Explican que dicho patrón se basa en la metilación del ADN, proceso que utilizan las células sanas para desactivar ciertos genes, pero que está fuera de control en las células tumorales. Descubrieron que los cánceres con células tumorales que contienen niveles bajos de metilización del ADN presentan menos probabilidades de recurrir que aquellos con niveles altos de metilización.
A su juicio, detectar estos niveles puede servir para determinar el riesgo de recidiva del cáncer entre las afectadas.
Su estudio se llevó a cabo con 215 pacientes con cáncer de endometrio, 39 de ellas de raza negra.
