A prospective study on quality of life of patients with cancer of the oral cavity or oropharynx treated with surgery with or without radiotherapy.

The aim of this study was to describe prospectively quality of life and mood in patients with oral or oropharyngeal cancer treated with surgery +/- radiotherapy. Seventy-five patients completed the EORTC Core Questionnaire, the EORTC Head and Neck Cancer module and the Center for Epidemiologic Studies' Depression Scale before treatment and 6 and 12 months later. There was a significant deterioration of physical functioning, fatigue and almost all head and neck symptoms except pain, which improved. Patients with stage III/IV and patients receiving combined treatment had significantly worse physical symptoms compared to patients with stage I/II and patients treated with surgery only, respectively. Before and after treatment there was a high level of depressive symptomatology. However, after treatment a gradual improvement in emotional functioning occurred. Surgical treatment for oral or oropharyngeal cancer results in significant deterioration of physical functioning and symptoms during the first year, especially when combined with radiotherapy. Despite this, there is an improvement of emotional functioning after treatment, probably as a result of adaptation and coping processes.
