Gamma knife radiosurgery hits half-century mark with over a million patients treated

The first patient to have Leksell Gamma Knife® stereotactic radiosurgery in a clinical setting had his procedure to treat a pituitary adenoma at Sophiahemmet Hospital in Stockholm on January 27, 1968. By 2018 – Gamma Knife® radiosurgery’s 50th year – a staggering 1.1 million people around the world have received the therapy. Today, 330 clinical Leksell Gamma Knife units, distributed among 54 different countries, combine to treat 80,000 new patients each year.
