Summary

Anti-angiogenic therapy is an important treatment strategy for recurrent glioblastoma. Our previous study provided evidence for a potential benefit of apatinib, a humanized monoclonal antibody against VEGFR-2, when added to temozolomide chemotherapy in patients with recurrent glioblastoma. Some patients showed durable responses and prolonged survival, with recorded survival times of over 30 months in 6.4% patients. However, a subset of patients progressed in 2 months. There is a strong need to better predict and monitor apatinib treatment response to prevent patients from adverse effects of ineffective therapy. In this study, whole genome sequencing and RNA-sequencing of formalin-fixed, paraffin-embedded tumor materials from the participants who received apatinib and temozolomide treatment will be performed to identify the response biomarkers and patients who may benefit most from apatinib, avoiding unnecessary potential toxicity and cost for those who are unlikely to benefit from the drug.
