Primary Site/Summary Stage 2000/EOD-Extension--Lymphoma: How are these fields coded when a CT Impression states: Large retroperitoneal/abdominal mass resulting in extra-hepatic biliary obstruction & bilateral urinary tract obstruction & encasement of major vessels most c/w lymphoma? See Discussion.
CT findings state: Very lg sft tiss mass encasing pancreatic head & portion of body, splenic & portal veins, celiac axis, sup mesenteric artery & bilateral renal veins. Two components to this mass: 1) retroperitoneal mass encasing great vessels and 2) peritoneal component 10.8cm size, displaces bowel & other structures & encases vessels.
If the physician stated "this is bulky disease" would that change the EOD?
For tumors diagnosed 1998-2003:
Based on the information provided:
The topography code for this lymphoma is C772 [Intra-abdominal lymph nodes].
Code SEER Summary Stage 2000 to 5 [Regional NOS].
Code EOD Extension to 20. More than one lymph node region below the diaphragm is involved (retroperitoneal and peritoneal). The organs mentioned are not involved by the lymphoma. The bulk of the masses is causing obstruction by displacing and/or encasing organs.
A physician description of "bulky disease" would not change the EOD for this case.
Behavior Code--Breast: How is this field coded for a "non-invasive Paget disease of the breast?" See Discussion.
Historically, SEER collected Paget Disease of the breast with a behavior code of 3 [invasive]. There is no documentation to support this. The SEER EOD Manual only states that if the code is "05" [Pagets disease (without underlying tumor)], the behavior must be a 2 [in situ] or a 3 [invasive].
Code the behavior as /2 [in situ] for noninvasive Paget disease of breast. Noninvasive is a synonym of in situ.
If the pathology report documents that the Paget disease is in situ, the matrix principle in ICD-O allows you to change the behavior code to match the pathologist's statement.
CS Extension/Histology (Pre-2007)--Breast: Paget disease with underlying DCIS. How should CS Extension, SEER Summary Stage 2000, histology, and behavior be 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.
For tumors diagnosed prior to 2007:
Based only on the information provided above,
1. The CS extension code is 07 [Paget disease of nipple (without underlying invasive carcinoma pathologically)].
2. The SS 2000 stage is 1 [Localized].
3. The histology code is 8543 [Paget disease and intraductal carcinoma of breast]. The behavior code is 3 [Malignant].
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.
EOD-Extension--Breast: If the pathology report states "infiltrating duct carcinoma...measuring 7mm in diameter...focal areas of intraductal carcinoma," do we code this field to 14 [Invasive and in situ components present, size of entire tumor coded in Tumor Size and in situ described as minimal] or to 16 [Invasive and in situ components present, size of entire tumor coded in Tumor Size and proportions of in situ and invasive not known]?
For cases diagnosed 1998-2003: If 7mm is the measurement of the infiltrating duct portion of this cancer, assign extension code 13 [Invasive and in situ components present, size of invasive component stated and coded in Tumor Size].
If 7mm is the size of the whole malignancy and the size of the invasive portion cannot be determined, assign extension code 14 [Invasive and in situ components present, size of entire tumor coded in Tumor Size (size of invasive component not stated) and in situ described as minimal (less than 25%)]. "Focal areas of in situ carcinoma" qualifies as minimal.
Multiple Primaries (Pre-2007)--Colon: What is the number of primaries for a case of familial polyposis with at least three separate tumors having invasive adenocarcinoma, one in the rectum? See Discussion.
A patient had a total proctocolectomy and was found to have familial polyposis. At least 3 separate tumors were identified with invasive adenocarcinoma, one of which was in the rectum. Is this 2 primaries: C18.9 with 8220/3 and C20.9 with 8140/3 or is this all one primary cancer?
For tumors diagnosed prior to 2007:
Familial polyposis is always a single primary. Code the primary site for the case example above to C199 [colon and rectum].
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.
First Course Treatment: If a patient makes a blanket refusal of all recommended therapy or refuses all treatment before any therapy was recommended, are only immunotherapy and hematologic/endocrine therapies to be coded as refused (code 87)? Or should all treatment modalities be coded as refused if a patient makes a blanket refusal? Or should none of the treatment modalities be coded as refused because we do not know what would have been recommended? See Discussion.
Coding instructions for immunotherapy and for hematologic/endocrine procedures state that Code 87 is to be assigned if either of the following circumstances apply: 1) If the patient made a blanket refusal of all recommended treatment. 2) If the patient refused all treatment before any was recommended. These instructions are not included for other treatment modalities.
When the patient refuses treatment, the first course of therapy is no treatment. Code all treatments as refused.
CS Site Specific Factor 1--Colon: If the registrar did not support the CEA code recorded with the appropriate text documentation, should the central registry accept the registrars coding or change the value to 999?
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.Accept your registrars' codes at your discretion. It is encouraged, but not required, to enter text for CS data elements. These cases do not automatically default to code 999.
Histology (Pre-2007): Can we ever code this field using a more specific cell type from a metastatic site specimen rather than to a less specific cell type from the primary site specimen? See Discussion.
The histology for a metastatic deposit biopsy is mucin-producing adenocarcinoma. This report states that the primary site is the stomach. It is more specific than the histology from the stomach biopsy described as adenocarcinoma, NOS.
For tumors diagnosed prior to 2007:
Code the histology for the case example to 8481/3 [mucin-producing adenocarcinoma], the more specific histology.
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.
CS Tumor Size--Ovary: The size of a cyst is not coded in this field. However, can the size of a "cystic mass" be coded in this field? See Discussion.
The specimen consists of a cystic mass which weighs 1520 grams and measures 23 x 17 x 10 cm.
If the tumor is described as a "cystic mass" and only the size of the entire mass is given, code the size of the entire mass, because the cysts are part of the tumor itself.
Please note: Ovarian cancer stage is not based on tumor size.
Ambiguous Terminology/Reportability: Are the terms "bordering on" and "may represent" diagnostic of cancer? See Discussion.
Pathology report states "...florid micropapillary hyperplasia, focally atypical with features bordering on low grade micropapillary ductal carcinoma in situ."
The terms "bordering on" and "may represent" are not diagnostic of cancer. These terms are not on the list of ambiguous terms that constitute a diagnosis of cancer. The diagnosis in the example above is not reportable to SEER.
