Çocukluk Çağı Kanserlerinde NTRK Somatik Füzyonları ve Tümör Agnostik Tedavi

Abstract

Neurotrophic tyrosine receptor kinase (NTRK) gene rearrangements have been recently identified and developed as one of the biomarkers that have been utilized as new targets for cancer therapy. NTRK gene fusions have taken their place in individualized targeted therapy by being used as a predictive (diagnostic) biomarker as well as a treatment target. Selective inhibitors of NTRK fusion proteins have potent efficacy in the treatment of NTRK fusion-positive solid tumors. Detection of these fussions have become important since the finding of new drugs for which U.S. Food and Drug Administration (FDA) granted approval are used on the treatment of patients who has NTRK fussions positive cansers. Clinical trials have shown that first generation tyrosine receptor kinase (TRK) inhibitors, larotrectinib (Vitrakvi, Bayer HealthCare Pharmaceutical Inc, New Jersey, U.S.) and entrectinib (Rozlytrek, Genentech Inc, California, U.S.), have potent efficacy in the treatment of NTRK fusion positive cancers. In the future, with the increase in the number of comprehensive studies on these drugs further information will become available and beneficial.
