Reportability--Colon: Is a polypectomy that is suspicious for invasive adenocarcinoma followed by a partial colectomy with no residual neoplasm reportable? See Discussion.

08/28/2009 Cecum biopsy showed an adenomatous polyp with focal areas suspicious for invasive adenocarcinoma.

SINQ 20071060 states a suspicious biopsy that is disproven by a subsequent surgical procedure is not reportable. That does not seem to apply in this case because the patient had a suspicious finding on a surgical procedure (polypectomy), followed by a second surgical procedure that was negative. Is it possible that the polypectomy removed the entire tumor and the suspicious diagnosis should be reported?

This case is reportable.

It is possible that the polypectomy removed the entire tumor. Invasive carcinoma in a polyp does not mean that is has invaded the stalk of the polyp. If the stalk is not invaded, all of the cancer may have been removed by a polypectomy.

20110005 Histology--Heme & Lymphoid Neoplasms: How is the pre-2010 histology coded for a "follicular grade 2, non-Hodgkin lymphoma with marginal zone B-cell differentiation"? See Discussion. This patient was seen in 2010 for the same primary as diagnosed in 2006. The histology was coded to marginal zone lymphoma [9699/3] in 2006. Is this correct? Or should this have been coded as a follicular lymphoma, ignoring the modifying expression "marginal zone B-cell differentiation"?

This is a 2006 diagnosis. The histology code is 9691/3 [follicular lymphoma, grade 2]. Do not code differentiation for hematopoietic cases.

For diagnoses 2010 and forward, a small number of cases of follicular lymphoma do have marginal zone differentiation. However, there is no code for this variant of follicular lymphoma. It would simply be coded as a follicular lymphoma because that is the most accurate histology code available. The marginal zone differentiation is not to be coded as a second primary (marginal zone lymphoma).

20110002 Surgery of Primary Site--Penis: How is CO2 laser treatment coded for penile cancer? Assign code 14 [laser] for CO2 laser treatment given for primary penile cancer. The CO2 is the method used to deliver the laser. 2011

Reportability--Melanoma: Is a pathology report with a final diagnosis stating only non-reportable terms, followed by a re-excision pathology report that indicates "no residual melanoma" reportable? See Discussion.

Is a case reportable if the final diagnosis on an initial pathology report states a non-reportable term (e.g., evolving melanoma, early/evolving melanoma or melanocytic nevus) and followed by a subsequent re-excision pathology report stating there is "No residual melanoma"? There is no mention in the clinical history on the subsequent pathology report that the diagnosis was thought to be melanoma following the first procedure. The first mention of the reportable term was in the final diagnosis of the subsequent pathology report that stated "no residual melanoma."

No. This case is not reportable based on the information provided. "No residual melanoma" is not diagnostic of a reportable neoplasm.

We recommend that you try to obtain more information from the clinician/pathologist for this case due to the poor documentation. Check for any additional resection performed.

20110106 Primary site--Heme & Lymphoid Neoplasms: How is the primary site to be coded for a 2010 diagnosis of follicular lymphoma involving the spleen and lymph nodes above and below the diaphragm?

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Use Rule PH21 to code the primary site to C778 [lymph nodes of multiple regions]. The spleen is not listed under the Primary Site(s) section in the Heme DB for follicular lymphoma. Per Rule PH21 code the primary site to multiple lymph node regions, NOS (C778) when multiple lymph node regions, as defined by ICD-O-3, are involved and it is not possible to identify the lymph node region where the lymphoma originated. The spleen is a primary site for only a few lymphomas (noted in the Heme DB). Because the spleen filters blood, it is often reactive (splenomegaly) or frankly involved with the lymphoma. That reaction or involvement, however, does not affect the primary site coding. Only the involved nodes are used in coding primary site.

SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms. Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx.

Primary Site--Brain and CNS: Are meninges surrounding cranial nerves cranial meninges [C700] or a part of the specific nerve's sheath? Is the primary site for an optic nerve sheath meningioma coded to optic nerve [C723] or cranial meninges [C700]?

Code the primary site to cranial meninges [C700].

20110090 MP/H Rules/Histology/Behavior--Ovary: How are these fields coded for a 20 cm borderline mucinous tumor with a 0.3 cm minor focus of intraepithelial carcinoma of the ovary that the pathologist stages as T1a?

According to the MP/H rules, code histology to 8010/2 [intraepithelial carcinoma] for cases diagnosed 2007-2014. Borderline mucinous tumor is not reportable to SEER.

The steps used to arrive at this decision are:

Go to the Other Sites Histo rules found in the Multiple Primary and Histology Coding Rules Manual.

Start at the SINGLE TUMOR: IN SITU ONLY module, rule H1. Code the histology when only one histologic type is identified. The only reportable histology in this case is intraepithelial carcinoma [8010/2].

20110091 MP/H Rules/Histology--Bladder: How is this field coded for a patient with ureter specimen with "high grade urothelial carcinoma with adenocarcinoma differentiation" and a TURB specimen with "urothelial ca, high grade, a biphasic pattern with cautery-distorted urothelial carcinoma and adenocarcinoma"?

According to the MP/H rules, code histology to 8120/3 [urothelial carcinoma] for cases diagnosed 2007 or later. The term "glandular differentiation" is equivalent to adenocarcinoma differentiation. 8120/3 [urothelial carcinoma] would be the best way to code a "biphasic pattern with cautery-distorted urothelial carcinoma and adenocarcinoma" according to a pathologist consultant.

The steps used to arrive at this decision are as follows:

Go to the Urinary Histo rules found in the Multiple Primary and Histology Coding Rules Manual.

Start at the MULTIPLE TUMORS ABSTRACTED AS A SINGLE PRIMARY module, rule H9. Code the histology to 8120 [transitional cell/urothelial carcinoma] when there is transitional cell carcinoma with glandular differentiation.

20110080 Grade--Kidney, renal pelvis: How is this field coded for a non-invasive high grade papillary urothelial carcinoma of the renal pelvis? See Discussion. Per instructions in the 2010 SEER Manual, Appendix C, Coding Guidelines for Bladder, "Code grade 9 (unknown) for non-invasive urothelial (transitional) tumors." The Coding Guidelines listed under Renal Pelvis, Ureter are only for Kidney [C649]. Do the grade instructions under bladder apply to ALL non-invasive urothelial tumors, or are we to use the kidney grading instructions to code grade for renal pelvis and ureter malignancies? Code grade to 4 [high grade]. Follow the instructions in the main part of the 2010 SEER Manual under the data item Grade (pages 73 - 76). There are no specific instructions for coding grade for renal pelvis. Apply the general instructions in the absence of site-specific instructions. 2011
20110079 MP/H Rules/Histology: In the MP/H Manual, where is the documentation indicating "focal" is not a term that can be used to code histology? See Discussion. Example: neuroendocrine carcinoma with focal squamous differentiation. For the purposes of the MP/H rules, the term "focal" is not used to indicate a more specific histology. Terms that may be used to indicate a more specific histology are listed in the relevant histology rules. For example, see Breast histology rule H3. Notice the terms listed in the note for this rule are "type, subtype, predominantly, with features of, major, with ___ differentiation, architecture or pattern." The term "focal" is not included. This concept will be clarified in future revisions to MP/H rules. 2011
