Optimal nutritional management is imperative to enhance the efficacy of both chemotherapeutic and surgical interventions. In this article, various methods for nutritional screening and assessment, including a range of biochemical assays and decision-making frameworks relevant to clinical settings. We have described pre- and postoperative nutritional strategies and highlighted the established practical guidelines. Additionally, we investigated the key aspects of nutritional oversight during oncological treatment and emphasize the significance of a multidisciplinary approach that involves the services of physicians, dietitians, and nurses.
