[Epidemiology of primary lung cancer among non-smokers in Senegal].

Abstract

INTRODUCTION\nAccording to global data for 2002, one quarter of new cases of primary bronchopulmonary cancer were non-smokers. We undertook this study with the aim of describing the epidemiological characteristics of non-smokers with primary bronchopulmonary cancer in the Dakar region of Senegal.\n\n\nMETHODS\nA multicenter descriptive study that included all non-smokers who presented with primary bronchopulmonary cancer between January 1st 2014\xa0and December 31st 2015. The data were captured on an Excel file and then transferred to Epi InfoTM 7\xa0software for analysis.\n\n\nRESULTS\nThe rate of diagnosis for primary bronchopulmonary cancers was 72.1\xa0%. The prevalence of non-smokers was 33.3\xa0%. The sex ratio was 1.27. The average age was 54.6\xa0years. More than a third of the sample were housewives. Carpenters and craftsmen exposed to metals predominated. Exposure to cooking oils was reported in one case. Three patients presented sequelae of pulmonary tuberculosis. Adenocarcinoma was the most common histological type and predominated in young subjects.\n\n\nCONCLUSION\nThe proportion of primary bronchopulmonary cancers diagnosed among non-smokers is increasing in Dakar. An analytical study of suspected risk factors would be helpful for prevention.
