A groundbreaking clinical validation study led by Imperial College Healthcare NHS Trust and Imperial College London suggests that a simple blood test could revolutionize the diagnosis of the deadliest form of brain cancer, glioblastoma (GBM). The technique, proven effective for glial tumors, including GBM, could eliminate the need for invasive and high-risk surgical biopsies, leading to earlier diagnoses, faster treatments, and potentially increased survival rates.
The world-first TriNetra-Glio blood test, developed by Datar Cancer Genetics and validated in the Brain Tumour Research Centre of Excellence, isolates circulating tumor cells in the blood. These cells can be analyzed with the same cellular detail as traditional tissue samples, providing a non-invasive and cost-effective diagnostic solution. The FDA has shown interest, raising hopes for a larger UK study that, if successful, could benefit patients within two years.
The technology is particularly crucial for fast-growing and aggressive cases where surgical biopsies are challenging. The blood test could be a game-changer for patients with inaccessible tumors due to location or other constraints.
Less than 1% of GBM patients live for over 10 years, with a prognosis as short as 12 months for many. The study’s findings are significant, as brain tumors are the leading cause of cancer-related deaths in individuals under 40. Brain Tumour Research emphasizes the urgent need for novel approaches and increased funding, urging the government and larger charities to invest more in research for improved treatments and, ultimately, a cure for this devastating disease.
