Overview

El tumor neuroendocrino de recto es una neoplasia rara que alcanza una incidencia entre el 1% y el 4 % en las diferentes series. La prevalencia de estos tumores es dificil de determinar. Constituyen el tipo histologico mas agresivo entre las neoplasias rectales, siendo los de diseminacion mas precoz y pronostico mas infausto. La clinica de presentacion de estos tumores no difiere de la de los adenocarcinomas de colon. Sin embargo, podemos hallar en el momento del diagnostico un estadiaje del tumor mas avanzado. Son el dolor abdominal, la hematoquecia, las alteraciones del habito intestinal, la sangre oculta en heces o la presencia de una masa los signos y sintomas que ponen al clinico en alerta, y raramente existen sintomas de sindrome paraneoplasico, carcinoide ni anormalidades metabolicas. El higado es el primer lugar de asiento de las metastasis, como en los adenocarcinomas de tipo exocrino. El diagnostico precoz puede mejorar la supervivencia de los pacientes, siendo la cirugia, mediante diferentes tecnicas el unico tratamiento efectivo hasta el momento. Medidas paliativas quirurgicas como la confeccion de colostomias o los tratamientos radioterapicos deben ser evaluadas para mejorar la calidad de vida del paciente afecto de estos tumores.
