abstract = {Breast cancer is the most common form of cancer in women. A
considerable number of women with breast cancer who have
been treated with chemotherapy subsequently develop
neurological symptoms such as concentration and memory
difficulties (also known as 'chemobrain'). Currently, there
are no validated therapeutic approaches available to treat
these symptoms. Cognitive training holds the potential to
counteract cognitive impairment. Combining cognitive
training with concurrent transcranial direct current
stimulation (tDCS) could enhance and maintain the effects of
this training, potentially providing a new approach to treat
post-chemotherapy subjective cognitive impairment (PCSCI).
With this study, we aim to investigate the effects of
multi-session tDCS over the left dorsolateral prefrontal
cortex in combination with cognitive training on cognition
and quality of life in women with PCSCI.The Neuromod-PCSCI
trial is a monocentric, randomised, double-blind,
placebo-controlled study. Fifty-two women with PCSCI after
breast cancer therapy will receive a 3-week tDCS-assisted
cognitive training with anodal tDCS over the left
dorsolateral prefrontal cortex (target intervention),
compared with cognitive training plus sham tDCS (control
intervention). Cognitive training will consist of a letter
updating task. Primary outcome will be the performance in an
untrained task (n-back task) after training. In addition,
feasibility, safety and tolerability, as well as quality of
life and performance in additional untrained tasks will be
investigated. A follow-up visit will be performed 1 month
after intervention to assess possible long-term effects. In
an exploratory approach, structural and functional MRI will
be acquired before the intervention and at post-intervention
to identify possible neural predictors for successful
intervention.Ethical approval was granted by the ethics
committee of the University Medicine Greifswald (BB236/20).
Results will be available through publications in
peer-reviewed journals and presentations at national and
international conferences.ClinicalTrials.gov; NCT04817566,
