Extension/CS Extension--Prostate: Do the prostate guidelines used for EOD still apply to cases diagnosed 2004 forward?
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 cases diagnosed 2004 and forward, refer to the Collaborative Staging manual.
The 2004 CS guidelines have been agreed upon by all standard setters and have been reviewed by the COC/AJCC urologists.
Note: Do not use the SEER EOD guidelines with Collaborative Staging.
Reportability: Is a tubular adenoma reportable if the final diagnosis is "high grade atypia" and the diagnosis comment is "atypia limited to muscularis mucosa areas of pseudostratification [formerly qualifying for carcinoma in situ]"?
This case is not reportable.
The pathologist would need to include "carcinoma in situ" as part of the final diagnosis in order for this case to be reportable.
MP/H Rules/Behavior--Melanoma of Skin: How are histology and behavior coded for a "malignant melanoma in situ with regression"? See Discussion.
Per the microscopic portion of the path report, there is a zone of regression within the confines of the lesion, such that the possibility of antecedent invasive disease at the site cannot be ruled out with certainty.
For cases diagnosed 2007 or later:
Code malignant melanoma in situ with regression to 8720/2 [Melanoma in situ].
Code the histology according to the histologic type specified in the pathology report final diagnosis. Code the behavior as specified in the pathology report. Regression does not affect the coding of histology or behavior. See Melanoma Histology Coding rule H5. See 2007 SEER manual instructions for coding behavior, page 84.
Primary Site/CS Extension--Lymphoma: How are these fields coded for an epidural lymphoma that extends into the bone marrow of the adjacent vertebral body?
For cases diagnosed prior to 1/1/2010:After verifying that the lymphoma originated in the epidural space, code to C729 [nervous system, NOS (epidural)]. This is a rare type of extranodal lymphoma.
Assign CS extension code 80 for lymphoma with bone marrow involvement.
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.
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.
Reportability/Histology--Head and Neck: Is a right cerebellopontine (CP) angle endolymphatic sac papillary tumor (ELST) reportable? If so, what is the histology code?
Revised December 2015
ELST is reportable. Code histology to adenocarcinoma (8140/3). Code primary site to inner ear (C301).
Endolymphatic sac tumors are rare non-metastasizing adenocarcinomas that originate in the endolymphatic sac of the inner ear (C301). They are slow growing and widely invade, and in later stages often destroy, the petrous bone. The WHO Classification assigns ICD-O-3 code 8140/3.
Race, ethnicity/Spanish surname or origin: SEER Program Manual instructions state, "Portugese, Brazilians and Filipinos are not Spanish; Code non-Spanish (code 0)." How is that determined? Is that based SOLELY on birthplace? See Discussion.
The following are scenarios for which we would like clarification on how to code Spanish Ethnicity.
Birthplace Portugal; text states Spanish, south American or European Spanish
Birthplace Brazil, last name is on Spanish surname list; pt is married female. Text states "Hispanic female, NOS"
Birthplace Brazil or Portugal, text states patient is "Mexican", last name is on Spanish surname list
Information about Spanish origin is available for both of these cases; code the race as Hispanic. Use the SEER manual instruction when the only information available is that the patient was born in Portugal, Brazil or the Philippines. In the absence of additional information, do not assume Hispanic. However, if additional information is available stating that the patient is Hispanic, code as Hispanic.
#2: Invasive ductal carcinoma, well-differentiated, 1.0cm (12:30 o'clock). -Minor component of DCIS, low-grade? See Discussion.
In the MP/H Rules, Table 1 lists apocrine as a type of intraductal carcinoma. Apocrine does not appear in Table 2, the list of specific duct carcinomas. If Apocrine is a type of ductal carcinoma, then Rule M11 would make this a single primary. If it is a single primary, what is the histology?
For cases diagnosed 2007 or later:
Using rule M11, there is one primary in the left breast. Apocrine is a specific duct carcinoma. To make this more clear, apocrine will be added to Table 2 in a future revision.
To code the histology, go to the multiple tumors module and start with rule H20. Stop at rule H29 and code the histology with the numerically higher ICD-O-3 code, 8500/3.
