Despite significant advancements in cancer therapy, a primary means to avoid lung cancer is prevention, and smoking cessation is the most basic intervention. Unfortunately, for long-term smokers, that intervention can sometimes be the most challenging.
According to data presented during the International Association for the Study of Lung Cancer (IASLC) 2022 World Conference on Lung Cancer, however, a personalized approach to smoking cessation has helped more than one-third of participants in a lung cancer screening program accomplish that goal.1
Results of the Yorkshire Enhanced Stop Smoking Study (YESS), which enrolled more than 1,000 smokers undergoing lung cancer screening, showed 7-day abstinence rates of 33.6% in the personalized intervention group and 30.3% in the control arm 3 months after attending a lung health check. Interestingly, subgroup analyses also showed that the intervention was significantly more effective in female vs male trial participants, the study authors reported.
“The presence of a co-located stop smoking service and offer of immediate, opt-out delivery of behavioral and pharmacologic support for quitting resulted in high uptake by people who smoke and attended a lung screening event,” said Rachael L. Murray, PhD, Professor of Population Health at the University of Nottingham, United Kingdom, who presented the data. “Quit rates were considerably higher 3 months after the lung health check, regardless of adding the personalized intervention, reinforcing the need for continued support.”
As Prof. Murray explained, smoking is the biggest contributor to lung cancer, and smoking cessation remains the most effective way to reduce lung cancer mortality. Although only 2% of people attending a lung cancer screening will receive a lung cancer diagnosis, said Prof. Murray, approximately 30% of people have a treatable condition in the form of tobacco dependence.
“Modeling work in the United States has shown that the addition of a tobacco control intervention will decrease overall deaths by 14% and increase the overall number of life years gained by 81%,” she continued. “Clearly, there are fantastic gains to be made with this type of intervention.”
To test the effectiveness of a personalized approach to smoking cessation, Prof. Murray and colleagues developed the YESS trial, which offered support on an opt-out basis to all eligible smokers attending a lung health check event, which included low-dose computed tomography (CT) screening.
The smoking cessation program involved nicotine replacement therapy, e-cigarettes, varenicline, and bupropion, as well as counseling and behavioral support. At 4 weeks, investigators validated smoking status with a carbon monoxide exhalation test.
Participants who consented to the study were then randomly assigned to the same program for an additional 8 weeks (the control arm) vs the same program plus personalized support (the intervention arm). The personalized intervention included scripted behavioral support delivered by …….
