New Blood Test Reveals Whether Treatment is Working for Brain Cancer Patients
Researchers have revealed a new blood test that can determine whether brain cancer therapies are being effective. The diagnostic tool could guide glioblastoma physicians on whether to maintain current drug regimens, change medications, or halt interventions altogether. Adam Sonabend, a Northwestern Medicine neurosurgeon who co-directed a study published in Nature Communications, explained that using this test, treatment effectiveness becomes apparent after a single dose instead of months of waiting. This represents a major advancement for glioblastoma care. It could spare patients from continuing regimens that don't work while eliminating needless adverse reactions that diminish quality of life.
