Report Question ID Question Discussion Answer Year
20061062 Reportability: Is a "pleomorphic hyalinizing angiectatic tumor of soft parts (PHAT)" reportable if the case has a TNM stage assigned and is stated by the pathologist to be a rare intermediate grade sarcoma?

Pleomorphic hyalinizing angiectatic tumors of the soft parts are not reportable.

According to our pathologist consultant, PHAT is a borderline malignancy (/1). While the true nature of these tumors is under debate (reactive vs. neoplastic), so far none have metastasized.

20061032 Behavior--Head & Neck: Should the SEER IF_Morph_3 edit be modified because it does not allow a behavior code 2 with histology 8941 [carcinoma in a pleomorphic adenoma] for a parotid primary?

Code the behavior as 2 and over-ride the edit. The edit is there to flag unusual combinations. Once you have verified that the behavior is coded correctly, over-ride the edit.

The surgeon stage of T2 is based on size of tumor, the TIS is based on behavior. Code according to pathologically confirmed TIS.

20061044 CS Site Specific Factor--Head & Neck: If a lymph node dissection of the neck reveals that 1/24 lymph nodes is positive and the positive 5.6 cm lymph node extends throughout levels II-IV, how are the SSF 3 (status of levels I-III lymph nodes) and SSF4 (status of levels IV-V lymph nodes) fields coded?

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.According to the CS Steering Committee, code 999 for SSF 3 and SSF 4. In this case, do not make assumptions about which level of lymph nodes were involved.

20061063 CS Extension--Lung: Do notes 6A and 6B in the 2004 SEER manual offer conflicting instruction for determining the significance of pleural effusion for this primary site? See Discussion.

1. Is note B to be used to modify or change what note A states?

Does note B state -- If a pleural fluid bx(s) is negative; but the fluid is bloody and/or is an exudate, and clinical judgment indicates the effusion is related to tumor -- use code 72?

If a pleural effusion is biopsied should the pathology report state the color of the pleural fluid or is an exudate? (Training issue)

2. Do the following clinical findings impact the clinical evaluation of involvement for a pleural effusion? If yes, why? (Training issue(s))

a. Heart problems?

b. The location of the pleural effusion?

i. Bilateral pleural effusion is noted; tumor in Rt or Lt lung only?

ii. Bilateral pleural effusion is noted; tumor in both lungs?

iii. Pleural effusion is noted on the opposite side from the tumor?

iv. Pleural effusion is on same side as the tumor?

SUPPORTING CS MANUAL DOCUMENTATION

Note 6: Pleural Effusion.

A. Note from SEER manual: Ignore pleural effusion that is negative for tumor. Assume that a pleural effusion is negative if a resection is done.

B. Note from AJCC manual: Most pleural effusions associated with lung cancers are due to tumor. However, there are a few patients in whom multiple cytopathologic examinations of pleural fluid are negative for tumor.

In these cases, fluid is non-bloody and is not an exudate. When these elements and clinical judgment dictate that the effusion is not related to the tumor, the effusion should be excluded as a staging element and the patient should be staged T1, or T2, or T3.

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.

1. Note B does not modify or change note A. Note B is explaining when an effusion should not be used to determine the stage. Pleural effusions are evaluated by cytology, not biopsy.

2. If relevant, the clinician should document the fact in the medical record. Heart problems can cause non-malignant pleural effusions (that are disregarded for staging). Pleural effusion will almost always be around the lower lobes due to gravity, but may envelop an entire lung. Pleural effusions can be unilateral or bilateral regardless of the location of the tumor, but are usually on the side where the tumor is.

Reportability--Ovary: Is an "aggressive adult granulosa cell tumor with one of two lymph nodes positive for metastatic granulosa cell tumor" reportable?

Malignant granulosa cell tumor is reportable. The case described above is malignant as proven by metastasis to the lymph node.

20061142 Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Skin: How many cases are to be abstracted and how is the histology field(s) coded for cases in which a fibrosarcoma arises in or transforms from a dermatofibrosarcoma protuberans? See Discussion.

1. If the fibrosarcoma occurs after DFP, and is called metastatic, is it a recurrence or is it a new primary? Example: Pt diagnosed in 7/05 with a high grade fibrosarcoma arising in a dermatofibrosarcoma protuberans. The path indicated "The presence of high grade fibrosarcoma, the extent of the tumor necrosis and the mitotic rate are all adverse prognostic findings that indicate a significant risk for mets." The patient had a recurrence in 8/06 called a low grade fibrosarcoma mets from prev." The DFP code is 8832/3 and a fibrosarcoma code is 8810/3. Our pathologist feels that the fibrosarcoma is a more aggressive tumor so should the case be coded to the 8810/3.

2. If DFSP has areas of fibrosarcoma, should it be coded to the latter because it is more aggressive? Example: Skin and subcutaneous tissue reads: Low grade sarcoma - tumor extends to margin. Comment: "Although the predominant pattern of this tumor is consistent with dermatofibrosarcoma protuberans, focal presence of hypercellularity and increased mitotic figures suggest transformation to Grade I fibrosarcoma. This progression, although focal, carries an increased risk of mets over classic DFSP. Code to 8810/31?

For tumors diagnosed prior to 2007:

Code histology to 8832/3 [Dermatofibrosarcoma protuberans] for both cases. DFSP with transformation to fibrosarcoma and DFSP with areas of fibrosarcoma are coded to 8832/3.

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.

20061001 2004 SEER Manual Errata/CS Lymph Nodes--Head & Neck: On page C-353, in the supraglottic larynx schema, there is no mention of Level IV nodes in the CS Lymph Node codes.

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.The CS Steering Committee is aware of this issue and is working to resolve it.

20061053 Diagnostic Confirmation: How is this field coded for a case with a cytology that is suspicious for ductal carcinoma and the clinical diagnosis is carcinoma? See Discussion. SINQ 20031152 states that histology for this type of case is to be coded per the clinical diagnosis of "carcinoma." Does it follow then that Diagnostic Confirmation is to be coded 8 (clinical diagnosis only)? Would we code Diagnostic Confirmation differently if the clinician stated that the diagnosis of malignancy was confirmed by the suspicious cytology?

Code diagnostic confirmation as 8 [clincial diagnosis] when there is a suspicious cytology and a physician's clinical diagnosis. Do not accession cases with only suspicious cytology.

Code diagnostic confirmation as 8 when the clinician's diagnosis of malignancy is confirmed by the suspicious cytology. It is still a clinical diagnosis made by the physician using the information available for the case.

20061123 Reportability--Colon: Is a pathologically confirmed "tubulovillous adenoma with high grade dysplasia" reportable if clinical diagnosis at the time of the subsequent re-biopsy states "follow-up for colon polyps with ca in situ"? See Discussion. SINQ 20000245 states that high grade dysplasia is not synonymous with behavior code 2 (in situ). However, the 2004 SEER manual states that "cases clinically diagnosed are reportable. If the physician treats a patient for cancer in spite of the negative biopsy, accession the case." A pathologic diagnosis has priority over a clinical diagnosis. According to the pathologist, this case is not reportable. A re-biopsy is not treatment. 2006
20061114 Histology (Pre-2007)--Melanoma: How is a "plaque-like nodular spitzoid malignant melanoma" coded?

For tumors diagnosed prior to 2007:

Code histology to 8721 [nodular melanoma]. Essentially, "plaque-like nodular spitzoid malignant melanoma" is nodular melanoma. Code 8721 is the most specific ICD-O-3 histology code available for this diagnosis.

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.
