Ros1 gene rearrangement is a mutation that occurs with some lung cancers Testing can identify it so targeted therapy drugs can be started. If your lung cancer hasn’t yet spread and it’s in an early stage, you might be a candidate for surgery to have the lung cancer completely removed If not, the lung cancer can be treated with a targeted therapy. Targeted therapy with ros1 tyrosine kinase inhibitors (tkis) has significantly improved the outcomes for these patients Objective the objective of this evidence review is to summarize the evidence and guidelines on testing for egfr, braf, and kras variants
Alk, ros1, and ret rearrangements Common targets common targets in lung cancer though targeted therapy is a relatively new form of treatment, researchers have already identified common targets in lung tumors These include epidermal growth factor receptor (egfr), anaplastic lymphoma kinase (alk), and the ros1 gene. Which new genes should be tested for lung cancer patients Ros1 testing must be performed on all lung adenocarcinoma patients, irrespective of clinical characteristics ( s ) ros1 ihc may be used as a screening test in lung adenocarcinoma patients
By enabling selection of effective targeted treatment, it can help avoid ineffective chemotherapy, unnecessary toxicity, and faster cancer progression.
