CT. It cannot be accessioned based on suspicious cytology.
Rule H8 in the 2007 Histology Coding Rules for Other Sites provides instructions for coding histology when the pathology report and cytology report are not available.
Reporting Source: If the only patient record available for a physician office biopsy is the pathology report identified from a freestanding laboratory, is reporting source coded to 3 [Laboratory Only (hospital-affiliated or independent)] or 4 [Physicians office/Private Medical Practitioner (LMD)]? See Discussion.
A case was identified through a pathology report from a freestanding lab. The doctor who submitted the specimen left the state. His records cannot be located. Because the patient had the specimen removed at a physician's office, not at a path lab, is Type of Reporting Source field coded to the physicians office?
Reporting Source is the source that provided the best information used to abstract the case.
For this case, assign code 3 [Laboratory Only (hospital-affiliated or independent)]. Reporting source should reflect the lab where this case was identified. The MD office added nothing to the case, not even a confirmation of malignancy.
CS Tumor Size/CS Extension--Prostate: Because prostatectomy results are excluded from the CS Extension field for prostate, is code 95 [No evidence of primary tumor] accurate to reflect bilateral lobe involvement of prostate cancer when it is incidentally found following a radical cystectomy for a bladder primary? Why must tumor size be 000 when the CS Extension code is 95?
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 prostate CS Extension to 99 [Extension unknown] and code CS Tumor Size according to the information available from the surgery.
CS Extension code 95 [No evidence of primary tumor] should be used only in that rare situation when the only evidence of disease is distant mets or lymph node involvement, no primary tumor found. That is why CS tumor Size must be 000 when CS Extension code 95 is used.
Surgery of Primary Site--Breast: Should code 51 (Modified radical mastectomy without removal of uninvolved contralateral breast) be used when a patient has excisional biopsy (22) and axillary dissection followed by a simple mastectomy without removal of uninvolved contralateral breast (41) as part of the first course of treatment?
Assign code 51 or 52 if a patient has an excisional biopsy and axillary dissection followed by a simple mastectomy during the first course of therapy. Code the cumulative result of the surgeries, which is a modified radical mastectomy in this case.
SEER collects only one surgery code per case. Code the most invasive, extensive or definitive surgery in Surgery of Primary Site.
Grade, Differentiation: How is grade coded for cases using the FNCLCC (Federation Nationale des Centres de Lutte Contre Ie Cancer) system? See Discussion.
Is FNCLCC a recognized system in the United States? Tongue was the primary site for the case we saw that used FNCLCC.
Do not code the data item Grade based on the FNCLCC grade. You may record the FNCLCC grade in a text field.
