BACKGROUND: Childhood cancer survivors may have experienced a high number of invasive medical and dental procedures which are known to be risk factors for dental anxiety. AIM: The aim of this study was to examine the prevalence of dental anxiety among children who have survived cancer. DESIGN: In a cross-sectional study, we examined 51 6- to 14-year-old children who had been treated for cancer at Aalborg Hospital, and 192 children without cancer. All children answered the Dental Subscale of the Children's Fear Survey Schedule. Dental anxiety was defined as a dental anxiety score exceeding the mean dental anxiety score + 1 standard deviation for the children without cancer. RESULTS: Children with cancer did not have an increased prevalence of dental anxiety compared with children without cancer: the prevalence ratio was 0.41 [95% confidence interval (CI): 0.10-1.24]. The mean dental anxiety score was 23.1 (95% CI: 21.2-25.0) among children who had been treated for cancer, and 24.7 (95% CI: 23.4-26.0) among children without cancer (mean difference: 1.6; 95% CI: 1.1-4.3). CONCLUSION: Cancer and cancer treatment during childhood were not associated with an increased risk of dental anxiety in this population.
Objectives: Knowledge of health related quality of life of haematological patients is limited. This study aimed at investigating the prevalence and predictors of symptoms and problems in a representative sample of haematological patients in Denmark. Methods: A random sample of patients with leukaemia, multiple myeloma and advanced lymphoma (n = 732) received the European Organisation for Research and Treatment of Cancer quality-of-life questionnaire (EORTC QLQ-C30). Mean scores were calculated. In addition, scores were dichotomised using two thresholds: patients reporting at least 'a little' of each EORTC QLQ-C30 symptom/problem were classified as having a 'symptom/problem', and patients reporting at least 'quite a bit' were classified as having a 'severe symptom/problem'. Multiple logistic regression was used to identify predictors. Results: In total, 470 (64%) patients participated. The most frequent symptoms/problems were fatigue (55%; severe 20%), reduced role function (49%; severe 23%), insomnia (46%; severe 15%), and pain (37%; severe 15%). Older patients and patients in active antineoplastic treatment had more symptoms and problems. There was only little evidence of social inequalities. Conclusion: This is probably the first nationally representative study of symptoms and problems in haematological patients. These patients have symptoms/problems that deserve attention. Health related quality of life is an important issue in haematological malignancies.
