Report Question ID Question Discussion Answer Year
20061134 Reportability: Is an AIN III that arises in perianal skin, skin tags or condyloma acuminatum reportable or must an AIN III arise in the anus or anal canal in order to be reportable?

AIN III arising in perianal skin [C445] is not reportable.

AIN III [8077/2] of the anus or anal canal is reportable.

20061014 Surgery of Primary Site--Lung: Is this field coded to 30 [Resection of lobe or lobectomy] or 33 [Lobectomy with mediastinal lymph node dissection] when a lobectomy specimen includes 2 AP window lymph nodes? See Discussion.

LUL lobectomy: 1.7cm apical tumor, DX=mod well diff subpleural SCC, with involvement of pleural surface. 3 peribronchial LN neg and 2 AP window LNs neg. Stage T2N0.

1. No lymph node dissection or sampling was stated to be done

2. The lobectomy specimen contained the LNs

3. Scope of regional LN surgery is coded

Would the surgery to primary site code 30 or 33?

 Code surgery of primary site to 30 [Resection of lobe or lobectomy]. According to the information provided, there was no lymph node dissection in this case. The 2 AP window nodes were obtained as part of the lobectomy specimen. 2006

Reportability: Are glomus jugulare tumors reportable?

Begining with cases diagnosed 2021, glomus jugulare tumor, NOS is reportable. It is listed in ICD-O-3.2 with a behavior code of /3.

20061055 CS Lymph Nodes--Colon: What criteria is used to distinguish between code 30 [Regional lymph nodes, NOS] and 80 [Lymph nodes, NOS] when positive lymph nodes are removed during a colon resection but the lymph node location is not stated? See Discussion.

Example 1: Descending colon excision: Metastatic adenocarcinoma in 8 of 9 lymph nodes.

Example 2: Hepatic flexure and en bloc resection of liver. Adenocarcinoma in 3 of 10 lymph nodes.

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 positive nodes included with the resected specimen as regional lymph nodes, NOS when the location is not stated. See number 3.e under the general instructions for coding CS lymph nodes.

Based only on the information provided, code CS lymph nodes 30 [Regional lymph nodes, NOS] for both examples.

20061008 Histology (Pre-2007)--Corpus uteri: How is a polyp with "endometrial carcinosarcoma (Malignant Mixed Mullerian tumor), endometrial adenocarcinoma, and some areas of high grade spindle sarcoma" coded? See Discussion. The path report for the TAH stated the endometrium contained an endometrial polyp measuring 6x3x3cm. Within the polyp there was endometrial carcinosarcoma (Malignant Mixed Mullerian tumor), endometrial adenocarcinoma, and some areas of high grade spindle sarcoma. There is no myometrial invasion by the tumor. (The Endometrial bx before surgery was positive for Malignant Mixed Mullerian tumor.)

For tumors diagnosed prior to 2007:

Assign code 8980 [Carcinosarcoma, NOS]. According to the WHO Classification of tumors, Malignant mullerian mixed tumor is a synonym for carcinosarcoma and carcinosarcoma is now the preferred terminology rather than malignant mixed Mullerian tumor.

Carcinosarcoma has both malignant epithelial and mesenchymal components. The epithelial component is usually glandular (adenocarcinoma in this case). The mesenchymal component is usually sarcoma (as in this case).

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.

20061104 Reportability/Behavior--Hematopoietic, NOS: Is a "myelodysplastic/myeloproliferative disease, unclassifiable" coded to 9975 with a behavior code of 3 as indicated in the WHO blue book on "Tumours of Haematopoietic and Lymphoid Tissues" or is it not abstracted because it has a behavior code of 1 which means the case is not reportable?

For cases diagnosed prior to 1/1/2010:Code MDS/MPD U to 9975/3 [Myelodysplastic/myeloproliferative disease, unclassifiable]. Change the behavior code to /3 according to ICD-O-3 Rule F. The case is reportable.

The WHO book is more recent and gives a specific code for this new hybrid category of the WHO/REAL classification.

For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.

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.

20061052 Diagnostic Confirmation--Leukemia: How is this field coded when the clinician confirms that the diagnosis of CML is based on a combination of the clinical picture and positive cytogenetic studies?

Assign code 1 [Positive histology]. For leukemia only, assign code 1 for positive hematologic findings including peripheral blood smears, CBCs and WBCs.

Cytogenetics studies would have been done on blood. Therefore, histology provided diagnostic confirmation as it would with smear, bone marrow, or other special study of blood cells.

20061056 CS Lymph Nodes--Colon: Are positive paracecal lymph nodes for cecal primaries coded to 10 [paracolic] or code 20 [cecal: anterior (prececal), posterior (retrocecal); NOS]?

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 code 20 [Regional lymph node(s) for specific subsites]. Paracecal means near the cecum. Paracecal lymph nodes are regional nodes for the cecum and not for other colon subsites.

Reportability--Brain and CNS: Is benign neural tissue compatible with a glioneuronal hamartoma of the cerebellopontine angle reportable?

No. A glioneuronal hamartoma is not neoplastic and not reportable. See page 2 of the 2004 SEER Program Coding and Staging manual for the list of reportable brain/CNS tumors. There is no ICD-O-3 code for hamartoma.
