“…- (27) and Soares et al (28) showed that the percentage of Ki-67 and PCNA expression was higher in anaplastic and poorly differentiated/undifferentiated thyroid carcinomas, respectively. In our study, a high SPF showed a significant correlation with worse prognosis and a higher proliferative activity paralleling a higher aggressive clinical course ( Fig.…”

“…A expressão deste oncogene foi encontrada em tumores tireoidianos papilíferos em níveis não tão elevados como em outros tumores epiteliais mas duas a três vezes mais elevada que no tecido tireoidiano normal onde também é encontrado 27 . Nenhuma amplificação ou rearranjo desses genes, contudo tem sido observada 8, 10,17 . A positividade para o c-erbB2 foi maior nos tumores de grau histopatológico mais baixo que nos de grau mais elevado.…”

“…Mutações deste gene nos domínios dos exons 5 a 8 da molécula, modificam sua capacidade supressora e são encontradas em vários cânceres humanos. Nos tumores tireoidianos, o antioncogene p53 é prevalentemente encontrado no carcinoma anaplásico e também em alguns carcinomas pouco diferenciados 8, 10,13,16,35 . Diferentemente dos oncogenes ras e gsp, as mutações do p53 ocorrem em múltiplos sítios de suas regiões evolutivamente conservadas 9, 13,14 .…”

“…Aneuploidy per se has been proposed to be an early and genetically destabilizing force in cancer development (17), but the molecular mechanisms underlying aneuploidy are poorly understood. In thyroid lesions, aneuploidy is mostly found in poorly-differentiated thyroid carcinomas (PDTCs), is rare in papillary thyroid carcinomas (PTCs), being observed in a range of 10-57% of follicular tumours (18), and in 10-22% of nodular hyperplasias (NHs) (19)(20)(21).…”
