Lung cancer is the most common cause of cancer-related death in adults . In 2013, 228,190 new cases of lung cancer and 159,480 deaths from lung cancer are estimated in the United States . The treatment of choice is surgical resection with lobectomy, but this is only suitable for localized, early-stage disease, with or without regional lymph node involvement [17,23]. Unfortunately, most patients have metastatic disease when diagnosis and are therefore not suitable for surgery . Chemotherapy regimens are considered first line treatment for advanced and metastatic lung cancer . However, these regimens are often associated with a decreased quality of life, without a significant improvement in prognosis.
