Report Question ID Question Discussion Answer Year
20021137 Multiple Primaries (Pre-2007)--Soft Tissue: Does SEER agree that one primary of the soft tissues of pelvis [C49.5] should be reported when a pathologic diagnosis for bilateral herniorrhaphies is "right and left inguinal hernias with low grade spindle cell sarcoma"?

For tumors diagnosed prior to 2007:

Yes. This is one primary and should be coded to C49.5 [Connective, subcutaneous and other soft tissue of pelvis]. According to Rule A in ICD-O-3, the type of tumor ("sarcoma") indicates origin from a particular tissue, resulting in the primary site code of C49.5 [Inguinal region, NOS] for this sarcoma.

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.

20021138 Grade, Differentiation--All Sites: What code is used to represent this field when a pathology report describes a tumor as a low grade neoplasm consistent with a specific histologic type (e.g., Low grade neoplasm consistent with carcinoid)? Code the Grade, Differentiation field to 2 [Low grade]. 2002
20021002 Histology (Pre-2007)--Breast: What code is used to represent the histology "ductal carcinoma in situ with comedo necrosis"? See discussion.

SEER distributed breast questions to the Advisory Group made up of pathologists from different SEER regions. One question dealt with the terms comedo type, comedo necrosis and comedocarcinoma. Per the Advisory Group, "Do not code comedo necrosis. These three phrases each represent a different level of diagnosis and can't be compared. "Comedocarcinoma" is an established diagnosis of in situ carcinoma and should be coded as such. "Comedo type" refers to a type of intraductal cancer; whether it is considered to be a true diagnosis is probably still equivocal. "Comedo necrosis" refers to a description of cellular pathological events that occasionally occur within an intraductal tumor of comedo type, which should not be coded at all."

Per the SEER preferred answer: Comedo type = comedocarcinoma. Ignore comedo necrosis.

For tumors diagnosed prior to 2007:

Code the Histology field to 8500/2 [ductal carcinoma in situ].

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.

 2002
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.

Multiple Primaries (Pre-2007)--Ovary: Are mucinous cystic tumors of low malignant potential diagnosed in the left ovary in 12/2000 and in the right ovary in 7/2001 reportable as two primaries? See discussion.

Page 14 of the SEER Program Code Manual, 3rd Edition, states that bilateral retinoblastomas and bilateral Wilms tumor are always single primaries whether simultaneous or not. Does this apply to bilateral ovarian tumors as well?

For cases diagnosed 2001-2006:

Borderline tumors are not reportable to SEER as of 2001. If you are collecting them in your registry, use the following procedure: Exception 1 in the SEER Program Code Manual, 3rd Edition, responds to the issue of processing ovarian tumors. Simultaneously occurring ovarian tumors with a single histology are coded as one primary. In the case you cite, the right ovary primary occurred 7 months after the left ovary primary. This is not simultaneous, so it would be counted as a second primary.

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.

EOD-Size of Primary Tumor/EOD-Extension--Breast: How do you code extension when the tumor in the breast is in situ and the regional axillary lymph nodes are positive? See discussion.

For example, what extension code is used for a 4.5 cm DCIS (no invasive ca found in excisional biopsy or mastectomy specimen) with mets to 01/07 LNs?

For cases diagnosed 1998-2003:

Code the EOD-Size of Primary Tumor field to 045 [4.5 cm]. Document how the size was determined in the EOD-Extension field.

Code the EOD-Extension field to 16 [Invasive and in situ components present, size of entire tumor coded in Tumor Size (size of invasive component not stated) AND proportions of in situ and invasive not known]. By virtue of the lymph node metastasis, this must be an invasive breast carcinoma. The size of the invasive component is unknown.

 2002
20021045 Histology/Grade, Differentiation--Lymphoma: What code is used to represent the histology "high grade malignant lymphoma with features of so called blastic NK cell cutaneous lymphoma [hematodermic lymphoma]" found on punch biopsy?

For cases diagnosed prior to 1/1/2010:Code the Histology field to 9709/3 [cutaneous lymphoma, NOS]. Code the Grade, Differentiation field to 8 [NK cell].

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.

20021105 Grade, Differentiation: Do we code to the highest grade even when no grade is given at the time of initial diagnosis, but a grade is obtained on tissue removed after non-surgical treatment has occurred? See discussion.

1. In 2000 a pleural fluid aspirate had no grade. Pt treated with chemo. In 2000 a BSO diagnosed high grade papillary serous adenocarcinoma of the ovary.

2. In 1993 a prostate bx had no grade. Pt treated. In 2001 prostate bx revealed a Gleason's 4+3.

Code the grade at the time of initial diagnosis (if the specimen is from the primary site) or to the grade identified as part of a first course of cancer-directed surgery to the primary site. When different grades are specified for tissue pathologically reviewed from the primary site before and after treatment, code the higher grade. This is true even if the higher grade is obtained while the pt is still undergoing first course of cancer-directed therapy.

1. Code the Grade to 4 [high grade], if the grade information from the BSO specimen represents the grade associated with primary site surgical specimen. Even though the grade was obtained after first course of cancer-directed therapy started, it was obtained during first course of cancer-directed therapy.

2. Code the Grade to 9 [Cell type not determined, not stated or not applicable]. Grade was obtained well after the first course of cancer-directed therapy ended.

20021202 Primary Site--Head & Neck (Middle ear): How do you code site for a skull based tumor consistent with a low grade papillary adenocarcinoma of "endolymphatic sac origin"? Code Primary Site to C30.1 [Middle ear]. The endolymphatic sac is part of the inner ear labyrinth located with in the petrous portion of the temporal bone. 2002

Other Cancer Directed Therapy--Hematopoietic, NOS: Is "aspirin" treatment for primary polycythemia? See discussion.

Aspirin is listed as treatment for "thrombocythemia" in the Abstracting and Coding Guide for the Hematopoietic Diseases but not for "primary polycythemia."

Do not code aspirin as treatment for primary polycythemia (polycythemia vera).
