Abstract：Objective To study and compare the dose difference of intensity modulated radiation therapy (IMRT) and conventional radiation therapy(CRT) affecting tumor and normal tissues. Methods Thirty nasopharyngeal carcinoma patients in stage T3N1M0 received IMRT and CRT with CMS system. The dose affecting tumor and normal tissues was calculated respectively. Results There was no significant difference of the dose between IMRT and CRT, but the dose affecting the normal tissue was lower in IMRT than that in CRT. Conclusions The dose distribution to tumor target area is more precise with IMRT than that with CRT. The dose to the normal tissues is controlled more effectively with IMRT than that with CRT.
