A pilot study using pre-treatment physical activity level to predict long-term health-related quality of life in patients with head and neck cancer.

Abstract

Pre-treatment levels of physical activity (PA) in head and neck cancer (HNC) are rarely evaluated using accelerometry. This study aimed to investigate whether pre-treatment PA level in HNC predicts aspects of long-term health-related quality of life (HRQL) at 12 months after end of treatment. This pilot study included 48 patients diagnosed with HNC, 41 participants remaining at 12 months post-treatment. Pre-treatment PA was objectively assessed by an accelerometer. Self-perceived PA and HRQL were assessed pre-treatment and at 6- and 12-months post-treatment. Patients with a higher pre-treatment PA level scored higher on physical function and role function and less fatigue and pain at the 12 months follow-up compared to patients with a lower pre-treatment PA. At 6 months the groups differed only on physical functioning. When comparing changes over time, there were statistically significant differences comparing high and low pre-treatment PA in the fatigue and pain domains between 6 and 12 months. Exploratory multiple regression analyses also indicated that higher pre-treatment PA levels were associated with greater favorable change in the four HRQL measures. Higher levels of PA assessed with accelerometer before oncologic treatment associated favorably with aspects of self-perceived HRQL and PA over time in patients with HNC.
