For nearly four decades, a preventive form of brain radiation stood as a pillar of small-cell lung cancer care — effective against metastasis, yet quietly corrosive to the minds it sought to protect. A landmark international trial now suggests that modern imaging alone can shoulder that burden without the cognitive toll, inviting medicine to reconsider whether a long-trusted intervention has outlived its necessity. The MAVERICK trial does not yet answer every question, but it asks the most important one: when a treatment harms the very self it was meant to preserve, is there a better way?
MRI surveillance alone outperforms combined approach in small-cell lung cancer
Prophylactic cranial irradiation caused cognitive impairment and serious adverse events (7.9% grade 3-5 events, including one fatal encephalopathy) that MRI surveillance alone avoided.
