RecruitingBehavioural interventionTelephone Support in Advanced Gastrointestinal CancerThe goal of this clinical trial is to see if telephone support programs help patients and their family caregivers adjust to advanced gastrointestinal cancer. A new telephone counseling program that involves practicing strategies for managing stress and symptoms will be compared to a telephone program involving education on quality-of-life issues and psychosocial support. The main questions it aims to answer are: Does our telephone counseling program lower the negative impact of patients' fatigue on their activities, emotions, and thinking abilities compared to a telephone program involving education and support? Does our telephone counseling program lower family caregivers' feelings of burden compared to a telephone program involving education and support? Participants in both study conditions will: Complete 6 weekly telephone sessions of counseling or education/support Complete a telephone booster session Complete 3 telephone interviews over about 5 months
