Abstract Background In recent years, preoperative nutrition has received great attention, especially for patients who received surgical reconstruction of the digestive tract such as esophagectomy. Preoperative nutrition therapy was reported to accelerate the patient's postoperative recovery. In addition, immune suppression, nausea, and vomiting may lead to poor immune and nutritional status of patients with esophageal cancer who underwent neoadjuvant chemotherapy (NAC), which is not conducive to surgery. Therefore, preoperative nutritional treatment is necessary for patients with esophageal cancer who underwent NAC. Method Patients with esophageal cancer who received NAC at Nanjing Jinling Hospital from January 2018 to September 2020 were retrospectively identified. Patients were divided into enteral immunonutrition (EIN) group (those who received a conventional diet and immunonutrition supplement, Peptisorb, Nutricia, 500 mL/day * 7 via oral intake), and control group (those who only received a conventional diet were divided into). The primary outcomes were immune and nutritional indicators changes, including immunoglobulin M (IgM), immunoglobulin A (IgA), immunoglobulin G (IgG), and albumin (ALB), which were measured at preoperative day (PRD) 7, PRD-1, postoperative day (POD) 1 and POD-7. The secondary outcomes were postoperative complications, adverse reactions, and length of hospital stay. Results A total of 124 eligible patients were included in the study, with 21 patients in EIN group. After 1:2 matching, significant difference in baseline characteristics between the two groups was not observed (EIN: n = 21, Control group: n = 42). Compared with the control group, the IgA is significantly increased in the EIN group at POD-7 (p = 0.017). However, we observed that the IgM level in the control group was significantly higher than those in the EIN group at POD-7 (p = 0.007). The incidence of pneumonia and total complications in the EIN group were significantly lower than those in control group (p = 0.024, p = 0.028, respectively). There is no significant difference in ALB and adverse reactions between two groups (p = 0.303, p = 0.108, respectively). Conclusion Immunonutritional supplement after NAC is an effective strategy to improve the postoperative immune status of esophageal cancer patients and could reduce the incidence of infectious complication. More well-designed prospective studies are needed to verify and update our finding.
