Instead of irradiating every patient's brain to prevent metastases, scan regularly and treat the few who develop them with focused radiation.
Rather than giving prophylactic cranial irradiation to every patient with small-cell lung cancer, this idea proposes MRI surveillance every three months with stereotactic radiosurgery reserved for the few who develop brain metastases. The rationale is that the benefit of PCI was shown before brain MRI was routine, and many patients irradiated would never have developed brain disease. The hypothesis is that surveillance with salvage SRS is non-inferior to PCI for overall survival and superior for cognition. A Japanese extensive-stage trial supports the approach, and the randomised SWOG S1827 MAVERICK trial of PCI versus MRI surveillance is the definitive test. Being tested at scale, it bears on the bottleneck of the brain as barrier and sanctuary.
