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.
Reportability: Is an AIN III that arises in perianal skin, skin tags or condyloma acuminatum reportable or must an AIN III arise in the anus or anal canal in order to be reportable?
AIN III arising in perianal skin [C445] is not reportable.
AIN III [8077/2] of the anus or anal canal is reportable.
Chemotherapy: If a physician does not document the reason chemotherapy was given concurrently with radiation therapy, should it be assumed to have been used as a radiosensitizer or radioprotectant and then, per SEER chemotherapy coding instruction 2, ignore coding the chemo agent as treatment?
Do not assume that a chemo agent given with radiation therapy is a radiosensitizer. Seek additional information.
Compare the dose given to the dose normally given for treatment. When chemotherapeutic agents are used as radiosensitizers or radioprotectants, they are given at a much lower dose.
CS Site Specific Factor--Prostate: Can autopsy results also be used when coding SSF3, pathologic extension, given that the instructions only address the use of prostatectomy findings when coding this field?
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 prostate cancer was diagnosed on autopsy, or the autopsy was performed within the staging timeframe (See 2004 SEER Manual, page 112), code SSF3 using the autopsy information.
Primary Site--Unknown & ill-defined site: Should the primary site be coded to C809 [Unknown primary site] or C761 [Thorax, NOS] if the patient died following a limited work-up that included on a cytology on pericardial fluid that was positive for poor differentiated adenocarcinoma?
Based on the information provided, code the primary site to C809 [Unknown primary site]. There is not enough information provided to suggest that the primary site is the thorax or any other location.
CS Tumor Size--Lung/Breast: Explain why the SEER instructions differ from the CS Manual regarding priority order of sources to code tumor size? See Discussion.
Regarding the 2004 SEER Manual, Appendix C, Site Specific Coding Modules, Lung and Breast. The priority of sources for coding tumor size is Pathology, Operative Report, PE, imaging for breast and pathology, operative, endoscopic, and imaging for lung. This differs from the CS Manual instructions.
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.For cases diagnosed in 2007 and forward, follow the instructions in the 2007 SEER manual and the CS manual.
CS Extension/CS Mets at Dx--Corpus uteri: Is a microscopic metastasis in a cul-de-sac implant more appropriately reflected in the CS Extension field code 80 [Further contiguous extension; cul-de-sac] or in the CS Mets at Dx field code 40 [Distant metastasis]?
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.Assign code 80 [Further contiguous extension; Cul de sac] for CS extension in this case. Endometrium and ovary are exceptions to the rules that only contiguous extension is coded in Extension code 80. Only true distant metastases are coded in Mets at Dx.
Ambiguous Terminology--Breast: Is a stereotactic biopsy that is "focally suspicious for DCIS" reportable if it is followed by a negative excisional biopsy? See Discussion.
Per the 2004 SEER manual page 4, 1.a, the case is reportable based on the ambiguous term "suspicious" for DCIS.
Per the 2004 SEER manual page 4, 1.c, use these terms when screening diagnoses on pathology reports, operative reports, scans, mammograms, and other diagnostic testing other than tumor markers.
Note: If the ambiguous diagnosis is proven to be not reportable by biopsy, cytology, or physician's statement, do not accession the case.
Do not accession this case. The needle localization excisional biopsy was performed to further evaluate the suspicious finding found on stereotactic biopsy. The suspicious diagnosis was proven to be false.
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.
