Trial supports MRI surveillance over preventive brain radiation in small-cell lung cancer

Results from the international phase 3 SWOG S1827 MAVERICK trial show that brain MRI surveillance alone improved cognitive failure-free survival compared with MRI surveillance plus prophylactic cranial irradiation (PCI) in patients with small-cell lung cancer (SCLC). The findings support MRI surveillance alone as the standard of care for patients with SCLC, according to research presented at the International Association for the Study of Lung Cancer (IASLC) 2026 World Conference on Lung Cancer (WCLC).
