WitrynaFigure 1 Overall survival in intensity-modulated radiotherapy (IMRT) group and 3-dimensional conformal radiotherapy (3D-CRT) group. The 1- and 2-year overall survival rates were 94.7% and 77.1% in the IMRT group compared with 76.7% and 52.5% in the 3D-CRT group ( P =0.072). Table 2 Analysis of prognostic factors for overall survival. WitrynaIMRT is a type of 3-D conformal radiation therapy. How it works Like 3-D conformal radiation, radiation beams are aimed at the tumor from several directions. IMRT uses many more smaller beams than 3-D …
