- Abstract : BACKGROUND: Anal adenocarcinoma is a rare clinical entity for which the optimal management is not defined. OBJECTIVE: This study aimed to describe the multidisciplinary management and outcomes of patients with anal adenocarcinoma. DESIGN: This is a retrospective cohort study. SETTING: This study was conducted at a quaternary cancer center. PATIENTS: Men and women with anal adenocarcinoma treated between 1995 and 2016 were selected. INTERVENTIONS: Fifty-two patients were treated with either chemoradiotherapy or trimodality therapy including radiation therapy, chemotherapy, and surgical resection. MAIN OUTCOME MEASURES: Local failure, regional failure, and distant metastasis rates were estimated using the cumulative incidence method. The Kaplan-Meier method was used to estimate progression-free survival and overall survival. The multivariable Cox proportional hazards model was used to evaluate the clinical predictors of outcome RESULTS: There was a higher 5-year rate of local failure in patients treated with chemoradiotherapy compared with trimodality therapy (53% vs 10%; p < 0.01). The 5-year incidence of distant metastases was 29% (trimodality therapy) versus 30% (chemoradiotherapy; p = 0.9); adjuvant chemotherapy did not reduce the incidence of distant metastases ( p = 0.8). Five-year overall survival was 73% (trimodality therapy) versus 49.4% (chemoradiotherapy; p = 0.1). On multivariable analysis, factors associated with worse overall survival were treatmentAbstract : BACKGROUND: Anal adenocarcinoma is a rare clinical entity for which the optimal management is not defined.

Five-year overall survival was 73% (trimodality therapy) versus 49.4% (chemoradiotherapy; p = 0.1). On multivariable analysis, factors associated with worse overall survival were treatment with chemoradiotherapy, cT3-4 category disease, and node-positive disease. LIMITATIONS: This study is limited by its small sample size and retrospective nature. CONCLUSIONS: Although treatment may continue to be tailored to individual patients, better outcomes with a trimodality therapy approach were observed.

ADENOCARCINOMA ANAL: UNA ENTIDAD POCO FRECUENTE EN NECESIDAD DE UN MANEJO MULTIDISCIPLINARIO ANTECEDENTES: El adenocarcinoma anal es una entidad clínica poco frecuente por lo que aún no se define el manejo óptimo. OBJETIVO: Describir el manejo multidisciplinario y los resultados de los pacientes con adenocarcinoma anal. DISEÑO: Estudio de cohorte retrospectivo. ENTORNO CLINICO: Centro de cáncer cuaternario. PACIENTES: Hombres y mujeres con adenocarcinoma anal tratados entre 1995 y 2016. INTERVENCIONES: Cincuenta y dos pacientes fueron tratados con quimiorradioterapia o terapia trimodal que incluyó: radioterapia, quimioterapia y resección quirúrgica. PRINCIPALES MEDIDAS DE VALORACION: Se estimaron las tasas de falla local, falla regional y metástasis a distancia mediante el método de incidencia acumulada. Se utilizó el método de Kaplan-Meier para estimar la supervivencia libre de progresión y la supervivencia global. Los riesgos proporcionales de multivariable Cox se utilizaron para evaluar los predictores clínicos de los resultados. RESULTADOS: Hubo una mayor tasa de falla local a cinco años en pacientes tratados con quimiorradioterapia en comparación con terapia trimodal (53% vs 10%; p < 0, 01). La incidencia a cinco años de metástasis a distancia fue del 29% (terapia trimodal) versus 30% (quimiorradioterapia) ( p = 0, 9); la quimioterapia adyuvante no redujo la incidencia de metástasis a distancia ( p = 0, 8). La supervivencia global a cinco años fue del 73% (terapia trimodal) versus 49, 4% (quimiorradioterapia); p = 0, 1. En el análisis multivariable, los factores asociados con una peor supervivencia general fueron el tratamiento con quimiorradioterapia, enfermedad de categoría cT3-4 y enfermedad con ganglios positivos. LIMITACIONES: Este estudio está limitado por su pequeño tamaño de muestra y su naturaleza retrospectiva. CONCLUSIONES: Aunque el tratamiento puede seguir adaptándose a pacientes individuales, se observaron mejores resultados con un enfoque TTM. Conslute Video Resumen en http://links.lww.com/DCR/B708 .
