How Edge™ Radiosurgery Is Improving Patients’ Lives


The Dale and Frances Hughes Cancer Center at Lehigh Valley Hospital (LVH)–Pocono recently unveiled Edge,™ a leading-edge, minimally invasive stereotactic radiosurgery used to treat a wide range of cancers with incredible precision and accuracy.

LVH–Pocono is the first hospital in the region to offer Edge, capable of delivering higher doses of radiation to destroy cancer cells with no cutting, no anesthesia, fewer treatments and no in-hospital stay.

Treating cancer with better outcomes

Edge treats a wide range of cancerous and noncancerous tumors throughout the body, including those of the lung, prostate, brain, spine and other sites. It delivers treatments quickly, all while keeping track of tumor motion using advanced tracking technologies. Here’s how it’s changing lives:

  • Lung cancer – Varian Medical Systems’ Calypso® tracking system works hand-in-hand with Edge to track tumors in real time, so that even tumors that readily move – such as those of the lung – can be precisely targeted with radiation.
  • Prostate cancer – Greater accuracy means greater results and better quality of life. Published data suggests that Calypso and Edge can result in lower rates of bowel and sexual dysfunction side effects.
  • Brain and spine cancers – Radiation oncologists are able to utilize higher doses of radiation – delivered more quickly and accurately – to pinpoint brain and spinal tumors in fewer sessions while minimizing exposure to surrounding healthy tissues and structures.

The system also alerts the radiation oncologist if the patient undergoing treatment has moved in a way that could compromise accuracy. “Treatment with Edge only takes a few minutes, and most people are able to carry on their daily activities without feeling tired or run down,” says Sean Quinlan-Davidson, MD, radiation oncologist at the Hughes Cancer Center.

Edge versus other radiosurgery treatments

“Edge also allows radiation oncologists to treat more than one tumor in the body at a time,” says Quinlan-Davidson. “This isn’t the case with some other radiosurgery systems when you have to treat each individual tumor in a separate session,” he says.
