(aacrjournals.org)
For ovarian cancers, there are seven WAY-600 different studies, including those of Bonome, T. mRNA manifestation level is usually clearly increased in stage III high-grade papillary serous ovarian tumors in the study of Bonome, T. mRNA manifestation level is usually not elevated in numerous stages of ovarian serous cystadenocarcinoma in the TCGA data source, suggesting that reflection is certainly just elevated in high-grade carcinomas. (technologybooksindustrialprojectreports.com)
Although OPN expression was identified in a good number of bladder, prostate, and brain tumors, the majority of 6 skin cancers, 11 of 14 salivary gland cancers, 2 thyroid carcinomas, and 23 of 26 breast cancers revealed low OPN positivity or were negative. (aacrjournals.org)

Epithelial4
Papillary lesions of the breast represent a heterogeneous group of lesions including benign papillomas, papillomas with focal epithelial atypia, fully fledged ductal carcinoma in situ (DCIS) or lobular neoplasia, papillary DCIS, encapsulated papillary carcinomas without or with invasion, solid papillary carcinomas, and invasive papillary carcinomas.

(bvsalud.org)
Finally, a new class was defined called carcinoma with pleomorphic, sarcomatoid, or sarcomatous elements, which brings together a number of proliferations characterized by a spectrum of epithelial to mesenchymal differentiation. (ersjournals.com)
