The U.S. has successfully used a technique called step-and-shoot spot-scanning proton arc therapy (SPArc) to treat a patient’s adenoid cystic carcinoma (ACC) for the first time.
The SPArc works by targeting tumours with protons while sparing surrounding tissue.
The ACC is a relatively rare form of cancer that most commonly develops in the salivary glands or other regions of the head and neck.
But these technologies are very expensive one and are often suitable for a small patient population.
