SINQ 20160008 discusses the reportabilty and diagnosis date for liver primaries where imaging references the LI-RADS category as LR-5 or LR-5V. The 2018 SEER Coding and Staging Manual, Appendix E Reportable Example #16, demonstrates this concept. According to the LI-RADS categories a value of 5 is "definitely HCC" and is concordant with OPTN 5. Often we see only the OPTN categorization.

A. Sentinel lymph node, left: One lymph node, negative for metastatic tumor on three levels of routine H\T\E and pan cytokeratin immunohistochemical stains.

B. Left breast: Procedure: Total mastectomy with skin and nipple. Specimen Laterality: Left. Lymph Node Sampling: Yes, portion A. Specimen Integrity: Intact. Histologic Type: Extensive ductal carcinoma in situ and one focus of Invasive ductal carcinoma with mucinous features. Histologic Grade (Nottingham Histologic Score): Glandular Differentiation: Score 3 Nuclear Grade: Score 2. Mitotic Count: Score 1. Total Nottingham score 6 (grade 2, moderately differentiated). Tumor Size: 3.3 x 2 mm (0.33 x 0.2 cm) measured on slide (B3). Tumor Site: Lower inner quadrant of left breast. Tumor Focality: Unifocal. Ductal Carcinoma In Situ (DCIS): Present, cribriform, solid and micropapillary types with focal necrosis and calcifications. Size of DCIS: Number of blocks examined: Thirty (30). Number of blocks with DCIS: Thirteen (13). Lobular Carcinoma In Situ (LCIS): Not identified, Lymphovascular Invasion: Present. Perineural Invasion: Not identified. Other Findings: Changes consistent with previous biopsy site. Cysts, foci of atypical ductal hyperplasia, focal ductal hyperplasia, adenosis, stromal fibrosis and microcalcifications. Skin (epidermis): Uninvolved. Nipple: Uninvolved. Margins: 1 mm from DCIS to the closest deep margin (slide B12). At least 10 mm (1 cm) from invasive carcinoma to deep margin. Estrogen receptor (ER, clone 1D5) by immunohistochemistry performed on this material: Positive (invasive and in situ carcinoma), high intensity, in greater than 95% of carcinoma cells. Progesterone receptor (PR, clone 16) by immunohistochemistry performed on this material: Positive (invasive and in situ carcinoma), moderate intensity in about 80% of the carcinoma cells. Her 2 by FISH performed on this material: Pending, an addendum to follow. Pathologic staging: pT1aN0(sn)MX (AJCC 7th edition). Dictated by: (Pathologist), MD Intradepartmental review.

Patient has a history of breast cancer and diffuse large B-cell lymphoma (DLBCL), both treated with chemotherapy and radiation.

On 6/26/19, bone marrow biopsy: MDS with excess blasts-2 (18% dysplastic blasts) in a normocellular marrow (overall 40% cellularity) with trilineage dysplasia. Comment: least myelodysplastic syndrome with excess blasts-2. However, an early/evolving AML cannot be completely excluded. The findings likely represent therapy-related myeloid neoplasm.

MD note on 7/15/19: Diagnosis: MDS, high grade borderline AML with complex karyotype secondary disease. Patient has high grade MDS which is bordering on AML transformation with 20% blasts by IHC and areas higher than this. This is likely secondary to the treatment she has received for her other cancers particularly pelvic radiation for her DLBCL. Given her very high IPSS score, it is likely she will eventually develop AML. No treatment given.

On 7/15/19, bone marrow biopsy: Persistent acute leukemia in a marrow with trilineage dyspoiesis and 23% blasts.

Example: Brain MRI shows a mass along underside of right tentorium extending to posterior incisura consistent with meningioma. Spinal MRI shows mass at C4-5 level consistent with meningioma. Resection of spinal meningioma shows final diagnosis of meningioma and College of American Pathologists (CAP) protocol summary indicates Histologic Type (WHO classification of tumors of the central nervous system): Meningioma, meningothelial. There is no resection of the cerebral meningioma planned. Is the CAP protocol used if it provides a further subtype for meningiomas? Per Solid Tumor Rules, the final diagnosis has priority over the CAP summary. The answer to this question does affect the number of primaries accessioned in this case.

There is a discrepancy between Notes 3 and 6 in the schemas Fallopian Tube, Ovary, and Primary Peritoneal Carcinoma for EOD Primary Tumor. Note 3 describes extension/discontinuous metastasis to the pelvic sites (code 450) and includes the sigmoid colon, rectosigmoid and rectum since these are all pelvic sites. However, Note 6 also includes rectosigmoid and sigmoid colon.

Note 6 is describing extension/discontinuous metastasis to the abdominal sites (600-750), so it should include rectosigmoid or sigmoid colon (since those are pelvic sites). Note 6 indicates, Intestine, large (except rectum). In the previous Collaborative Stage, the corresponding note used to also include: except sigmoid colon, rectosigmoid and rectum.

Did sigmoid colon and rectosigmoid get removed from the list here? That is, should Note 6 read, Intestine, large (except sigmoid colon, rectosigmoid, rectum)? Involvement of the sigmoid, rectosigmoid, or rectum via peritoneal seeding/metastasis is consistent with T2b disease and would correlate with code 450 (pelvic sites), not codes 600-750 (abdominal sites). Those codes only correlate with T3 and greater disease (i.e., peritoneal seeding/metastasis of the abdomen).

Pathology Diagnosis: Left temporal lesion - Low grade glial/glioneuronal neoplasm BRAF mutant. Pathologist Comment: The histopathological appearance of this lesion does not allow for a definitive diagnosis. However, the low-grade appearance, fibrillary nature, immunohistochemical profile, and the presence of a BRAF V600E mutation allow this to be categorized as a low-grade glial or possibly glioneuronal tumor. Despite the lack of exact classification this neoplasm can be expected to behave in a very indolent manner consistent with a WHO grade I classification.

In addition to the issue mentioned above, there is a SINQ answer that conflicts with the 2018 ICD-O-3 Histology Update table. SINQ 20130134 indicates indolent systemic mastocytosis is reportable for cases diagnosed 2010 and forward. There is no date restriction indicating the SINQ note applies only for cases diagnosed 2010-2017. Since indolent systemic mastocytosis was changed to borderline (9741/1) for diagnosis year 2018+, should the diagnosis year range be updated for this SINQ answer?

We previously downloaded the 8/22/2018 ICD-O-3 histology update tables which included the note, not reportable for 2018, for both of these terms (with an updated histology 8071/2). SINQ 20180020 confirms differentiated penile and vulvar intraepithelial neoplasia are NOT reportable for 2018 (as does 20160069). However, when looking at the 8/22/2018 ICD-O-3 histology update table today, the not reportable for 2018 comment has been removed and it appears these two terms are reportable. Which is correct?

It appears that the first Other Sites applicable rule is H16 (and Table 2) instructing the use of histology code 8323 (mixed cell adenocarcinoma). However, this really is not an adenocarcinoma tumor but is a mixed squamous and transitional cell carcinoma. The 2018 ICD-O-3 Histology Update Table provides a new term for a but does not indicate whether that new term would also include a papillary squamotransitional cell carcinoma of the cervix.

Patient is diagnosed with invasive ductal carcinoma (IDC), right breast, receives HT, radiation therapy, and surgery. The same patient is diagnosed with LCIS, left breast one month later--recommend surveillance only (no surgery). Is the HT for the left breast coded at all? I think for COC/NCCN, we do not, but for SEER what would I do? Treatment in the SEER Manual 2018 states, "Code the treatment on each abstract when a patient has multiple primaries and the treatment given for one primary also affects/treats another primary." The example include bladder/prostate and ovarian/cervix. It also states, "Code the treatments only for the site that is affected when a patient has multiple primaries and the treatment affects only one of the primaries." The example includes colon/tonsil. Breast LCIS treatment appears complicated. Per NCCN guidelines, this condition no longer has recommendations, however it appears as though they still state that if a core biopsy is done and is LCIS, follow up should be ultrasound or surgical excision. Nowhere does it state hormone is recommended.
