20000512 EOD-Extension/EOD-Lymph Nodes--Kaposi Sarcoma: What code is used to represent this field for a Kaposi sarcoma with no skin lesions but positive lymph node and bone marrow biopsies?

Code the EOD-Extension field to 13 [Visceral (e.g., pulmonary, gastrointestinal tract, spleen, other)], because of the positive bone marrow. Code the EOD-Lymph Nodes field to 3 [Both clinically enlarged palpable lymph nodes (adenopathy) and pathologically positive lymph nodes], for the pathologically positive node.

Note: Potential revision of the extension scheme will be referred to SEER Medical Advisory Group (SMAG).

 Sarcoma N/A 2000
20000430 Histology (Pre-2007)--Colon: What code is used to represent histology when the surgeon describes a sessile polyp and the final path diagnosis is stated as: "Rectal sessile polyp: Invasive moderately differentiated adenocarcinoma" (pathologist does not state that it is "arising in a sessile polyp")?

For tumors diagnosed prior to 2007:

Code the Histology field to 8210/3 [adenocarcinoma arising in a polyp]. The structure in which this adenocarcinoma is arising, is a polyp.

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.

 Colon Histology 2000
20000256 EOD-Size of Primary Tumor--Melanoma: How do you code tumor size for a melanoma diagnosed by a positive lymph node biopsy when the primary site is coded C44.9 because no primary site was identified? See discussion. Should the size be 000 because no primary was found or 999 for unknown?

For cases diagnosed 1998-2003:

Code the EOD-Size of Primary Tumor field to 000 [No mass; no tumor found] when primary site is coded to C449.

 Melanoma N/A 2000
20000508 EOD-Extension--Cervix: Should this field be coded to 11 [minimal microscopic stromal invasion] or 12 [microinvasion] when there is only a statement of "microinvasion" but no measurements describing the level of involvement given?

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 12 [microinvasion] when there are no depth of invasion measurements given.

Code the EOD-Extension field to 11 [minimal microscopic stromal invasion] when there is a statement of "minimal STROMAL invasion."

 Cervix Uteri N/A 2000
20000431

Surgery Fields--Multiple sites: What code is used to represent these fields for the following surgical procedures?

1. Tongue, NOS - Hemiglossectomy with lymph node dissection

2. Choroid - Eye enucleation

3. Vulva, NOS - Vulvectomy with bilateral lymph node dissection

4. Gallbladder - Cholecystectomy

5. Lung - Laminectomy with partial removal of tumor

For cases diagnosed 1/1/03 and later:

1. Code Surgery of Primary Site to 30 and Scope of Regional Lymph Node Surgery to 3.

2. Code Surgery of Primary Site to 41.

3. Code Surgery of Primary Site to 40 and Scope of Regional Lymph Node Surgery to 3.

4. Code Surgery of Primary Site to 40.

5. Code Surgical Procedure of Other Site to 4.

 N/A N/A 2000
20000420 Date of Diagnosis--All Sites: Is it better to estimate the month in the date of diagnosis field using the re-excision pathology report date or code the month to unknown if the only available information is the re-excision date? See discussion.

The only available information is the following pathology report:

On 7/18/00 a wide excision of the primary lesion is done. The report reads, "Lesion approximately 1 cm. Residual superficial spreading malignant melanoma with deepest penetration 4 mm."

Code the Date of Diagnosis field to 07/2000 for this case. Estimate the month of diagnosis whenever possible.

Given the usual delay between the initial excision of the lesion and a wide excision for a melanoma, estimate the month of diagnosis as July.

 N/A Date of diagnosis 2000
20000478 Multiple Primaries (Pre-2007)--Breast: When a breast cancer is treated with less than a total mastectomy and more than 2 months later a tumor of the same histology is diagnosed in the same breast with no statement of "recurrence," is this a new primary?

For tumors diagnosed prior to 2007:

Count as 2 primaries when a subsequent malignant breast tumor is diagnosed more than 2 months later unless stated to be a recurrence. For cases diagnosed after 1/1/94, an in situ followed by an invasive breast cancer is counted as two primaries even if stated to be a recurrence.

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.

 Breast N/A 2000
20000247 EOD-Pathologic Extension--Prostate: If there is residual tumor in the distal urethra on prostatectomy, does that mean there is distal urethral margin involvement? See discussion.

2/98 Prostate bx: Right apex, right mid and right base positive for adenocarcinoma.

6/1/98 Radical retropubic prostatectomy w/ bilateral pelvic lymph node dissection. Pathology: Residual adenocarcinoma in distal urethra, right lateral sections and posterior lobe. Right apical margin, other margins, seminal vesicles, and 7 pelvic LN negative for malignancy.

For cases diagnosed 1998-2003:

For the example above, code the EOD-Pathologic Extension field to 34 [extending to apex] because most of the right side is involved.

The pathology report says all margins are free. The comment on residual tumor in the urethra, meant the first surgery did not completely remove tumor tissue from the urethra, it does not mean that tissue is at the margin.

 Prostate N/A 2000
20000486 EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined/Surgical Procedure of Other Site--Kaposi Sarcoma: How do you code these fields for a groin mass excision containing 4 lymph nodes for a Kaposi sarcoma case that presented with multiple skin lesions?

Code the EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined fields to 99 99 for Kaposi cases that present systemically and for those that present in more than one site (which includes cases with more than one skin subsite involved at diagnosis). There are no "regional" lymph nodes for such cases. This represents a majority of currently diagnosed Kaposi cases. However, for localized Kaposi cases, you can count the number of regional lymph nodes positive and examined if the primary site selected has a regional lymph node chain(s) associated with it (e.g., soft palate, hard palate, or a skin subsite).

For cases diagnosed 1/1/2003 and after: Code the groin mass excision in the Surgical Procedure of Other Site field to 1 [Non-primary surgical procedure performed; Non-primary surgical resection to other site(s), unknown if whether the site(s) is regional or distant].

 Lymph nodes, Sarcoma N/A 2000
20000849 Primary Site--Lymphoma: How should you code the primary site for a lymphoma that presents with involvement of an extranodal site and regional lymph nodes? See discussion.

1. Lymphoma involves the spleen and the splenic lymph nodes.

2. MALT Lymphoma involves the stomach and the gastric and iliac lymph nodes.

1. Code the Primary Site field to C42.2 [spleen].

2. Code the Primary Site field to C16._ [stomach].

When lymphoma presents in an extranodal site and in the regional lymph nodes for that extranodal site, code the Primary Site field to the extranodal site. The typical disease process is that lymphoma can spread from an extranodal organ to its regional lymph nodes. It cannot metastasize from the regional lymph node to the extranodal organ. The exception to this would be if the lymph nodes presented as one large mass that extended into the regional organ.
