Though smoking causes adverse cancer treatment outcomes and smoking cessation can improve survival, prior literature demonstrates deficits in collecting tobacco use information in clinical trials. Results by Streck and colleagues represent a thorough structured assessment of tobacco use and alternative tobacco product use in patients enrolled in cooperative group trials. Among patients with predominantly non-tobacco related cancers, observations demonstrate that approximately 27% of patients reported using one or more forms of tobacco use after diagnosis. Alternative tobacco use was reported by many patients, including patterns of dual use. Results demonstrate the feasibility of collecting comprehensive structured tobacco use information, and further support the need to address tobacco and cessation even among patients with non-tobacco related cancers.
