Abstract
Lung cancer remains the leading cause of cancer-related deaths in the United States and Europe. Non-small cell lung cancer (NSCLC) is the most common type of lung cancer, accounting for approximately 75 percent to 80 percent of all lung cancers. The lungs are also a common site for the metastasis, or spread of cancer that originated elsewhere in the body. Unfortunately, poor medical condition or the location of the cancer within the lung makes many patients with NSCLC or lung metastasis ineligible for surgical removal of the tumour. These patients are often treated with chemotherapy and/or radiation therapy and/or targeted therapy. Long-term survival tends to be poor.
