“…In this study, in accordance with the literature data, we observed PCNA positive reactions in the brown color in the nucleus of tumor cells (13,24). In addition, similar to previous studies, we detected PCNA expressions in the cytoplasm of cells undergoing mitosis (19,22,23,25). Similar to the study conducted by Ilhan et al 2008 (24), we did not detect any PCNA positive reaction in normal mammary glands.…”

“…Preziosi et al 1995 (19), Peña et al 1998 (22), Zacchetti et al 2003 (23) and Silva et al 2016 (25) demonstrated PCNA immunoreactivity both intensely and weakly in the nucleus, they also found a positive reaction in the cytoplasm of cells that undergoing mitosis. In addition, Silva et al 2016 (25) found that PCNA immunostaining reacted more intensely in the nuclei of tumoral cells in the mammary glands compared to connective tissue and myoepithelial cells. They did not find any PCNA expression in bone and cartilage-derived myxoid areas (25).…”

“…Além disso, a análise de marcação de receptores de estrógeno e progesterona e de HER-2 em dois discos de 0,6 mm é comparável à análise de todo o tecido neoplásico em 95% dos casos (Camp et al, 2000;Glajcar et al, 2013). Outro trabalho avaliou a marcação de PCNA, vimentina e citoqueratinas em tumores mistos, os quais possuem grande heterogeneidade tecidual, evidenciando resultados de compatibilidade entre as análises de um fragmento de 1 mm e da amostra tumoral inteira (Silva et al, 2016).

“…A análise imuno-histoquímica utilizou a técnica de Tissue Microarray que, embora não permita a análise integral do tecido tumoral, possui o benefício de reduzir os custos e tempo das análises. Vários trabalhos validam esta técnica para marcadores de imuno-histoquímica (Camp et al, 2000;Glajcar et al, 2013;Choi et al, 2005;Silva et al, 2016). Na Medicina, a técnica já é utilizada na rotina, possibilitando que um número maior de pacientes se beneficiem do valor prognóstico e preditivo das análises imunohistoquímicas.…”
