About

RATIONALE: Breast cancer and its treatment may cause changes in a patient's ability to think, learn, and remember. Gathering information about a woman's genes, brain function, and personal history may help doctors learn more about the disease and plan the best treatment.

PURPOSE:

1. To determine changes in brain function that occur following breast cancer chemotherapy.
2. To gain further understanding of the individual differences in brain function changes and recovery based on demographic, medical and treatment variables.

Full description

This study aims to determine some of the genetic, neurobiologic and demographic factors that are associated with cognitive outcome following breast cancer (BC). Additionally, it aims to test novel behavioral interventions designed to improve executive function skills following BC treatment.

Enrollment: 50 patients

Sex: Female

Ages: 40 to 65 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

3.1.1 Primary, non-metastatic breast cancer

3.1.2 Newly diagnosed patients who have not yet begun treatment.

3.1.4 Female participants age 40-65 years of all ethnicities who speak fluent English will be recruited.

3.1.5 There are no life expectancy restrictions.

3.1.6 Karnofsky Performance Status 70% minimum. ECOG will not be employed.

3.1.7 There are no requirements for marrow function. The brain must be free from gross neuropathology and metastases in order to participate.

3.1.8 Ability to understand and the willingness to sign a written informed consent document.

Exclusion criteria

3.2.1 History of cognitive, psychiatric or medical conditions prior or unrelated to cancer diagnosis and/or known to significantly impact assessments (e.g. premature birth, developmental delays, learning disabilities, severe psychiatric conditions, brain injury, stroke). Non-English speaking. Major sensory impairment (e.g. hearing loss, blindness) that would render assessments invalid. MRI contraindications (e.g. metallic implants or devices). Distant metastases. See also section 4.2.1.

3.2.2 Participants currently involved in studies specifically aimed at improving cognitive symptoms will be excluded.

3.2.3 Participants with significant co-morbid diseases known to significant impact neuropsychological function such as Alzheimer's or Parkinson's will be excluded.

3.2.4 There are no known risks for allergic reactions to any of the study procedures.

3.2.5 Participants taking certain medications that affect neuropsychological and/or brain function including Haldol, Aricept, Ritalin, etc. will be excluded. Most anti-depressants are acceptable. Some anti-anxiety medications may not be. Each case will be individually reviewed.

3.2.6 There are no other agent-specific exclusion criteria.

3.2.7 Pregnant individuals will be excluded as this is a contraindication for the 3 Tesla research MRI scanner employed by this study but not because of the treatment programs per se. Nursing individuals can enroll.

3.2.8 Patients who are HIV positive will be excluded given the known effects of this condition on cognitive function which would confound the effects of anti-cancer treatments on cognitive outcome.

50 participants in 3 patient groups

Cognitive Rehabilitation (Breast Cancer(BC) with chemotherapy)

Active Comparator group

Description:

Cognitive rehabilitation is a very low-risk method of treatment for cognitive deficits that involves restoring impaired function and/or training the individual to compensate for the area of deficit. Subjects will complete a curriculum of cognitive exercises 30 minutes per day, 5 days per week for 6-weeks.

Treatment:

Behavioral: Cognitive Rehabilitation

Active Neurofeedback (BC pre-chemotherapy)

Active Comparator group

Description:

In active Neurofeedback session subjects will be trained to increase brain activation in regions associated with executive function (EF) function deficits (as determined by neuroimaging measures) by viewing their own brain activation in real-time. The "dose" will be 2-3 sessions, each lasting approximately 30 minutes.

Treatment:

Behavioral: Active Neurofeedback Training

Neurofeedback placebo (Sham) (BC pre-chemotherapy)

Sham Comparator group

Description:

Neurofeedback training: 2-3, 30 min training sessions. For the sham placebo group, fabricated real-time data will be provided to the subject as feedback information hence enabling the subject to view information identical to experimental subjects but without accurate data pertaining to their own brain activation. The technician will be blinded to the subject's treatment condition assignment.

Treatment:

Behavioral: Neurofeedback Training (placebo / Sham)
