CS Site Specific Factor--Prostate: How is SSF 6 coded for this site when there is only one Gleason number documented and the number is less than 5 (e.g., Gleasons 3)?
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 999 [unknown or no information]. Note 1 was revised in September 2006 to clarify this situation.
Note 1 states "If only one number is given and it is less than or equal to 5, code the total score to 999, unknown or no
Chemotherapy: If a physician does not document the reason chemotherapy was given concurrently with radiation therapy, should it be assumed to have been used as a radiosensitizer or radioprotectant and then, per SEER chemotherapy coding instruction 2, ignore coding the chemo agent as treatment?
Do not assume that a chemo agent given with radiation therapy is a radiosensitizer. Seek additional information.
Compare the dose given to the dose normally given for treatment. When chemotherapeutic agents are used as radiosensitizers or radioprotectants, they are given at a much lower dose.
Histology (Pre-2007): How is "adenocarcinoma, diffuse type, with signet ring features" coded?
For tumors diagnosed prior to 2007:
Code 8490 [Signet ring cell carcinoma]. Histology coding Rule 7 is the only rule that applies to this diagnosis. Assign the numerically higher ICD-O-3 code.
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.
Reportability/Behavior--Skin: Is an "atypical fibroxanthoma (superficial malignant fibrous histiocytoma)" with an ICDO-3 histology code of 8830 reportable with a behavior code of 3 or is it nonreportable with a behavior code of 1?
Yes, "atypical fibroxanthoma (superficial malignant fibrous histiocytoma)" is reportable. The information in parentheses provides more detail and confirms a reportable malignancy.
CS Lymph Nodes--Lung: Do modifying terms such as "borderline" affect whether lymph nodes are coded as involved when they are used in conjunction with the descriptors listed in Note 2 (i.e., mass, adenopathy or enlargement) for lung primaries? See Discussion.
Lung primary: CT states "borderline" enlarged hilar lymph nodes. Note 2 in the Lung schema under CS Lymph Nodes does not address qualifiers.
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.
Do not code the hilar lymph nodes as involved in this case. "Borderline" enlarged hilar lymph nodes do not meet the clinical criteria for enlargement.
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.
CS Extension--Lung: How is extension coded if there is only one cytology done on a pleural effusion that is negative for carcinoma (but shows an exudate) and there is no clinical assessment of the pleural effusion found in the medical record? See Discussion.
CS lung extension note 6 provides instructions from the SEER manual and also from the AJCC manual. Per SEER manual, "ignore the effusion that is negative for tumor." Do we ignore the pleural effusion for the case in question because it was negative? Per 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." For the case in question, pleural fluid was examined only once and clinical judgment is not available. As a SEER registry, do we follow the SEER portion of the note and ignore the pleural effusion? Or do we code extension as involving pleural effusion because it was an exudate?
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.A single negative pleural effusion by itself does not impact the coding of extension.
The SEER note does not alter the AJCC note and the AJCC note does not alter the SEER note. They are two separate statements from two separate staging authorities. Registries follow both notes. For this case, ignore the pleural effusion because there is no clinical judgment available and there was only one cytology on the effusion.
Reportability--Melanoma: Is the following reportable? See Discussion.
PATH: Skin, Lt back exc bx: compound nevus with severe cytoarchitectural atypia and regression. Comment: due to overlap of morphology between MM and nevi with severe atypia, and since there's evidence of regression, consideration for re-excision may be considered if clinically indicated.
The final diagnosis, compound nevus with severe atypia, is not reportable. This diagnosis is not listed in ICD-O-3.
Histology (Pre-2007)--Head & Neck: How is a "sinonasal undifferentiated carcinoma (SNUC)" coded?
For tumors diagnosed prior to 2007:
Code histology to 8020 [carcinoma, undifferentiated]. "Sinonasal" refers to anatomic location of primary site not histology.
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.
