WebJul 24, 2024 · The ALCHEMIST trials are testing therapies that target two types of genetic changes that are thought to drive lung cancer growth: mutations in the EGFR gene and a rearrangement of the ALK gene. These changes are relatively rare: EGFR mutations are found in about 10% to 15%, and ALK rearrangement in 5% to 6%, of lung cancer patients.

WebJun 1, 2013 · In 2007, however, researchers discovered a different genetic mutation in tumors of some patients with NSCLC—a fusion of two genes, EML4 and ALK —that produces an aberrant form of the ALK tyrosine kinase protein that drives tumor growth. WebAs with ALK rearrangement and EGFR mutation, ROS1 fusion is an addictive oncogenic driver associated with adenocarcinogenesis in the lung peripheral epithelium (the terminal respiratory unit) unrelated to tobacco-driven carcinogenesis. The vast majority of reported cases are in adenocarcinomas. Histology of these cases has been quite variable.
