Malignant Epithelial Tumors of the Lung

Lung cancer is an aggressive type of malignancy with a relative 5-year survival rate of 18.1% (2007-2013). On the brighter side, rates for new lung cancer cases have been falling on average 2% each year over the last 10 years, while death rates have been falling on average 2.5% each year from 2005 to 2014. This changing landscape of lung cancer histology not only facilitates the understanding of lung cancer etiology but also has important implications for the selection of targeted therapies and patient management underscoring the need for most accurate histopathological evaluation. It is hoped that in the future, better educational campaigns, earlier disease detection, and newer treatment options will decrease the incidence of lung cancer and improve patient survival.
