Report Question ID Question Discussion Answer Year
20051021 Primary Site--Breast: If a patient has multifocal tumors all in the upper outer quadrant of the breast, is the primary site coded to C-504 because all of the tumors are in UOQ or would the site be coded to C509 to reflect the fact that multiple tumors exist? Code the primary site to C504 [Upper outer quadrant]. All disease is located in one quadrant, code that quadrant. When disease involves two or more quadrants and the point of origin cannot be determined, code C509 [Breast, NOS]. See 2004 SEER manual, page C-470 for instructions about invasive and in situ in different quadrants. 2005
20061080 Histology (Pre-2007): Is histology for an anorectal biopsy of "Cloacogenic carcinoma (squamous cell carcinoma with basaloid features)" coded to 8124/3 [Cloacogenic carcinoma] or 8083/3 [Basaloid squamous cell carcinoma]?

For tumors diagnosed prior to 2007:

Code histology to 8124/3 [Cloacogenic carcinoma]. These are squamous cell carcinomas of basaloid type that are found in the cloacogenic (transitional) zone of the anal canal.

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.

Reportability/Diagnostic Confirmation: If a physician signs a case out as "precancerous melanosis of the face" (8741/2) and there is no microscopic confirmation of the disease, is this a reportable clinical diagnosis?

This case is reportable because the diagnosis of precancerous melanosis was stated by a recognized medical practitioner. Precancerous melanosis meets the reportable diagnosis criteria (See 2007 SEER Manual page 1).

Assign diagnostic confirmation code 8 [clinical diagnosis only].

Set the appropriate override flag for the SEER edit.

20061081 Collaborative Staging--Lung: Given that the AJCC lung TNM is not applicable for a high grade sarcoma of this site, how do we code Collaborative Stage for this site/histo combination when the pathologist indicates a TNM stage of T2bN0M0=stage III, using AJCC Soft Tissue Sarcoma schema?

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.

Use the lung schema to code CS for sarcoma of the lung. Complete the CS information as best you can from the medical record WITHOUT using the TNM Soft Tissue Sarcoma staging form. Visceral sarcomas are specifically excluded from soft tissue sarcoma TNM staging and sarcomas are excluded from the TNM staging for lung.

Sarcoma is listed on the Histology Exclusion Table for lung. When a case is coded in Collaborative Staging and the histology is on the exclusion list, SEER Summary Stage 1977 and 2000 can be assigned. For these cases, TNM will not be calculated and displayed results will be "T NA N NA M NA and Stage Group NA".

20010109 Grade, Differentiation--All Sites: If the grade given for the primary site is from a provisional diagnosis and the grade given for a metastatic site is from a final diagnosis, should we follow the SEER rule that says to code the grade as stated in the final diagnosis (e.g., Provisional diagnosis: High grade papillary serous carcinoma of ovary. Final dx: poorly differentiated adenocarcinoma in a caval lymph node)? Code the Grade, Differentiation field to 4 [High grade] from the examination of the ovary (primary site). Do not code grade from a metastatic site. 2001
20100104 Grade--Heme & Lymphoid Neoplasms: Is the phrase "aberrant T-cell expression" enough to code the grade field to T-cell when the final diagnosis on the pathology report is "AML with aberrant T-cell antigen expression"? Yes. Code grade to 5 [T-cell]. The T cell receptor, or TCR, is a molecule found on the surface of T lymphocytes (or T cells). 2010
20100070 Histology--Heme & Lymphoid Neoplasms: How is this field coded for a follicular lymphoma, grade 2 of 3, predominantly nodular?

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Code histology to 9691/3 [Follicular lymphoma, grade 2]. Nodular lymphoma is an obsolete term once used to describe follicular lymphoma. (See Appendix A, Table A3)

SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms. Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx.

20081097 DCO/Systemic Treatment, Surgery Sequence: How does SEER want systemic treatment/surgery sequence coded for a DCO case?

Assign code 0 [No systemic therapy and/or surgical

treatment] as a default for DCO cases.

 2008
20021008 Surgery of Primary Site/Surgical Procedure of Other Site--Bladder: What codes are used to represent these fields for a deeply invasive bladder primary treated initially with a TURP (for suspected prostate extension that turns out to be pathologically negative) and a TURB that is subsequently treated with a cystoprostatectomy?

For cases diagnosed 1/1/2003 and after, code:

1. Surgery of Primary Site field to 60 [Radical cystectomy (male only)] because the cystoprostatectomy was the most extensive (definitive) surgery performed to the primary site.

2. Surgical Procedure of Other Site to 2 [Non-primary surgical procedure to other regional sites] based on the TURP.

 2002
20000259 Histology (Pre-2007): What code is used to represent the histology for a "malignant invasive gastrointestinal stromal tumor (GIST)"?

For tumors diagnosed 2001-2006: Malignant GIST is coded 8936/3.

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.
