The Effects of Immunonutrition Therapy on Locally Advanced Cervical Cancer Patients

Malnutrition is one of the most common complications in patients with Locally Advanced Cervical Cancer (LACC) undergoing radical concurrent chemoradiotherapy (CCRT). Tumor patients often experience significant immune imbalance, metabolic abnormalities, and inflammatory responses. Immunonutrition therapy involves the use of specific immunonutrients such as polyunsaturated fatty acids, arginine, nucleotides, etc., to prevent and correct malnutrition in cancer patients, regulate immune function, alleviate harmful or excessive inflammatory responses, and thereby improve patients' clinical outcomes. This study is an open-label randomized controlled trial, including patients with LACC who all receive radical radiotherapy. Using the Nutritional Risk Screening 2002 (NRS2002) at screening, patients identified as having nutritional risk are further assessed by nutritionists and physicians using the Patient-Generated Subjective Global Assessment (PG-SGA) score and modified Global leadership initiative on malnutrition (GLIM) criteria. Patients with moderate or severe malnutrition are randomly allocated into the enteral immunonutrition therapy group (experimental group) and the standard enteral nutrition support group (control group). The experimental group receives immunonutrients per day, while the control group receives isoenergetic standard oral enteral nutrition. Upon admission, all patients receive nutritional education from specialized nurses and consult with nutritionists, and nutritional support is provided during the concurrent chemoradiotherapy for a total of 5 weeks (W0-W5).GLIM score, quality of life score and peripheral blood inflammation and immune indicators were collected within 48 hours after admission (before treatment), W5, W8, and W20; CTCAE v 5.0 score was used for treatment side effects.
