Malnutrition is a significant risk factor for immunosuppression, negatively impacting immune response and postoperative recovery capacity. At the time of the surgeries, due to their wide scope and aggressive treatments such as chemotherapy and radiotherapy, the situation becomes more serious. Those micronutrients taking part in immunonutrition, namely, arginine, omega-3 fatty acids, nucleotides, and antioxidants, have the potential to prevent inflammation, protect against infections, and promote healing after the surgery. Research has shown that immunonutrition can lower the risk of postoperative infection, promote the normal healing of wounds, and reduce the hospital stays of patients, as well as support malnutrition status during chemotherapy. This review is based on a literature search conducted in Medline, Scopus, Clinicaltrials.gov, Cochrane CENTRAL, and Google Scholar, with the last search date being November 2024. Some studies. found that perioperative immunonutrition decreases wound infections and affects some immune indexes in gynecologic oncology patients positively. However, factors such as non-compliant patients, high costs, and non-standard formulations can deter its wider use. Patient adherence drops postoperatively mainly due to nausea and decreased appetite, whereas the cost of enriched formulations acts as an economic barrier. Postoperative compliance drops from ~78% prior to surgery to ~28% due to nausea, anorexia, and chemotherapy. Additionally, cost remains a constraining factor since special formulas are 2\u20134 times that of normal nutrition. While immunonutrition reduces hospital stay (by ~2\u20133 days) and infection rate (by 25\u201340%), access is hindered by prohibitive initial costs and lack of insurance coverage. Approaches such as subsidized schemes, enhanced palatability, and cost\u2013benefit analyses are required to increase adoption. In addition, the lack of standardized protocols makes the clinical community hesitant to adopt this approach. Immunonutrition is, despite these problems, still hoped to be the new adjunct to gynecologic oncology patients. In future studies, it is imperative to pay attention to the best formulations that produce the best outcomes and evaluate and implement guidelines that are based on evidence. Together, with these improvements, immunonutrition could very well be an integral part of perioperative care thus completing the process by which patients in intense treatments are benefited not only via treatment but also via quality of life.<\/jats:p>","DOI":"10.3390\/life15030487","type":"journal-article","created":{"date-parts":[[2025,3,18]],"date-time":"2025-03-18T04:34:43Z","timestamp":1742272483000},"page":"487","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Immunonutrition in ERAS Protocol for Patients with Gynecologic Cancer: A Narrative Review of the Literature"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-2323-2563","authenticated-orcid":false,"given":"Vasilios","family":"Lygizos","sequence":"first","affiliation":[{"name":"First Department of Obstetrics and Gynecology, Division of Gynecologic Oncology, \u201cAlexandra\u201d General Hospital, National and Kapodistrian University of Athens, 115 28 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dimitrios","family":"Haidopoulos","sequence":"additional","affiliation":[{"name":"First Department of Obstetrics and Gynecology, Division of Gynecologic Oncology, \u201cAlexandra\u201d General Hospital, National and Kapodistrian University of Athens, 115 28 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3740-2575","authenticated-orcid":false,"given":"Dimitrios Efthymios","family":"Vlachos","sequence":"additional","affiliation":[{"name":"First Department of Obstetrics and Gynecology, Division of Gynecologic Oncology, \u201cAlexandra\u201d General Hospital, National and Kapodistrian University of Athens, 115 28 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-8725-7103","authenticated-orcid":false,"given":"Antonia","family":"Varthaliti","sequence":"additional","affiliation":[{"name":"First Department of Obstetrics and Gynecology, Division of Gynecologic Oncology, \u201cAlexandra\u201d General Hospital, National and Kapodistrian University of Athens, 115 28 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Fanaki","sequence":"additional","affiliation":[{"name":"First Department of Obstetrics and Gynecology, Division of Gynecologic Oncology, \u201cAlexandra\u201d General Hospital, National and Kapodistrian University of Athens, 115 28 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7108-211X","authenticated-orcid":false,"given":"George","family":"Daskalakis","sequence":"additional","affiliation":[{"name":"First Department of Obstetrics and Gynecology, Division of Gynecologic Oncology, \u201cAlexandra\u201d General Hospital, National and Kapodistrian University of Athens, 115 28 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nikolaos","family":"Thomakos","sequence":"additional","affiliation":[{"name":"First Department of Obstetrics and Gynecology, Division of Gynecologic Oncology, \u201cAlexandra\u201d General Hospital, National and Kapodistrian University of Athens, 115 28 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vasilios","family":"Pergialiotis","sequence":"additional","affiliation":[{"name":"First Department of Obstetrics and Gynecology, Division of Gynecologic Oncology, \u201cAlexandra\u201d General Hospital, National and Kapodistrian University of Athens, 115 28 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"215","DOI":"10.1159\/000451063","article-title":"Nutrition status, nutrition support therapy, and food intake are related to prolonged hospital stays in China: Results from the NutritionDay 2015 survey","volume":"69","author":"Zheng","year":"2016","journal-title":"Ann.
