Study on Gene Evolution in Glioma Under Stress Therapy

Little is known about the evolution of genetic and epigenetic changes that occur in the progression of glioma. We inferred the evolution trajectories of matched pairs of primary tumors and progression tumor in situ fluid (TISF) based on deep whole-genome-sequencing data (ctDNA). A monocentric, Gene grouping controlled trial design was used to select patients. and to compare gene evolution of different subtypes of glioma under therapy. To predict the molecular reaction of bevacizumab treatment, clarify the mechanism of drug resistance of bevacizumab treatment.
