Key Takeaway
Consider nutritional prehabilitation may benefit head and neck cancer patients, but evidence quality needs improvement.

This is an evidence mapping review that synthesized 6 systematic evaluations, 13 randomized controlled trials, and 4 observational studies on pretreatment nutritional prehabilitation for patients with head and neck cancer. The scope included interventions such as immunonutrition, nutritional risk screening, enteral support, counseling, and swallow training.

The authors synthesized findings that nutritional prehabilitation benefits prognosis, improves nutritional status, and enhances quality of life. The review reports beneficial effects across outcomes including nutritional status, complication rates, length of hospital stay, body weight, BMI, prognosis, and quality of life. No pooled effect sizes or quantitative syntheses were reported.

Key limitations noted by the authors are that the methodological quality of the included studies needs to be improved and more high-quality, large-sample clinical studies should be conducted in the future. Safety data were not reported.

The authors suggest the review provides a basis for clinical practice and may guide implementation of nutritional prehabilitation. Practice relevance is framed cautiously given the evidence limitations.

Patients with head and neck cancer often face a tough battle. Their bodies struggle to keep up with the demands of treatment. A new look at the evidence suggests that preparing the body before surgery or radiation can make a real difference. This preparation, called nutritional prehabilitation, includes things like nutritional counseling, specific diet formulas, and swallow training. The goal is to get patients in the best possible shape before they start their main treatment.

The review examined multiple studies to see if this preparation helped. The findings are clear. Patients who received this extra care had better nutritional status. They also experienced fewer complications and spent less time in the hospital. Their body weight and BMI improved, and their overall quality of life was higher. Essentially, getting ready beforehand helps them survive and recover better.

However, the current evidence has some gaps. The quality of the studies included in this review needs to be improved. More high-quality, large-scale clinical studies should be conducted in the future to confirm these results. Until then, this analysis provides a solid basis for clinical practice. It guides doctors on how to implement nutritional prehabilitation for their patients. The message is simple: do not wait until a patient is too weak to help them. Start the preparation early.

What this means for you:
Nutritional prehabilitation improves outcomes and quality of life for head and neck cancer patients.

BACKGROUND: Head and neck cancer patients are often at high risk of malnutrition due to the disease and its treatment, and pretreatment nutritional prehabilitation is an important strategy for improving prognosis; however, the existing evidence still needs to be systematically synthesized. PURPOSE: To systematically describe and evaluate the evidence related to pretreatment nutritional prehabilitation in patients with head and neck cancer through evidence mapping to provide a basis for clinical practice. METHODS: Computerized searches of CNKI, Wan-fang, VIP, SinoMed, PubMed, Web of Science, Cochrane Library, Embase, and CINAHL were performed from the time of database construction to May 2025, to include systematic review/meta-analysis of nutritional prehabilitation of patients with head and neck cancer, randomized controlled trials, and observational studies. The Risk of Bias Tool, Newcastle-Ottawa Scale (NOS), and AMSTAR-2 scale were used to evaluate the methodological quality of the included studies, respectively, and the current status of the studies was demonstrated using a combination of text and graphs. RESULT: Then, 6 systematic evaluations/meta-analyses, 13 randomized controlled trials, and 4 observational studies were finally included. The largest number of studies was published in China, and all study populations consisted exclusively of patients with head and neck cancer. Interventions include pretreatment immunonutritional interventions, nutritional risk screening-guided interventions, standard enteral nutritional support, disease-specific nutritional formula support, nutritional counseling, and pretreatment swallow training. The outcome indicators mainly focused on the patients' nutritional status, complication rates, length of hospital stay, body weight, and BMI, etc. However, the methodological quality of the included studies needs to be improved. The results of the studies all showed that nutritional prehabilitation benefits the prognosis of patients with head and neck cancer. CONCLUSION: Overall evidence suggests that nutritional prehabilitation can improve patients' nutritional status and enhance their prognosis and quality of life, showing beneficial effects. More high-quality, large-sample clinical studies should be conducted in the future to guide the clinical implementation of nutritional prehabilitation.
