Reportability--Head & Neck: What are the correct site and histology codes if a glomus tympanicum tumor of the middle ear is reportable?

Glomus tympanicum tumors of the middle ear are not reportable. The 2005 WHO Classification of Head and Neck Tumors classified these tumors as a borderline [/1] behavior and recorded them in the ICD-O-3 with histology code 8690 [glomus jugulare tumor, NOS].

According to WHO, "the distinction between jugular and tympanic paragangliomas can easily be made in the patient by modern imaging methods ... the jugular neoplasm is identified as arising from the jugular bulb region ... while the tympanic neoplasm is confined to the middle ear." Benign and borderline neoplasms of the middle ear [C301] are not reportable. The middle ear is not a reportable CNS site for benign and borderline tumors.

First course of treatment/Radiation therapy--Kidney: Patient has a CT-guided biopsy of a right renal mass with procedure details under the Interventional Radiology Procedure Note stating "Gelfoam tract embolization." Is this particular embolization treatment?

Gelfoam tract embolization for a CT-guided renal biopsy is not treatment. It is a method to plug the biopsy track to reduce the risk of hemorrhage.

Sequence Number Central--Brain and CNS: How is Sequence Number--Central coded for current/recent benign brain/CNS tumors when the patient has a history of an additional non-malignant CNS tumor diagnosed prior to 2004 (when these tumors became reportable to SEER)? See Discussion.

We are confused by the SEER Program Coding and Staging Manual 2018 instruction that states: This sequence number counts all tumors that were reportable in the year they were diagnosed even if the tumors occurred before the registry existed or before the registry participated in the SEER Program. Does this rule apply to benign and borderline CNS tumors?

Does this mean that any non-malignant CNS tumor diagnosed prior to 2004 should NOT be included in the sequencing (in the 60s range) if we were collecting non-malignant CNS per our State Registry reporting requirements prior to 2004?

Example: Patient has a March 2017 diagnosis of right sided vestibular schwannoma (C724-1, 9560/0) and a prior history of left sided acoustic neuroma (c724-2, 9560/0) diagnosed in 1991. How should sequence be coded for each primary in our file?

For your example, code the Sequence Number--Central as 61 for the 1991 diagnosis if this was a state registry requirement in 1991 and code 62 for the 2017 diagnosis.

20021004 Histology: What code is used to represent the histology for the abbreviation "ca"? See discussion.

The abbreviation "ca" results in inconsistency when coding histology by a group of coders. Many abbreviation guides list both cancer (8000/3) and carcinoma (8010/3) as definitions for "ca." Page 261 of the SEER Self Instructional Manual, Book 5 lists carcinoma as the definition for "ca."

Example: What histology is used for a case with a clinical diagnosis of "recently diagnosed uterine ca" with metastasis to the pelvic lymph nodes?

For uterine primaries, code the abbreviation "ca" to 8010/3 [carcinoma, NOS].

When coding death certificate only (DCO) cases, if the site is coded to an unknown primary and no specific histology information is available other than the abbreviation "ca," interpret ca as cancer (8000/3) per NAACCR Procedure Guidelines for Registries, Series V; Resolving Death Clearance Issues, page V-15.

20010118 All Surgical Fields/Radiation Sequence with Surgery--Unknown Primaries: What codes are used to represent these fields for an unknown primary treated with a radical neck dissection followed by radiation therapy?

For unknown primaries treated with a lymph node dissection and diagnosed 1/1/2003 and after, code:

1) Surgery to Primary Site: 98 [All unknown and ill-defined disease sites, WITH or WITHOUT surgical treatment].

2) Scope of Regional Lymph Node Surgery: 9 [Unknown or not applicable].

3) Surgical Procedure of Other Site: 1 [Surgery to other site(s) or node(s), NOS; unknown if regional or distant].

4) Radiation Sequence with Surgery: 3 [Radiation after surgery]. Any planned surgical treatment is used to code radiation/surgery sequence (per CoC I&R).

20031066 Histology (Pre-2007): Is 8524 [lobular mixed with other carcinoma] or 8490 [signet ring cell carcinoma] used to represent a diagnosis of "infiltrating lobular with signet ring features?"

For tumors diagnosed prior to January 1, 2004:

According to our pathologist consultant, for this specific case, code to 8490 [Signet ring cell carcinoma].

Our pathologist states: "Signet ring cell carcinoma is most often a variant of lobular carcinoma (as it appears to be in this case - it is less frequently a variant of ductal), and I think it's appropriate to code it as such. Coding to lobular would also be ok, though that would lose the special feature of the signet ring cells. I would rather not code to 8524, since it is not really a mix of lobular and something else."

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.

Multiple Primaries (Pre-2007)--Bladder: Should an invasive malignancy following an in situ malignancy by more than two months be a new primary? Why? See discussion.

Example: An in situ bladder case was diagnosed and treated. Three months later another TURB diagnosed an invasive bladder carcinoma. Is the invasive case reportable to SEER as a new primary?

For tumors diagnosed prior to 2007:

Yes. These are two primaries.

In situ cancers are not included in SEER incidence rates. Incidence rates must correlate with mortality rates.

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.

Multiple Primaries (Pre-2007)--Breast: When two breast tumors with two different histologies, such as duct and mucinous are diagnosed in the same breast at the same time, are they reportable as two primaries? See discussion.

Our rule is that multiple lesions of different histologic types are separate primaries. However, for separate tumors of duct and lobular, we report as a single primary. Since we now have a combination code for duct and other types of ca, do we report as a single primary or continue to report as separate primaries?

For tumors diagnosed prior to 2007:

When there are two breast tumors, one mucinous, the other duct carcinoma, report as two primaries when the pathologist's opinion clearly states that there are separate primaries.

If there is no such information from the pathologist, the two tumors must be separate with clear (negative) margins to be reported as two primaries. Otherwise, report as one primary.

The ICD-O-3 combination codes are not intended to combine tumors of different histologic types.

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.

Multiple Primaries (Pre-2007)--Melanoma: Many melanoma patients have multiple occurrences over time that are not called recurrent and often are even in the same skin subsite, some in situ only and others alternating between in situ and invasive. Should these multiple occurrences really be new primaries?

For tumors diagnosed prior to 2007:

Unless it is stated to be a RECURRENT or METASTATIC melanoma, record each melanoma as a separate primary when:

1. The occurrences are more than two months apart.

2. The fourth digit of the ICD-O topography code for skin [C44._] is different .

3. The first three digits of ICD-O-3 morphology code are different.

4. An in situ melanoma is followed by an invasive melanoma.

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.

Multiple Primaries (Pre-2007): Would osteosarcoma of the right arm diagnosed four years after malignant fibrous histiocytoma, also in the right arm, be a second primary when the physician states, "the patient's disease progressed to sarcoma after radiation was administered?"

For tumors diagnosed prior to 2007:

The osteosarcoma is a second primary. The first three digits of the histology codes are different: 8830 [Malignant fibrous histiocytoma] and 918_ or 919_ [Osteosarcoma]. In addition, the diagnoses are four years apart. According to SEER rules, these are separate primaries.

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
