Comparison of Patients With Total and Salvage Laryngectomy.

INTRODUCTION AND OBJECTIVES: Total laryngectomy (TL) is one of the treatments available in locally advanced laryngeal carcinomas or as a salvage therapy when organ preservation fails, achieving high survival rates and few complications. The aim of this study was to analyse the oncological outcomes, comparing the data obtained with the current literature and analysing complications and survival. METHODS: The study included 62 patients with primary carcinoma of the larynx treated by primary or salvage TL between 2003 and 2019. We analysed the demographic, clinical and pathological characteristics, tumour stage, complementary treatments, postoperative complications, locoregional recurrences, metastases, and causes of death. RESULTS: The mean age was 64 years, 90.3% were men, 96.8% were smokers, 43.5% had multiple pathologies and 82.3% had a locally advanced stage. Of all TL 71% were primary and 29% salvage. Neck dissection was performed in 59.6%. Lymphovascular invasion was present in 30.6%, perineural invasion in 30.6% and margin involvement in 14.5%. During the follow-up, 17.7% presented locoregional recurrence and 11.3% distant metastases. Regarding complementary treatments, 56.4% of the patients received adjuvant therapy. The incidence of haemorrhage was 11.3%, infection 14.5%, and pharyngocutaneous fistula 21%. There was a statistically significant correlation between fistula and haemorrhage (P = .000) and between fistula and infection (P = .000). No statistically significant differences were found between the studied factors of primary and salvage TL. The 3-year overall survival was 92% and 5-year overall survival was 88%, finding statistical significance with the locally advanced stage (P = .038), T4 (P = .026), lymphovascular invasion (P = .019) and the involvement of more than 3 lymph nodes in the pathological anatomy (P = .005). On the multivariate analysis, the only variable that showed a significant relationship with survival was lymphovascular invasion (P = .026). CONCLUSIONS: Although organ preservation is a primary objective, TL remains a leading treatment in locally advanced carcinomas and as salvage in case of failure of medical therapy or partial surgery.

Comparación de pacientes con laringectomía total primaria y de rescate / Comparison of patients with total and salvage laryngectomy

Introducción y objetivos: La laringectomía total (LT) es uno de los tratamientos disponibles en los carcinomas de laringe localmente avanzados o como rescate ante el fracaso de la preservación de órgano, logrando altas tasas de supervivencia y escasas complicaciones. El objetivo de nuestro trabajo es analizar los resultados oncológicos obtenidos, comparándolos con la literatura actual y analizando sus complicaciones y supervivencia.MétodosSe incluyeron 62 pacientes con carcinoma primario de laringe tratados mediante LT primaria o de rescate entre los años 2003 y 2019. Analizamos las características demográficas, clínicas y anatomopatológicas, el estadio tumoral, los tratamientos complementarios, las complicaciones postoperatorias, las recidivas locorregionales, las metástasis y las causas de muerte.ResultadosLos pacientes tenían una edad media de 64 años, el 90,3% eran hombres, el 96,8% eran fumadores y el 43,5% tenían pluripatología. El 82,3% tenían un estadio localmente avanzado. Al 71% se les realizó LT primarias y al 29% de rescate. Al 59,6% se les practicó vaciamiento cervical asociado. El 30,6% tenían invasión linfovascular, el 30,6% invasión perineural y el 14,5% afectación de márgenes. Durante el seguimiento, el 17,7% presentaron una recidiva locorregional y el 11,3% metástasis a distancia. En cuanto a tratamientos complementarios, el 56,4% de los pacientes recibieron tratamiento adyuvante. La incidencia de hemorragia fue del 11,3%, la de infección del 14,5% y la de fístula faringocutánea del 21%. Hubo significación estadística entre la fístula y la hemorragia (p=0,000) y entre la fístula y la infección (p=0,000). No se encontraron diferencias estadísticamente significativas entre los factores estudiados de la LT primaria y de rescate.(AU)
