Ambiguous Terminology: Why do the instructions for this field use the term "accession" rather than "abstract"?
The purpose of the new data item "Ambiguous Terminology" is to identify cases that were put into the cancer registry database without a conclusive diagnosis. The decision to accession the case was influenced by ambigous terminology. The emphasis is on accessioning the case rather than abstracting it.
Type of Multiple Tumors--Lung: Is this field coded to 40 [Multiple invasive] or 80 [Unk in situ or invasive] when only one nodule is biopsied of multiple existing nodules for a reported single lung primary? See Discussion.
The right lung has 4 tumor nodules in the upper lobe. Biopsy of one tumor is positive for moderately differentiated adenocarcinoma. No other work up performed.
Should code 40 be used because we dont know the behavior of the other nodules?
The best code to use in this case is 40 [multiple invasive]. For lung only, it is assumed that all of the tumors are the same histology and that all are invasive.
First Course Treatment--Melanoma: How and where is the excision for an in-transit metastasis coded if the in-transit metastasis is coded in CS Lymph Nodes? See Discussion.
Excision of skin of scalp nodule reveals in transit metastasis of melanoma. Patient also has lung metastasis and begins systemic treatment. No primary tumor identified.
Code the excision in Surgical Procedure of Other Site because no primary tumor was identified.
Histology--CLL/SLL: What is the correct histology code for a lymph node described in the pathology report comment section as "phenotypically consistent with chronic lymphocytic leukemia"? See Discussion.
Current rules instruct us to select the lymphoma code for lymph node and/or tissue with the dual diagnosis of chronic lymphocytic leukemia/small lymphocytic lymphoma. We have a cervical lymph node biopsy with that dual diagnosis, however, the pathology comment states that after immunohistochemistry testing, the lymph node is "phenotypically consistent with chronic lymphocytic leukemia." No bone marrow or blood work-up is performed.
For cases diagnosed prior to 1/1/2010:Code Small Lymphocytic Lymphoma. The current rules have not changed. Code to lymphoma because the diagnosis was made on a lymph node.
"Phenotypically consistent" means the lymph node contains CLL/SLL, not some other hematopoietic or metastatic disease.
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.
Date of Conclusive Terminology: Is there an applicable timeframe when coding this field?
There is no strict timeframe for Date of Conclusive Terminology. The diagnosis using conclusive terminology could be made any time following the diagnostic work-up.
The date of conclusive terminology is related to code 2 [ambiguous term followed by conclusive term] in the data item "Ambiguous terminology." Assign code 2 when a conclusive diagnosis is made 60 days or more after a diagnosis using ambiguous terminology. Record the date of the conclusive diagnosis in "Date of Conclusive Terminology."
Reportability/Diagnostic Confirmation: If a diagnosis based solely on positive flow cytometry is reportable even if a bone marrow biopsy is negative, how is diagnostic confirmation coded?
For cases diagnosed prior to 2010
The case is reportable if a recognized medical practitioner says the patient has cancer.
A flow cytometry alone is not diagnostic but it may be supported by either a positive bone marrow or a clinician's statement. If the clinicians statement is based only on flow cytometry, code diagnostic confirmation to 8 [Clinical diagnosis only].
EOD-Pathologic Extension--Prostate: When coding a prostate case with a date of diagnosis prior to 1995, is the EOD-Pathologic Extension-Prostate field left blank?
For tumors diagnosed prior to 1995, leave EOD-Pathologic Extension--Prostate field blank.
Code all EOD fields according to the EOD coding scheme in effect for that year of diagnosis.
Multiplicity Counter-Breast: The general instructions say to ignore separate microscopic foci when determining when to use the single tumor or multiple tumor modules. Do these instructions apply if sizes are given for the foci? See Discussion.
For instance, would a 1.2 cm breast tumor with 3 scattered microscopic foci ranging from 2-4 mm be treated as multiple tumors (4), or as a single tumor?
If the microscopic foci are measured and listed as part of the diagnosis, they should be counted as multiple tumors.
MP/H Rules/Multiple Primaries/Histology--Prostate: How many primaries should be abstracted and how should the histology field(s) be coded for a case in which the pathology specimen showed adenocarcinoma in 20% of the tissue and sarcoma in 50% of the tissue? See Discussion.
Patient has TURP. The final path diagnosis is adenocarcinoma in 20% of tissue and sarcoma in 50% of tissue.
Because it is unknown whether there is a single or multiple tumors, rule M1 (Other Sites) is used which states the case is to be abstracted as a single primary.
Single invasive histology rules are followed to rule H16, but table 2 does not contain a mixed code for this situation, even though ICD-O-3 has a code 8933/3 for "adenosarcoma". Therefore, rule H17 is applied that states to use the highest code, which in this case would be 8800/3 [Sarcoma, NOS]. Is this correct?
For cases diagnosed 2007-2014, code as two primaries, one adenocarcinoma and the other sarcoma.
This is two tumors (adenocarcinoma and separate sarcoma) until proven otherwise. Do not code as adenosarcoma, as this is a gyn-specific diagnosis. Adenosarcoma of the prostate is not a recognized entity in the WHO classification of prostate tumors.
MP/H Rules/Histology--Colon: How is histology coded when the final pathology diagnosis is "adenocarcinoma with extensive mucinous features" and the percent of mucinous features is not stated?
Code 8140 using rule H6. Rule H6 applies because the percent of mucinous is not specified.
