20061071 CS Extension--Lymphoma: In the absence of physician staging, is an "enlarged" spleen seen on CT coded as involvement of the spleen for lymphoma cases?

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 spleen involvement when the only evidence is an enlarged spleen.

When imaging is the only diagnostic tool (no biopsy or splenectomy), spleen involvement is based on the presence of nodules and not on enlargement. Splenic enlargement alone (by physical exam or imaging) is insufficient to support involvement of spleen.

20061036 CS Extension--Lymphoma: For lymphoma cases, can extension be coded to 80 [Nodular involvement of lungs] based on imaging or operative findings when there is no positive statement of involvement? See Discussion.

Specifically, CS Ext code 80 includes nodular involvement of the lungs. The CT report for this patient states that the lungs are nodular. Is that enough to use code 80? Can the liver be coded as involved based on the operative findings?

Scenario: The patient was diagnosed with lymphoma. The CT showed pulmonary nodules. The pt had an exploratory laparotomy with a positive mesenteric LN bx and a positive ileocecectomy. The operative findings included a nodular liver. No staging was done by the oncologist and he has the pt on CHOP-R.

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.

Extension code 80 can be assigned based on imaging or operative findings as in the lymphoma case described above. The fact that this extension was not based on pathological evidence is captured in the evaluation code. Assign CS/TS Ext-Eval code 0 [No staging laparotomy done. No autopsy evidence used (clinical)].

20061099 CS Extension--Lung: If only a "single" cytology is performed on pericardial fluid and it is negative, can Note 6 B, which states that pleural effusion [code 72] is coded as malignant unless there are "multiple" negative cytologies, be used to infer that the pericardial fluid should also be coded as involvement?

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.

No, do not apply the instructions for pleural effusion to pericardial effusion. Do not code a pericardial effusion proven negative by cytology in CS Extension.

20091007 CS Extension--Lung: How is this field coded for a tumor in the right middle lobe with extension to the bronchus intermedius?

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.

Assign CS extension code 20

[Extension from other parts of lung to main stem bronchus, NOS

(EXCLUDES superficial tumor as described in code 11)

Tumor involving main stem bronchus greater than or equal to 2.0 cm from carina (primary in lung or main stem bronchus)].

A right middle lobe tumor that extends to the bronchus intermedius is one that is extending to the main stem bronchus from another part of the lung. The bronchus intermedius is the lower part of the main stem bronchus on the right. It is more than 2.0 cm away from the carina.

20061130 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.

20081007 CS Extension--Lung: How is "subpleural extension" 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.Subpleural extension means that the tumor extends to the subpleural space, but the pleura itself is not involved. Assign the appropriate extension code based on the other facts for the case. Do not code pleural involvement.

 2008
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.

20081057 CS Extension--Lung: Chest CT shows segmental atelectasis (CS EXT code 40), but patient had Left Lower Lobe lobectomy/Lymph Node dissection with no involvment outside the lobe (pleura and all margins neg). Do we still code the atelectasis (CS Ext 40) over confined to lung (CS EXT code 10)?

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.Assign CS Extension code 40 [Atelectasis/obstructive pneumonitis that extends to the hilar region but does not involve the entire lung (or atelectasis/obstructive pneumonitis, NOS)].

CS extension code 10 does not apply when any condition described in codes 20-80 exists.

 2008
20061057 CS Extension--Lung: Can extension be coded to 10 (Tumor confined to one lung) when either an autopsy or a CT scan describes the tumor as a mass of a specified size located in one lobe of the lung without any description of extension and no available TNM provided? See Discussion.

Example 1: Lung primary within the right lower lobe described clinically as greater than 3 cm on scan but was found to be 3 cm at autopsy.

Example 2: CT scan February shows 2 cm mass in RUL.

In both cases, the only tumor description was the size of tumor without any information regarding extension.

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.

Yes, assign code 10 [Tumor confined to one lung] for a mass in one lobe when none of the descriptions in codes 11 to 80 are documented.

20051092 CS Extension--Kidney: When an incidentally found 5 cm mass discovered on a CT scan during a work-up for colon carcinoma is stated to be consistent with renal cell ca, should the case be staged as localized or unknown when no other information is available related to a work-up for the kidney primary?

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 what is known. In the example above, the tumor size and the extension are known and can be coded. The information is limited, but not completely missing.

Code what you DO know rather than coding nothing. Any metastases from the kidney would have been discovered during the workup of the rectal cancer.
