Objective:

To assess the associations between pre-treatment nutritional parameters (including PG-SGA, GLIM, WLGS, and cachexia criteria) and clinical outcomes (mortality, local recurrence, and metastasis) over a five-year follow-up in patients with head and neck cancer, and to evaluate the prognostic validity of these nutritional parameters.

Approach:

Key Findings:

• Pre-treatment nutritional status significantly impacts mortality, local recurrence, and metastasis in head and neck cancer patients, with specific statistical correlations.
• Higher nutritional risk scores correlated with worse clinical outcomes.
• The study highlights the importance of comprehensive nutritional assessment in clinical practice, suggesting potential mechanisms for improved outcomes.

Interpretation:

The findings suggest that addressing nutritional risk and malnutrition in head and neck cancer patients may improve clinical outcomes and reduce the incidence of local recurrence and metastasis through targeted nutritional interventions.

Limitations:

• The study was conducted at a single center, which may limit generalizability to broader populations.
• Loss to follow-up reduced the sample size from 91 to 84 participants, potentially biasing the results and affecting the robustness of conclusions drawn.

Conclusion:

Nutritional assessment should be integrated into the management of head and neck cancer patients to potentially enhance survival and reduce recurrence rates.
