Imrt tomotherapy
WitrynaIntensity modulated radiation therapy, or IMRT, is a specialized form of conformal radiation that allows radiation to be more exactly shaped to fit the tumor. With IMRT, … WitrynaIMRT has recently become a popular technique for postoperative OCC, and encouraging results for 2- and 3-year LRC rates ranging from 53% to 91% have reported 1 – 3, 17 – 20 ( Table 4 ). In head and neck cancer, ECE +, PNI, LVSI, pT3-4, and two positive nodes were categorized as important prognostic factors.
