ABSTRACT
Purpose:
To investigate the possibilities of three-dimensional conformal radiotherapy (3DCRT) in treating the patients with recurrent nasopharyngeal carcinoma;and planning optimization,dosimetry analysis for recurrent disease in different sites.Methods:
Three patients with recurrent disease in posterior area of styloid process、cavernous sinus and with maximum volume were analysed. Comparison was made for optimized 3DCRT treatment planning with different number of beams and angles of incidences.Results:
It is possible to significantly improve the dose coverage to target volume and the dose to critical organ was under the tolerance dose.Conclusions:
3DCRT may be a suitable alternative to conventional therapy in patients with recurrent nasopharyngeal carcinoma.
