What is glioblastoma and how is it currently treated?
Glioblastoma is the most commonly diagnosed high-grade aggressive adult brain tumour, affecting around 3,200 people in the UK every year. It is incurable and has a devastatingly short average survival of just 12-18 months.
It is notoriously difficult to treat, and even after surgery, some cancer cells remain in the brain, leading to regrowth of the tumour. Once that happens, there is no effective treatment available for patients.
What will the Nottingham Centre set out to achieve?
The Centre aims to investigate these cells located at the edges of the tumour – known as the infiltrative margin – close to healthy brain cells. In the first study of its kind, researchers will combine advanced brain imaging scans performed during surgery and genomic analyses of infiltrative tumour tissue, with mathematical modelling and artificial intelligence (AI) techniques to provide predictions for the earliest signs of tumour recurrence based on an individual patient’s data.
When glioblastoma does return, it’s biology is much more similar to the biology of the infiltrative margin compared to other regions of the original tumour. Therefore, the team will focus on identifying drug targets in the infiltrative margin that could stop or delay cancer growth. This will allow for earlier targeted treatment after surgery, before recurrence shows up on regular imaging scans.
The goal is to enable researchers to predict the amount of time until glioblastoma recurrence for each person and then use molecular information to guide personalised surgery, radiotherapy and chemotherapy approaches, ultimately improving the prognosis and quality of life for patients with glioblastoma.
