ABSTRACT

El objetivo de este estudio fue determinar la presencia del Virus Papiloma Humano (VPH) tipo 16 y 18 en biopsias de tejido mamario parafinado de pacientes con diagnóstico clínico de cáncer de mama. Se analizaron 32 biopsias de cáncer de mama embebidas en parafina para detectar el ADN de VPH mediante PCR en tiempo real, los iniciadores estuvieron dirigidos al gen E6. Se evaluaron el tipo histológico, grado histológico y la sobreexpresión de C-erB2 y Ki-67 mediante inmunohistoquímica. El 84,38% (27) fueron positivos para VPH, el 25% (8) fueron positivos para VPH-16 y el 59,38% (19) para VPH-18. El 15,63% (5) de las muestras presentaron infección mixta. Se evidenció la sobrexpresión de C-erbB2 y Ki-67 en 6,25% (2) de las muestras positivas para VPH-16 y 15,63% (5) de las muestras positivas para VPH-18. Se detectó ADN de VPH-16 y VPH-18 en las muestras de biopsias analizadas mediante PCR en tiempo real.


The aim of this study was to determine the presence of Human Papillomavirus (HPV) type 16 and 18 in biopsies of paraffin-embedded breast tissue from patients with clinically diagnosed breast cancer. 32 paraffin-embedded breast cancer biopsies were analyzed in order to detect HPV DNA by real-time PCR, the primers were directed at the E6 gene. The histological type, histological grade and overexpression of C-erB2 and Ki-67 were evaluated by immunohistochemistry. 84.38% (27) of the samples were positive for HPV, 25% (8) were positive for HPV-16 and 59.38% (19) were positive for HPV-18. Mixed infection was found in 15.63% (5) of the samples. Overexpression of C-erbB2 and Ki-67 was seen in 6.25% (2) of the samples positive for HPV-16 and in 15.63% (5) samples positive for HPV-18. HPV-16 and HPV-18 DNA was detected in the biopsy samples analyzed by real-time PCR.
