Objectives: To evaluate the 5- and 10-year survival prediction of health-related quality of life (HRQoL) scores obtained at diagnosis and at 6, 9 and 12 months after diagnosis in a cohort of curable head and neck squamous cell carcinoma (HNSCC) patients.
Materials and methods: HNSCC patients (n = 109) reported their HRQoL measured by the EORTC Quality of Life Questionnaire (QLQ) general (C30) questionnaire. At diagnosis, the included patients were below 78 years of age and at diagnosis planned treated with curative intent. Clinical variables and self-reported smoking, alcohol consumption and socio-demographic information were registered. From diagnostic blocks, we found 22 patients to be human papillomavirus (HPV) positive. New HRQoL scores were not obtained if the patient treatment changed from curative to palliative throughout the HRQoL data acquisition. Survival was determined from the National Population Register of Norway.
Results: Decreased survival with low HRQoL scores from EORTC QLQ scores was demonstrated with HRQoL scores obtained from different time points of the four time points studied. These survival predictions were mostly independent of HPV status, gender, age, TNM stage, tumor site, alcohol consumption, present smoking status and whether comorbidities were present at diagnosis; as well as to some extent with an adjustment of the same HRQoL score/index obtained at diagnosis. The specific indices "physical function", "general pain" and "sleep disturbance" were in particular predictive of survival.
Conclusion: HRQoL scores obtained throughout the first year after diagnosis contained prognostic power to overall survival when measured both at 5 and 10 years of observation.
