A groundbreaking free tool to help oncologists choose the best therapies for patients with non-small-cell lung cancer has been just launched by scientists at the 1st European Lung Cancer Conference. The online database brings together data on all the known somatic mutations (tumor derived – tumor specific) in a molecule called epithelial growth factor receptor (EGFR). Somatic mutations in this cell-surface molecule are known to affect treatment with the newer tyrosine kinase inhibitor class of drugs.
