Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
In this multicenter, randomized, controlled clinical trial, approximately 360 postoperative CRC patients will be enrolled and randomly assigned to one of four groups: (A) nutritional enhancement combined with health education, (B) health education alone, (C) nutritional enhancement alone, or (D) standard care (control group). Nutritional support will include individualized diet counseling and oral nutritional supplements tailored to each patient's needs. Health education will be delivered using an "Internet Plus" approach, including weekly educational videos and expert consultations focusing on nutrition, physical activity, and mental health.
The primary objectives are to determine whether these interventions can improve patients' short-term nutritional status and quality of life. Secondary outcomes include the impact of interventions on long-term survival, treatment-related side effects, patient adherence to nutrition recommendations, and psychological well-being.
This study will also investigate the biological mechanisms underlying the clinical effects by analyzing changes in the gut microbiome, blood-based metabolic profiles, and immune responses. Blood, stool, and tumor tissue samples will be collected and analyzed using advanced techniques, including untargeted metabolomics, metagenomics, and single-cell sequencing.
This trial is designed to provide evidence for the integration of nutritional strategies into routine cancer care, and to guide the development of more personalized, effective nutrition-based therapies for colorectal cancer patients. Participants will be followed for up to annually up to 5 years to evaluate both clinical outcomes and biological markers of response.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Eligible participants will be randomized into four parallel arms: (1) individualized nutritional enhancement plus structured health education; (2) structured health education alone; (3) individualized nutritional enhancement alone; and (4) standard care without additional intervention. Personalized nutrition plans will be developed based on energy and protein needs, supported by dietary counseling and the provision of oral nutritional supplements. Health education will be delivered through a digital platform, featuring weekly videos and interactive content on nutrition, exercise, and psychological well-being.
The study includes a 14-day intervention phase and a 12-month follow-up period. Outcomes will be assessed at baseline, and at 1, 2, 3, 6, and 12 months, and annually up to 5 years to evaluate both clinical outcomes and biological markers of response.post-intervention. Key endpoints include improvements in nutritional status, patient-reported quality of life, and overall survival metrics.
To investigate mechanisms, the study incorporates biological sampling and multi-omics analysis. Non-targeted serum metabolomics, gut microbiota metagenomics, and single-cell RNA sequencing of tumor and adjacent normal tissues will be used to characterize metabolic and immune changes associated with the interventions. The study also evaluates the role of inflammatory markers and immune cell profiles in mediating clinical effects.
This trial is expected to generate high-quality evidence supporting the integration of nutrition and health education strategies into standard postoperative care for CRC patients. It may also identify novel metabolic or microbial biomarkers associated with treatment response and prognosis, contributing to the development of precision nutrition approaches in oncology.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Nutritional Enhancement Plus Health Education
Participants in this arm will receive individualized nutritional enhancement along with structured health education. Nutritional intervention includes personalized dietary plans and oral nutritional supplements based on energy and protein requirements. Health education is delivered via an "Internet Plus" platform and includes weekly videos and interactive content focusing on nutrition, physical activity, and psychological support. The intervention lasts for 14 days and is followed by a 12-month, and annually up to 5 years to evaluate both clinical outcomes and biological markers of response. follow-up period.
Personalized Oral Nutritional Supplementation
Participants receive individualized oral nutritional supplementation based on energy and protein requirements, calculated using the Harris-Benedict equation and body weight (1.2-1.5 g protein/kg/day). The supplement may include complete nutrition powder, whey protein powder, and compound multivitamins. The intervention is prescribed and monitored by a clinical nutrition team and adjusted every 3 days during the 14-day intervention phase. The goal is to ensure both energy and protein intake targets are met. Supplements are administered in addition to standard meals.
Personalized Parenteral Nutritional Supplementation
For participants unable to meet nutritional goals through oral intake, parenteral nutrition is administered intravenously. The formulation includes amino acids, glucose, lipids, electrolytes, trace elements, and vitamins. Dosages are aligned with those of the enteral nutrition group, ensuring a consistent intake of energy and protein (1.2-1.5 g/kg/day protein). Formulation and administration follow standardized hospital protocols and are supervised by the nutrition support team.
Structured Nutrition-Focused Health Education
Participants receive structured health education focused on nutrition, physical activity, and psychological well-being. The education is delivered over 14 days using a digital "Internet Plus" platform, featuring weekly videos, interactive Q\&A sessions, and guidance from a multidisciplinary nutrition support team. Educational content covers dietary recommendations, exercise safety, stress management, and post-treatment recovery strategies. Materials are updated weekly, and participants may access them remotely via smartphone or tablet. This intervention aims to improve nutrition knowledge, adherence, and health behavior change.
Health Education Only
Participants in this arm will receive structured health education without additional nutritional supplementation. The education is delivered via an "Internet Plus" platform, including weekly videos and interactive content focused on nutrition knowledge, physical activity guidance, and psychological support. This intervention is administered for 14 days, followed by a 12-month follow-up and annually up to 5 years.
