In northern France, a region particularly affected by these diseases, we assembled a cohort (ALTAK study) to explore behavioural changes in smoking status during the year after diagnosis.Methods: We enrolled patients with first H&N or lung cancer and followed them for one year. Dimensions explored were socio-demographic features, lifelong types of smoking, alcohol use patterns, motivations and brakes to quit smoking and effective smoking cessation during the study. We compared characteristics between former (FSs) and current smokers (CSs) at baseline and after follow-up.Results: At baseline, being CS was positively associated with H&N cancer (p<0.0001) and hand-rolled cigarettes (p=0.007). For lung cancer, being CS was positively associated with hand-rolled cigarettes (p=0.008) and negatively associated with age (p<0.001). For H&N cancer, CSs showed a significantly higher level of alcohol dependence (p=0.03). Among 108 CSs at baseline, 65% had quitted smoking and 35% were still CSs at one year. FSs were older (p=0.01), smoked less cigarettes (p=0.002), had more previous quit attempts (p=0.01), were more self-confident regarding smoking cessation (p=0.01) and less enjoyed to smoke (p=0.01). Moreover, 70% FSs quitted within 3 months after diagnosis.Conclusion: This large cohort (371 patients) has allowed us to identify some factors of behavioral change in smoking status at baseline and over the year following cancer diagnosis
