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.

Spanish Surname or Origin Scenarios

Code the primary site C031 [Mandibular gingiva]. Code the histology 8033 [sarcomatoid carcinoma]. This tumor originated in the mandibular gingiva and invaded the bone (mandible) -- It did not originate in the bone. This type of tumor does not originate in bone.

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.

Record the radiation as first course of treatment even though it was delayed for several months.

Radiation is highly effective when there is a small or microscopic amount of tissue left at the margin following prostatectomy. In most regions, radiation therapy is the standard of care for positive margins at prostatectomy.

For a case diagnosed in 2003, code 8507/3 [Duct micropapillary carcinoma]. See Coding Complex Morphologic Diagnoses, revised August 2002, 3rd example on page 5 and page 3, #4.

For cases diagnosed 2007 or later, code 8507/3 [Duct micropapillary carcinoma]. Use rule H12.

For cases diagnosed 2007 or later:

There are two primaries. Primary 1: The two tumors described on the pathology report from the lumpectomy are a single primary using rule M13. Primary 2: Disregard the foci of residual DCIS. Paget disease of the nipple is a separate primary using rule M12.

Primary 1: invasive mucinous adenocarcinoma and extensive ductal carcinoma in situ: Code the histology as 8480/3 [mucinous adenocarcinoma] using rule H27.

Primary 2: Paget disease of nipple: Code the histology as 8540/3 [Paget disease] using rule H14.

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.

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 80 can be used for positive lymph nodes when you are unable to determine if they are regional or distant. CS Lymph Nodes code 80 is provided for this situation in accordance with the downstaging rule.

Code 80 should be used very infrequently and only when there is no indication whether the involved lymph nodes are regional or distant.

If the number of tumors is known, code the number in Multiplicity Counter. If foci are measured, include them in the multiplicity counter. If the only information available is "multiple foci" assign code 99.

For the case above, code 06 in the multiplicity counter (3 tumors on each side).
