Nutritional status has emerged as a significant factor influencing the prognosis and survival of CRC patients. This comprehensive literature review examines the role of nutritional support in improving treatment outcomes, including the efficacy of interventions, patient quality of life (QoL), and the modulation of inflammatory responses. The findings suggest that tailored nutritional interventions improve clinical outcomes, enhance QoL, and reduce treatment-related complications, particularly by attenuating inflammation. Furthermore, the review highlights the cost-effectiveness of nutritional strategies and identifies key methods to enhance patient compliance with dietary recommendations. In conclusion, integrating nutritional support into CRC treatment plans is crucial for optimizing clinical management and improving patient well-being.  \nKeywords: colorectal cancer; nutritional interventions; postoperative complications; quality of life  \n1. Introduction  \nColorectal cancer (CRC) is one of the most prevalent forms of cancer worldwide, with significant morbidity and mortality rates [1] . The prognosis and survival rates for CRC patients are influenced by various factors, including the stage at diagnosis, treatment modalities, and patient-related factors such as age, comorbidities, and nutritional status. Among these, nutritional status has emerged as a critical determinant of treatment outcomes, influencing both the efficacy of therapeutic interventions and the overall quality of life (QoL) of patients. Nutritional interventions before and after surgery, as well as during other treatment modalities like chemotherapy, play a pivotal role in enhancing the body’s resilience to the stress of cancer treatments, supporting immune function, and promoting recovery.
