Reportability--Heme & Lymphoid Neoplasms: Is this a reportable case and if so what codes would be used for the primary site and histology?

Lymph node flow cytometry and bone marrow biopsy revealed involvement by a low-grade B-cell lymphoproliferative disorder. Medical oncologist states monoclonal gammopathy, question marginal zone B cell lymphoma versus lymphoplasmacytic lymphoma/lymphoproliferative disorder.

Based on the information provided, this case is not reportable. Low grade B-cell lymphoproliferative disorder is not reportable, nor is monoclonal gammopathy. There is no definitive diagnosis for marginal zone or lymphoplasmacytic lymphoma. The terminology used includes "question" and "versus" which are not acceptable ambiguous terms for reportability. If possible, follow up with the physician regarding the definitive diagnosis.

Reportability--Testis: Is a mature teratoma of the testis reportable? See discussion.

Mature teratoma is listed as a benign neoplasm (9080/0) in the ICD-O-3. SINQ 20120085 references a NAACCR Webinar that indicated pure mature teratomas of the testis in adults are reportable. We are not aware of any further documentation of this change in reportability. When did mature teratomas of the testis for adults become reportable? What is the defined age range for "adult"? The original SINQ question above lists the 2012 SEER Manual as a Reference, however, no clarification or mention of this change in reportability was found in that manual.

For testis, mature teratoma in an adult (post-puberty) is reportable because it is malignant (9080/3); however, mature teratoma in a child is benign (9080/0). The 2011 NAACCR webinar introduced this concept and it was documented in the 2012 SINQ question. You may use 2011 or 2012 as the date of this change. The next edition of the SEER manual will include reportability examples.

20140016 MP/H Rules/Histology--Bladder: What is the correct histology code for this situation? See discussion. Patient has 2 bladder tumors, both invasive -- one is transitional cell carcinoma (8120/3) and the other is papillary TCC (8130/3). They have the same extent of disease, both involve the lamina propria. Is this 8120, because of the Note under rule H11 or is this 8130 because under rule H12, it says 'papillary carcinoma and transitional cell carcinoma'? If so, what is the meaning of the note under rule H11?

Rule H12 applies, code to 8130.

The note under H11 is intended to explain the order of the rules; that is, why the rule to code papillary transitional/urothelial cell carcinoma (H12) follows the rule to code transitional/urothelial cell carcinoma (H11).

Surgery of Primary Site--Brain and CNS: What procedure code would be used for NeuroBlate Laser Interstitial Thermal Therapy? This procedure was used for a Glioblastoma of the brain.

If a pathologic specimen is not taken during this procedure, code in the surgery field using code 10 (Local tumor destruction, NOS). If specimen is sent to pathology, code 90, surgery, NOS. We will request this procedure be included in future treatment field coding documentation.

Our research notes that this procedure, also known as LITT (Laser Interstitial Thermal Therapy), is a surgical treatment. Lasers transmit heat to coagulate or destroy the brain tumors from the inside out.

Reportability/Primary Site--Lip: Is a right lower lip (NOS) squamous cell carcinoma reportable when the microscopic description states the tumor arises from the epidermis and extends through the dermis? See discussion.

We are having difficulty determining whether the primary site is lip, NOS (C009) or skin of lip (C440). Usually we look for a statement of “skin” or “mucosa” in the microscopic description if the specimen label is only lip, NOS as instructed by the previous SINQ 20051049. Is a statement of "epidermis" or "dermis" in the microscopic description enough to indicate carcinoma is arising in the skin of the lip (C440) and thus not reportable?

This case is interpreted as skin of lip and not reportable. According to our expert pathologist consultant, the pathologist in this case "is specifically saying "epidermis" and "dermis" and I would have to think it is skin, and thus not reportable."

MP/H Rules/Histology--Bladder: What is the correct histology for the following bladder case and how do you determine? See discussion.

8/1/10 CYSTOSCOPY -- MULTIPLE BLADDER TUMORS INVOLVING POSTERIOR WALL, DOME & BLADDER NECK AREA. LARGEST WOULD BE MORE THAN 5 CM IN SIZE. 8/17/10 path -- BLADDER TUMORS:PAPILLARY TRANSITIONAL CELL CARCINOMA OF urinary bladder, GRADE III. ONE FRAGMENT OF TISSUE SHOWS NECROTIC CHANGE WITH APPARENT TRANSFORMATION TO A HIGH GRADE SARCOMATOID VARIANT W ITH EXTENSIVE SUBMUCOSAL INVASION & FOCAL AREA SUGGESTIVE OF ANGIOLYMPHATIC INVASION NOTED. MAJORITY OF TUMOR APPEARS CONFINED TO MUCOSAL SURFACE W ITH NO OTHER AREAS OF DEFINITIVE SUBMUCOSAL INVASION FOUND.

Code 8122/3 (UC/TCC, Sarcomatoid). Rule H5 and Table 1 apply.

This is based on the information provided: Transitional Cell Carcinoma with sarcomatoid variant, and Table 1 in Terms and Definitions for "Ureter/Renal Pelvis/Bladder".

MP/H Rules/Histology--Testis: How should histology be coded for a testicular teratoma with somatic type malignancy (adenocarcinoma)? See discussion.

11/8/2013 Rt orchiectomy: teratoma with somatic type malignancy (adenocarcinoma).

5/2/2014 Abdominal mass excision: metastatic teratoma involving matted lymph nodes. Patient age at diagnosis is 31.

Per web search, a teratoma with somatic type malignancy is a rare type of tumor. Should the histology be coded to 8140/3? This seems to conflict with SINQ 20120085, which indicates a testicular mature teratoma in an adult is malignant, and in this example, it was also the portion of tumor that metastasized.

Assign code 9084/3, listed in ICDO as teratoma with malignant transformation.

Our expert pathologist consultant states that this is a very rare situation. The non-germ cell components are believed to arise out of the teratoma portions, and are seen in only of few percent of teratomas. They are given the designation "teratoma with somatic type malignancies" (WHO).

20140001 Grade--Brain and CNS: How should grade be coded for a pineal parenchymal tumor of "intermediate differentiation"? See discussion.

Per a web search, the term "pineal parenchymal tumor of intermediate differentiation" refers to a pineal tumor with the histology/behavior that falls somewhere between the category of pineocytoma (9361/1) and pineoblastoma (9362/3). In other words, it is a malignant tumor that is a WHO grade II/III neoplasm because it's histologic features and behavior are not quite equivalent to a pineoblastoma (WHO grade IV). Thus, it appears the expression "intermediate differentiation" is actually referring to a type of WHO classification system rather than the grade field.

Should the type of documentation provided in pathology report be used to imply the grade field is being referenced and thus be coded to 2 for "intermediate differentiation" or should grade be coded to 9 based on the information found during the web search?

Code the grade as 2 based on instruction #8 in the revised grade instructions for 2014.

Do not use WHO grade to code the grade field for CNS tumors.

20140010 Multiple primaries--Heme & Lymphoid Neoplasms: Is this one primary or two? Follicular lymphoma grade 1 (9695/3) on 8/23/12 from an abdominal lymph node. On 1/6/14 an abdominal lymph node biopsy showed diffuse large b cell lymphoma arising from high grade follicle center cell lymphoma. Patient has been on observation.

1st primary, 8/23/12: Follicular lymphoma, grade 1 2nd primary, 1/6/14: Diffuse Large B Cell Lymphoma

Apply the multiple primary rules twice for this case. The 2012 diagnosis is follicular lymphoma. There are two histologies in 2014: diffuse large b cell lymphoma and follicle center cell lymphoma diagnosed at the same time in the same location. This is one primary per rule M4.

Then compare the 2012 diagnosis to the 2014 diagnosis.

Per the Hematopoietic Database, follicular lymphoma (all types) transforms to DLBCL. Per Rule M10, the DLBCL would be a second primary.

20140002 Reportability--Appendix: Is a pathologic final diagnosis of an appendix with "well-differentiated neuroendocrine tumor (carcinoid)" reportable? See discussion. SINQ 20130027 states that "well-differentiated neuroendocrine tumor" of the appendix is reportable (8240/3) while "carcinoid" tumors of the appendix are not reportable (8240/1). Please explain the difference between "well-differentiated neuroendocrine tumor" of the appendix and a "carcinoid" of the appendix.

Well-differentiated neuroendocrine tumor of the appendix is reportable. The difference is terminology. "Carcinoid" is listed in ICD-O-3 as a /1 for appendix making it non-reportable.

When both terms are used, ask for clarification from the pathologist. Failing that, accept the reportable terminology and report the case.
