Report Question ID Question Discussion Answer Year
20021144 EOD-Extension--Colon: What code is used to represent this field for a mid-ascending colon primary that invades through muscularis propria and into subserosal fibroadipose tissue that also presents with a "separate serosal nodule" of carcinoma within cecum that is consistent with a tumor implant (cT3, N0, M1)?

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 85 [Metastasis], because the nodule of carcinoma in the cecum is not contiguous with the mid-ascending primary colon tumor.

First Course Treatment: 1) When is Decadron (Dexamethasone) coded as cancer treatment? 2) When Decadron is given to a patient with multiple myeloma, is it coded as treatment only if given in combination with chemotherapy? See discussion.

SEER Book 8 states that Decadron is an important therapeutic agent for treatment of multiple myeloma. In the Abstracting and Coding Guide for the Hematopoietic Diseases, Decadron is a hormonal treatment for multiple myeloma "when given as part of a chemotherapy regimen".

For cases diagnosed 1/1/2003 and after:

1. Code hormone therapy to 01. Code any therapy administered to treat cancer tissue that achieves its effect on cancer tissue through a change in the hormone balance in the hormone therapy field. Decadron is coded for leukemias, lymphomas and multiple myelomas primaries. It is coded for other sites only when stated to be cancer-directed treatment.

2. Code hormone therapy to 01. Decadron should be coded as hormone therapy for multiple myeloma when given alone or as part of a first course of treatment chemotherapy regimen.

20021210 Date of Diagnosis/Histology (Pre-2007)--Breast: When there is a delay between the clinical diagnosis of a malignancy and the surgical resection of the primary site, can the resection be used to code the date of diagnosis, extension, size of the primary tumor, and histology? See discussion.

For example, mammogram March 28th states "certainly represents malignancy." Nothing else done until November 1st when pt presents w/skin retraction on PE and bone mets. A mastectomy November 6th shows "ductal ca w/dermal lymphatic invasion and tumor measuring 3.5 cm."

How is the date of diagnosis, extension, tumor size & histology coded for this case?

For tumors diagnosed prior to 2007:

Code the Date of Diagnosis to March. Code the Histology field to 8500/3 [Infiltrating duct carcinoma]. Histology can be upgraded from a clinical histology to a pathological histology anytime.

For cases diagnosed 1998-2003, in coding extension, you need to assess whether there has been progression of disease or not. If progression of disease is verified, do not code extension using the surgical information from November. Code the extension and tumor size based on the mammogram and physical examination at the time of the mammogram, if available.

If no progression of disease is verified, use surgical information to code extension and tumor size.

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.

20021188 Multiple Primaries (Pre-2007)--Testis: How many primaries should be reported when seminoma is diagnosed simultaneously in both testicles and both tumors are encapsulated?

For tumors diagnosed prior to 2007:

Report this cases as two primaries, unless there is information in the record confirming one primary.

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.

20021190 Histology (Pre-2007)--Bladder: What code is used to represent the histology "transitional cell and small cell carcinoma" of the bladder? See discussion. Code 8045/3 is used for combination codes that represent a mixture of small cell carcinoma and any other carcinoma. When we use this histology code for bladder primaries with mixed transitional cell and small cell carcinoma, we encounter a problem with the SEER edits (site and morphology conflict).

For tumors diagnosed prior to 2007:

Please see SEER Inquiry question ID number 20041104.

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.

20021053 EOD-Extension--Pancreas: How would you code extension for the following non-surgically treated pancreas primaries? None of these cases has TNM staging to assist with classifying the extent of disease. See discussion.

1) CT scan: Cystic lesion in body of pancreas. Discharge dx: pancreas ca.

2) Discharge dx: CBD obstruction due to probable early ca in head of pancreas.

3) CT scan: mass involves the head and body of the pancreas. No evidence of abdominal mets. Discharge dx: Locally advanced pancreatic ca.

4) H&P: Pt with splenomegaly probably secondary to splenic vein thrombosis and a large ca of the tail of pancreas. Imp: Advanced pancreatic ca of the tail of pancreas. Would you code extension to splenic vein [56]?

5) H&P: Pancreatic ca with extension or mets into porta hepatis. (Would you assume direct extension or mets?)

6) CT scan: Pancreas ca. Significant peritoneal implants. (Would you assume the implants to be related to the pancreas primary and code as involvement?)

For cases diagnosed 1998-2003:

The information provided for these pancreatic primary examples is very limited. Additional information should be sought. If not available, code the EOD-Extension field to:

1) 10

2) 10

3) 10

4) 99

5) Assuming primary in head, body or tail of pancreas, 76

6) 85

Multiple Primaries (Pre-2007)--Breast: When two breast tumors with two different histologies, such as duct and mucinous are diagnosed in the same breast at the same time, are they reportable as two primaries? See discussion.

Our rule is that multiple lesions of different histologic types are separate primaries. However, for separate tumors of duct and lobular, we report as a single primary. Since we now have a combination code for duct and other types of ca, do we report as a single primary or continue to report as separate primaries?

For tumors diagnosed prior to 2007:

When there are two breast tumors, one mucinous, the other duct carcinoma, report as two primaries when the pathologist's opinion clearly states that there are separate primaries.

If there is no such information from the pathologist, the two tumors must be separate with clear (negative) margins to be reported as two primaries. Otherwise, report as one primary.

The ICD-O-3 combination codes are not intended to combine tumors of different histologic types.

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.

20021036 EOD-Extension--Urinary Tract: Can the rules used to code bladder extension involving the term "no involvement of muscularis/and no mention of subepithelium/submuscosa" be used to code extension for other urinary tract primaries, such as ureter?

For cases diagnosed 1998-2003:

No. The inferred descriptions of noninvasion apply to bladder cases only.

 2002
20021159 Histology (Pre-2007)--Breast: What code is used to represent the histology "mucinous carcinoma with Paget disease"?

For tumors diagnosed prior to 2007:

Code the Histology field to 8480/3 [mucinous carcinoma]. This answer assumes the patient presented with a single tumor. There is no combination code that includes these two entities. According to the rules for Coding Complex Morphologic Diagnoses, it would appear that the case should be coded to 8540 [Paget disease] because it is the higher code. However, this combination of histologies represents an exception to that rule. The prognosis for mucinous carcinoma is worse than the prognosis for Paget disease. As a result, it would be more appropriate to the histology to mucinous carcinoma.

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.

20020066 Chemotherapy: How is treatment with Iressa (Gefitinib) coded?

Code treatment with Iressa as chemotherapy.

Iressa is an epidermal growth factor inhibitor. While it doesn't kill cells directly, it damages the cell reproduction process. We classify it as a chemotherapy agent.
