The patient was never treated for the 2016 diagnosis, so the 2019 diagnosis is the same tumor that has progressed. Prior SINQ 20091096 for a similar case type cited multiple primaries per the 2007 Multiple Primaries/Histology Rules, Rule M8, the same rule as the current Solid Tumor rule M17, because this is to be reported as an incidence case.

However, it seems like Solid Tumor Rule M3 would apply because a single tumor is a single primary, and behavior of the 2016 primary would then be updated from /2 to /3. It is unclear how one would advance to the Multiple Tumors module and apply M17 because there is really only a single tumor in this case.

Patient had a thymectomy including pericardial fat for a mediastinal mass found incidentally during lung screening. Final diagnosis is WHO B3 thymoma. Staging Summary lists transcapsular invasion: "Present, as separate tumor nodules within peri-thymic adipose tissue." Tumor extension is stated to be "Confined to thymus, including peri-thymic adipose tissue." The pathologist staged this resection as pT1a pNX with no mention of mets. Clinically, there are no noted metastatic sites and no further treatment is planned.

SINQ 20180050 and 20130041 appear to have conflicting answers regarding the reportability of MBL with CLL (immuno)phenotype.

While the question content of SINQ 20180050 does not reference the CLL phenotype, it is included in the Discussion as part of the oncologist's assessment. The answer does not address the clinical diagnosis of MBL with CLL-phenotype and simply states that monoclonal B-cell lymphocytosis is not reportable.

SINQ 20130041 does include the CLL phenotype information in the primary question and it is expanded on in the discussion as present in peripheral blood. Based on that information, the answer is that it should be reportable and coded as CLL (9823/3).

The 2018 ICD-O-3 Histology Updates table lists serous tubal intraepithelial carcinoma (C57.0) with a behavior code of 2.

The EOD Primary Tumor schema for Fallopian Tube shows STIC has an extension code of 100. It also maps code 100 to Summary Stage 2018 L (localized).

Summary Stage 2018 for fallopian tube only documents that intraepithelial tumors are summary stage 0 (in situ).

There is one tumor in the left lung that is acinar adenocarcinoma, 8551/3, and two tumors in the right lung, one of which is 8551/3 and a separate one that is mucinous adenocarcinoma 8253/3.

3/21/18- left robotic video assisted thoracoscopy with left lower lobe lobectomy: 2.5 cm adenocarcinoma, acinar predominant, margins negative

11/3/18- right upper lobe lobectomy: invasive mucinous adenocarcinoma, 1.7 cm, invasive adenocarcinoma, acinar predominant, 0.6 cm, margins negative

If you start by comparing the 8551/3 left lung tumor to the 8253/3 right lung tumor, M6 applies and these would be separate primaries (seq 01 and seq 02). How would we handle the third tumor, 8551/3, in the right lung? Seq 01: 3/21/18- left lung primary 8551/3 Seq 02: 11/3/18- right lung primary 8253/3 Is the right lung tumor 8551/3 a third primary, and if so, which M rule applies? I cannot find a rule that seems to fit completely. Rule M6 may apply if you were comparing the right 8551/3 tumor to the seq 02 8253/3 tumor. But how would you know to use the seq 02 histology code 8253/3 or seq 01 histology code 8551/3 for the comparison? I think M9 was designed for situations where you have multiple tumors involving both lungs but they didn't biopsy all of them. Is that correct? If so, then we would be able to bypass M9. Would M11 apply since we already took care of two of the tumors with rule M6? If M11 doesn't apply, it seems like you would get to M14.

Washington State added to birth certificates, which allows people to have their certificates changed to this non-binary gender designation. Gender X is defined as a gender that is not exclusively male or female, including, but not limited to: intersex, agender, amalgagender, androgynous, bigender, demigender, female-to-male, genderfluid, genderqueer, male-to-female, neutrois, nonbinary, pangender, third sex, transgender, transsexual, Two Spirit, and unspecified.

In the April 2019 Breast Solid Tumor Rules update, the Priority Order for Using Documentation to Identify Histology was changed, giving equal priority to the Final diagnosis / synoptic report as required by CAP (item 2B).

There are technically two histologies documented for the case above; a Not Otherwise Stated (NOS)/No Special Type (NST) (invasive mammary carcinoma, per final diagnosis text) and subtype/variant (invasive cribriform carcinoma, per CAP report). If we do not use the synoptic report with priority over the final diagnosis, Rule H14 indicates the histology would be the NOS histology (invasive mammary carcinoma) because the percentage of tumor is not given for the subtype. However, SINQ 20180045 states, In the CAP protocol, the term Histologic Type is a label where the histology that corresponds to the largest carcinoma is collected. According to the CAP protocol for invasive breast cancer, the histologic type corresponds to the largest carcinoma.

If the pathologist summarizes the findings in a synoptic report, should the specific Histologic Type identified have priority?

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?
