Abstract:
The discovery of multiple molecular mechanisms underlying the development, progression, and prognosis of lung cancer, has created new opportunities for targeted therapy. Each subtype is associated with molecular tests that define the subtype and drugs that may have potential therapeutic effect on lung cancer. In 2004, mutations in the epidermal growth factor receptor (epidermal growth factor receptor, EGFR) gene were discovered in non-small cell lung cancers (NSCLC), especially in adenocarcinomas. And they are strongly associated with sensitivity to EGFR-tyrosine kinase inhibitors (EGFR-TKIs). Moreover, in 2007 the existence of the echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase (EML4-ALK) fusion gene was discovered in NSCLC, and the same as EGFR-TKIs, ALK inhibitors are being found to be highly effective in lung cancers. At present, multiple molecular subtype of lung cancer and relevant targeted drugs are undering study. Here, we review the remarkable progress in molecular subtype of lung cancer and the related targeted therapy.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
