In a recent Scientific Reports study, researchers examined LncRNA TERRA levels in meningioma patients’ blood pre- and post-surgery. They observed that lower free and hybrid TERRA levels are associated with tumor characteristics and residual presence, suggesting TERRA’s potential as a non-invasive biomarker. This insight could aid clinicians in tailoring post-operative monitoring and treatment strategies—offering a promising approach for early detection and more effective management of meningioma.
