Pathology report: Left lower lobe lung, Tumor Size: Greatest dimension: 3.0 cm Additional dimensions: 2.5 x 2.0 cm; Tumor Focality: Unifocal; Histologic Type: Invasive adenocarcinoma Solid predominant with mucin production; Histologic Grade: G3: Poorly differentiated. Is the correct histology for this case 8230/3 (rule H5) or 8255/3 (rule H6)?

Examples:

Bladder TURB:  Invasive high grade urothelial carcinoma with poorly differentiated (40%), lipoid (5%), and sarcomatoid (55%) components.

Bladder tumor base TURB:  Invasive high grade urothelial carcinoma with poorly differentiated (65%) and sarcomatoid (30%) components.

The Urinary Sites Solid Tumor Rules, histology coding rules, say to code the most specific histology or subtype/variant, regardless of whether it is described as majority, minority, or component.  Poorly differentiated (8020) and sarcomatoid (8122) are both urothelial subtypes, but there is no rule to instruct how to code a tumor/tumors with multiple urothelial subtypes.

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.

There is an ICD-O histology code for follicular carcinoma, minimally invasive (8335/3) as well as follicular carcinoma, oxyphilic cell (8290/3). Per SINQ 20150045, the term oncocytic is synonymous with oxyphilic in this context.

The Multiple Primaries/Histology General Instructions and histology rules do not include the term “variant” as a term that can be used to code a further histologic subtype. The term “variant” can be used for the Other Sites (non-updated STR sites) when the ICD-O-3.2 (or ICD-O-3 for older cases) provides the term “variant” in the histology name.

The Extent of Disease (EOD) Manual states: Neoadjuvant (preoperative) therapy: If the patient receives neoadjuvant (preoperative) systemic therapy (chemotherapy, immunotherapy) or radiation therapy, code the clinical information if that is the farthest extension documented. If the post-neoadjuvant surgery shows more extensive disease, code the extension based on the post-neoadjuvant information.

1. (2017) Pituitary mass resection with a path diagnosis of

Do we code as prolactinoma when the tumor is immunoreactive for prolactin or must there be a definitive statement of ?

2. (2017) Pituitary lesion on imaging, MD diagnosis of

Current (2007) MP/H rule H9 states when there are multiple histologies in the same branch in Chart 1, code the more specific histology. These histologies are NOT in Chart 1, but prolactinoma seems to be a more specific type of pituitary adenoma. The next rule, H10 states to code the numerically higher code, 8272/0 (pituitary adenoma)?

3. (2017) Imaging diagnosis of pituitary macroadenoma with clinical diagnosis by MD of macroprolactinoma.

Current rules indicate when there is no path specimen that physician reference to type of tumor has priority over imaging.

Will these answers/histologies change with the upcoming 2018 Solid Tumor rules?

In the Hematopoetic Manual, page 22, it is states: "The use of donor leukocyte infusions for treatment of hematopoietic neoplasms, specifically leukemias, is increasing.  Abstract as bone marrow transplant when a reportable hematopoietic neoplasm is treated with donor leukocyte infusion, even if it is not listed in the treatment section of the Heme db for the specific neoplasm."  Question 20110048 in the SEER Inquiry, it is stated "Donor lymphocyte infusion (DLI) is coded as immunotherapy."  Donor lymphocyte infusion and donor leukocyte infusions are the same procedure.  Please clarify discrepancy as coding is needed for a case treated with donor lymphocytic infusion.
