Why study Brain tumour Biology Richard Grundy Overview

Why study Brain tumour Biology? ? ? Richard Grundy

Overview • Paediatric oncology is one of the medical success stories of the 80’s-90’s • Steady improvement on the overall survival of children with cancer BUT not CNS tumours – Only 50% survive • 10, 000 life years lost and considerable morbidity • Plateau and Stasis : More recently small advances only are being made and for some tumours little progress at all • Fight Fire with Fire

Children’s Brain Tumours : The Issues Brain tumours are relatively rare

Children’s Brain Tumours : The Issues Poor understanding of disease biology Brain tumours are relatively rare

Key Hypotheses • Tumours arising in different anatomical locations are genetically distinct entities. • Tumours arising indifferent age groups have distinct genetic aberrations. • Tumours of different histological grade have distinct genetic fingerprints. • Genetic markers can predict outcome in childhood CNS tumours. • Tumourigenesis arises from disordered neural development and involves distinct tumour specific pathways. • Development of large data sets linked to clinical parameters will enable the discovery of novel targets for therapy.

Biological studies • Using Biological studies to better understand or find : – ‘Markers’ that help us predict outcome or best treatment – pathways involved in the development of brain tumours – Where Brain tumours come from – New Drug Treatments

Improved Patient Management & Outcome International & National Clinical Trials & Biological studies Improved Diagnostic & Prognostic Imaging High resolution Molecular analysis of tumour samples Identification of molecular ‘fingerprint’ Children’s Brain Tumour Research Centre Fingerprint’ provides Novel prognostic Markers & targets for therapy Understanding ‘Why’ in the context of the Normal development of the Brain Why Does Treatment Fail ? Need New Drug Development and Delivery
