ABSTRACT

Introduction: The effectiveness of an elemental diet (ED) for preventing adverse events (AEs) during chemotherapy for patients with esophageal cancer (EC) remains unclear. The aim of this meta-analysis was to comprehensively assess the efficacy of ED for preventing AE in EC patients during chemotherapy. Medline (via PubMed), Embase, the Cochrane Library, and Web of Science were searched to retrieve prospective and randomized studies published before April 12, 2023. The odds ratio (OR) of each AE was calculated using Review Manger 5.4.1. The risk of bias was assessed, and a random effect model-based meta-analysis was used to analyze the available data. Four prospective and randomized studies involving 237 patients were identified after a systematic search. Regarding gastrointestinal toxicities, the findings indicated a trend toward a decrease in the risk of mucositis (OM) (OR = 0.54, 95 % CI: 0.25-1.14), constipation (OR = 0.87, 95 % CI: 0.49-1.53), and anorexia (OR = 0.99, 95 % CI: 0.32-3.05), as well as an increasing trend in the risk of diarrhea (OR = 1.48, 95 % CI: 0.79-2.79), among patients treated with ED. However, none of these reached statistical significance. For hematological toxicities, the risk of all-grade neutropenia (OR = 0.28, 95 % CI: 0.14-0.57), grade ≥ 2 leucopenia (OR = 0.43, 95 % CI: 0.22-0.84), grade ≥ 2 neutropenia (OR = 0.34, 95 % CI: 0.17-0.67), and grade ≥ 3 neutropenia (OR = 0.28, 95 % CI: 0.12-0.63) was significantly decreased. There is no firm evidence confirming the preventive effect of an ED against OM or diarrhea. However, an ED may potentially be helpful in preventing neutropenia and leucopenia.


Introducción: La efectividad de una dieta elemental (DE) para prevenir eventos adversos (EA) durante la quimioterapia en pacientes con cáncer de esófago (CE) sigue sin estar clara. Este metaanálisis evalúa la eficacia de DE para prevenir EA en pacientes con CE durante quimioterapia. Se realizaron búsquedas en Medline (con PubMed), Embase, Biblioteca Cochrane y Web of Science para recuperar estudios prospectivos y aleatorios publicados antes del 12/04/2023. La razón de probabilidad (RP) de cada EA se calculó usando Review Manger 5.4.1. Se evaluó el riesgo de sesgo y se utilizó un metaanálisis basado en modelo de efectos aleatorios para analizar los datos disponibles. Después de una búsqueda sistemática, se identificaron cuatro estudios prospectivos y aleatorios con 237 pacientes. En cuanto a las toxicidades gastrointestinales, los hallazgos indicaron una tendencia hacia una disminución en el riesgo de mucositis (OM) (OR = 0,54, IC 95 %: 0,25-1,14), estreñimiento (OR = 0,87, IC 95 %: 0,49-1,53) y anorexia (OR = 0,99, IC 95 %: 0,32-3,05) y una tendencia creciente en el riesgo de diarrea (OR = 1,48, IC 95 %: 0,79-2,79) entre los pacientes tratados con DE. Sin embargo, no hubo muestras estadísticas significativas. Para toxicidades hematológicas, el riesgo de neutropenia de todos los grados (RP = 0,28; IC del 95 %: 0,14-0,57), leucopenia grado ≥ 2 (RP = 0,43; IC del 95 %: 0,22-0,84), neutropenia grado ≥ 2 (RP = 0,34; IC del 95 %: 0,17-0,67) y neutropenia grado ≥ 3 (RP = 0,28; IC del 95 %: 0,12-0,63) disminuyó significativamente. Ninguna evidencia firme confirmó el efecto preventivo de DE frente a OM o la diarrea. Una DE sería útil previniendo neutropenia y leucopenia.
