Report Question ID Question Discussion Answer Year
20071069 First Course Treatment--Melanoma: How and where is the excision for an in-transit metastasis coded if the in-transit metastasis is coded in CS Lymph Nodes? See Discussion. Excision of skin of scalp nodule reveals in transit metastasis of melanoma. Patient also has lung metastasis and begins systemic treatment. No primary tumor identified. Code the excision in Surgical Procedure of Other Site because no primary tumor was identified. 2007
20071056 Reportability/Terminology--Prostate: Is the diagnosis of "atypical glands suspicious for adenocarcinoma" sufficient to report a prostate cancer if a note states that there is "insufficient atypia to establish a definitive diagnosis of malignancy"? See Discussion.

Date of report is July 2005. One positive specimen of 12.

Specimen 6: Diagnosis = Prostate tissue with a small focus of atypical glands suspicious for adenocarcinoma. Note. There is insufficient cytologic and/or architectural atypia to establish a definitive diagnosis of malignancy. Negative basal cell staining with cytokeratin... in atypical glands is consistent with the diagnosis of suspicious for adenocarcinoma. In addition, the diagnosis is suppported by a positive staining for alpha-methyl COA racemase (P504S), a recently discovered marker that is preferentially expressed in prostate cancer...

This case is reportable. The diagnosis states "suspicious for adenocarcinoma." "Suspicious for" is a reportable ambiguous term.

The additional stains supported this "suspicious" diagnosis. A more definitive diagnosis could not be made based on this specimen.

20071042 MP/H Rules/Multiple Primaries--Breast: How many primaries are to be abstracted when two tumors occur in one breast and both are ductal with the smaller tumor representing tubular carcinoma [variant]? See Discussion.

Right breast partial excision: Two invasive foci, one measuring 0.2cm and the second measuring 0.5cm. Both lesions are ductal carcinoma with the smaller representing tubular carcinoma (variant).

The breast histology table does not list tubular as a type of ductal, however, the pathologist states ductal carcinoma, tubular variant.

 For cases diagnosed 2007 or later, this is two primaries of the right breast, using the 2007 MP/H rules. For the purposes of the 2007 rules, tubular is not a specific type of duct. Duct carcinoma (8500) and tubular carcinoma (8211) are different at the second digit of the histology code. Rule M12 applies, making these separate primaries. 2007
20071062 Primary Site: For malignant gastrointestinal tumors (GISTs), how should the primary site be coded and which Collaborative Stage and TNM staging schemes should be used for disease found in the stomach, small intestine or other locations?

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 the primary site to the location where the GIST originated. If the primary site cannot be determined, assign code C809 [Unknown primary site].

GIST of gastrointestinal hollow viscera cannot be staged in TNM.

In Collaborative Staging, use the stomach scheme for GIST of the stomach. Use the small intestine scheme for GIST of the small intestine. For GIST of other primary sites, use the CS scheme for the specific site.

20071067 CS Extension/Histology (Pre-2007)--Bladder: Is the histology coded to 8010/2 [carcinoma in situ] or to 8130/2 [papillary transitional cell carcinoma, non-invasive] for a 2006 bladder tumor with a final path diagnosis of "mixed non-invasive papillary TCC and flat carcinoma in-situ" and is CS Extension coded to 01 [Papillary transitional cell carcinoma state to be noninvasive]or to 06 [Carcinoma in situ]? See Discussion. If the correct code for histology is 8130/2 and CS Extension is 06, this combination does not pass NAACCR edits.

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 prior to 2007, code CS Extension to 06 and histology to 8130/2. Override the NAACCR edit.

For cases diagnosed 2007-2014, 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.

 2007
20071108 MP/H Rules--Ovary: Rule M7 states bilateral epithelial tumors (8000-8799) are reportable as a single primary. Are bilateral germ cell tumors of the ovary (e.g., dysgerminoma (9060/3)) that occur simultaneously now reported as two primaries? For cases diagnosed 2007 or later, rule M7 applies to ovarian epithelial tumors with ICD-O-3 histology codes between 8000 and 8799. Rule M7 does not apply to dysgerminoma which is coded to 9060. Go on to the next rule, M8 and abstract as multiple primaries, left and right. 2007
20071105 Multiple Primaries/Histology--Lymphoma/Leukemia: How many primaries and what histologies are coded when a path diagnosis for a cervical/neck mass demonstrates classical Hodgkin's lymphoma on a background of chronic lymphocytic leukemia?

For cases diagnosed prior to 1/1/2010:Hodgkin disease and chronic lymphocytic leukemia are separate primaries according to our current instructions. Abstract and code them separately.

For cases diagnosed 1/1/10 and later, 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.

MP/H Rules--Bladder: Does rule M6 mean that any combination of tumors with the histologies 8050, 8120-8124, or 8130-8131 are the same primary regardless of the amount of time between tumor occurrences? See Discussion.

Many interpret Rule M7 to mean when separate occurrences of TCC of the bladder are diagnosed more than 3 years apart, it is reportable as a second primary. However, doesn't Rule M6 mean that if the histology is any combination of 8050, 8120-8124 or 8130-8131 for tumors diagnosed more than 3 years apart, they are reported as a single primary?

For cases diagnosed 2007 or later:

Papillary, transitional cell and/or papillary transitional cell carcinomas of the bladder are a single primary using Rule M6. Rule M6 includes diagnoses within 3 years of each other AND diagnoses more than three years apart for the histologies listed. If rule M6 applies to your case, stop. Do not continue on to Rule M7.

CS Tumor Size: Is a measured "area" equivalent to a tumor, mass or lesion size? See Discussion.

Collaborative Stage manual, page 26

Rule 4a: "always code size of the primary tumor, not size of the polyp, ulcer, cyst or distant metastasis."

Rule 4e: Additional rule for breast primaries: Example: Duct carcinoma in situ covering a 1.9 cm area with focal areas of invasive ductal carcinoma. Record the tumor size as 1.9 cm.

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.In general, a measured area is not equivalent to a tumor size.

Do not apply the rule related to the breast example to other primary sites. This example in the CS manual pertains to coding tumor size for breast primaries when the size of the invasive component is not stated. In the example, the area involved with duct carcinoma in situ is the only measurement available. The size of the invasive component was not given.

20071114 Ambiguous Terminology/Date of Diagnosis: How would you code the diagnosis date when the body of an imaging report uses reportable ambiguous terminology while the final impression in that same report uses non-reportable ambiguous terminology? Would you code the diagnosis date to the date of the scan or to the subsequent biopsy date that confirmed a malignancy? See Discussion. Within the body of a mammogram report, the radiologist stated, "diffuse inflammatory tissue throughout the rt breast w/ large rt axillary lymph nodes, consistent with an inflammatory carcinoma of rt breast." His final impression, however, said "extremely suspicious rt breast w/ extremely dense breast parenchyma and adenopathy in axilla, suggesting an inflammatory carcinoma." The patient then went on to have a biopsy, which was indeed positive for cancer.

Accept the reportable ambiguous terminology from the body of the mammogram. Record the date of the mammogram as the date of diagnosis.

The guidelines on page 4 of the 2007 SEER manual addressing discrepancies within the medical record can be applied to discrepancies within one report.

The instructions are:

If one section of the medical record(s) uses a reportable term such as

apparently and another section of the medical record(s) uses a term that is not on the reportable list, accept the reportable term and accession the case.
