Glioblastoma: An Angiogenic Tumor

Hello. I am Professor Wolfgang Wick, Chairman of the Department of Neuro-Oncology, Heidelberg University Hospital in Heidelberg, Germany. Today I am going to summarize for you the findings on neuro-oncology, which is basically an update on glioblastoma from this year's European Cancer Congress (ECC) in Amsterdam.

Glioblastoma is a devastating disease with a median progression-free survival of just over half a year and median overall survival of 15-18 months. The standard of care consists of radiotherapy and chemotherapy, with temozolomide delivered during radiotherapy and for 6 more cycles after radiotherapy as a maintenance treatment. Improvement of this therapy is urgently needed, and a key target over the past years, both preclinically and clinically, has been angiogenesis. The glioblastoma is an extremely angiogenic tumor, and angiogenesis was tackled in the trials that I am going to discuss with the vascular endothelial growth factor (VEGF) inhibitor bevacizumab or with an anti-integrin, cilengitide, which is an RGD peptide that also targets the problem of neoangiogenesis -- pathological angiogenesis -- in this disease.
