For years, FLASH ultra-high-dose-rate radiotherapy was confined to research labs in Europe and the US. Last month, Aga Khan University Hospital in Nairobi officially launched East Africa’s first clinical FLASH program using a refurbished linac capable of delivering 100 Gy/s in under 200 ms.
Why does this matter?
Normal tissues receive 60–80 % less damage compared to conventional fractionation.
Treatment time drops from minutes to literal milliseconds—patients barely feel the beam.
Early results from the ongoing Phase I trial (20 patients with T1–T2 head-and-neck cancers) show zero Grade 3 skin reactions at 3-month follow-up.
