New AHRQ Study Updates Evidence for Treating Head and Neck Cancer

New research for treating head and neck cancer suggests that there is some evidence for intensity-modulated radiotherapy (IMRT) to reduce late xerostomia, or “dry mouth,” a serious side effect of cancer radiation, compared with an older radiation therapy technology called three-dimensional conformal radiation therapy. The study also found that more research is needed, but significant challenges exist in gathering additional data. According to the study, “Radiotherapy Treatments for Head and Neck Cancer Update,” head and neck cancer accounts for approximately 3 percent to 5 percent of cancer in the United States. The new study is an update of a 2010 research review from AHRQ
