Significance of oncocytic features in poorly differentiated thyroid carcinoma - a bi-institutional experience.

ABSTRACT: Poorly differentiated thyroid carcinoma (PDTC), defined by Turin criteria, comprises a subset of high-grade follicular-derived thyroid carcinomas with intermediate prognosis. While differentiated oncocytic thyroid carcinomas demonstrate clinicopathologic and genetic differences compared to their non-oncocytic counterparts, similar data is limited in oncocytic (Hurthle) PDTCs (OPDTCs). Here, we assessed the impact of various oncocytic cut-offs in PDTCs on clinical, histologic and survival parameters.Our bi-institutional cohort comprised 210 primary PDTCs with available slides reviewed by at least one pathologist. Histologic features, including oncocytic fraction, were recorded. Clinicopathologic data were obtained, including overall survival (OS), disease-free survival (DFS), disease-specif
