Vipoma - Overview

Nombres alternativos

Tumor productor de péptido intestinal vasoactivo; Tumor endocrino pancreático

Definición:

Es un tipo de cáncer muy poco común que generalmente crece a partir de células en el páncreas llamadas células de los islotes.

Causas, incidencia y factores de riesgo:

Los vipomas hacen que las células del páncreas produzcan altos niveles de una hormona llamada péptido intestinal vasoactivo (PIV). Esta hormona incrementa las secreciones de los intestinos y relaja algunos de los músculos lisos en el sistema gastrointestinal.

La causa se desconoce.

Los vipomas generalmente se diagnostican en adultos, con más frecuencia alrededor de los 50 años de edad y las mujeres tienen más probabilidad de resultar afectadas que los hombres. Este cáncer es poco común: afecta aproximadamente a 1 de cada 10 millones de personas por año.
