Telephone Support for Advanced Gastrointestinal Cancer Patients and Caregivers

This trial tests telephone-based Acceptance and Commitment Therapy (ACT), a type of psychotherapy, to reduce fatigue interference with activities, mood, and cognition in advanced gastrointestinal (GI) cancer patients and family caregiver burden. ACT includes mindfulness exercises (e.g., meditations, performing activities with greater awareness), identifying personal values (e.g., family, spirituality), and engaging in activities consistent with these values. A total of 40 patient-caregiver dyads were randomly assigned in equal numbers to either the ACT intervention or an education/support condition. Dyads in both conditions participated in six weekly 50-minute telephone sessions. Outcomes were assessed at baseline, 2 weeks post-intervention, and 3 months post-intervention. The investigators hypothesize that ACT will lead to improved primary and secondary outcomes as compared to education/support. Study findings will inform a large-scale trial of intervention efficacy.

This trial evaluates the feasibility, acceptability, and preliminary efficacy of telephone-based Acceptance and Commitment Therapy (ACT) on fatigue interference in advanced gastrointestinal (GI) cancer patients and family caregiver burden as well as secondary outcomes. The study team recruited advanced GI cancer patients receiving care at the Indiana University Simon Cancer Center or Eskenazi Health hospital. Potentially eligible patients were mailed an introductory letter signed by their oncologist and the PI along with a consent form. The letter had a number to call if they did not wish to be contacted further. A research assistant (RA) called all prospective participants who did not opt out approximately 1 to 2 weeks after the letter was mailed. The RA described the study as outlined in the consent form and answered any questions. Then the RA administered an eligibility screening to those who consented to participate. Eligible and consenting patients identified a potentially eligible family caregiver. If the family caregiver was eligible and consented to participate, then the patient and caregiver each completed a baseline phone assessment. Following baseline assessments, patient-caregiver dyads (N = 40 dyads) were randomly assigned in equal numbers to ACT or education/support using a stratified block randomization scheme to balance the groups by patient performance status (patient-reported Eastern Cooperative Oncology Group \[ECOG\] scores 0 or 1 vs. 2). Dyads in both study conditions completed 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 was assessed and recorded during each session. Feasibility will be examined via accrual, attrition, and adherence rates, and acceptability will be evaluated using a mixed methods approach (qualitative and quantitative). Blind interviewers assessed outcomes during follow-up phone assessments at 2 weeks and 3 months post-intervention.
