History of Changes
  Purpose

The purpose of this study is to learn more about how chemotherapy affects an individual's thinking abilities (cognition). Some research has shown that chemotherapy can cause changes in cognition in breast cancer survivors. However, it is not clear why this change occurs. In this study, the investigators will look to see if damage to DNA is related to these changes in cognition. Specifically, the investigators want to see 1) if women who have been treated with chemotherapy have more DNA damage than healthy women; and 2) if DNA damage is related to cognitive problems in breast cancer survivors and healthy women.

Groups/Cohorts Assigned Interventions
1
Breast cancer survivors (2-6 years post-treatment) who were post-menopausal at the time of diagnosis and treated with a combination of chemotherapy and hormonal therapy, matched on age and education
 Behavioral: Mini-Mental State Exam and Blood draw
The neuropsychological testing will be conducted by a psychometrician who will be trained and supervised by Dr. Correa. It should take approximately 2 hours to complete.Two blood samples will be collected in green top tubes for analysis of DNA damage

Breast cancer survivors (2-6 years post-treatment) who were post-menopausal at the time of diagnosis and treated with hormonal therapy only matched on age and education
 Behavioral: Mini-Mental State Exam and Blood Draw
The neuropsychological testing will be conducted by a psychometrician who will be trained and supervised by Dr. Correa. It should take approximately 2 hours to complete.Two blood samples will be collected in green top tubes for analysis of DNA damage
3
Healthy women matched on age and education

Detailed Description:

The primary objective of this proposal is to obtain preliminary data regarding the association between DNA damage and cognitive functioning in breast cancer survivors. Specifically, we predict that:

  1. Breast cancer survivors treated with chemotherapy and hormonal therapy will have higher levels of DNA damage as measured by the Comet assay as compared to age and education matched survivors treated with hormonal therapy only and healthy controls.
  2. Survivors who meet criteria for cognitive impairment will have higher levels of DNA damage as compared to cancer survivors who do not meet criteria for cognitive impairment and healthy controls.

Criteria

Inclusion Criteria:

  • Breast cancer survivors (Stage I-III) 2-6 years post all cancer treatments, but currently receiving hormone therapy.
