Cognitive impairments in cancer patients represent an important clinical problem. Studies to
date estimating prevalence of difficulties in memory, executive function, and attention

More information is needed on promising biomarkers and allelic variants that may help to
determine the etiology of impairment, identify those most vulnerable to impairment, and
develop interventions for these difficulties.
This is a longitudinal observational study of cognitive function in breast cancer and
lymphoma patients receiving chemotherapy to better understand the prevalence of cognitive
difficulties (i.e., problems with memory, executive function, and attention) in these
