The role of receptor tyrosine kinases in mediating glioblastoma resistance to radiotherapy and temozolomide

Abstract

Glioblastoma is the most common and aggressive form of malignant glioma. Currently, despite treatment with surgery followed by radiotherapy and the chemotherapeutic agent temozolomide (TMZ), mean patient survival time is approximately 12 months and the 5-year survival rate is close to 0%. A key factor for the dismal prognosis is tumour recurrence post-treatment which is largely due to: 1) the infiltrative nature of glioblastoma rendering complete resection impossible and 2) glioblastoma cell resistance to radio-chemotherapy. In this thesis we aimed to investigate the cellular mechanisms of receptor tyrosine kinases in conferring resistance to therapy. We first performed a literature search..
