Government Funding Lapse
Because of a lapse in government funding, the information on this website may not be up to date, transactions submitted via the website may not be processed, and the agency may not be able to respond to inquiries until appropriations are enacted.

MP/H Rules--Breast: Is inflammatory breast cancer always one primary per lifetime? Or is a subsequent inflammatory breast cancer a second primary if diagnosed more than five years later?
For cases diagnosed 2007 or later, a diagnosis of inflammatory breast cancer more than five years after a previous diagnosis of inflammatory breast cancer is a separate (new) primary. See rule M5 in the Breast Multiple Primary Rules.
Scope of Regional Lymph Node Surgery--Breast: How should this field be coded when a mastectomy that removed 3 sentinel lymph nodes is later followed by an axillary lymph node dissection that removed 17 lymph nodes? Should all of the lymph node information be coded to this field, even though the Number of Regional Lymph Nodes Examined field will be coded to the number of lymph nodes from the most definitive surgery (17)?
For cases diagnosed 1/1/2003 and after: Yes, all of the lymph node information should be coded to the Scope of Regional Lymph Node Surgery field using code 7 [Sentinel node biopsy and code 3, 4, or 5 at different times].
The Number of Regional Lymph Nodes Examined field no longer exists for this time frame.
EOD-Extension--Lung: How do you code extension for a lung tumor described on bronchoscopy as "obstructing the RUL and intruding into the right bronchus intermedius. Small tumor nodules distally in midline of anterior trachea wall"?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 85 [Metastasis] because the tumor nodules are discontinuous from the primary tumor.
CS Lymph Nodes/CS Mets at DX--Ovary: How are the following lymph node regions/chains coded in the Collaborative Stage schema for ovary?
1. pericolonic
2. pelvic, NOS
3. mesenteric, NOS
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.Revised 7-17-09
Assign CS Lymph Nodes code 10 for involvement of pelvic lymph nodes, NOS.
Code involvement of pericolonic nodes or mesenteric nodes, NOS in CS lymph nodes.
Update to Current Manual/Neoadjuvant Therapy--Pancreas: How are the neoadjuvant items coded for a patient who has unresectable pancreatic cancer and starts chemotherapy but will be evaluated after X cycles to see if patient may become a surgical candidate?
Assign the neoadjuvant therapy data items as if the patient had neoadjuvant therapy. Neoadjuvant Therapy data item would be coded either code 1 or 2 depending on whether the chemotherapy was completed or not. In this case, they are a surgical candidate by having the chemotherapy with the plan from the beginning to evaluate the chemotherapy after X cycles to see if surgery can be performed. After the patient is evaluated, update the abstract as needed.
Multiple Primaries--Hematopoietic, NOS: When the SEER Single versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table indicates that a disease is not a new primary, but a pathologist or clinician states that it is a new primary, do we use the physician information or the table?
For cases diagnosed prior to 1/1/2010:If the physician clearly states that this is a new primary, submit it as a new primary. Otherwise, use the Single versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table.
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.
EOD-Extension/EOD-Lymph Nodes--Bladder: Are "perivesical nodules" coded in the EOD-Lymph Nodes field or are they discontinuous extension and coded in the EOD-Extension field?
For cases diagnosed 1998-2003:
Code "perivesical nodules" in the EOD-Lymph Nodes field as involvement of regional lymph nodes. Each gross nodule of metastatic carcinoma in the fat surrounding an organ is counted as one positive regional lymph node.
Histology--Heme & Lymphoid Neoplasms: How is the histology coded for a "cutaneous diffuse large B-cell lymphoma, leg type" that has been verified as a valid diagnosis with prognostic factors including age and number of lesions on the legs?
Code this histology to 9680/3 [diffuse large B-cell lymphoma]. Primary cutaneous DLBCL, leg type, is listed as an Alternate Name for DLBCL per the Heme DB.
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.
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.
