MP/H Rules--Corpus uteri: How is histology coded for an endometrial tumor described as an "endometrioid adenocarcinoma with prominent squamous metaplasia"?
For cases diagnosed 2007 or later:
Endometrioid adenocarcinoma with squamous metaplasia is coded 8570 [Adenocarcinoma with squamous metaplasia]. This falls under the Histology Coding Rules for Other Sites, rule H17. The code for Endometroid adenocarcinoma is 8380. The code for Adenocarcinoma with squamous metaplasia is 8570. The histology with the numerically higher ICD-O-3 code is Adenocarcinoma with squamous metaplasia -- 8570.
Surgery of Primary Site--Prostate: What treatment code is used to represent prostate carcinoma treated with "high intensity focused ultrasound" (HIFU)?
For cases diagnosed 1998 and later:
Code the Surgery of Primary Site field to 17 [Other method of local tumor destruction]. HIFU uses focused energy to destroy tissue. It is classified as a surgical procedure.
Reportability: Are malignant tumors of genital skin reportable? On page 1 of the 2004 SEER Manual, Reportable Diagnoses, 1.b.i. Exceptions: malignant and invasive histologies not required by SEER - Skin. There is no longer a note that states that lesions ARE reportable for skin of the genital sites. Has SEER discontinued the collection of malignant skin tumors of the genital sites OR is the manual in error?
The histologies listed in the exception on page 1 are NOT reportable when the topography code is C440-C449. The manual specifically lists the topography codes in 1.b.1. Diagnoses with the listed histologies ARE reportable when the topography code is NOT C440-C449. Genital skin sites are not coded C440-C449 so a note is not needed.
Race: How is race coded for a patient who self-reports as white? In the Family History portion of the genetics consult, it states the maternal family is of mixed European and Cherokee descent; the paternal side is of mixed German/mixed European descent. Is race coded as Race 1: 03-American Indian and Race 2: 01-White, or as 01-White according to self-report by the patient?
Self-reported information is the highest priority for coding race. That is because the race information for the U.S. population comes from census data and that information is self-reported. For national cancer statistics, in order for the numerator (cancer cases) and the denominator (population) to be comparable, use self-reported race information whenever it is available. We will add this clarification to the SEER manual.
Update to Current Manual/Neoadjuvant Treatment: What codes should be used for Neoadjuvant Therapy--Clinical Response and Neoadjuvant Therapy--Treatment Effect when the neoadjuvant therapy is still in progress at the time the case is initially abstracted as with rapid reporting. There is no code for neoadjuvant therapy still in progress and code 9 generates an edit for Neoadjuvant Therapy--Clinical Response.
Assign code 8 for Neoadjuvant Therapy--Clinical Response and assign a code 9 for Neoadjuvant Therapy--Treatment Effect when the treatment is still in progress. Revise these codes after the treatment has been completed.
We will update the manual to include these instructions.
First course treatment/Immunotherapy--Prostate: Is XGEVA, given for bone mets from prostate cancer, abstracted as immunotherapy, or is it an ancillary drug and not recorded?
Do not record XGEVA when given for bone mets from prostate cancer. See SEER*Rx for more information.
Reportability--Heme & Lymphoid Neoplasms: Is EBV-positive hemophagocytic lymphohistiocytosis (HLH) reportable when diagnosed in a 5 year old child and resulted in death in less than two months?
Hemophagocytic lymphohistiocytosis (HLH) is not a reportable disease because it is not listed in the Heme DB.
Per our expert pathologist consultant, "HLH is a lymphocyte driven hemophagocytic syndrome which may be either genetically based or caused by over-activated lymphoid cells, often in response to a viral infection. It is an abnormal immune response and is not considered a malignant disease, and is, therefore, not reportable. It is not synonymous with EBV-positive T-cell lymphoproliferative disease of childhood (9724/3)."
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.

EOD-Extension--Lymphoma: What code is used to represent this field for a lymphoma that involves the spleen and lymph nodes above the diaphragm (e.g., involvement of only the spleen below the diaphragm and cervical lymph nodes above the diaphragm)?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 32 [30 + involvement of the spleen; III S]. The spleen is counted twice (once as the spleen and a second time as a lymph node region below the diaphragm). As a result, the EOD-Extension field is coded to reflect involvement of lymph node regions on both sides of the diaphragm plus involvement of the spleen. See Note 1 on the EOD scheme that states "Any lymphatic structure is to be coded the same as a lymph node region."
Primary Site/Histology--Lymphoma: How are these fields coded when the final diagnosis per the pathology report is, "Soft tissue and skeletal muscle, left thigh--Large B cell lymphoma with polyclonal and mature t-cells, involving the soft tissue"?
For cases diagnosed prior to 1/1/2010:Site: C492 [Soft tissue thigh]
Histology: 9680/36 [T-cell rich large B-cell 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.
