Lung cancer has one of the highest incidence and mortality rates among all cancers worldwide. Many cases of lung cancer remain asymptomatic until the disease progresses to an advanced non-curable stage. Currently there are very few early detection techniques. Imaging tests such as CT scans, MRIs, and chest x-rays done on patients in response to other conditions, such as pneumonia or heart disease, can by accident detect lung cancers early in their asymptomatic form. These patients sometimes can respond well to treatment and may even be completely cured of lung cancer. ("Can non-small cell lung cancer be found early?")
Lung cancers are classified either as a non-small cell lung carcinoma (NSCLC) or as a small cell lung cancer (SCLC). The most common form of newly diagnosed lung cancer is NSCLC, which is found in 84% of newly diagnosed cases. There are three main types of NSCLC, adenocarcinoma, large cell carcinoma, and squamous cell carcinoma. Recently is has been proven that it is possible to detect minute amounts of tumor cells, tumor specific proteins, and gene alterations in patient blood samples. The ability to detect specific tumor related cells or genes in blood samples could be used to screen patients or assist in monitoring the treatment of cancer patients. These circulating tumor cells most probably originate one of two ways. Genes may have originated in circulating cancer cells or have been “shed” from the tumors themselves into the…
