Overview
Brief Summary
This multicenter, prospective cohort study investigates the long-term impact of nutritional status on clinical outcomes in cancer patients undergoing treatment in Shaanxi Province, China. It evaluates how malnutrition, dietary patterns, and nutritional interventions affect treatment tolerance, quality of life, and survival. The study tracks dynamic changes in nutritional health and related indicators throughout various stages of chemoradiotherapy, aiming to inform evidence-based strategies for precision nutrition in oncology care.
Detailed Description
Study Purpose and Objectives: The Nutritional Status and Clinical Outcomes in Patients with Common Malignancies (NCOM) study aims to assess how nutritional status influences treatment-related complications, functional performance, psychosocial well-being, and long-term survival in cancer patients. By capturing longitudinal data, the study seeks to identify modifiable risk factors and develop predictive models to support personalized nutritional interventions in oncology. Study Design and Scope: The study is being conducted at 11 tertiary hospitals across Xi'an, Shaanxi Province, and will recruit a total of 1,538 patients diagnosed with common malignancies. Participants are enrolled within 48 hours of hospital admission and followed at structured intervals over a five-year period: at 1, 2, 3, 6, and 12 months, and then annually. Baseline and follow-up evaluations include demographic data, cancer-specific clinical characteristics, nutritional risk (mPG-SGA, NRS-2002), dietary intake (SDSAT), quality of life (EORTC QLQ-C30), psychosocial health (HADS), physical activity, sleep quality (PSQI), and laboratory biomarkers. Data Collection and Management: Standardized procedures are used for anthropometric measurements, clinical assessments, and patient-reported outcomes. Nutritional support in and out of hospital, inflammatory biomarkers, liver and kidney function, and hematological indicators are systematically recorded. All data are managed via REDCap with built-in validation, routine audits, and centralized oversight. Quality Assurance and Training: Research personnel at each site undergo rigorous training to ensure consistency in data collection and patient evaluation. Supervisors oversee data quality, coordinate follow-up, and address missing data or protocol deviations. Ethical Oversight: The study adheres to the Declaration of Helsinki and was approved by the Ethics Committee of Xi'an Jiaotong University Health Science Center (Approval No. 2022-1373). Written informed consent is obtained from all participants. All personal data are deidentified and securely stored. Expected Outcomes and Significance: By establishing the temporal relationships between nutritional status and clinical outcomes, the NCOM study will provide high-quality evidence to support individualized nutrition-focused care. Results are expected to improve early identification of patients at risk, optimize nutritional interventions, reduce treatment-related toxicity, and enhance long-term cancer prognosis.

Outcomes
Primary Outcomes
Change in Nutritional Status Assessed by Modified Patient-Generated Subjective Global Assessment (mPG-SGA)
Time Frame: Baseline, 1, 2, 3, 6, and 12 months after admission; annually up to 5 years
Longitudinal assessment of nutritional status using the mPG-SGA, a validated tool composed of five sections (weight loss history, dietary intake, symptoms, function/activity, and age). Total scores range from 0 to ≥7 points, with higher scores indicating worse nutritional status. Patients will be classified as: 0-2 = Normal 3-6 = Mild malnutrition ≥7 = Moderate to severe malnutrition.
Change in Nutritional Risk Assessed by Nutritional Risk Screening 2002 (NRS-2002)
Time Frame: Baseline, 1, 2, 3, 6, and 12 months after admission; annually up to 5 years
Longitudinal evaluation of nutritional risk using the NRS-2002, which considers disease severity, nutritional impairment, and age. Total score ranges from 0 to ≥7 points. A score of ≥3 indicates nutritional risk and warrants intervention; \<3 indicates no immediate risk.
Change in Global Health Status Score on the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30)
Time Frame: Baseline, 1, 2, 3, 6, and 12 months after admission; annually up to 5 years
Assessment of patients' perceived overall health status using the global health subscale of the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30). Scores range from 0 to 100, with higher scores indicating better global quality of life.
Change in Functional Scores on the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30)
Time Frame: Baseline, 1, 2, 3, 6, and 12 months after admission; annually up to 5 years
Evaluation of physical, role, emotional, cognitive, and social functioning domains using the functional scales of the EORTC QLQ-C30. Each domain score ranges from 0 to 100, with higher scores representing better functioning. Each domain will be reported separately.
Change in Symptom Scores on the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30)
Time Frame: Baseline, 1, 2, 3, 6, and 12 months after admission; annually up to 5 years
Assessment of symptom burden including fatigue, pain, nausea/vomiting, appetite loss, sleep disturbance, constipation, diarrhea, and financial difficulty using symptom subscales of the EORTC QLQ-C30. Each symptom is scored separately from 0 to 100, with higher scores indicating worse symptom severity.
Overall Survival (OS) in Cancer Patients
Time Frame: From date of enrollment until death or last follow-up (up to 5 years)
Overall survival is defined as the time from the date of enrollment to the date of death from any cause. Patients still alive at the last follow-up will be censored. Kaplan-Meier survival analysis and Cox proportional hazards regression will be used to estimate survival and explore associations with baseline and longitudinal nutritional status.
Progression-Free Survival (PFS) in Cancer Patients
Time Frame: From date of enrollment until death or last follow-up (up to 5 years)
Progression-free survival is defined as the time from enrollment to the first documented disease progression or death from any cause, whichever occurs first. Patients without progression at the time of last follow-up will be censored. PFS will be analyzed using Kaplan-Meier estimates and Cox regression models, stratified by nutritional status.
