Carcinomas neuroendocrinos de colon y recto. Neuroendocrine carcinomas of the colon and rectum. A unit's experience over six years. Vilallonga, E. Landolfi 1 y M. Armengol Carrasco. Hospital Universitario Vall d'Hebron. Se han revisado de manera retrospectiva los pacientes con un tumor de estirpe neuroendocrina. Se han excluido los tumores carcinoides. Resultados: durante este periodo, se han intervenido 2.

Se localizaron uno en ciego, dos en recto y dos en sigma. Dos pacientes siguen vivos con un seguimiento medio de ocho meses. Palabras clave: Tumor. Carcinoma indiferenciado. Key words: Tumour. Undifferentiated carcinoma. Sin embargo, los tumores colorrectales neuroendocrinos se dividen en los de bajo grado o carcinoides y los tumores neuroendocrinos de alto grado.

CEA y CA El curso postoperatorio fue favorable. El tumor presentaba positividad para las queratinas y cromogranina. El paciente tuvo un postoperatorio correcto. Se intervino hallando una neoplasia de ciego exteriorizada, con carcinomatosis peritoneal y abundante ascitis.

El paciente no presenta a los diez meses ninguna recidiva local ni a distancia, y sigue tratamiento con 5-fluorouracilo y estreptomicina. El postoperatorio fue sin incidencias. El seguimiento no ha mostrado recidiva locorregional a los 10 meses de seguimiento. Sin embargo, estas localizaciones menos frecuentes han sido las halladas en nuestros pacientes. El origen y desarrollo de los tumores neuroendocrinos sigue siendo tema de controversia 5,10, A 5-decade analysis of 13, carcinoid tumors.

They are usually undifferentiated, easy to diagnose for the pathologist and are especially aggressive in their clinical behaviour.

Prognosis is usually poor and they have a high tendency to metastase early. Material and methods: we have reviewed our experience in a Colorectal Unit during a period of six years.

Patients with neuroendocrine tumours have been reviewed retrospectively. Carcinoid tumours have not been included in this study. Results: during this period, 2, patients have been operated for colorectal cancer and in five patients a neuroendocrine tumour has been found in the specimen.

Seven exemplars of piracanjuba, with average weight and standard length of The presence of endocrine cellules like "open" was verified on the segments related to the medium and posterior intestines omnivores species and like "closed" in the medium intestine and in the rectum of the carnivore specie. The argirofiles cellules were observed among the as absortive cellules of intestinal epithelium. The results showed that the presence of endocrine cellules can indicate that the studied species act in the absorption control mechanism of food nutrients. However, due to the obtained amounts, more studies are necessary to elucidate this control. Polak et al. Larsson , Lehy e Cristina e Tagliafierro et al.
