Resumen

Los pacientes con carcinoma de laringe en estadios avanzados tienen un alto riesgo de desarrollar metástasis a distancia, lo cual ensombrece considerablemente el pronóstico. En nuestro estudio tratamos de identificar cuáles son los factores de riesgo y planteamos someter a este grupo de pacientes a un tratamiento sistémico más agresivo. Analizamos los datos de 57 pacientes con carcinoma escamoso faringolaríngeo en estadios III y IV, tratados quirúrgicamente. Encontramos que los estadios T avanzados y la afectación cervical ganglionar causan más metástasis (p < 0,05), así como la invasión tumoral de 3 o más ganglios (p=0,002),y los tumores pobremente diferenciados (p < 0,05). La localización tumoral, su extensión en cm, la presencia de ulceración y la falta de control locoregional no se asociaron con una mayor incidencia de metástasis.

Abstract

Patients with advanced stage cancer larynx have a higher risk of development of distant metastases wich means a bad prognosis. In our study we try to identify risk factors with the idea of involve to all of these patients in more aggresive systemic thera py protocols. Data of 57 patients surgically treated, with squamous pharyngolaryngeal carcinoma, stage III and IV, are evaluated. Advanced T stage or more extensive neck disease more often caused distant metastases (p < 0.05), and also the histological evidence of tumor invasion in three or more cervical nodes (p=0.02), and poorly differentiated tumors (p < 0.05). Tumor site, surface area in cm, presence of ulceration, and loco-regional uncontrol were not associated with distant metastases.
