Resumen

Los pólipos hiperplásicos en el colon se han considerado tradicionalmente lesiones benignas sin riesgo de malignización. Sin embargo, los pólipos hiperplásicos son sólo una parte del espectro de los llamados pólipos serrados, que incluyen diferentes subtipos de lesiones con una característica histológica común, la apariencia “en dientes de sierra”, con potencial de transformación a carcinoma colorrectal a través de la llamada “vía serrada”. Por tanto, la identificación y resección de estas lesiones, así como el seguimiento de estos pacientes, es fundamental para la prevención de esta neoplasia. Los estudios presentados este año en el congreso de la American Gastroenterological Association aportan información relevante para caracterizar mejor estas lesiones, particularmente importantes para la prevención del cáncer colorrectal, y establecer programas de vigilancia adecuados.

Abstract

Hyperplastic polyps of the colon have traditionally been considered benign lesions without risk of progression to malignancy. However, hyperplastic polyps are only part of the spectrum of polyps known as serrated polyps. These polyps, which share a common sawtooth appearance, include distinct subtypes of lesions that can potentially undergo malignant transformation to colorectal carcinoma through the serrated pathway. Therefore, to prevent this process, affected patients must undergo surveillance and lesions must be identified and resected. Studies presented this year at the congress of the American Gastroenterological Association have provided useful information to better characterize these lesions –particularly important for the prevention of colorectal cancer– and to establish appropriate surveillance strategies.
