          Abstract

          The aim of this study was to review the published literature addressing the question of whether intensity-modulated radiotherapy (IMRT) resulted in an improvement of quality of life (QoL), especially xerostomia-related QoL of all nasopharyngeal carcinoma patients as time progressed. A literature search of PubMed, Embase and Google Scholar was performed, only reports containing original data of the QoL scores after treated by IMRT were included. Two independent reviewers extracted information of study design, study population, interventions, outcome measures and conclusions for each article. The inclusion criteria were met by 14 articles covering outcomes based on the questionnaires treated by IMRT. Data from same questionnaires (European Organization of Research and Treatment of Cancer QLQ-C30 and H&N35 questionnaires) were exacted and we analyzed four items (global health status, dry mouth and sticky saliva, swallowing, social eating and social contact), which have a close relationship with xerostomia-related QoL. Results indicated that a maximal deterioration of most QoL scales including global health status developed during treatment or at the end of the treatment course and then followed by a gradual recovery to 1 year, 1-2 years after IMRT, compared with their baseline level, some specific head and neck items, most in the EORTC QLQ H&N35, remained worse for the surviving patients. In conclusion, the published data reasonably support the benefits of IMRT in improving QoL, but xerostomia-related items still had a significantly negative effect in 2 years to impact a survivor's QoL.
