Even through smoking is a definite risk factor for lung cancer, it is possible for people who have never smoked to develop lung cancer. We aimed to describe the epidemiology of lung cancer in never smokers in Morocco. Also, an assessment of differences between men and women never smokers was performed. We analyzed retrospectively all patients diagnosed with lung cancer between 2014 and 2017. The results showed that of 606 patients, 157 (25.9%) were never smokers. Of these, seventy-nine patients (50.32%) were women. Women were more likely to be younger (p=0.034), had adenocarcinoma (p=0.046), and being in advanced stage of the disease (p=0.032). Men were more exposed to professional carcinogens (p<0.001). Tuberculosis was the most frequent previous lung disease in never-smokers, but no difference was noted between men and women. Performance status and comorbidities did not vary by sex. Never-smokers in Morocco represents a significant proportion of lung cancer. Evident epidemiologic differences are found between men and women never-smokers, notably, age, histological type and risk factor exposure.
