Study population: Participants in the two BC groups will be recruited from the Massey Cancer Center (MCC) clinical sites in Richmond, VA. Healthy volunteers will be recruited throughout the VCU Health System and through women's groups throughout the greater Richmond, VA area. The PI will provide physicians and clinical nurses an overview of the research and work with them to identify potential project participants. Participants will be provided oral and written information about the research and given an opportunity to ask questions or discuss the project with family or significant others.

Brief summary: This longitudinal project will investigate a common complaint of women who receive chemotherapy for breast cancer- cognitive difficulty. The relationships of fatigue, stress, and depression to cognitive difficulties will be examined. The findings should lead to interventions to decrease the effects of these problematic side effects.

Detailed description: Most women with breast cancer are diagnosed in the early stages of the disease (Stage I and II) and 90% of these can expect to survive at least 5 years. Adjuvant chemotherapy regimens for breast cancer are often associated with complaints of cognitive changes, mostly the inability to concentrate and memory lapses that may persist in some women long after chemotherapy has ended. These changes are frequently accompanied by reports of a triad of behavioral conditions: fatigue, increased stress, and depressive symptoms. Biologically, cytokine release patterns play an important role in regulation of the immune system and normal CNS function, including neural cell repair and metabolism of neurotransmitters-both critical for normal cognitive functioning. Thus, the theoretical underpinnings of this research are embedded in the biobehavioral (mind-body) model which characterizes the multidimensional interactions among the mind, neuroendocrine, and immune systems. The purpose of this prospective, longitudinal project of 100 women is to determine whether there are differences in cognitive functioning and related behavioral conditions (fatigue, perceived stress, and depressive symptoms) in women in each of 3 groups: those with early stage BC treated with surgery and chemotherapy, women with early stage BC treated with surgery and without chemotherapy and an age-gender-education-matched healthy cohort without cancer. The primary aim of the project is to examine the relationships among fatigue, perceived stress, and depressive symptoms and neurocognitive impairment. A secondary aim is to explore the relationships among key behavioral and biological markers that may explain underlying mechanisms for development of neurocognitive impairment. In particular, this project will explore pro- and anti-inflammatory cytokine patterns and their potential associations with neurocognitive functioning. For the primary aim, the mixed linear model will be used to test for differences between the groups. For analysis of the secondary aim variable reduction stage and correlation will be used. The strength of this project is its biobehavioral approach to discerning underlying mechanisms of neurocognitive impairment in women with early stage BC receiving adjuvant chemotherapy. In addition, three other common behavioral conditions associated with BC and/or chemotherapy, fatigue, perceived stress, and depressive symptoms, will be evaluated for their potentially confounding effects on cognitive function.
