Report Question ID Question Discussion Answer Year
20031202 Surgery of Primary Site--Head & Neck: How is this field coded for a surgery titled "Parotidectomy with facial nerve dissection"? See Description. If the operative report is not titled "total parotidectomy," can we assume that less than total parotidectomy was done? Can we assume that "facial nerve dissection" and "facial nerve monitoring" are other ways of stating "facial nerve spared"?

Use the best information available to determine whether or not all of the parotid has been removed. It is important to read the entire operative report and review the content of the pathology report. The Op report will usually include wording about how much was removed, and this can be confirmed by the path report. Do not make assumptions about the extent of the surgery based solely on the title used on the operative report.

For cases diagnosed 1998-2003: Code 30 [less than total parotidectomy] can be used when the parotid is not totally removed, but the exact type of partial parotidectomy cannot be determined. "Facial nerve monitoring" and "Facial nerve dissection" are synonymous with "facial nerve sparing."

20031153 Laterality/Multiple Primaries (Pre-2007)--Ovary: Are ovarian primaries with bilateral involvement always coded to laterality 4 (bilateral)? See Description. Example: "Right ovary with mass replacing majority of ovarian tissue consistent with serous adenoca. Lt ovary with foci of adenoca." No specific statement of primary. Can we assume that the malignancy originated in the right ovary since it is more extensively involved or should laterality be coded 4 because both ovaries have tumor?

For tumors diagnosed prior to 2007:

If one ovary is listed as the primary site, code laterality to that ovary. The example above is one of those times when you would code to the single ovary. The issue of one or both ovaries being involved is handled in staging.

Abstract the example above as a single primary with code 1 [Right] for laterality.

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.

20031208 EOD-Extension--Corpus uteri: How should EOD extension be coded when the pathology report shows adenocarcinoma arising in the endometrium with the statement "no invasive carcinoma identified?" For cases diagnosed 1998-2003: Code endometrial cancer with no invasion to EOD extension code 11 [Confined to endometrium (stroma)]. "No invasion" most likely means no invasion of the myometrium. 2003

Histology/Reportability/Behavior Code--Testis: Is a mature teratoma that is metastatic to lymph nodes reportable? See Description.

Pathology report states, "Histologic sections reveal lymph node metastases, consisting predominantly of mature teratoma. In addition, there are cells scattered through the fibrous stroma which exhibit mild cytologic atypia but have low N:C ratios. The largest metastasis grossly measures 10cm. In addition extracapsular extension is identified. Diagnosis: Lymph Nodes--Metastatic Testicular Carcinoma Involving Multiple Lymph Nodes." The morphology code for mature teratoma is 9080/0. The pathologist does not classify this as an immature teratoma (9080/3). Is this reportable?

Yes, this metastatic teratoma is reportable.

This is a malignant teratoma by virtue of the lymph node metastases. Code the histology as 9080/3 [Teratoma, malignant, NOS]. Primary site is testis [C62_].

20031015 EOD-Extension--Lymphoma: How is the following guideline of "any mention of lymph nodes is considered indicative of involvement" applied for EOD-Extension of lymphoma cases when there is a discrepancy between physicians as to the stage at diagnosis? See discussion. A biopsy of mesenteric nodes confirmed lymphoma. A bone marrow biopsy was negative. A CT of the chest indicates "small mediastinal and bilateral hilar nodes, but without convincing adenopathy." The case was Stage 2 per the oncologist and Stage 3 per the surgeon's TNM form.

For tumors diagnosed 1998-2003:

Based on the information provided for this example, the lymphoma involves one site, mesenteric nodes. Code EOD extension as 10 [Involvement of a single lymph node region].

The statement "For lymphomas, any mention of lymph nodes is indicative of involvement" refers to the terms in the paragraph above it on page 8 of the EOD manual: Palpable, enlarged, visible swelling, shotty, lymphadenopathy. While these terms are ignored for other malignancies, they should not be ignored for lymphomas. None of these terms apply to the example provided here. According to the CT, the mediastinal and hilar nodes are "small" "without convincing adenopathy." In other words, the mediastinal and hilar nodes are negative.

20031204 Surgery of Primary Site--Breast: How is this field coded for cryosurgery of the breast?

For cases diagnosed 2003 and later: For cryosurgery alone, without a pathology specimen, assign site-specific surgery code 19 [Local tumor destruction, NOS]. Cryosurgery, cryotherapy or cryoablation uses extreme cold to destroy the tumor cells.

If a specimen is sent to pathology use code 20 [Partial mastectomy, NOS] rather than code 19.

If cryosurgery is followed by further surgery, do not use code 19.

20031146 EOD-Size of Primary Tumor--Breast: How do we code this field when there is a difference between the size of the tumor mentioned in the gross (i.e., macroscopic description) and the comment sections of a pathology report? See Description. Path Macro Summary states size as 1.5 cm. The path comment states "largest area of tumor seen is 1.5 cm. However, 8 of the nearly contiguous sections are involved with an estimated 2.4 cm area of involvement." For cases diagnosed 1998-2003: Code the size of the largest area of tumor from the path macro summary. For the example provided, code the size as 015 [1.5 cm]. In this case, the additional sections of tumor described in the path comment do not seem to represent pieces of one larger tumor. The 2.4 cm estimated area of involvement was determined by adding together noncontiguous tumor sections. According to the CAP protocol for breast, Note J "When 2 or more distinct invasive tumors are present, each is separately measured...they are not combined into a single larger size." 2003
20031091 EOD-Pathologic Extension--Prostate/Lymphoma: How is this field coded for a prostatic lymphoma? For cases diagnosed 1998-2003: Do not code the prostate pathologic extent of disease field for prostatic lymphoma. Leave the path extension for prostate field blank. Code the extent of disease using the lymphoma scheme. Use ONLY the lymphoma scheme - do NOT try to code both lymphoma and prostate extension fields for prostatic lymphoma. 2003

Primary site: How is this field coded for a malignant spindle cell neoplasm in a subcutaneous mass of the right knee? See Description.

The pathology report says: Right knee tumor:

A. discrete subcutaneous mass 3.5x5.2x1.4 cm malignant spindle cell neoplasm (see Comment)

B. A focus of subcutaneous malignant neoplasm is identified in the superior resection margin.

C.All other margins are clear.

The comment mentions that the specimen has been sent to Mayo Clinic and the Mayo clinic consult says, "we still believe that the diagnosis of spindle cell carcinoma is correct. Obviously the differential diagnosis involves melanoma and sarcoma also. The results of the immunoperoxidase stains strongly support the prior diagnosis of a carcinoma."

Code the site to C49.2 [Connective, subcutaneous and other soft tissues of lower limb and hip]. The site is a subcutaneous mass. C49 with 8032/3 will not be impossible following the next updates to the SEER edits.

Primary Site/Histology (Pre-2007)--Unknown & ill-defined site: How are these fields coded for a markedly atypical high grade malignant neoplasm diagnosed by a fine needle aspiration of a large iliac mass, right buttock area? See Description.

The diagnosis was made in Oct. 2002 by a CT guided fine needle aspiration of a large iliac mass, right buttock area. The cytology report says:

a. positive for malignant cells, markedly atypical high grade malignant neoplasm.

b. It is impossible to tell from this aspiration biopsy whether or not this represents a high grade sarcoma or a high grade carcinoma, but our consensus opinion is that this lesion is a high grade carcinoma.

The combination of soft tissue topography and carcinoma morphology is Impossible by SEER edits. How should we code this?

For tumors diagnosed prior to 2007:

Code the site to C76.3 [Pelvis, NOS]. Code the histology to 8010/34 [Carcinoma, NOS, high grade].

Unless there is better information available regarding the site, assign C76.3. The information provided above does not indicate the exact site of the mass.

Code the histology based on the consensus opinion stated above.

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.
