鉴于癌症诊断后继续吸烟会增加不良健康结果的风险，强烈建议癌症患者戒烟。尽管目前缺乏关于其作为戒烟工具的安全性和有效性的证据，但电子烟正变得越来越受欢迎。为了指导肿瘤学家与患者就电子烟使用情况进行沟通，本文提供了首次发表的关于癌症患者使用电子烟和戒烟结果的临床数据。参与者（n=1074）包括吸烟者（癌症患者），他们最近参加了一个综合癌症中心的烟草治疗项目。评估标准人口统计学、烟草使用史和随访戒烟结果。从2012年到2013年，电子烟的使用量增加了三倍（10.6%对38.5%）。电子烟使用者比非使用者更依赖尼古丁，有更多的戒烟尝试，更有可能被诊断出患有胸部和头颈部癌症。通过完整的案例分析，电子烟使用者在随访时吸烟的可能性与非使用者一样（OR: 1.0; 95%CI 0.5-1.7）。使用意向治疗分析，电子烟使用者在随访时吸烟的可能性是非使用者的两倍（OR: 2.0; 95%CI 1.2-3.3）。观察到的高电子烟使用率与最近强调普通人群中电子烟使用量增加的论文一致。我们的纵向研究结果对电子烟在促进癌症患者戒烟方面的效用提出了质疑。需要进一步的研究来评估电子烟作为癌症患者戒烟治疗的安全性和有效性。
Given that continued smoking after a cancer diagnosis increases the risk for adverse health outcomes, cancer patients are strongly advised to quit. Despite a current lack of evidence regarding their safety and effectiveness as a cessation tool, electronic cigarettes (e-cigarettes) are becoming increasingly popular. In order to guide oncologists’ communication with their patients about e-cigarette use, this paper provides the first published clinical data about e-cigarette use and cessation outcomes among cancer patients. Participants (n=1074) included smokers (cancer patients) who recently enrolled in a tobacco treatment program at a comprehensive cancer center. Standard demographic, tobacco use history and follow-up cessation outcomes were assessed. A threefold increase in e-cigarette use was observed from 2012 to 2013 (10.6% vs. 38.5%). E-cigarette users were more nicotine dependent than non-users, had more prior quit attempts, and were more likely to be diagnosed with thoracic and head or neck cancers. Using a complete case analysis, e-cigarette users were as likely to be smoking at follow-up as non-users, (OR: 1.0; 95%CI 0.5–1.7). Using an intention to treat analysis, e-cigarette users were twice as likely to be smoking at follow-up as non-users, (OR: 2.0; 95%CI 1.2–3.3). The high rate of e-cigarette use observed is consistent with recent papers highlighting increased e-cigarette use in the general population. Our longitudinal findings raise doubt about the utility of e-cigarettes for facilitating smoking cessation among cancer patients. Further research is needed to evaluate the safety and efficacy of e-cigarettes as a cessation treatment for cancer patients.
