Detailed Description
Adjuvant aromatase inhibitor (AI) therapy improves disease-free and overall survival for postmenopausal women after surgery for hormone receptor-positive breast cancer. Among symptoms associated with AI therapy are changes in cognitive function. Up to 25% of postmenopausal women with breast cancer report that they experience changes in cognitive function during AI therapy. Studies using neuropsychological tests found subtle deteriorations in verbal and visual learning and memory-as well as concentration, working memory, and executive function-for as many as a third of these patients. Changes in cognitive function may be associated with changes in affect (e.g., worry, depressive symptoms). Neural markers of cognitive changes, including changes in brain function and structure, may underlie changes in cognitive function.
The investigators' recent preliminary neuroimaging work to describe neural markers of cognitive changes suggests that postmenopausal women with breast cancer have inefficient cognitive-emotion processing before AI therapy, as evidenced by greater neural activity in the hippocampus (working memory) and amygdala (emotion processing) during task performance compared to controls. During AI therapy, patients show differential activation compared to controls in the dorsolateral prefrontal cortex (executive function and working memory), medial prefrontal cortices (cortical control of amygdala responses), and hippocampus.
Stress responses could partially explain relationships between AI therapy and neural markers of cognitive changes. The Mindfulness Stress-Buffering Account suggests that interventions such as Mindfulness-Based Stress Reduction (MBSR) may improve stress responses by attenuating negative appraisals of stress and reducing reactivity to stressful situations. For example, mindfulness meditation improved psychological stress responses in women with breast cancer. It improved some measures of cognitive function. Mindfulness practices reduced physiological markers of stress responses, including inflammatory markers in women with breast cancer and in stressed community adults, as well as cortisol reactivity for breast cancer survivors and during chemotherapy for colorectal cancer. Although similar neural deficits as were found in the investigators' preliminary work have been shown to improve in stressed adult populations using MBSR, it is not known whether the intervention improves neural deficits in women taking AI therapy (estrogen, production of which is blocked by AI therapy, is neuroprotective and promotes neural plasticity). Genetic variability was previously found to moderate the effect of MBSR on self-reported cognitive function. Therefore, it is possible that inter-individual variability in the expression of genes involved in stress responses could moderate relationships between AI therapy and neural markers of cognitive changes during MBSR. Taken together, MBSR may improve neural markers of cognitive changes shown in preliminary work to be deficient in postmenopausal women before and during AI therapy for breast cancer by targeting stress responses. Changes in these neural markers may correspond to improved self-report and neuropsychological measures of cognitive function.
Hypothesis: Stress reduction, moderated by gene expression, blunts the impact of AI therapy on neural markers of cognitive function, thereby improving cognitive function and affect in women with breast cancer.

MRI-incompatible metal implant*
- If a potential participant reports implanted metal objects, which might be affected by MRI magnets, the study personnel and MRI technologist will screen over the phone or in person to determine whether the potential participant would be safe during the MRI scan. A current list of implants compatible with MRI will be consulted (http://www.mrisafety.com/TMDL_list.php).

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: MBSR
Mindfulness-Based Stress Reduction
|
The MBSR group will receive training from a certified instructor during a group-based, 2.5-hour manualized educational activity weekly for eight weeks.
Activities include body scans, gentle stretching, yoga, and mindful awareness.
Participants will be asked to complete daily 45-minute, audio-guided mindfulness activities and a one-day weekend retreat to reinforce learning.

Active Comparator: Health Enhancement Program
|
The HEP control, which was developed to serve as an active control to MBSR, will receive manualized health education from experts in physical activity, functional movement, music therapy, and nutrition-without mindfulness instruction-using similar modalities to MBSR training for a matched schedule.
