P2.10-03 - Prevalence of Tobacco Use Disorder in Patients Diagnosed with Lung Cancer and Their Tobacco Use Characteristics (Now Available) (ID 1108)
10:15 - 18:15 | Author(s): Young Kyoon Kim
Tobacco use disorder (TUD), previously termed as nicotine dependence, was associated with increased risk of lung cancer. However, little is known about the prevalence of TUD and symptom manifestation in smokers with lung cancer. The aim of the present study was to investigate the prevalence of TUD using DSM-5 diagnostic criteria in patients diagnosed with lung cancer and determine their tobacco use characteristics.Method
A total of 200 histologically confirmed lung cancer patients who used tobacco within prior 12-month period at the time of diagnosis were recruited for this study. Participants were assessed with interviewer-administered questionnaires on symptoms of TUD and smoking-related behaviors and self-administered Fagerstrom Test for Nicotine Dependence (FTND).Result
The prevalence of DSM-5 TUD was 92.0% (n = 184). Of a total of 200 subjects, 23 (11.5%), 35 (17.5%), and 126 (63.0%) were classified as mild, moderate, and severe TUD, respectively. A total of 19 (81.3%) moderate TUD and 98 (77.8%) severe TUD patients had attempted smoking cessation. Of these subjects, 21 (21.4%) severe TUD patients and 12 (63.2%) moderate TUD patients had tried more than three times. The number of satisfied criteria of DSM-5 TUD was positively correlated with FTND score, cumulative lifetime smoking amount, and daily smoking amount.Conclusion
Smokers diagnosed with lung cancer had high prevalence of DSM-5 TUD. Their heavy and consistent tobacco use characteristics might be less motivated to maintain abstinence and make them to be less stick to quit.
