Prospects for using high-throughput sequencing methods to identify new biomarkers of response and resistance to antitumor therapy

Abstract

High-throughput next-generation sequencing (NGS) technologies such as whole exome sequencing (WES) and bulk RNA sequencing (RNA-seq) allow identification of the new biomarkers of response and resistance to antitumor therapy. Retrospective studies have shown that the state of the tumor microenvironment (TME), identified via RNA-seq, is an independent prognostic and predictive biomarker. WES and RNA-seq technologies, along with classical immunohistochemistry, provide a comprehensive analysis of the tumor and TME. Affordability of high-throughput sequencing will enable personalization of antitumor pharmacotherapy.
