The effectiveness of a saline mouth rinse regimen and education programme on radiation-induced oral mucositis and quality of life in oral cavity cancer patients: A randomised controlled trial.

ABSTRACT

Radiation therapy (RT) and concurrent chemotherapy RT (CCRT) generate radiation-induced oral mucositis (OM) and lower quality of life (QOL). This study assessed the impact of a saline mouth rinse regimen and education programme on radiation-induced OM symptoms, and QOL in oral cavity cancer (OCC) patients receiving RT or CCRT. Ninety-one OCC patients were randomly divided into a group that received saline mouth rinses and an education programme and a control group that received standard care. OM symptoms and QOL were assessed with the WHO Oral Toxicity Scale, MSS-moo and UW-QOL. Data were collected at the first postoperative visit to the radiation department (T0) and at 4 weeks and 8 weeks after beginning RT or CCRT. Patients in both groups had significantly higher levels of physical and social-emotional QOL at 8 weeks after beginning RT or CCRT compared to the first visit. Patients in the saline rinse group had significantly better physical and social-emotional QOL as compared to the standard care group at 8 weeks. Radiation-induced OM symptoms and overall QOL were not different between the groups. We thus conclude the saline rinse and education programme promote better physical and social-emotional QOL in OCC patients receiving RT/CCRT.
