简要总结
This study is a randomized controlled trial aimed at evaluating the effect of a nutritional education program on dietary intake and nutritional status in cancer patients. Patients were randomly assigned to intervention and control groups, with the intervention group receiving structured nutritional education. Participants' nutritional status and daily dietary intake were assessed at baseline and during the follow-up period. The study aims to demonstrate that nutritional education can increase food intake and be effective in improving nutritional status in patients.
详细描述
This study is a randomized controlled trial designed to evaluate the effectiveness of a structured nutritional education program in improving nutritional status in cancer patients. In cancer patients, the disease itself and the treatments administered (chemotherapy, radiotherapy, etc.) increase the risk of malnutrition due to decreased appetite, taste alterations, nausea, vomiting, and metabolic changes. Therefore, nutritional interventions are critically important for clinical outcomes in this group.
Patients included in the study were randomly assigned to intervention and control groups. The intervention group received an individualized and structured nutritional education program. This program included the importance of adequate energy and protein intake, nutritional strategies for symptoms, appropriate food selection, meal planning, and practical nutritional recommendations. The training was supported by both face-to-face sessions and follow-up interviews as needed. The control group continued with routine clinical care.
The nutritional status of the patients was assessed at baseline and at designated follow-up intervals. Clinical nutritional screening tools (such as NRS-2002), anthropometric measurements (body weight, BMI), and food intake records were used to determine nutritional status. Daily energy and protein intakes of the patients were also analyzed.
The primary aim of this study is to determine whether nutritional education increases patients' dietary intake and consequently reduces their risk of malnutrition. The impact of the educational intervention on patients' nutritional awareness, symptom management, and overall eating behaviors is also evaluated.
The results are expected to contribute to the inclusion of nutritional education as a standard intervention in nursing care for oncology patients and to guide clinical practice.

研究组 & 干预措施
Experimental Group
Participants in the experimental group received a structured and individualized nutrition education program in addition to routine clinical care. The intervention was delivered by a trained healthcare professional and focused on improving dietary intake and nutritional status in cancer patients. The program included education on adequate energy and protein intake, management of treatment-related symptoms affecting nutrition (such as nausea, anorexia, and taste changes), appropriate food selection, meal planning strategies, and practical dietary recommendations tailored to individual needs. The education was provided through face-to-face sessions with follow-up reinforcement sessions during the study period.
干预措施: Nutrition Education Program (Other)
Control Group
Participants in the control group received routine clinical care only during the study period. No structured nutrition education or additional dietary counseling was provided beyond standard hospital practices. Patients continued their usual follow-up and medical care as determined by their treating healthcare team. Nutritional status and dietary intake assessments were performed at the same time points as in the experimental group for comparison purposes.

Patient Information Form
时间窗: First Day
The Patient Information Form was developed by the researchers in accordance with the relevant literature. It included items related to patients' sociodemographic and clinical characteristics, such as age, gender, educational status, presence and site of metastasis, number of chemotherapy cycles administered at the time of enrollment, chemotherapy schedule, chemotherapy regimen, and type of chemotherapy (adjuvant or neoadjuvant).
Subjective Global Assessment
时间窗: First day
The SGA is a nutritional assessment tool, which has been shown to demonstrate a strong correlation between subjective clinical judgment and objective nutritional measures. Due to its simplicity and predictive validity comparable to objective methods, it is widely used in clinical practice. The SGA includes components such as medical history (weight change over the past six months, dietary intake changes, gastrointestinal symptoms such as anorexia, nausea, vomiting, and diarrhea), as well as functional capacity. Physical examination findings assess subcutaneous fat loss, muscle wasting, and edema, each scored as 0 (normal), 1+ (mild), 2+ (moderate), or 3+ (severe).

Nutritional Risk Screening
时间窗: The First day
The NRS-2002 aims to identify malnutrition and the risk of malnutrition, and to determine patients who may benefit from nutritional support. The scoring system consists of two sections: 'nutritional status' and 'disease severity,' and allows for scoring as 'no problem,' 'mild,' 'moderate,' and 'severe.' Each section is scored from 0 to 3. In patients over seventy years of age, an additional 1 point is added to the score due to age. Patients with a total score ≥3 are considered to be at nutritional risk.
