Photo provided Head and neck cancer surgeons at MUSC Hollings Cancer Center are excited about the possibilities of a new nerve fluorescing product they’re testing in a phase III clinical trial. Developed by Alume Biosciences, the product is a dye that combines a fluorescing molecule with a peptide that binds to nerves, illuminating them to make them easier for surgeons to spot. “Taking the tumor out is easy – finding the nerve and making sure you save the nerve is the critical part. This is a trial to help determine if using this dye during surgery improves the ability of surgeons to visualize and preserve nerves,” said Jason Newman, M.D., Head and Neck Cancer Division director. Some areas of the body have more nerves than others, and the head and neck area is one where many small nerves control critical functions. “I always tell patients, ‘If we take out a tumor in your cheek, that could be a three-hour surgery. If you took the same tumor out of the skin of your back, it could be a 10-minute surgery right in the office. And the difference is that the nerve that moves your entire face is there on the cheek,’” Newman said. Alexandra Kejner, M.D., was the first at Hollings to use the product, on a patient who needed a total thyroidectomy. “During that surgery, we’re monitoring the recurrent laryngeal nerve [...]
