ABSTRACT
Obejctive To compare the differences between conventional radiation therapy (3DCRT) and intensity modulated radiation therapy( IMRT) for locally advanced laryngeal carcinoma patients by ECLIPSE treat -ment planning system.Methods Six locally advanced laryngeal carcinoma patients ′treatment plans were de-signed as IMRT and 3DCRT according to ECLIPSE treatment planning system ,respectively.The following values were measured,such as V95%、D5%、D95%、Dmin and D mean of the target volume,and the D50,D33,D5, Dmax and Dmean of normal tissues.Results The dose coverage rate of GTV and GTVnd in the IMRT plan was compared to ECLIPSE treatment planning system with no statistical differences.However, there were obvious difference in CTV and some normal tissues.Conclusion Both IMRT and 3DCRT have good coverage to primary tumor and metastatic lymph nodes.IMRT can spare the parotid from high dose irradiation.
