RESUMEN
La positividad al HER2 se plantea como un factor pronóstico negativo en Cáncer Gástrico (CG), correlacionando con pobres tasas de sobrevida. Los reportes de tasas de positividad al HER2 en CG varían ampliamente (6-35%). El objetivo del estudio fue determinar la tasa de positividad y describir las características clínicas y patológicas de los CG Her2(+). Los tumores CG fueron centralmente screneados para inmunohistoquímica y FISH. 9% de loscasos fueron positivos, encontrándose mayor positividad en los estadios avanzados (III/ IV) vs. los estadios tempranos (I/II)(p= 0.045); en el tipo histológico intestinal vs. mixto/ difuso ( p=0.03 ) y en los cánceres de la unión gastroesofágica vs CG ( p=0.005).
ABSTRACT
HER2 positivity is thought to be a negative prognostic factor in gastric cancer (GC), correlating with poor survival rates. Reported HER2-positivity rates in GC have varied widely (6-35%).Objetive of this study is to determine rate of positivity and describe clinical and pathological characteristics of HER-2(+) GC. 100 GC tumour samples were centrallyscreened by immunohistochemistry and FISH. 9% of cases were positive . More positivity HER2 was found in advanced stages (III/IV) vs. early stages (I/II)(p=0.045) ; intestinal histology subtype vs diffuse/ mixed (p=0.045) and gastro-oesophageal junction cancervs GC ( p=0.005).
