20061124 | Reportability: Is a tumor reported as "neoplasm" or "neoplasia" per the pathology report, which is subsequently clinically referred to as "carcinoma" reportable? See Discussion. |
Example 1: Lung-Wedge resection and subsequent left lower lobe lobectomy showed papillary epithelial neoplasia. Tumor board and subsequent reports state "nonsmall cell carcinoma of lung." Example 2: Kidney-Partial nephrectomy showed epithelial neoplasm, clear cells with low grade cytology. Subsequent urology clinic notes state that path revealed clear cell renal carcinoma. 2004 SEER manual states that "cases clinically diagnosed are reportable. If the physician treats a patient for cancer in spite of the negative biopsy, accession the case." Do we also accession the case if primary site has been resected? Would diagnostic confirmation be coded 8 (clinical diagnosis only)? |
Accession the case and code Diagnostic Confirmation as 8 [clinical diagnosis only]. Accession a case with negative pathology when the clinician is aware of the negative pathology and continues to refer to the case as malignant. |

20061102 | Histology (Pre-2007)--Lung: How is a poorly differentiated non-small cell carcinoma with "squamoid differentiation" coded? | For tumors diagnosed prior to 2007:
Squamoid and squamous are synonymous. Squamoid is non-standard terminology. It means "squamous like" and is a synonym of squamous.
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. |

20061085 | 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. |

20061023 | Reportability--Skin: Is a pilomatrix carcinoma of the skin reportable if it is described as being a malignant diagnosis based on poor circumscription, infiltrative growth pattern, and focal abundant mitoses? | No. Pilomatrix carcinoma is not reportable to SEER. Please see page 1 of the 2004 SEER manual. Skin primaries with histology codes from 8090 to 8110 are not reportable. Pilomatrix carcinoma is coded 8110/3. | 2006 | |
|
20061137 | Reportability/Grade, Differentiation: Does the term "grade 0" refer to differentiation or does its use as a modifying phrase in the final diagnosis of "grade 0 immature teratoma" impact reportability? |
Regarding the term "grade 0" for an immature teratoma, determine whether the pathologist is using that term to describe the primary tumor or its implants. The term can be used to describe both situations. An immature teratoma (IT) may have grade 0 (benign) implants. Grade 0 implants may affect the prognosis and treatment, but the primary tumor (IT) would still be malignant and therefore reportable. If grade 0 pertains to the primary tumor (as opposed to implants) it is benign, and therefore not reportable. |

20061068 | 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. | 2006 | |
|
20061129 | Multiple Primaries (Pre-2007)--Head & Neck: How many primaries are abstracted if a patient has bilateral involvement of tonsils with the same histology (e.g. squamous cell carcinoma)? See Discussion. | Patient was initially found to have mass on right tonsil. Biopsy of right tonsil on June 16 showed invasive carcinoma, favor squamous cell. On July 17 patient underwent right neck dissection, radical resection of right tonsil tumor and left tonsillectomy. Right tonsil showed squamous cell carcinoma, poorly differentiated. Left tonsil showed squamous cell carcinoma, poorly differentiated. Microscopic report stated: Right tonsil: Invasion of deep peritonsillar tissue and skeletal muscle. Sections of left tonsil demonstrate squamous cell ca focally distributed in the tonsil, predominantly in situ, but with focal microscopic invasion. Path staged each tonsil specimen. Right tonsil was T2N1. Left tonsil was T1Nx. | For tumors diagnosed prior to 2007:
Code as two primaries. Squamous cell carcinoma diagnosed in both left and right tonsils are multiple primaries unless one is stated to be metastatic from the other.
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. |

20061039 | CS Tumor Size/CS Site Specific Factor--Breast: Should the tumor size be coded to 1.5 cm or 2.5 cm and SSF6 coded to 020 or 030 respectively for a tumor with invasive and in situ components described as being a 2.5 cm tumor with a "greater than" 1.5 cm invasive portion? See Discussion. | Should tumor size be coded to 1.5 cm and SSF6 coded to 020 [Invasive and in situ components present, size of invasive component stated and coded in CS Tumor Size] or should the tumor size be 2.5 cm with SSF6 coded to 030 [Invasive and in situ components present, size of entire tumor coded in CS Tumor Size because size of invasive component not stated and in situ described as minimal (less than 25%)]? | 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 CS tumor size 992 [stated as greater than 1 cm] and SSF6 code 020. The September 2006 revision to the CS Tumor Size table now lists the 992-995 range codes as "greater than ___ cm." It is better to code the invasive size than the entire size of the tumor. In the TNM mapping, this would more accurately portray the tumor as T1c rather than T2. |

20061079 | Histology--Lymphoma: Is histology for "large B-cell lymphoma evolving from extranodal marginal zone B-cell lymphoma" coded to 9680/3 [Malignant lymphoma, large B-cell, diffuse, NOS] or 9699/3 [Marginal zone B-cell lymphoma]? | For cases diagnosed prior to 1/1/2010: Code the histology as 9699 [marginal zone B-cell lymphoma]. Code the histology from the original diagnosis. For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ. |

20061008 | Histology (Pre-2007)--Corpus uteri: How is a polyp with "endometrial carcinosarcoma (Malignant Mixed Mullerian tumor), endometrial adenocarcinoma, and some areas of high grade spindle sarcoma" coded? See Discussion. | The path report for the TAH stated the endometrium contained an endometrial polyp measuring 6x3x3cm. Within the polyp there was endometrial carcinosarcoma (Malignant Mixed Mullerian tumor), endometrial adenocarcinoma, and some areas of high grade spindle sarcoma. There is no myometrial invasion by the tumor. (The Endometrial bx before surgery was positive for Malignant Mixed Mullerian tumor.) | For tumors diagnosed prior to 2007:
Assign code 8980 [Carcinosarcoma, NOS]. According to the WHO Classification of tumors, Malignant mullerian mixed tumor is a synonym for carcinosarcoma and carcinosarcoma is now the preferred terminology rather than malignant mixed Mullerian tumor. Carcinosarcoma has both malignant epithelial and mesenchymal components. The epithelial component is usually glandular (adenocarcinoma in this case). The mesenchymal component is usually sarcoma (as in this case).
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. |
