Abstract
Individuals from the family and social support network of patients with cancer can have a pivotal role in reinforcing patients' efforts to become and remain tobacco-free. This support is critical along the entire continuum of cancer care. Although NCI-designated Cancer Centers across the United States are increasingly offering tobacco cessation services as a result of the NCI Cancer Center Cessation Initiative (C3I), engaging patients' family and other support network in tobacco treatment is not yet a routine practice. To facilitate the consideration and involvement of patients' social support systems (including family, peers, and non-healthcare provider caregivers), we formed the C3I Family and Social Support Systems Working Group. This paper describes the current practices and challenges among C3I cancer centers centers in engaging the support systems of patients with cancer in order to reduce tobacco use and/or secondhand smoke exposure. Building on this knowledge, this Working Group proposes a research agenda to facilitate support persons' involvement in tobacco treatment as part of oncology care. The research priorities identified include establishing (1) evidence-based strategies for engaging family and social support systems in patients' cessation efforts, (2) interventions to provide cessation treatment options to support persons, and (3) best practices to routinely identify and engage family and social support systems in patients' cessation efforts.
