20100032 First course treatment--Prostate: Is Degarelix coded as hormonal treatment for prostate cancer? Code the administration of Degarelix in the "Hormone Therapy" field. Assign code 01 [Hormone therapy administered as first course therapy]. This drug will be added to the next update of SEER*Rx. 2010
20100031

First course treatment--Anus: Is the topical application of trichloroacetic acid to an anal condyloma with AIN III first course treatment coded to 10 [Local tumor destruction, NOS] in the Surgery of Primary Site field?

Code the trichloroacetic acid treatment of reportable AIN III in the "Other Therapy" field. Assign code 1 [Other].

20100029 MP/H Rules/Histology--Corpus uteri: How should histology be coded and how many primaries should be accessioned for an endometrial primary in which curettings showed malignant mixed mullerian tumor (carcinosarcoma) but hysterectomy specimen showed endometrioid adencarcinoma? See Discussion. The pathology report COMMENT for the hysterectomy specimen stated that the previous curettage was reviewed. The findings are compatible with malignant mixed mullerian tumor. No residual features of malignant mixed mullerian tumor are found in the current resection, which shows FIGO grade I adenocarcinoma in the wall of the uterus. The malignant mixed Mullerian tumor appears to have been removed with the curettage. There is no information available regarding the number of tumors in these specimens.

For cases diagnosed 2007 or later, abstract a single primary. Rule M1 applies because there is no information on the number of tumors and there is no way to know whether the curettage sample was from a separate tumor or from the tumor in the hysterectomy specimen.

Apply rule H17 and code histology to 8980/3 for malignant mixed Mullerian tumor [Carcinosarcoma, NOS].

Primary site/Histology--Head & Neck: How are these fields coded when the final diagnosis for a skull based mass is "neuroendocrine carcinoma" and the IHC studies are incompatible with a brain/spinal cord primary (ependymoma)? See Discussion.

The pathology report final diagnosis is, "skull base mass, biopsy: neuroendocrine carcinoma, see note. NOTE: Ancillary IHC studies reveal ...the IHC signature is incompatible with ependymoma. The constellation of findings is diagnostic of well differentiated neuroendocrine carcinoma."

The site/histology combination of C410 and 8246/3 is 'impossible' by SEER edits. There is no override. What is the correct primary site and histology?

According to our subject matter expert physician, this unusual case is most likely a sino-nasal tumor (some variant of esthesioneuroblastoma [olfactory neuroblastoma]). Code to nasal cavity [C300] as indicated in ICD-O-3 by site-associated topography code attached to the morphology code for olfactory neuroblastoma [9522/3].

20100027 Reportability: Is AIN III reportable if it arises in the perianal skin? See Discussion. Physical exam states patient has a suspicious area of anal skin. Operative findings show a raised, suspicious lesion in the right perianal region. Our interpretation of the primary site would be skin and therefore not reportable. However, the final diagnosis on the pathology report indicates "AIN III/squamous cell carcinoma with focal areas suspicious for microinvasion. "SINQ #20041056 states that AIN III is reportable. AIN III of the anus or anal canal (C210-C211) is reportable. AIN III (8077) arising in perianal skin (C445) is not reportable. 2010
20100026 Multiplicity Counter--Kidney, Renal Pelvis: How many times is this field updated after an invasive primary is originally diagnosed? Should subsequently diagnosed in situ tumors to be included in this field? See Discussion. How should the Multiplicity Counter be coded when a patient has a renal pelvis primary [C659] diagnosed 1/23/08. The patient had one tumor, invasive grade 3 of 3 papillary urothelial carcinoma arising in the depth of a calyx in mid portion of kidney. In 6/1/09, a TURBT showed three separate high grade urothelial carcinoma in-situ lesions on the right side of the bladder, the largest tumor being 7mm. In 2/8/10, another TURBT showed one lesion on the left side of bladder, high grade urothelial carcinoma in-situ, tumor was 4mm. These are all a single primary per rule M8.

Code multiplicity counter 04. Count both invasive and in situ tumors.

Multiplicity counter would have been coded 01 in 2008. Add the three in situ tumors diagnosed in 2009 to the first tumor and update multiplicity counter to 04. Make only one update to multiplicity counter. Because the multiplicity counter was updated once, the fifth tumor diagnosed in 2010 does not need to be added.

MP/H Rules/Primary site--Kidney, Renal Pelvis: Should the primary site be changed to C689 [Urinary system, NOS] for a primary renal pelvis tumor after additional tumors are found months later in different urinary sites (e.g., bladder or ureter) and the MP/H Rules indicate these are all the same primary? See Discussion.

In a patient is diagnosed 1/29/08 with an invasive grade 3 of 3 papillary urothelial cell carcinoma arising in the depth of a calyx in mid portion of kidney, the primary site was coded C659 [Renal pelvis]. In 6/1/09 a TURBT showed three separate lesions on the right side of the bladder. The final diagnosis was high grade urothelial carcinoma in-situ with three tumors, the largest being 7mm. Per rule M8, the renal pelvis primary and subsequent bladder tumors are the same primary. Would the primary site be changed to C689 [Urinary system, NOS] when the bladder tumors were identified? Or is C689 only coded if more than one primary site is involved at diagnosis?

For cases diagnosed 2007 or later, Rule M8 applies. This is a single primary. The primary site was coded to C659 in 2008. Do not change the primary site code.

Histology: How is this field coded for a perivascular epithelioid cell neoplasm (PEComa) of uncertain malignant potential that is malignant based on the presence of metastases? See Discussion.

In 11/2006 the patient had surgery for a 6cm mass in the RUQ arising in the falciform ligament. The pathologic final diagnosis was: Perivascular epithelioid cell neoplasm (PEComa) of uncertain malignant potential. In 10/2009 a liver biopsy showed metastatic perivascular epithelioid cell neoplasm.

Assign histology code 8005/3 [malignant clear cell tumor]. According to our expert pathology consultant, this is the best histology code available at this time for the occasional tumor which is designated as malignant. The appearance of metastatic disease clearly defines this case as malignant.

20100022 Multiple primaries/Histology--Heme & Lymphoid Neoplasms: Is a 2010 diagnosis of ALK+ anaplastic T cell lymphoma following a 2008 diagnosis of follicular B cell lymphoma, grade 1 a new primary? If so, how is the histology coded? See Discussion. A patient has a history of Stage 4 follicular B cell lymphoma, grade 1 [9695/3] diagnosed in 2008. The patient was treated with Adriamycin, Cytoxan, Rituxan, and Prednisone. In 2010, the medical oncologist states the patient has progression/recurrence of lymphoma with pathology that has changed to anaplastic T cell lymphoma ALK+. There was immunophenotyping, but there was no more specific diagnosis made. The patient died within 3 months.

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

Abstract the anaplastic T cell lymphoma as a new primary. Code the histology to 9714/3 [Anaplastic large cell lymphoma, ALK-positive].

Rule M15 applies to this cases which instructs you to use the Multiple Primaries Calculator. The result for 9695/3 and 9714/3 is "New Primary."

Apply Rule PH30 to code histology which instructs you to use the Heme DB to determine the histology when rules PH1-PH29 do not apply. In searching the Heme DB for "anaplastic" the first term returned is Anaplastic large cell lymphoma, ALK-positive [9714/3].

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.

20100020 Histology/Behavior--Brain and CNS: How are these fields coded for a "cystic glioma"? Code the histology 9380/3 [Malignant glioma; Glioma, NOS]. There is no specific code for cystic glioma. 2010
