RESUMO
INTRODUCCIÓN: Los tumores neuroendocrinos (TNE) representan un grupo de neoplasias originadas por células de la cresta neural y del endodermo con gran heterogenicidad en cuanto a localización, comportamiento clínico, agresividad y pronóstico. El páncreas y el tubo digestivo constituyen las localizaciones más frecuentes. MATERIAL Y MÉTODOS: Se ha realizado una revisión de casos diagnosticados de neoplasia neuroendocrina gastroenteropancreática (TNEGEP), tanto primaria como metastásica, en el Hospital Universitario Clínico San Carlos (HUCSC) entre enero de 2007 y mayo de 2012. Se han comparado los datos obtenidos con los aportados por el Registro del Grupo Español de Tumores Neuroendocrinos (RGETNE). RESULTADOS: El estudio constó de 78 pacientes. El tipo de tumor más común fue el gastroentérico no funcionante. Un 50,6% de los pacientes presentó metástasis al diagnóstico, siendo lo más prevalente la afectación ganglionar. Los TNEGEP localizados en el recto se acompañaron de un mayor porcentaje de metástasis. La supervivencia global a los 24 meses fue del 74,8%, estando en relación con el sexo, la expresión del Ki-67 y la presencia de enfermedad a distancia
INTRODUCTION: Neuroendocrine tumors are a group of neoplasms arising from the neural crest and endoderm and very heterogeneous as regards localization, clinical behavior, aggressiveness, and prognosis. Pancreas and gastrointestinal tract are the most common sites where neuroendocrine tumors can be found. MATERIAL AND METHODS: A review was made of all cases of neuroendocrine tumors diagnosed at Hospital Universitario Clínico San Carlos (HUCSC) from January 2007 to May 2012. Data were compared to the results provided by the Registry of the Spanish Group on Neuroendocrine Tumors (RGETNE). RESULTS: The study cohort comprised 78 patients. Gastroenteric nonfunctional tumors were the most common neoplasms. Metastases were found at diagnosis in 50.6% of patients, with nodal involvement being most prevalent. Tumors located in the rectum were associated to the highestrate of metastasis. Overall 2-year survival rate was 74.8% and was related to sex, Ki-67 expression, and presence of metastasis
