Abstract
BACKGROUND: Active smoking at the time of diagnosis of a first head & neck (H&N) or lung cancer is associated with a worse cancer outcome and increased mortality. However, the compared characteristics of active vs. former smokers at cancer diagnosis are poorly known.
METHODS: In 371 subjects with a first H&N or lung cancer, we assessed: 1) socio-demographic features; 2) lifelong types of smoking; 3) alcohol use disorder identification test (AUDIT); 4) cannabis abuse screening test (CAST); and 5) Mini International Neuropsychiatric Interview (MINI). Using a multivariable regression model, we compared the profile of current smokers and past smokers.
RESULTS: Current smokers more frequently exhibited H&N cancer (OR 3.91; 95% CI [2.00-6.51]; p <  0.0001) and ever smoking of hand-rolled cigarettes (OR 2.2; 95% CI [1.25-3.88]; p = 0.007). Among subjects with lung cancer (n = 177), current smoking was primarily associated with ever smoking of hand-rolled cigarettes (OR 2.88; 95% CI [1.32-6.30]; p = 0.008) and negatively associated with age (OR 0.92; 95% CI [0.89-0.96]; p <  0.001). Among subjects with H&N cancer (n = 163), current smokers exhibited a significantly greater AUDIT score (OR = 1.08; 95% CI [1.01-1.16]; p = 0.03).
CONCLUSION: At the time of diagnosis of the first lung or H&N cancer, current smoking is highly associated with previous type of smoking and alcohol drinking patterns.
