"SBRT is now being investigated as a replacement to surgery for early-stage lung cancer. If this non-invasive technique is to replace surgery, not only does it need to be effective, but also safe," Dr. Welsh said. "Since this study shows that a 35Gy dose of radiation, obesity, and diabetes increase the risk of developing late negative side effects after high dose radiation, then we can take steps to reduce these side effects."
The study involved 265 patients with tumors within less than 2.5 centimeters of the chest wall, who were treated with SBRT between August 2004 and August 2008. Of these patients, 39 percent developed skin toxicity, while six percent developed acute pain and 22 percent developed chronic pain. In patients who are considered obese, diabetes mellitus was found to be a significant contributing factor in the development of chest pain.
