20041021 | Histology (Pre-2007)--Corpus Uteri: How should this field be coded when the D&C which shows "adenocarcinoma with mucinous and papillary features" and the TAH demonstrates only "endometroid carcinoma"? See Discussion. | Should Histology be coded to 8380 [endometroid adenocarcinoma] because it is the most representative sample or to 8323 [mixed cell adenocarcinoma], per the Complex Morphology Coding Guidelines? The instructions in the Guidelines seem to imply that it is most important to represent combination histologies first, with majority (most representative sample) of tumor having a lower priority. | For tumors diagnosed prior to 2007:
Code Histology based on the pathology report from the most representative tissue. For the example above, code Histology to 8380 [Endometroid adenocarcinoma] based on the TAH/BSO pathology report.
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. |

20041071 | Histology (Pre-2007)--Breast: When the histology from a lumpectomy differs from that of a core needle biopsy, should the lumpectomy histology be coded? See Discussion. | Histology - Page 85 of the SPM 2004, Histology Type Coding Instructions, #2. Use the histology stated in the final diagnosis from the pathology report. Use the pathology from the procedure that resected the majority of the primary tumor. Based on this rule, should the following case should be coded to Ductal Carcinoma (8500/31)? Core needle bx: WD Infiltrating Ductal Carcinoma with focal lobular features. Lumpectomy: WD Invasive Ductal Carcinoma. |
For tumors diagnosed prior to 2007:
Yes, code this case to 8500/31 [Well differentiated invasive ductal carcinoma]. Code the histology stated on the pathology report from the procedure removing the most tumor tissue. A lumpectomy will usually provide more tumor tissue than a core needle biopsy. First, determine which specimen contains the most TUMOR tissue -- in this case the lumpectomy. Next, apply the histology coding rules to the diagnosis on that pathology report. The rationale is that a diagnosis from a smaller specimen will be less accurate and less representative of the true histology compared to a larger tumor specimen.
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. |

20041037 | Multiple Primaries (Pre-2007)/Histology (Pre-2007)/Grade, Differentiation--Thyroid: How many primaries, with what histologies should be coded when a thyroidectomy reveals "anaplastic carcinoma" and "papillary carcinoma" occurring as two separate tumors? See Discussion. | Example: Thyroidectomy revealed anaplastic carcinoma of the thyroid with mets to lymph nodes. The path report stated that the thyroid specimen also contained a small papillary carcinoma. Differentiation for the papillary carcinoma was not stated. | For tumors diagnosed prior to 2007:
Accession and code as two thyroid primaries: Anaplastic carcinoma [8021/34] Papillary carcinoma [8260/39]
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. |

20041043 | First Course Cancer-Directed Treatment--Bladder: How should Mitomycin-C instillation for bladder cancer be coded? | Code the instillation of Mitomycin-C into the bladder for a bladder primary in both the Chemotherapy and Surgery to Primary Site fields. Code the Chemotherapy field to 02 [Single-agent chemotherapy administered as first course therapy]. Mitomycin-C is listed in SEER book 8 as a chemotherapeutic drug, specifically an alkylating agent.
Also, code the Surgery of Primary Site field to 15 [intravesical therapy]. Code the surgical procedure as well as the type of drug (chemotherapy in this case). |

20041022 | Primary site/Histology (Pre-2007)/Behavior: What is the correct site and histology/behavior for the following diagnosis: "mucinous cystadenoma of the appendix with perforation and pseudomyxoma peritonei." This was diagnosed at e-lap for a separate adenocarcinoma of the ascending colon. | For tumors diagnosed prior to 2007:
The appropriate code for mucinous cystadenoma of the appendix with perforation and pseudomyxoma peritonei is C18.1 8470/0. It is not reportable to SEER. According to our pathologist consultant, mucinous cystadenoma is a legitimate term for such appendiceal tumors. They may implant all over the peritoneum as pseudomyxoma peritonei, especially in the face of perforation, without being histologically malignant.
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. |

20041063 | Primary Site/Histology (Pre-2007)--Mediastinum: How do we code these fields for a case described as a "neuroendocrine carcinoma" of the "anterior mediastinum" without failing the SEER "impossible" site/histology combination edit? See Discussion. | Two different facilities state that the patient has "neuroendocrine carcinoma of the anterior mediastinum." This coded combination failed SEER edit (SEERIF38). We can not correct it because that edit flag does not appear on our system. Both facilities indicate that the mediastinum is the primary. In addition, there is text to support both the histology and primary site codes. | For tumors diagnosed prior to 2007:
The combination of C381 [anterior mediastinum] and 8246 [neuroendocrine carcinoma] will be removed from the list of "impossible" site/histology combinations. There are rare cases of neuroendocrine carcinoma of the anterior mediastinum. As illustrated in the discussion, verify that the primary site is anterior mediastinum, the histology is neuroendocrine ca, and document those findings in the text.
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. |

20041013 | Primary Site--Ovary/Peritoneum: Should this field be coded to ovary or peritoneum when the bulk of the tumor is in the peritoneum and there is only surface involvement of the ovary? | If it is not clear where the tumor originated, use the following criteria to distinguish ovarian primaries from peritoneal primaries. The primary site is probably ovarian, unless: --Ovaries have been previously removed --Ovaries are not involved (negative) --Ovaries have no area of involvement greater than 5mm. Descriptions such as "bulky mass," "omental caking" probably indicate an ovarian primary. Descriptions such as "seeding," "studding," "salting" probably indicate a peritoneal primary. |

20041016 | CS Site Specific Factor 4--Prostate: If PAP is not mentioned in the chart, should Site Specific Factor 4 be coded to 999 [unknown or no information] or 000 [test not done]? | 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 tumors diagnosed 2004 only:
Code the CS Site Specific Factor 4 to 999 [Unknown or no information; Not documented in patient record]. If there is no report of a lab test in the health record, code as 999.
Code this field to 000 [Test not done] when there is a statement in the record that a test was not performed.
Tumors diagnosed 1/1/2005 forward no longer have PAP coded in the Site Specific Factor 4 field. |

20041012 | Multiple Primaries (Pre-2007)--Colon: What is the number of primaries for a case of familial polyposis with at least three separate tumors having invasive adenocarcinoma, one in the rectum? See Discussion. | A patient had a total proctocolectomy and was found to have familial polyposis. At least 3 separate tumors were identified with invasive adenocarcinoma, one of which was in the rectum. Is this 2 primaries: C18.9 with 8220/3 and C20.9 with 8140/3 or is this all one primary cancer? | For tumors diagnosed prior to 2007:
Familial polyposis is always a single primary. Code the primary site for the case example above to C199 [colon and rectum].
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. |

20041072 | Histology (Pre-2007)--Colon: Must a case be specifically labeled "familial adenomatous polyposis" or is the mere presence of numerous/multiple polyps sufficient for coding the histology to FAP? | For tumors diagnosed prior to 2007:
The presence of numerous/multiple polyps is not necessarily adenomatous polyposis coli. Adenomatous polyposis is an extreme condition usually characterized by the presence of hundreds of polyps and should be identified as such either clinically or pathologically. Look for the term "Familial adenomatous polyposis," FAP or one of its synonyms: Adenomatosis of the colon and rectum [ACR] Familial adenomatous colon polyposis Familial colonic polyposis Multiple familial polyposis In the absence of these terms, the following probably indicate a diagnosis of FAP: Hundreds of adenomatous polyps throughout large intestines, and at times, throughout the digestive system Development of polyps as early as ten years of age, but more commonly at puberty History of colectomy
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. |
