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--Brain: Is angiocentric glioma, WHO grade 1 of the right frontal lobe reportable? If so, how is histology to be coded?
Angiocentric glioma is reportable. The best histology code currently available is 9380/1 [glioma, NOS; uncertain behavior].
According to the WHO Classification of Central Nervous System Tumours, Angiocentric glioma has a behavior of /1. WHO defines it as an epilepsy-associated stable or slowly growing cerebral tumour primarily affecting children and young adults; histopathologicaly characterized by an angiocentric pattern of growth, monomorphous bipolar cells and features of ependymal differentiation.
MP/H Rules/Multiple Primaries: When the pathology report from a FNA or other biopsy states an "in situ" carcinoma and the patient waits more than 60 days for a more definitive procedure which documents an "invasive" carcinoma, is this reported as two primaries?
For cases diagnosed 2007 or later:
No. When the invasive component is discovered as part of the work-up phase leading to treatment decisions, the case should not be abstracted as a multiple primary. In the rare instance when a patient has not been treated and is still having diagnostic work-up greater than 60 days after the malignancy is diagnosed, do not count the invasive diagnosis as a new primary.
EOD-Clinical Extension/EOD-Lymph Nodes--Prostate: How do you code clinical extension and lymph nodes for path only prostate cases treated with a TURP? Would clinical extension be coded to unknown or localized, NOS?
For cases diagnosed 1998-2003: Code the EOD-Clinical Extension field to 30 [localized, NOS] and the EOD-Lymph Nodes field to 0 [no lymph node involvement]. Per Note 7: Use code 30 when there is insufficient information as to whether the tumor is clinically apparent or inapparent but the tumor is confined to the prostate. This is an example of a case where there is insufficient information as to whether the tumor is clinically apparent or inapparent. Assume the tumor is confined to the prostate.
CS Site Specific Factor--Colon: If the patient has a polypectomy followed by definitive surgery, can a higher CEA reported after the polypectomy but before the colon resection be 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.If the tumor was in the polyp, do not use the post-polypectomy CEA even if it is higher than CEA's prior to the polypectomy. In this situation, the polypectomy would be treatment.
Conversely, if this is a frank adenocarcinoma or the tumor was so invasive that the polyp removed only a portion, use the post-polypectomy CEA because the polypectomy would not be treatment in this situation.
MP/H Rules/Multiple Primaries--Bladder: The new multiple primary rule M7 states that tumors diagnosed more than three years apart are multiple primaries. Does this apply to in situ bladder tumors that occur more than three years apart and to an in situ tumor that occurs three years after an invasive tumor?
For cases diagnosed 2007 or later, use the MP/H rules in order. Rule M6 comes before rule M7.
M6 states that bladder tumors with certain histologies are a single primary. It is a single primary regardless of timing if there is any combination of:
papillary carcinoma [8050]
transitional cell carcinoma [8120-8124]
papillary transitional cell carcinoma [8130-8131]
Rule M7 applies to bladder tumors with histologies other than those listed above. If you have such a case, rule M7 applies to in-situ tumors and to an in situ three years after an invasive.
Reportability/Histology-Gallbladder: Is high grade biliary intraepithelial neoplasia of the gallbladder reportable?
High grade biliary intraepithelial neoplasia of the gallbladder is reportable. Assign code 8148/2. It is also known as biliary intraepithelial neoplasia grade 3, or BilIN-3.
Secondary polycythemia vera is not reportable. See Appendix F.
Primary polycythemia vera is a condition in which there is an overproduction of blood cells due to a neoplastic process. Secondary polycythemia vera is an over production of red blood cells caused by a co-morbidity, in this case, volume depletion.

Histology--Breast: Please confirm the morphology code for a diagnosis of "encapsulated papillary carcinoma" of the breast. Several articles on the internet lead me to believe it is the same as an intracystic carcinoma, code 8504/2 (our case shows no evidence of invasion).
You are correct in coding 8504/2 for this case. Per the 4th Edition WHO Tumors of the Breast, encapsulated papillary carcinoma (EPC) of the breast is synonymous with intracystic or encysted papillary carcinoma. It is a variant of ductal carcinoma in situ (DCIS).
Reason No Cancer-Directed Surgery--Hematopoietic, NOS: Is this field always coded to 1 [not performed, not part of first course] for leukemias & other hematopoietic diseases?
For cases diagnosed 2003 and later: For sites where "Surgery of the primary site" is coded 00 or 98 (hematopoietic included), Reason for No Surgery of Primary Site should be coded as 1 [Surgery of the primary site not performed because it was not part of the planned first course of treatment]. On rare occasions, there may be surgery to the primary site for a hematopoietic disease, such as an excisional biopsy of a myeloid sarcoma. Refer to the "Abstracting and Coding Guide for the Hematopoietic Diseases" for cell-type-specific treatment information.
