Ambiguous Terminology: Why was 60 days chosen for ambiguous terminology?
The Histology Task Force approved a 60 day time frame for ambiguous terminology.
The majority of cases are first identified by ambiguous terminology; for example, a patient has a mammogram that shows a lesion suspicious for cancer. That first indication of cancer prompts a work-up to either confirm or rule-out the cancer diagnosis.
The data item "Ambiguous terminology" is not intended to capture information on this routine method of detecting and diagnosing cancer. The 60 day time frame should keep these cases out of the ambiguous terminology data item.
The data item is intended to identify those cases where the cancer diagnosis is NOT confirmed during the work-up, but the case is still entered into the database. For example a patient who has a TRUS because of elevated PSA. The pathology from the TRUS says "Suspicious for adenocarcinoma of the prostate." The physician only documents that the patient is to return in 6 months for another PSA and TRUS. The registrar would enter this case into the data base because the word "suspicious" is on the ambiguous terminology list.
CS Tumor Size: Is a measured "area" equivalent to a tumor, mass or lesion size? See Discussion.
Collaborative Stage manual, page 26
Rule 4a: "always code size of the primary tumor, not size of the polyp, ulcer, cyst or distant metastasis."
Rule 4e: Additional rule for breast primaries: Example: Duct carcinoma in situ covering a 1.9 cm area with focal areas of invasive ductal carcinoma. Record the tumor size as 1.9 cm.
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.In general, a measured area is not equivalent to a tumor size.
Do not apply the rule related to the breast example to other primary sites. This example in the CS manual pertains to coding tumor size for breast primaries when the size of the invasive component is not stated. In the example, the area involved with duct carcinoma in situ is the only measurement available. The size of the invasive component was not given.
CS Extension--Prostate: Should CS Clinical Extension always be coded to 99 [Extension unknown] for prostatic adenocarcinoma found incidentally during surgery for another primary or at autopsy? See Discussion.
Patient had a cystoprostatectomy for bladder cancer. Pathology report states only 2 microscopic foci of prostate adenocarcinoma found on LEFT side of gland. Physician notes state patient has been followed for 4 years with a nodule in the RIGHT prostate and has refused biopsy despite rising PSA. There was no definite statement of suspected cancer.
Should CS Clinical Extension be coded 99 because prostate cancer wasn't clearly stated to have been suspected until cystoprostatectomy? Or could we code the right-sided "nodule" as clinically apparent (CS Extension 20), even though path found tumor only on the left (which is how we would code a standard prostate case)?
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 CS extension 99 [Extension unknown]. This prostate cancer was not clinically evident; it cannot be clinically assessed based on the information provided.
Note: This is an unusual case. A DRE was performed and a nodule was palpated on the right that was not cancer. The other lobe is presumed to have been negative because it was not mentioned.
MP/H Rules/Multiple Primaries: When the pathology report from a FNA or other biopsy states an "in situ" carcinoma and the patient waits more than 60 days for a more definitive procedure which documents an "invasive" carcinoma, is this reported as two primaries?
For cases diagnosed 2007 or later:
No. When the invasive component is discovered as part of the work-up phase leading to treatment decisions, the case should not be abstracted as a multiple primary. In the rare instance when a patient has not been treated and is still having diagnostic work-up greater than 60 days after the malignancy is diagnosed, do not count the invasive diagnosis as a new primary.
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.
CS Extension/CS Lymph Nodes--Lung: How are these fields coded if a lobectomy path specimen indicates that two intrapulmonary lymph nodes are involved by direct extension from the primary tumor?
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 regional lymph node involvement in CS lymph nodes even when the lymph nodes are involved by direct extension. Do not code direct extension to lymph nodes in CS extension.
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/Terminology--Prostate: Is the diagnosis of "atypical glands suspicious for adenocarcinoma" sufficient to report a prostate cancer if a note states that there is "insufficient atypia to establish a definitive diagnosis of malignancy"? See Discussion.
Date of report is July 2005. One positive specimen of 12.
Specimen 6: Diagnosis = Prostate tissue with a small focus of atypical glands suspicious for adenocarcinoma. Note. There is insufficient cytologic and/or architectural atypia to establish a definitive diagnosis of malignancy. Negative basal cell staining with cytokeratin... in atypical glands is consistent with the diagnosis of suspicious for adenocarcinoma. In addition, the diagnosis is suppported by a positive staining for alpha-methyl COA racemase (P504S), a recently discovered marker that is preferentially expressed in prostate cancer...
This case is reportable. The diagnosis states "suspicious for adenocarcinoma." "Suspicious for" is a reportable ambiguous term.
The additional stains supported this "suspicious" diagnosis. A more definitive diagnosis could not be made based on this specimen.
MP/H Rules/Recurrence--Breast: Do we use a pathologists comment of "recurrent ductal carcinoma" found in the pathology report for a new specimen to determine whether the new specimen actually represents a new primary or recurrent disease? See Discussion.
The patient had a left breast cancer LIQ, ductal with DCIS. Nodes (-) diagnosed in 1998
Treatment: Lumpectomy-clear margins
Refused radiation
Hormone therapy: Tamoxifen
Present: June 2007
Left breast-invasive ductal ca, UOQ
Pathology report comments: Recurrent ductal ca.
Left axillary nodes (+)
For cases diagnosed 2007 or later, apply the 2007 MP/H breast rules. Go to the multiple tumors module and begin with rule M4. Stop at rule M5: tumors diagnosed more than 5 years apart are multiple primaries.
The only time you can accept a pathologist's statement of recurrence is when the statement is made based on a review of the slides from the previous diagnosis compared to the slides from the current 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.
