Head and Neck Cancer: A Study on the Complex Relationship between QoL and Swallowing Function

Area of Science:

• Oncology
• Otolaryngology
• Speech-Language Pathology
• Quality of Life Research

Background:

• Head and neck squamous cell carcinoma (HNSCC) significantly impacts patient survival and function.
• Post-treatment sequelae like dysphagia are common, affecting Quality of Life (QoL).
• Existing QoL measures often lack objective correlates, potentially misrepresenting patient outcomes.

Purpose of the Study:

• To investigate the relationship between subjective QoL measures (EQ-5D-5L, MDADI) and objective swallowing function (FEES) in HNSCC patients.
• To determine the utility of swallowing-specific versus generic QoL in reflecting disease severity and treatment impact.

Main Methods:

• Cross-sectional study evaluating HNSCC patients.
• Subjective QoL assessed using EQ-5D-5L and MD Anderson Dysphagia Inventory (MDADI).
• Objective swallowing function evaluated via Fiberoptic Endoscopic Evaluation of Swallowing (FEES), including Penetration-Aspiration Scale (PAS) and residue assessment.

Main Results:

• Significant discordance observed between objective swallowing metrics (PAS, residue) and subjective QoL scores (p=0.21).
• MDADI scores correlated with tumor stage, multimodal therapy, and feeding tube dependence, unlike generic QoL.
• Observed MDADI score differences were <10 points, limiting clinical significance despite statistical correlation.

Conclusions:

• QoL questionnaires alone are insufficient for comprehensive assessment in HNSCC due to reliance on patient perception.
• Objective swallowing evaluations are crucial to detect impairments like silent aspiration missed by subjective reports.
• Integrating subjective QoL with objective functional data is essential for holistic patient care and research in HNSCC survivorship.
