    BackgroundPatients undergoing chemotherapy are at risk for mucosal injury and neutropenia, which facilitate colonic mucosal invasion by the bowel flora and subsequent neutropenic enterocolitis, which has a poor prognosis.ObjectiveThis study aimed to assess the clinical features and outcomes of neutropenic enterocolitis in patients at a comprehensive cancer center.DesignThis is a retrospective cohort study.SettingThe study was conducted at the University of Texas MD Anderson Cancer Center.PatientsNeutropenic enterocolitis was defined by the presence of an absolute neutrophil count <1000/mm, compatible abdominal symptoms, and either mucosal thickening on abdominal imaging or mucosal injury on colon biopsy. Patients who had been diagnosed between 2010 and 2018 were included.Main OutcomesComplication and survival rates were analyzed using logistic regression and Cox regression analyses, respectively.ResultsOf the 49,244 patients who had neutropenia during the study period, 134 (2.7%) were included. The median time from neutropenia onset to neutropenic enterocolitis was 2 days (interquartile range, 1-10 days). Neutropenic enterocolitis symptoms lasted for a median of 11 days (interquartile range, 6-22 days). Most patients received antibiotics (88%) and granulocyte colony-stimulating factor (68%). Complications included sepsis (11%), colonic perforation (2%), pneumatosis intestinalis (2%), and abscess formation (2%). The risks associated with complications included immunosuppressive therapy use within 1 month before neutropenic enterocolitis onset (OR, 3.92; 95% CI, 1.04-14.76) and delayed imaging (OR, 1.10; 95% CI, 1.03-1.17). Older age, severe neutropenia, prolonged neutropenia before and after neutropenic enterocolitis diagnosis, and other concomitant systemic infections were associated with lower survival rates.LimitationsThe performance of this study at a single center and its retrospective nature are limitations of the study.ConclusionThe prompt diagnosis and management of neutropenic enterocolitis are critical to prevent complications. The use of granulocyte colony-stimulating factor can be beneficial to shorten the duration of neutropenia. See Video Abstract at http://links.lww.com/DCR/B116. ENTEROCOLITIS NEUTROPÉNICA: CARACTERÍSTICAS CLÍNICAS Y RESULTADOS: Los pacientes sometidos a quimioterapia, están en riesgo de lesión de la mucosa y neutropenia, lo que facilita la invasión de la mucosa colónica por la flora intestinal y la subsecuente enterocolitis neutropénica, con un mal pronóstico.Evaluar las características clínicas y los resultados de la enterocolitis neutropénica de pacientes en un centro integral de cáncer.Estudio de cohorte retrospectivo.El estudio se realizó en el MD Anderson Cancer Center de la Universidad de Texas.Se definió la enterocolitis neutropénica, como la presencia de un recuento absoluto de neutrófilos <1000 / mm3, con síntomas compatibles abdominales y engrosamiento de la mucosa en imagen abdominal o lesión de la mucosa en biopsia de colon. Se incluyeron pacientes diagnosticados entre 2010 y 2018.Se analizaron las tasas de complicaciones y supervivencia mediante análisis de regresión logística y regresión de Cox.De 49,244 pacientes que tuvieron neutropenia durante el período de estudio, 134 (2.7%) fueron incluidos. La media del tiempo desde el inicio de la neutropenia hasta la enterocolitis neutropénica, fue de 2 días (RIC, 1-10 días). Los síntomas de enterocolitis neutropénica duraron una media de 11 días (RIC, 6-22 días). La mayoría de los pacientes recibieron antibióticos (88%) y factor estimulante de colonias de granulocitos (68%). Las complicaciones incluyeron sepsis (11%), perforación colónica (2%), neumatosis intestinal (2%) y formación de abscesos (2%). Los riesgos asociados con las complicaciones incluyeron, uso de terapia inmunosupresora dentro de 1 mes antes del inicio de la enterocolitis neutropénica (razón de probabilidades 3.92; intervalo de confianza del 95% 1.04-14.76) y demora en la obtención de imágenes (razón de probabilidades 1.10; intervalo de confianza del 95% 1.03-1.17), edad avanzada, neutropenia grave, neutropenia prolongada antes y después del diagnóstico de enterocolitis neutropénica y de otras infecciones sistémicas concomitantes, se asociaron con bajas tasas de supervivencia.Centro único y estudio retrospectivo.El rápidodiagnóstico y manejo de la enterocolitis neutropénica, es crítico para prevenir complicaciones. El uso del factor estimulante de colonias de granulocitos puede ser beneficioso para acortar la duración de la neutropenia. Consulte Video Resumen en http://links.lww.com/DCR/B116.
