Treating Lung Cancer with SBRT
A 76-year-old woman with early stage lung cancer was among the first patients to benefit from SBRT on the Novalis Tx platform, delivered using RapidArc. "Her treatments took less than 30 minutes to deliver; comparable treatments using older radiosurgery technology had been taking anywhere from 45 to 60 minutes a day, sometimes more," said Dr. Kresl, medical director for the Department of Radiation Oncology. "In addition to being faster to deliver, and so more comfortable for this patient, the RapidArc treatment plan was superior in terms of both the amount of dose we could direct at the tumor, and the degree to which we could minimize exposure of the patient's healthy tissues -- particularly the lung and spinal cord. This patient was adamantly opposed to conventional surgery and the associated risks. Fortunately, we had a noninvasive option for her that is superior to standard forms of radiation therapy."

Another recent radiosurgery patient was treated for a tumor at the top of his nasal cavity, which was invading his skull, destroying bone, causing significant pain, and affecting his optic nerve, making his left eye useless.
This patient was treated in five 20-30 minute sessions, delivered on an outpatient basis over five consecutive days, without the need for anesthesia. "Four weeks later, the tumor had shrunk considerably, the patient was off his pain medications, and had regained the use of his left eye," Dr. Kresl said. "He was very excited, and we fully expect to see further regression of the tumor in future follow-up visits."
