Report Question ID Question Discussion Answer Year
20061133 Terminology, NOS--Melanoma: Is a diagnosis of melanoma "with associated intradermal nevus" coded the same as a melanoma "arising in a nevus"? Yes, melanoma "associated with" a nevus and melanoma "arising in" a nevus are synonymous. 2006
20061131 CS Lymph Node Examined--Lung: How is this field coded when a mediastinoscopy and lobectomy are performed and the pathology report indicates multiple lymph node fragments were removed as biopsy specimens and the lobectomy specimen revealed 3 interlobar 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 the CS Lymph Node Examined field to 98 [number unknown] because the biopsy information is not clear and as a result you do not know how many lymph nodes were examined.

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.

20061129 Multiple Primaries (Pre-2007)--Head & Neck: How many primaries are abstracted if a patient has bilateral involvement of tonsils with the same histology (e.g. squamous cell carcinoma)? See Discussion. Patient was initially found to have mass on right tonsil. Biopsy of right tonsil on June 16 showed invasive carcinoma, favor squamous cell. On July 17 patient underwent right neck dissection, radical resection of right tonsil tumor and left tonsillectomy. Right tonsil showed squamous cell carcinoma, poorly differentiated. Left tonsil showed squamous cell carcinoma, poorly differentiated. Microscopic report stated: Right tonsil: Invasion of deep peritonsillar tissue and skeletal muscle. Sections of left tonsil demonstrate squamous cell ca focally distributed in the tonsil, predominantly in situ, but with focal microscopic invasion. Path staged each tonsil specimen. Right tonsil was T2N1. Left tonsil was T1Nx.

For tumors diagnosed prior to 2007:

Code as two primaries. Squamous cell carcinoma diagnosed in both left and right tonsils are multiple primaries unless one is stated to be metastatic from the other.

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.

 2006
20061128 Marital Status: Is marital status coded to 2 [married] if the patient is legally married to a same-sex spouse (e.g., patient has a Canadian spouse and in Canada, same-sex marriages are legal)? Code marital status for same-sex persons based on the legal status. For the case example above, assign code 2 [married]. 2006
20061127 CS Lymph Nodes--Esophagus: Is a resected positive "periesophageal nodule" coded as an involved lymph node for an esophagus primary? See Discussion. Per SINQ 20000846: Each gross nodule of metastatic carcinoma in the fat surrounding an organ is counted as one positive regional lymph node. SINQ 2000846 applied to EOD. Can this concept be used for Collaborative Stage?

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.

For cases diagnosed on or after January 1, 2004:

Search for additional information on the "nodule." Review the gross and microscopic descriptions to determine whether or not the nodule is a lymph node. If it is not possible to obtain further information, apply the downstaging rule and select the Extension or LN code that results in the lower category.

20061126 Histology--Leukemia: How is a "plasmacytoid dendritic cell leukemia/lymphoma" coded when it is discovered on a bone marrow biopsy for a patient who presented with multiple enlarged lymph nodes and the discharge diagnosis was Type 2 plasmacytoid dendritic cell leukemia?

For cases diagnosed prior to 1/1/2010:

The best code currently available for this entity is 9727/3 [precursor cell lymphoblastic leukemia].

The WHO classification refers to this as "Blastic NK-cell lymphoma." The 2005 WHO-EORTC classification for cutaneous lymphomas states that blastic NK-cell lymphoma may be derived from a plasmacytoid dendritic cell precursor. They suggest more appropriate terms for this condition may be "CD4+/CD56+ hematodermic neoplasm," and "early plasmacytoid dendritic cell leukemia/lymphoma." According to WHO, this is a rare form of lymphoma.

Willemze, et al. WHO-EORTC classification for cutaneous lymphomas. Blood, 15 May 2005. Volume 105, Number 10.

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.

20061125 CS Lymph Nodes: Are positive right superficial inguinal lymph nodes coded to 30 (which is the case for anal canal primaries) or 31 (which is the case for anus primaries) if the primary is stated to be in the "cloacogenic zone" or is an anorectal 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.Assign code 30 for positive unilateral superficial inguinal lymph nodes for cloacogenic primaries. The cloacogenic zone is part of the anal canal.

Reportability: Is a tumor reported as "neoplasm" or "neoplasia" per the pathology report, which is subsequently clinically referred to as "carcinoma" reportable? See Discussion.

Example 1: Lung-Wedge resection and subsequent left lower lobe lobectomy showed papillary epithelial neoplasia. Tumor board and subsequent reports state "nonsmall cell carcinoma of lung."

Example 2: Kidney-Partial nephrectomy showed epithelial neoplasm, clear cells with low grade cytology. Subsequent urology clinic notes state that path revealed clear cell renal carcinoma.

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." Do we also accession the case if primary site has been resected? Would diagnostic confirmation be coded 8 (clinical diagnosis only)?

Accession the case and code Diagnostic Confirmation as 8 [clinical diagnosis only]. Accession a case with negative pathology when the clinician is aware of the negative pathology and continues to refer to the case as malignant.

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
