A Retrospective Study of Epidemiology and Prognostic Factors of Small Cell Lung Cancer

Abstract

Lung cancer has been the most common cancer overall for several decades. According to the last data of GLOBOCAN series of the International Agency for Research on Cancer there were estimated 1.8 million new cases in 2012 of which 1.2 million cases estimated to occur in males with lower incidence rate in females about 583,000 cases (Ferlay et al., 2013). Twenty seven percent of deaths from cancer in the United States in 2015 and 20% of deaths from cancer in the Europe in 2016 were related to lung cancer (Malhotra et al., 2016). Egypt was completely lacking incidence rates at national level till the national population based cancer registry program was offered. Lung cancer occupied third or fourth rank representing 5-7%of cancers (Hussein et al., 2014).
