Accept the reportable ambiguous terminology from the body of the mammogram. Record the date of the mammogram as the date of diagnosis.

The guidelines on page 4 of the 2007 SEER manual addressing discrepancies within the medical record can be applied to discrepancies within one report.

The instructions are:

If one section of the medical record(s) uses a reportable term such as

apparently and another section of the medical record(s) uses a term that is not on the reportable list, accept the reportable term and accession the case.

For cases diagnosed 2007 and later, the correct histology code is 8000/3 [cancer]. The steps used to arrive at this decision are:

Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Other Sites Histology rules because no specific rules have been developed for prostate primaries.

To determine the histology, start at the SINGLE TUMOR: INVASIVE ONLY module, rule H8. The rules are intended to be reviewed in consecutive order within a module. Code the histology documented by the physician when there is no pathology/cytology specimen or the pathology/cytology report is not available. Code the histology as 8000/3 [cancer] because that is the only available information. In the absence of a pathology report or any other histologic confirmation, code the histology based on the information available.

The case is not reportable.

The biopsy with a suspicious result (suspicious for adenocarcinoma) was disproven by the esophagectomy.

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.

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."

For cases diagnosed 2007 or later:

Yes. This is an example of a site-specific exception to the general rule to code only from the final diagnosis. The Colon Histology Rules specifically state that "other parts of the pathology report" may be used to identify a tumor arising from a polyp, adenomatous polyp, villous adenoma, or tubulovillous adenoma.

For cases diagnosed 2007 or later:

This is a single primary with renal pelvis as primary site.

Use the 2007 MP/H rules to determine if the 2007 diagnosis is a new primary. Use the Urinary rules, multiple tumors module. Start with rule M3. Follow the rules down to Rule M8 and stop. This is an example of implantation effect.

For cases diagnosed 2007 or later, this is a single primary. A single tumor is always a single primary.

Assign histology code 9400/3 [Astrocytoma, low grade]. This diagnosis was not revised or amended based on the later surgery. It is possible that the malignant component was entirely removed during the first surgery.
