Summary: | Introduction: The cecal appendix is the second most common site for neuroendocrine tumors in all of the digestive tract, with a relative rate of 25-30%. They are usually diagnosed incidentally during appendectomies or other abdominal surgeries. Objectives: To analyze a series of cases of appendix neuroendocrine tumors treated at the Abdominal-pelvic Surgery Service of the Brazilian National Cancer Institute and describe the approach used in this Service for the treatment of this group of neoplasms. Material and Methods: Report of a series of 13 cases, through the retrospective analysis of the medical records of patients with appendix neuroendocrine tumors treated at the Abdominal-pelvic Surgery Service of the Brazilian National Cancer Institute from 1996 to 2008. Results: The average age at diagnosis was 44.7, with a predominance of women over men in a ratio of 5.5:1. Tumor size ranged from 0.3 to 6 cm, with a median of 2.3 cm. After an average follow up of 32 months, 10 (77%) patients were alive, one (7.7%) missed the follow-up and two (15.3%) died. Conclusion: Appendix neuroendocrine tumors are relatively rare and have good prognosis. The simple appendectomy is the routine surgical treatment and provides cure in most cases. The criteria proposed by the European Neuroendocrine Tumor Society for the treatment of these tumors are easily reproducible and are currently being used as routine in this Service. |

Introducción: El apéndice cecal es el segundo sitio más frecuente de aparición de los tumores neuroendocrinos en todo el tracto digestivo, con una frecuencia relativa de 25-30%. Por lo general, son diagnosticados de forma incidental durante las apendicectomías u otras cirugías abdominales. Objetivos: Analizar una serie de casos de tumores neuroendocrinos de apéndice tratados en el Servicio de Cirugía Abdominopélvica del Instituto Nacional del Cáncer y describir el enfoque adoptado en este Servicio para el tratamiento de este grupo de neoplasias. Material y métodos: Informe de una serie de 13 casos por análisis retrospectivo de prontuarios de pacientes con tumores neuroendocrinos del apéndice atendidos en el Servicio de Cirugía Abdominopélvica del Instituto Nacional del Cáncer, en el período desde 1996 hasta 2008. Resultados: La edad media de los pacientes al diagnóstico fue de 44,7 años, con un predominio del sexo femenino sobre el masculino en una proporción de 5,5:1. El tamaño tumoral osciló entre 0,3 a 6 cm con una mediana de 2,3 cm. Tras un seguimiento medio de 32 meses, diez (77%) pacientes estaban vivos, uno (7,7%) perdió el seguimiento y dos (15,3%) fallecieron. Conclusión: Los tumores neuroendocrinos apendiculares son relativamente raros y de bueno pronóstico. La apendicectomía simple es el tratamiento quirúrgico de rutina y proporciona la cura en la mayoría de los casos. Los criterios propuestos por European Neuroendocrine Tumor Society para el tratamiento de estos tumores son fáciles de reproducir y, actualmente, se adoptan como rutina en ese Servicio.
