Primary Site/EOD-Extension/EOD-Lymph Nodes--All Sites: What codes are used to represent these fields for an "extramedullary myeloid tumor (granulocytic sarcoma)" of the colon with positive or negative lymph nodes?
For cases diagnosed 1998-2003:
If only the extramedullary site is involved, such as colon, code the Primary Site field to the site of origin. Granulocytic or myeloid sarcoma is an exception to the rule that all leukemias should be coded to bone marrow as the primary site. Granulocytic sarcoma is a deposit of malignant myeloid cells in a site other than bone marrow (extramedullary). For EOD staging, granulocytic sarcoma [9930/3] is included in the Hematopoietic, Reticuloendothelial, Immunoproliferative and Myeloproliferative Neoplasms scheme and the Extension field is coded to 10 when the lymph nodes are negative, since it (like solitary plasmacytoma) is a localized deposit of tumor.
However, if the regional lymph nodes associated with the extramedullary primary site are involved, code the EOD-Extension field to 80 [Systemic disease] because the disease is no longer an isolated deposit of malignant granulocytes (in other words, it is not localized).
The EOD-Lymph Nodes field is coded to 9 regardless of whether or not the lymph nodes are involved because that is the only allowable code for that field.
Tumor Size/Neoadjuvant Treatment: If a patient discontinues neoadjuvant therapy and then has surgery, how is the pathologic tumor size coded with the pathologic tumor size greater than the clinical tumor size? Currently, we are instructed to code 999 for the pathologic tumor size when neoadjuvant therapy is given; what happens when neoadjuvant chemotherapy is discontinued after 3 cycles (plan for 4 cycles)?
Assign 999 for pathologic tumor size when patient has received neoadjuvant therapy, even when neo-adjuvant therapy is not completed. Describe the details in text fields.
Date of Diagnosis--Sarcoma: Should the date of diagnosis be coded to the date of biopsy or the date of birth for an infant biopsied at 3 days of age and stated to have a diagnosis of congenital alveolar rhabdomyosarcoma, widely metastatic?
Code the date of the biopsy as the date of diagnosis. This is the date the cancer was first identified by a medical practitioner.
Note: SEER collects the Month and Year of diagnosis. The "day" of diagnosis is not collected by SEER.
Reportability/MP/H Rules/Histology--Ovary: What is the histology code for an ovarian tumor described as a mucinous borderline tumor, intestinal type?
Mucinous borderline tumor, intestinal type, of the ovary is not reportable. The behavior is /1. There is no applicable histology code for this histology when it ocurs in the ovary.
Chemotherapy--Breast: Is chemotherapy administered for inflammatory breast cancer also coded as therapy for an in situ tumor in the contralateral breast?
Yes. Because chemotherapy would likely affect both primaries, code it as treatment for both the in situ and the inflammatory breast cancers.
First Course Treatment--Lymphoma: Should the use of proton pump inhibitors be coded as treatment for lymphoma primaries in patients with H Pylori?
No, do not code proton pump inhibitors as treatment. These are used for gastric acid suppression. Proton pump inhibitors are used to treat symptoms, not the lymphoma itself.
MP/H Rules/Histology--Breast: Patient has single invasive left breast tumor diagnosed in 2008. Final pathology diagnosis is "Invasive solid papillary carcinoma". No mention of ductal in report. What is histology?
For cases diagnosed 2007 or later:
As of July 2010:
Code the histology 8503 [Infiltrating papillary adenocarcinoma].
This is solid papillary, not solid AND papillary carcinoma. Solid is an adjective modifying papillary, in other words, a subtype of papillary. We do not have a code for solid papillary, so we code to the NOS, papillary using rule H14.
Immunotherapy: Is immunotherapy ever palliative treatment according to any oncologists or SEER?
Any treatment that destroys or modifies cancer tissue should be recorded as the appropriate type of treatment -- chemo, immuno, etc. Even if immunotherapy is given for symptoms/palliative treatment, it is likely to kill off tumor cells.
CS Site Specific Factor/CS Lymph Nodes--Breast: If the ITCs are greater than 0.2 mm, how are these fields coded?
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.
Lymph nodes with metastases greater than 0.2 mm are counted as positive. Code in CS Lymph Nodes and CS Regional LN Positive. Do not code ITC's greater than 0.2 mm in CS Site Specific Factor 4.
Reportability--Hematopoietic, NOS: The Abstracting and Coding Guide for the Hematopoietic Diseases, page 47, states to determine whether the physician is using the term myelodysplasia to describe bone marrow marrow malfunction or a neoplasic syndrome in order to determine reportability. What do we do when there is no information one way or the other?
For cases diagnosed prior to 1/1/2010:Without further information, the term "myelodysplasia" alone is not reportable. If a more definitive diagnosis is made later, the case may become reportable.
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.
