Telephone Support for Metastatic Breast Cancer Patients

This trial tests telephone-based Acceptance and Commitment Therapy (ACT), a type of psychotherapy, to reduce fatigue interference with activities, mood, and cognition in metastatic breast cancer (MBC) cancer patients. ACT includes mindfulness exercises (e.g., meditations, performing activities with greater awareness), identifying personal values (e.g., family, work), and engaging in activities consistent with these values. A total of 250 patients will be randomly assigned in equal numbers to either the ACT intervention or an education/support condition. Patients in both conditions will participate in six weekly 50-minute telephone sessions. Outcomes will be assessed at baseline, 2 weeks post-intervention, and 3 and 6 months post-intervention. The investigators hypothesize that ACT will lead to improved primary and secondary outcomes as compared to education/support. A demonstration of ACT's efficacy will lead to dissemination of the intervention and ultimately fulfill an unmet need in the comprehensive care of MBC patients.

About this study

This trial tests the effect of telephone-based Acceptance and Commitment Therapy (ACT) on fatigue interference in metastatic breast cancer (MBC) patients (Aim 1) as well as secondary outcomes (Aim 2). This trial also examines increases in psychological flexibility as a hypothesized mediator of ACT's effect on fatigue interference (Aim 3). Finally, two core aspects of psychological flexibility (i.e., mindfulness/acceptance and commitment/behavior change processes) are examined as exploratory mediators of ACT's effect on fatigue interference. The study team will recruit MBC patients receiving care through Eskenazi Health or Indiana University (IU) Health. Potentially eligible patients will be mailed an introductory letter signed by their oncologist and the PI along with a consent form. The letter will have a number to call if they do not wish to be contacted further. A research assistant (RA) will call all prospective participants who do not opt out approximately 1 to 2 weeks after the letter is mailed. The RA will describe the study as outlined in the consent form and answer any questions. Then the RA will administer an eligibility screening to those who consent to participate. Eligible and consenting patients will complete a 35-minute baseline phone assessment. Following baseline assessments, MBC patients (N = 250) will be randomly assigned in equal numbers to ACT or education/support using a stratified block randomization scheme to balance the groups by age (<65 yrs. vs. 65+ yrs.) and performance status (patient-reported Eastern Cooperative Oncology Group [ECOG] scores 0 or 1 vs. 2). Patients in both study conditions will complete six weekly 50-minute telephone sessions with the first session occurring one week after baseline. For ACT participants, adherence to home practice during the past week will be assessed and recorded during each session. Blind interviewers will assess outcomes and potential mediators during 30-minute follow-up phone assessments at 2 weeks, 3 months, and 6 months post-intervention.

Treatment and study plan

Acceptance and Commitment Therapy

Behavioral

Across six weekly 50-minute sessions, patients in the Acceptance and Commitment Therapy condition will practice various mindfulness exercises, clarify their values, and set specific goals consistent with their values. Sessions will incorporate discussion of patients' cancer experiences. Through in-session and home practice of skills, participants will learn new and more adaptive ways to respond to fatigue. Participants will receive handouts on session topics and a compact disc (CD) that we developed to guide mindfulness practices.

Education/Support

Behavioral

Across six weekly 50-minute sessions, patients in the education/support condition will discuss their concerns, including symptoms and other cancer-related stressors, with a therapist providing psychological support. The therapist will direct patients to resources for practical and health information and contact information for psychosocial services. Sessions will include an orientation to the patient's medical center, education regarding common cancer-related symptoms and quality-of-life concerns, and an overview of resources for addressing these concerns. The therapist will also describe resources for addressing financial concerns and methods of evaluating health information available via the Internet and other modalities. Participants will receive handouts on session topics and will be asked to review them as homework.

Primary outcomes

  1. Fatigue Interference Subscale of Fatigue Symptom Inventory

    Time frame: 2 weeks, 3 months, and 6 months post-intervention

    Seven items are rated on 11-point scales (0=no interference to 10=extreme interference) that assess the extent to which fatigue in the past week interfered with general level of activity, ability to bathe and dress, normal work activity (including housework), ability to concentrate, relations with others, enjoyment of life, and mood. The seven items are summed with higher total scores indicating greater fatigue interference. The total score range is 0 to 70. This is the primary outcome.

Secondary outcomes

  1. Patient Reported Outcomes Measurement Information System (PROMIS) Sleep-related Impairment

    Time frame: 2 weeks, 3 months, and 6 months post-intervention

    This 8-item measure assesses the perceived interference of sleep problems with activities, mood, and cognition (e.g., difficulty concentrating or completing tasks). Each item is rated on a scale from 1 (not at all) to 5 (very much). Item #2 is reverse-scored and then the 8 items are summed with higher total scores indicating greater sleep-related impairment. The total scores are converted to T-scores with a range from 30.0 to 80.1. Higher T-scores indicate a worse outcome. The population mean for T-scores is 50 with a standard deviation of 10. This is a secondary outcome.

  2. PROMIS Ability to Participate in Social Roles and Activities

    Time frame: 2 weeks, 3 months, and 6 months post-intervention

    This 6-item measure assesses participants' ability to participate in social roles and activities. The items measure difficulty engaging in social and recreational activities as well as usual work (including housework). Each item is rated on a scale from 1 (never) to 5 (always) and is reverse coded. Then the six items are summed with higher total scores indicating greater ability to participate in social roles and activities. The total scores are converted to T-scores with a range from 26.7 to 65.0 with higher scores indicating a better outcome. The population mean for T-scores is 50 with a standard deviation of 10. This is a secondary outcome.

  3. Functional Assessment of Cancer Therapy-General

    Time frame: 2 weeks, 3 months, and 6 months post-intervention

    This 27-item measure evaluates physical, social/family, emotional, and functional quality of life. For each of the 4 subscale scores (i.e., Physical Well-Being, Social/Family Well-Being, Emotional Well-Being, and Functional Well-Being), the items are summed, multiplied by the number of items, and divided by the number of items answered, with higher scores indicating better quality of life. Items are rated on 0 to 4 scales. The physical well-being subscale is the sum of 7 items (all items reverse-coded) with a range of 0 to 28. The social/family well-being subscale is the sum of 7 items (none reverse-coded) with a range of 0 to 28. The emotional well-being subscale is the sum of 6 items (5 items reverse-coded) with a range of 0 to 24. The functional well-being subscale is the sum of 7 items (none reverse-coded) with a range of 0 to 28. This is a secondary outcome measure.
