CS Lymph Nodes/CS Mets at Dx--Ovary: How are renal lymph nodes coded for ovary primaries?
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.Code involvement of renal lymph nodes under CS Mets at Dx. Renal lymph nodes are not listed as regional lymph nodes for ovary; therefore, code involvement of renal lymph nodes under CS Mets at Dx.
MP/H Rules--Sarcoma: How many primaries should be abstracted for chondrosarcoma of right toe in 2002, of right lower leg in 2006 and right tibia in 2007? See Discussion.
A patient had a myxoid chondrosarcoma of the right toe in 2002. This was amputated and staged as T2 - high grade. Patient had a recurrence in the lower right leg in 2006. At this time he had a below knee amputation. The tumor in 2006 was stated to be similar histologically to the 2002 tumor with pathologic comparison done. Then in 2007 the patient presents with pain in right knee and stump. CT says compatible with recurrent disease, but no copies of path sent. Patient then had an above knee amputation, with diagnosis of clinically recurrent chondrosarcoma of tibia. How many primaries should be abstracted? Is 2007 diagnosis a new primary?
For cases diagnosed 2007 or later:
Abstract two primaries in this case, 2002 and 2007.
The first primary was diagnosed in 2002. The 2006 diagnosis would not be a new primary according to the rules in effect at that time (2004 SEER manual, page 11, rule 5, exception 1).
Use the current MP/H rules to compare the 2007 diagnosis to the 2002 diagnosis. Start with rule M3 and stop at rule M10. The 2007 diagnosis is a separate primary.
CS Extension--Brain and CNS: How is CS Extension coded for a malignant meningioma that demonstrates extension into adjacent brain tissue?
For malignant brain tumors, code 60 represents extension into the meninges. Would code 60 be the correct code for extension from a malignant meningioma into brain tissue?
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.Assign CS extension code 60 for malignant meningioma with extension to adjacent brain tissue.
According to the I&R, this section of CS was taken directly from SEER Summary Staging, since AJCC does not have a staging system for these tumors.
Multiplicity Counter--Ill-defined sites: How is this field coded for Ill-Defined sites (C760-C768)?
Code the number of tumors present if known. If the number of tumors present is not known, code 99 [unknown number of tumors, unknown if multiple tumors].
Ambiguous terminology: Is the phrase "malignancy is highly considered" reportable given that the phrase "considered to be malignant" is reportable per SINQ 20061094?
"Malignancy is highly considered" is not a reportable ambiguous term.
Diagnoses qualified by the phrase "considered to be malignant" are reportable because this phrase is interpreted as "This diagnosis is malignant."
CS Extension--Brain and CNS: How is this field coded for a malignant brain tumor that presents as a lesion with significant pressure on the left frontal ventricle and dilation of the right ventricles? See Discussion.
CS Extension code 30 includes tumor that invades or encroaches upon the ventricular system. Does significant pressure mean the same thing as encroach?
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.Do not assign extension code 30 in this case unless there is evidence elsewhere of ventricular system involvement.
"Significant pressure" is not synonymous with encroachment or involvement. See the list of ambiguous terms for CS staging on page 121 of the 2007 SEER manual.
Ambiguous terminology/Reportability--Kidney: Is a case reportable if a biopsy diagnosis of "suggestive of oncocytoma, malignant neoplasm cannot be excluded" follows a CT scan that was read as "suspicious for carcinoma"? See Discussion.
Pt is nursing home resident. CT abdomen/pelvis shows a "mass in the right kidney, highly suspicious for renal cell carcinoma". CT-guided needle biopsy performed with final diagnosis: "Neoplasm suggestive of oncocytoma. A malignant neoplasm cannot be excluded." No other information is available.
This case is not reportable based on the information provided. The suspicious CT finding was biopsied and not proven to be malignant. "Suggestive of" is not a reportable ambiguous term.
