20020059 | Grade, Differentiation: Can a FIGO grade be coded in this field or is the FIGO grading system to be used only for EOD/Stage coding? |
This answer pertains to cases prior to 2014. For cases diagnosed 2014 and forward, see http://seer.cancer.gov/tools/grade/
Do not use FIGO grade to code differentiation.
FIGO grade is something completely different from FIGO stage. FIGO stage is used to code EOD. FIGO grade is based on the percentage of non-squamous (i.e., solid) portions of the tumor and corresponds roughly to a three grade differentiation system: grade I, well differentiated (=<5% solid component); grade II, moderately differentiated (>5 - 50% solid); and grade III, poorly differentiated (> 50% solid). SEER is evaluating whether the ICD-O-3 6th digit differentiation codes (four grade categories) accurately represent the FIGO grade. For the time being, do not code FIGO grade.
For a diagnosis that includes commonly used differentiation term with a FIGO grade, such as "Moderately differentiated, FIGO grade II," disregard the FIGO grade and code the Grade, Differentiation field according to the term "Moderately differentiated." |

20021144 | EOD-Extension--Colon: What code is used to represent this field for a mid-ascending colon primary that invades through muscularis propria and into subserosal fibroadipose tissue that also presents with a "separate serosal nodule" of carcinoma within cecum that is consistent with a tumor implant (cT3, N0, M1)? | For cases diagnosed 1998-2003:
Code the EOD-Extension field to 85 [Metastasis], because the nodule of carcinoma in the cecum is not contiguous with the mid-ascending primary colon tumor. |

20021015 | Ambiguous Terminology/Reportability: How should the expressions "suspicious for but not diagnostic of" and "suspicious for the possibility of early invasive adenocarcinoma" be interpreted for reportability? Would the interpretation be different depending on the primary site? | For reportability, interpret "suspicious for but not diagnostic of" as NOT diagnostic of cancer.
The phrase "suspicious for the possibility of early invasive adenocarcinoma" may indicate that the case is in situ. If no further information is available, this is not reportable.
The site of the cancer diagnosis does not change the interpretation. |

20021210 | Date of Diagnosis/Histology (Pre-2007)--Breast: When there is a delay between the clinical diagnosis of a malignancy and the surgical resection of the primary site, can the resection be used to code the date of diagnosis, extension, size of the primary tumor, and histology? See discussion. | For example, mammogram March 28th states "certainly represents malignancy." Nothing else done until November 1st when pt presents w/skin retraction on PE and bone mets. A mastectomy November 6th shows "ductal ca w/dermal lymphatic invasion and tumor measuring 3.5 cm."
How is the date of diagnosis, extension, tumor size & histology coded for this case? |
For tumors diagnosed prior to 2007:
Code the Date of Diagnosis to March. Code the Histology field to 8500/3 [Infiltrating duct carcinoma]. Histology can be upgraded from a clinical histology to a pathological histology anytime.
For cases diagnosed 1998-2003, in coding extension, you need to assess whether there has been progression of disease or not. If progression of disease is verified, do not code extension using the surgical information from November. Code the extension and tumor size based on the mammogram and physical examination at the time of the mammogram, if available.
If no progression of disease is verified, use surgical information to code extension and tumor size.
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. |

20021108 | Histology (Pre-2007)/Grade, Differentiation: What code is used to represent the histology of "well differentiated low grade lipoma-like liposarcoma (atypical lipoma)"? See discussion. | The pathologic microscopic description states, "Well differentiated lipoma-like liposarcoma, sometimes termed atypical lipoma. This tumor will behave in a low grade malignant fashion. Slow growing recurrences can be expected. Metastatic disease is very rare unless the tumor dedifferentiates." | For tumors diagnosed prior to 2007:
Code the Histology field to 8851/3 [Liposarcoma, well differentiated] and the Grade to 1 [Well differentiated]. This histology is reportable to SEER.
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. |

20021081 | Multiple Primaries (Pre-2007)--Melanoma: Many melanoma patients have multiple occurrences over time that are not called recurrent and often are even in the same skin subsite, some in situ only and others alternating between in situ and invasive. Should these multiple occurrences really be new primaries? |
For tumors diagnosed prior to 2007: Unless it is stated to be a RECURRENT or METASTATIC melanoma, record each melanoma as a separate primary when: 1. The occurrences are more than two months apart. 2. The fourth digit of the ICD-O topography code for skin [C44._] is different . 3. The first three digits of ICD-O-3 morphology code are different. 4. An in situ melanoma is followed by an invasive melanoma. 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. |

20021159 | Histology (Pre-2007)--Breast: What code is used to represent the histology "mucinous carcinoma with Paget disease"? | For tumors diagnosed prior to 2007:
Code the Histology field to 8480/3 [mucinous carcinoma]. This answer assumes the patient presented with a single tumor. There is no combination code that includes these two entities. According to the rules for Coding Complex Morphologic Diagnoses, it would appear that the case should be coded to 8540 [Paget disease] because it is the higher code. However, this combination of histologies represents an exception to that rule. The prognosis for mucinous carcinoma is worse than the prognosis for Paget disease. As a result, it would be more appropriate to the histology to mucinous 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. |

20021004 | Histology: What code is used to represent the histology for the abbreviation "ca"? See discussion. | The abbreviation "ca" results in inconsistency when coding histology by a group of coders. Many abbreviation guides list both cancer (8000/3) and carcinoma (8010/3) as definitions for "ca." Page 261 of the SEER Self Instructional Manual, Book 5 lists carcinoma as the definition for "ca."
Example: What histology is used for a case with a clinical diagnosis of "recently diagnosed uterine ca" with metastasis to the pelvic lymph nodes? |
For uterine primaries, code the abbreviation "ca" to 8010/3 [carcinoma, NOS].
When coding death certificate only (DCO) cases, if the site is coded to an unknown primary and no specific histology information is available other than the abbreviation "ca," interpret ca as cancer (8000/3) per NAACCR Procedure Guidelines for Registries, Series V; Resolving Death Clearance Issues, page V-15. |

20020044 | Terminology/EOD-Extension--Prostate: How does SEER define the prostatic "apex"? See discussion. |
Some pathologists define the prostatic apex as including the bottom third of the prostate whereas others regard only the bottom-most portion of the gland to be the apex. |
SEER defines the apex as being the bottom-most portion of the gland. Apex means "narrowest part," which in the prostate would be the bottom-most portion of the gland. |

20021200 | Date of Diagnosis: How do you code this field when the pathologic confirmation is delayed for 2 months because the clinician decides to "watch and see what happens" to a CT identified mass thought to be either a "metastasis from a previously diagnosed malignancy or a new primary"? | Code the Date of Diagnosis field to the date of the scan. This is the earliest date that a recognized medical practitioner said the patient had cancer. The diagnosis on the CT scan was a malignancy. The only question was whether the mass on the scan was metastatic or a primary. | 2002 |
