Colangiocarcinoma - Overview

Nombres alternativos

Cáncer de las vías biliares

Definición:

Es un tumor canceroso (maligno) en uno de los conductos que llevan la bilis desde el hígado hasta el intestino delgado.

Causas, incidencia y factores de riesgo:

Los tumores cancerosos de las vías biliares suelen ser de crecimiento lento y no se diseminan (hacen metástasis) rápidamente. Sin embargo, muchos de los tumores ya están avanzados para el momento cuando los encuentran.

Un colangiocarcinoma puede aparecer en cualquier lugar a lo largo de las vías biliares. Estos tumores obstruyen dichas vías biliares.

Este tumor afecta a personas de ambos sexos y la mayoría de los pacientes tienen más de 65 años de edad.

Los factores de riesgo para esta afección abarcan:

  • Quistes colédocos (de las vías biliares)
  • Irritación biliar crónica
  • Antecedentes de infección con los parásitos trematodos hepáticos
  • Colangitis esclerosante primaria
  • Colitis ulcerativa

El colangiocarcinoma es una enfermedad rara que se presenta aproximadamente en 2 de cada 100,000 personas.
