ABSTRACT
Objective:
To compare the difference of intensity modulated radiation therapy (IMRT),3-D imensional conformal radiation therapy (3DCRT) for patients with upper esophageal carcinoma.Methods:
Ten patients with upper esophageal carcinoma were treated by intensity modulated radiation therapy and 3-D imensional conformal radiation therapy at the same TPS, the difference of exposure dose between target area and critical organ was compared by dose volume histogram(DVH) with the plan target volume (PTV) must reach 95% of the prescription dose.Results:
There was significant difference in dose of 95% plan target volume (PTV) (P 0.05). Compared with 3D-CRT, IMRT planning has better dose distribution and protection of normal tissue.Conclusions:
IMRT was better than 3DCRT, IMRT is the best radiation therapy.
