20110105 Multiple primaries/Histology--Heme & Lymphoid Neoplasms: How many primaries should be reported for a bone marrow biopsy diagnosis of "lymphoproliferative disorder, small cell lymphocytic lymphoma/small cell lymphocytic leukemia consistent with marginal zone lymphoma"? According to our hematopoietic/lymphoid neoplasm physician expert, abstract one primary with the histology code 9699/3 [marginal zone lymphoma]. The pathologist is using the expression "small lymphocytic lymphoma" in a descriptive manner (marginal zone lymphoma is comprised of small lymphocytes) rather than in a "diagnostic" manner. 2011
20081096 Computed Ethnicity: Should the Name--Alias field be used when generating Computed Ethnicity? No, "Alias" is not used and should not be used to generate Computed Ethnicity. Computed Ethnicity records the ethnicity based on last name and/or maiden name using a computer algorithm. Alias is not part of the algorithm. 2008
20031091 EOD-Pathologic Extension--Prostate/Lymphoma: How is this field coded for a prostatic lymphoma? For cases diagnosed 1998-2003: Do not code the prostate pathologic extent of disease field for prostatic lymphoma. Leave the path extension for prostate field blank. Code the extent of disease using the lymphoma scheme. Use ONLY the lymphoma scheme - do NOT try to code both lymphoma and prostate extension fields for prostatic lymphoma. 2003
20041054 CS Extension--Prostate: For a tumor that is clinically inapparent, but a biopsy from the prostatic apex is positive, is this field coded to 15 [Tumor identified by needle biopsy, e.g., for elevated PSA (clinically inapparent)]?

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.

Yes. Code CS Extension-Clinical Extension to 15 [Tumor identified by needle biopsy, e.g., for elevated PSA (clinically inapparent)] for clinically inapparent prostate cancer with positive apex biopsy.

20061010 Multiple Primaries/Histology--Lymphoma: If an oral mucosa, right hard palate biopsy contains a composite lymphoma [low-grade follicular + chronic lymphocytic leukemia], how many tumors should be abstracted and how should the histology field(s) be coded?

For cases diagnosed prior to 1/1/2010:This is one primary. Assign code 9590 [Malignant lymphoma, NOS]. This is a composite lymphoma. Code to lymphoma when there is any solid tumor (in lymph nodes, tissue, etc.) Code to lymphoma, NOS since this is not purely follicular and there is no code for composite lymphoma.

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.

20031172 Hormone Therapy--Breast: Should hormonal therapy be coded as administered, when the physician states "Tamioxifen was given as a prescription?" Yes, based on the prescription for Tamoxifen, code Hormone Therapy as administered. 2003
20051082 2004 SEER Manual Errata/Grade--Colon/Bones: Is the term "pleomorphic" used to code tumor grade to 3 for selected primaries? Delete the row containing the word "pleomorphic" from the tables on pages 93, C-219 and C-411. This correction will be included in the next set of replacement pages for the 2004 SEER manual. 2005
20081028 Multiplicity Counter--Ill-defined sites: How is this field coded for Ill-Defined sites (C760-C768)? Code the number of tumors present if known. If the number of tumors present is not known, code 99 [unknown number of tumors, unknown if multiple tumors]. 2008
20140068

Surgery of Primary Site--Corpus uteri: What is the correct surgery code to assign for dilation and curettage (D&C) for an in-situ endometrium (C541) primary? The code to use for the cervix uteri (C530-C539) is specified, but not for the corpus uteri (C540-C549).

Assign code 20 for endometrial D&C for in situ cancer of endometrium.

20041081 Reporting Source: Is an ER patient who is diagnosed on peripheral smear with an acute leukemia coded as an outpatient if the patient died while in the process of being admitted for treatment or is the patient coded as a death certificate case? Code reporting source as 1 [Hospital Inpatient/Outpatient or Clinic] for the case above. This case will be abstracted using information from the outpatient/ER record (and the death certificate). 2004
