The study intervention consists of the early integration of palliative care services into standard oncology care in an outpatient setting for patients with advanced lung and non-colorectal gastrointestinal malignancies who are not being treated with curative intent. The palliative care services provided to patients randomized to the intervention will be provided by board-certified physicians and/or advanced practice nurses and will focus on the following areas: (1) developing and maintaining the therapeutic relationship with the patients and family caregivers; (2) assessing and treating patient symptoms; (3) providing support and reinforcement of coping with advanced cancer in patients and family caregivers; (4) assessing and enhancing prognostic awareness and illness understanding in patients and family caregivers; (5) assisting with treatment decision-making; and (6) end-of-life care planning.
