Source: medicalxpress.comAuthor: staff When it comes to specialized cancer surgery, it's generally true that the more experienced the surgeon, the better the outcome. The same might hold true for radiation therapy used to treat head and neck cancer, according to a new study led by researchers Evan Wuthrick, MD, assistant professor of radiation oncology at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James), and Maura Gillison, MD, PhD, professor of internal medicine and epidemiology at the OSUCCC - James. Published in the Journal of Clinical Oncology with an accompanying editorial, the study compared survival and other outcomes in 470 patients treated with radiation therapy at 101 treatment centers through a clinical trial held from 2002 to 2005. The trial was sponsored by the National Cancer Institute and organized by the Radiation Therapy Oncology Group (RTOG). The findings indicated that patients treated at the less-experienced centers were more likely to have cancer recurrence (62 percent versus 42 percent at five years) and had poorer overall survival compared with those at the highly-experienced centers (51 percent versus 69 percent five-year survival, respectively). "Our findings suggest that institutional experience strongly influences outcomes in patients treated with radiation therapy for head and neck cancer," says Wuthrick, the paper's first author. "They indicate that patients do better when treated at centers where more of these procedures are performed versus centers that do fewer." Radiation therapy for head and neck cancer requires complex treatment planning that can vary considerably [...]
