Resumen
Introducción

Diseñamos un estudio prospectivo aleatorizado con el fin de determinar la utilidad de la radioterapia (RT) postoperatoria, en términos de control loco-regional y de supervivencia, en el tratamiento de los pacientes con carcinoma epidermoide localmente avanzado (estadios III y IV) con bordes quirúrgicos libres y sin extensión extracapsular en los ganglios cervicales positivos

Material y métodos

Entre 1994 y 1995, 51 pacientes fueron incluidos en el estudio, de los cuales 42 fueron considerados evaluables (de los cuales 21 recibieron RT postoperatoria). Se requirió un seguimiento mínimo de 3 años para ser incluidos en el estudio

Resultados

La tasas de recidiva loco-regional fueron idénticas en el grupo de pacientes radiados y no radiados (15/21 casos -70%- en cada grupo), al igual que la supervivencia específica para la enfermedad a los 5 años (35% para ambos grupos). El único parámetro asociado significativamente con una menor supervivencia fue la presencia de metástasis ganglionares

Conclusión

Nuestros resultados sugieren que la RT postoperatoria no aumenta el control loco-regional ni la supervivencia en los pacientes con carcinoma epidermoide de cabeza y cuello en estadios avanzados cuando ha sido totalmente resecado

Abstract
Introduction

A prospective randomised clinical trial was designed to assess the usefulness of postoperative radiotherapy (RT) in terms of loco-regional control and survival in patients with surgically treated advanced (stages III to IV) head and neck squamous cell carcinoma with negative margins and without extracapsular extension in positive neck nodes

Materials and methods

Between 1994 and 1995, 51 patients were included in the study and 42 were considered evaluables (from which 21 received postoperative RT). A minimum follow- up of 3 years was required

Results

The loco-regional recurrence rates were identical in irradiated and non-irradiated patients (15/21 cases -70%- in each group), as was the 5-year disease-specific survival (35% for both groups). The only parameter that was associated with a reduced disease-specific survival was the presence of regional lymph node metastases

Conclusion

Our results suggest that postoperative RT does not increase loco-regional control or survival in patients with completely resected advanced head and neck squamous cell carcinoma
