Effect of preoperative immunonutrition on postoperative short-term clinical outcomes in patients with gastric cancer cachexia: a prospective randomized controlled trial
Abstract
Although current guidelines(ESPEN guideline: Clinical nutrition in surgery and other guidelines) recommend preoperative immunonutrition for cachectic gastric cancer patients, the strength of the recommendation is weak, and the level of evidence is low. The benefits of preoperative immunonutrition still remain controversial. 112 patients with gastric cancer cachexia were enrolled in the study and randomly assigned in a 1:1 ratio to receive either preoperative enteral immunonutrition support (IN, n = 56) or standard enteral nutrition support (SEN, n = 56). The primary endpoint was the incidence of infectious complications, and the secondary endpoints included the nutritional indicators, inflammatory markers, immune parameters, postoperative recovery and complications and gastrointestinal intolerance reactions. The incidence of postoperative infectious complications(P = 0.040) and overall complications (P = 0.049)was significantly lower in the IN group compared to the SEN group. In terms of laboratory inflammatory indexes, patients in the IN group demonstrated significantly lower levels of white blood cells (WBC), C-reactive protein (CRP), and interleukin-6 (IL-6), as well as higher levels of lymphocytes (LYMPH) and immunoglobulin A (IgA), compared to patients in the SEN group, with statistically significant differences. In terms of clinical outcomes, the IN group had a shorter duration of antibiotic use (P = 0.048), shorter hospital stay (P = 0.018), and lower total hospital…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 112 participants or records.
