Quality of Life and Functional Status Measures in Patients With Head and Neck Cancer

Abstract

OBJECTIVE: To assess the relationship among three validated head and neck-specific measures of functional status and a general measure of quality of life in patients with head and neck cancer. DESIGNS: Cross-sectional study using medical chart review, patient interview, and test administration. SETTING: Academic tertiary referral center. PARTICIPANTS: Fifty adults patients 3 months to 6 years after major surgery for head and neck cancer. MAIN OUTCOME MEASURE: Scores from a general measure of quality of life (the Functional Assessment of Cancer Therapy), a subscale specific to head and neck cancer, the University of Washington Quality of Life Questionnaire, and the Performance Status Scale for Head and Neck Cancer Patients. RESULTS: The disease-specific measures of functional status correlate well with one another. However, there were low correlations between the Functional Assessment of Cancer Therapy and the disease-specific measures, indicating that general and disease-specific instruments contribute unique information about quality of life. CONCLUSION: A general measure of quality of life augments information obtained by disease-specific instruments by interpreting functional status in the broader scope of the patient's life.
