Targeted Therapy Drugs for Lung Cancer
One of the developments in lung cancer medicine is introduction of targeted treatments. Targeted therapy drugs work by targeting the cancer cells. They work by stopping cancer cells from dividing and growing them. These drugs also stop cancer from growing blood cells. They also encourage the immune system by attacking the cancer cells. Types of Targeted Drugs Erlotinib, Gefitinib and Afatinib They work by blocking proteins on cancer cells. These drugs block a specific kind of receptor on cell surface called Epidermal Growth Factor Receptor (EGFR). EGFR acts as doorways by allowing substances in that they can encourage cancer cells to grow and spread to other areas of the lung. Crizotinib, Ceritinib and Alectinib These are tyrosine kinase inhibitors and they work by blocking an enzyme called anaplastic lymphoma kinase (ALK). They have shown improvement in people with advanced non-small cell lung cancer who have ALK gene mutation. They work to block ALK and stop the growth of the tumor.
