Psychological variables associated with quality of life following primary treatment for head and neck cancer: a systematic review of the literature from 2004 to 2015

Several psychological factors predict QoL among HNC survivors who have completed treatment. Routine screening and early interventions that target distress could improve HNC survivors' QoL following treatment. Longitudinal and population-based studies incorporating more systematic and standardised measurement approaches are needed to better understand relationships between psychological factors and QoL and to inform the development of intervention and supportive care strategies.
