Abstract
BACKGROUND: Lung cancer is the most common cancer worldwide, but epidemiologic data from developing countries are lacking. This article reports lung cancer incidence and survival in Rabat, the capital of Morocco. METHODS: All lung cancer cases diagnosed between 2005 and 2008 were analyzed using data provided by the Rabat Cancer Registry. The standardized rate was reported using age adjustment with respect to the world standard population, and the observed survival rates were calculated using the Kaplan-Meier method. RESULTS: Three hundred fifty-one cases were registered (314 males and 37 females), aged 27-90 years (median, 59 years). The most common pathological type was adenocarcinoma (40.2%) followed by squamous cell carcinoma (31.9%); the majority of cases were diagnosed at stage IV (52%). The age-standardized incidence rate was 25.1 and 2.7 per 100,000 for males and females, respectively, and the overall observed survival rates at 1 and 5 years were 31.7% and 3.4%, respectively. The clinical stage of disease was the only independent predictor of survival. CONCLUSION: The survival rate of lung cancer in Rabat is very poor. This finding explains the need for measures to reduce the prevalence of tobacco and to improve diagnostic and therapeutic facilities for lung cancer. Copyright Â
