MP/H Rules/Multiple primaries--Bladder: Which multiple primary rule is used to determine the number of primaries to accession when a patient has a papillary transitional cell carcinoma of the bladder diagnosed in 2009 followed by a high grade invasive urothelial carcinoma with neuroendocrine features per immunohistochemistry diagnosed in 2010? See Discussion.
SEER*RSA/Required data items--Melanoma: The site-specific data item, Ulceration, states it is required by "All" in SEER*RSA but in the NAACCR Data Dictionary table it states is it required by SEER, Commission on Cancer (CoC), and Canadian Cancer Registry (CCCR), not the National Program of Cancer Registries (NPCR). Does the definition of "All" in SEER*RSA not include NPCR? Also, please explain the difference between Required by: "All" and "Required by CCCR/Canada, COC, NPCR, SEER" (all listed out).
Primary site--Colon: How do you determine the correct subsite when there is conflicting information in different reports? Are there priority rules for coding subsite for sites other than Head and Neck? See Discussion.
Residence at dx: After living elsewhere (Florida) and traveling around the country in an RV with his spouse, is a patient a resident of this area for either primary if he was diagnosed with his first primary less than a month after arriving in the area and a second primary more than a year after parking his RV here?
Grade--Head & Neck: How should grade be coded for a tonsillar primary (or other solid tumor) with resection pathology final diagnosis of poorly differentiated SCC with histologic grade: G2-3 of 3. See discussion.
Primary site--Brain and CNS: How is the primary site to be coded if a clinician used an MRI to diagnose a left cerebellar venous angioma? See Discussion.
Reportability--Vulva: Is this reportable? We have begun to see the following diagnosis on biopsies of the vulva with the statement below. The diagnosis is being given as simply VULVAR INTRAEPITHELIAL NEOPLASIA, no grade is noted. See discussion.
Update to current manual/EOD 2018/Summary Stage 2018--Fallopian Tube: How are behavior, EOD Primary Tumor, and Summary Stage 2018 coded for a diagnosis of serous tubal intraepithelial carcinoma (STIC) of the fallopian tube? See Discussion.
Update to current manual/Lymphovascular invasion: Are lymphvascular invasion and lymphvascular space invasion on a pathology report the same thing or do they describe different things?
