Laterality: Why is a code 5 for laterality midline only allowed for certain sites of brain and skin? I have a nasal cavity tumor and the path report specifically says "Tumor laterality: midline". What is the correct laterality code here?
Assign laterality code 9 for midline nasal cavity tumor. We will investigate this issue further.
Histology (Pre-2007)--Breast: Is histology coded from the more representative specimen or should the combination code 8522/3 [Infiltrating duct and lobular carcinoma] be used for a case in which a right breast mass needle core biopsy revealed infiltrating ductal ca, grade III and the subsequent right mastectomy revealed a 2.3 cm lobular carcinoma?
For tumors diagnosed prior to 2007:
Code the histology using the final diagnosis on the pathology report of the procedure that resected the majority of the primary tumor. In this case, the mastectomy removed more of the tumor than the needle biopsy. The final diagnosis from the mastectomy is infiltrating lobular carcinoma. Code histology to 8520/3 [lobular carcinoma].
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.
CS Tumor Size--Breast: Is the largest focus or the total area coded for tumor size in a patient presenting with "scattered foci of DCIS, largest focus measuring 0.6cm. DCIS spans a total area of 2.1cm."
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 the size of the largest focus in CS tumor size. Code the tumor size for this case as 006 (6mm or 0.6cm).
MP/H Rules/Histology--Thyroid: When is 8341/3, papillary microcarcinoma coded? The code description in ICD-O-3 is followed by (C739), yet there are two SINQ answers that tell us specifically to not use this code for thyroid primaries. Even the first revision of ICD-O-3 still carries the (C739) as part of this code, which goes against SINQ 20110027 and 20081127.
Per the WHO Tumors of Endocrine Organs, for thyroid primaries/cancer only, the term micropapillary does not refer to a specific histologic type. It means that the papillary portion of the tumor is minimal or occult (1cm or less in diameter) and was found incidentally. WHO does not recognize the code 8341 and classifies papillary microcarcinoma of the thyroid as a variant of papillary thyroid and thereby should be coded to 8260. If the primary is thyroid and the pathology states papillary microcarcinoma or micropapillary carcinoma, code 8260 is correct. This information will be included in the upcoming revisions to the MP/H manual.
EOD 2018/EOD Primary Tumor--Melanoma: The code and level translations in the Note 4 of Extent of Disease (EOD) Primary Tumor for Melanoma Skin seem incorrect. Please advise.
* Code 000: In situ
* Code 100: Level I (should be level II) (< 0.75 mm Breslow's Depth)
* Code 200: Level II (should be level III) (0.76 mm to 1.50 mm Breslow's Depth)
* Code 300: Level III (should be level IV) (> 1.50 mm Breslow's Depth)
Please see the corrected levels below for the note. Note 4: If a Breslow's depth is given in the pathology report and there is no other indication of involvement, the following guidelines may be used (Note: If a physician documents a different Clark's Level than provided by these guidelines, go with the physician's Clark Level)
Code 000: Level I (In situ)
Code 100: Level II (< 0.75 mm Breslow's Depth)
Code 200: Level III (0.76 mm to 1.50 mm Breslow's Depth)
MP/H Rules/Multiple Primaries: Is this counted as one or two primaries?
Patient is diagnosed with SCC esophageal cancer. Work-up reveals a lung nodule. Lung FNA (cytology) is read by the pathologist as SCC, favor metastatic esophageal SCC. However, the managing physicians are treating the patient as two separate primaries.
If the patient is being managed and treated as a case of primary lung cancer, report the lung diagnosis as a separate primary.
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/Immunotherapy--Prostate: Is XGEVA, given for bone mets from prostate cancer, abstracted as immunotherapy, or is it an ancillary drug and not recorded?
Do not record XGEVA when given for bone mets from prostate cancer. See SEER*Rx for more information.
Reportability--Heme & Lymphoid Neoplasms: Is the term "thrombocytopenia" equivalent to the term "refractory thrombocytopenia" and should be a subsequent primary if it follows a treated diagnosis of pancreatic cancer?
Thrombocytopenia NOS is not a reportable diagnosis per Appendix F. Thrombocytopenia and Refractory Thrombocytopenia are not the same disease.
Thrombocytopenia is caused by a decreased number of platelets in the blood. Non-malignant causes include disseminated intravascular coagulation (DIC), drug-induced non-immune thrombocytopenia, drug-induced immune thrombocytopenia, hypersplenism, immune thrombocytopenic purpura (ITP), thrombotic thrombocytopenic purpura, and infections of the bone marrow.

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.
