BackgroundCognitive complaints are common amongst breast cancer survivors, and no standard treatment exists. The present study evaluates whether web-based cognitive training can alleviate subjectively reported and objectively assessed cognitive complaints in a sample of breast cancer survivors. The primary and secondary outcomes were an objective measure of working memory and a measure of perceived cognitive functioning. Additional outcomes were neuropsychological tests of memory, executive function, working memory and questionnaire-based assessment of anxiety, depression and somatization. MethodsA total of 157 female breast cancer survivors were recruited from an existing cohort and through announcements in open access cancer-related Internet fora and randomly allocated to either web-based cognitive training (eCogT) with telephone support (n=94) or a waitlist control (WLC) condition (n=63). eCogT encompassed 30 training sessions over 6 weeks. Neuropsychological assessments were undertaken over the telephone, and questionnaire data was collected online. Data was collected at baseline, post-intervention and at 5-month follow-up. ResultsMixed linear models revealed no statistically significant change in primary or secondary outcome at follow-up in either group. Statistically significant improvements (p 0.040-0.043) were found in the eCogT group for verbal learning and on a working memory test. ConclusionsWeb-based cognitive training did not result in improvements of the primary or secondary outcome. Improved performance was observed on verbal learning and working memory. These effects were observed at 5-month follow-up, indicating long-term effects of training. The intervention may be applied in a clinical setting at low cost and without risk of adverse effects.(c) 2016 The Authors Psycho-Oncology Published by John Wiley & Sons Ltd.
