Radiation therapy (RT) leads to a markedly reduced salivary secretion rate, which makes it difficult to eat and talk and it is a risk factor for oral disorders such as caries and mucosal infections. A reduced salivary secretion rate is often a life long side-effect of the treatment that seriously affect the quality of life. To reduce these side-effects the patients get preventive and supportive oral treatment in connection with their cancer treatment. However, regardless of radiation doses given, the severity of the problems vary considerably. Therefore, a better understanding on when and why problems occur is important for the identification of subjects at risk and to find better measures and treatments, suited for their individual needs.
Dentate subjects were included referred before RT. Data were collected before and during treatment as well as 6, 12 and 24 months after completed RT. Cancer diagnosis, treatment, radiation doses, infections and medication were obtained from medical records.
Dietary habits were registered using a questionnaire focusing on intake of carbohydrate-rich food-items and items containing sugar-substitutes. The subjects weight was registered before, during and after RT.
A clinical examination was performed before and 6, 12 and 24 months after completed RT. Panoramic x-rays were taken as well as bitewing radiographs. The number of teeth, caries status, oral hygiene were registered. Mucositis was registered during RT.
Secretion of stimulated whole saliva was determined. Minor labial and buccal gland saliva secretion rate was determined using the Periotron-method. Microbial samples were collected from the tongue, buccal mucosa and supragingival plaque and microorganisms associated with oral health and oral disorders analysed using cultivation technique.
The quality of life was registered using the questionnaires EORTC QLQ-C30 (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire). To address additional symptoms associated specifically with cancer in the head and neck region and its treatment, a complementary 35-item module, the EORTC QLQ-H&N35 was used.
The patients also completed the Hospital Anxiety and Depression Scales, HADS, which is used to measure severity of anxiety and depressive symptoms and provides estimates of possible mood disorders in patients with somatic comorbidity.
