Changes in quality of life of head-and-neck cancer patients following postoperative radiotherapy.

The purpose of this study was to investigate the longitudinal changes in quality of life (QoL) for 77 head-and-neck squamous cell cancer (HNSCC) patients receiving postoperative radiotherapy (RT). The data pertaining to their QoL were collected using the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire (EORTC QLQ-C30) and the EORTC Head and Neck Module (QLQ-H&N35) before and two years after postoperative RT. The differences in all the QLQ-C30 scales between the two time points were not statistically (p<0.01) or clinically (difference > or =+10 points) significant. Of all the scales in the QLQ-H&N35, only problems in social eating, teeth, dry mouth, and sticky saliva became worse with both statistical and clinical significance. Clinical cancer stage and marital status were the only variables significantly associated with the change in global QoL. The subjects with stage IV disease (5.0-fold) and those with a spouse (5.5-fold) had a lower risk of reporting negative changes in global QoL. The study indicates that some individual HNSCC patients, after receiving postoperative RT, suffered from a deterioration of QoL scales, especially in some specific head-and-neck symptoms. Meanwhile, we found some patients, especially those with more advanced HNSCC, might have developed somewhat tougher coping abilities to deal with the adverse effects of adjuvant RT on their global QoL.
