Abstract
Introduction

Head and neck chondrosarcomas may adopt different locations and biological behaviour.

Material and method

We present a retrospective clinical series of 17 chondrosarcomas surgically treated in our Department from 1977 until 2006.

Results

Chondrosarcomas were located in the nasosinusal area (n=6), larynx (n=5), petrous bone (n=3), atlas (n=1), parapharyngeal space (n=1) and trachea (n=1). All patients except for one underwent surgery with radical intention. The mean follow-up period was 84 months (median, 71 months). Six patients developed recurrent disease with a mean latency of 10 months. Two patients died due to the disease and two remained alive with evidence of tumour. Patients with grade I chondrosarcomas presented less recurrent disease than those with grade II or III chondrosarcomas (17% vs 80%, P=.029). The estimated 5-year survival was 88%, with the better survival of patients with grade I chondrosarcomas reaching statistical significance (P=.023). In 2 patients with cricoid chondrosarcomas, the reconstruction was carried out using the Rethi-Ward technique, and they were without evidence of disease at 71 months (with no cannula) and 145 months (with cannula). Chondrosarcomas of the jugular foramen were treated using a modified type A infratemporal approach.

Conclusion

Low grade head and neck chondrosarcomas have a good prognosis, while high grade chondrosarcomas tend to recur, despite radical surgical treatment.

Resumen
Introducción

Los condrosarcomas de cabeza y cuello adoptan una gran variedad de localizaciones y comportamientos biológicos.

Material y método

Se presenta una serie retrospectiva de 17 casos de condrosarcomas de cabeza y cuello tratados quirúrgicamente en nuestro servicio desde 1977 hasta 2006.

Resultados

Los condrosarcomas se localizaron en el área nasosinusal (n=6), laringe (n=5), peñasco (n=3), atlas (n=1), espacio parafaríngeo (n=1) y tráquea (n=1). Todos excepto una paciente se sometieron a cirugía con intención radical. El periodo de seguimiento medio fue de 84 meses (mediana, 71 meses). Se produjo recidiva en 6 pacientes con una latencia media de 10 meses. Dos pacientes fallecieron a causa de la enfermedad y dos permanecieron vivos con enfermedad. Los pacientes con condrosarcomas de grado I presentaron menos recidivas que los grados II y III (17% frente a 80%, p=0,029). La supervivencia media estimada a los 5 años fue del 88% siendo estadísticamente significativa la mayor supervivencia en los pacientes con tumores de grado I (p=0,023). En 2 pacientes con condrosarcomas cricoideos la reconstrucción se llevó a cabo mediante la técnica de Rethi-Ward, encontrándose sin evidencia de la enfermedad a los 71 (decanulado) y 145 meses (no decanulado). Los condrosarcomas de la fosa yugular fueron tratados mediante el abordaje infratemporal tipo A modificado.

Conclusiones

Los condrosarcomas de cabeza y cuello de bajo grado presentan un buen pronóstico vital. Los de alto grado, pese al tratamiento radical, tienden a la recidiva.
