ASTRO: Deviating from radiation protocols increases risk of treatment failure and death
Date:10/30/2012

Other authors of the study include Adam P. Dicker, M.D., Ph.D., Chair of the Department of Radiation Oncology at Jefferson and the Kimmel Cancer Center at Jefferson, Laura Doyle, M.S., and Amy Harrison, M.S., of Jefferson's Department of Radiation Oncology, and Timothy Showalter, M.D., and Xinglei Shen, M.D.

The researchers examined two lung cancer trials, three trials for medulloblastoma, and trials for Ewing's sarcoma, pancreatic cancer and head and neck cancer, which included over 2,000 patients in total. They extracted information from the clinical trials, including number of patients included in QA analysis, definition of radiotherapy protocol deviation, and number of patients with and without radiotherapy deviations.

The frequency of radiation therapy deviations, they found, ranged from 8 percent to 71 percent. Those deviations were also associated with a significant decrease in overall survival, and with an approximately 75 percent increase in the risk of treatment failure and mortality.

"The magnitude of these effect sizes demonstrates that delivery of high-quality radiation therapy and having a rigorous QA program is critical for the successful execution of clinical trials and for the effective treatment of all cancer patients," said Dr. Dicker. "With such practices, deviations decrease and thus overall survival rates for cancer patients improve."
