ABSTRACT
Colorectal cancer (CRC) is the third most common cancer in the world. Fortunately, it is also proven to be one of the most preventable cancers, in large part due to the utilization of CRC screening. Historically, it was believed that the adenomatous polyp was the only precursor to carcinoma of the colorectum. Within the last decade, it has been shown that approximately 20-30% of sporadic colon cancers arise through a distinct molecular pathway called CpG Island Methylation (CIMP) which is due to widespread DNA methylation. There is strong evidence that serrated polyps are the precursor lesions for colon cancers arising through the CIMP pathway.
RESUMEN
Cáncer Colorectal (CRC) es el tercer cáncer más común en el mundo (1). Afortunadamente también se ha probado que es el cáncer que más se puede prevenir, en gran parte debido al "screening" del CRC. Históricamente, se creía que el pólipo adenomatoso era el único precursor del carcinoma de colon y recto. En la última década se ha demostrado que aproximadamente el 20 al 30% de los cánceres colónicos esporádicos se derivan de una vía molecular diferente llamada Metilación de las Islas CpG (CIMP) que es debida a una extensión de la metilación del DNA.Actualmente hay una fuerte evidencia que los pólipos serrados son las lesiones precursoras de cáncer de colon surgiendo desde la vía CIMP.
