Abstract：Objective:Toanalyzethetheirradiationdose,therecenteffectandadversereactionsofthreedimensionalcon-formal radiotherapy(3D-CRT)and intensity modulated conformal radiotherapy( IMRT)on abdominal aorta. Methods:From January 2014 to October 2015,eighteen cases of para-aortic lymph node metastasis were analyzed. To compare and analyze the dose of 3D-CRT and IMRT for each patient before radiotherapy. According to the size and position of tumor,patients were divided into 3D-CRT plan group(three-dimensional group)and IMRT plan group(IMRT group),were treated by 6 MV ac- <br> celerator,to follow-up and observate the recent curative effect and adverse reactions. Results:95% target coverage dose,group was(5 079. 87±436. 13)cGy,three-dimensional group was(4 572. 73± 422. 57)cGy;95% target coverage dose,group was(5 123. 27 ±442. 78)cGy,three-dimensional group was(4 665. 90 ±339. 16)cGy;there was have significant differ-ence between the two groups(P<0. 01). The recent curative effect and adverse reaction rate has no obvious difference be-tween the two groups. Conclusion:IMRT technique on the radiation dose is 3D-CRT technology has a certain degree increase, no difference between the recent curative effect and adverse reactions.
