目的 :通过不同照射方法对鼻咽癌茎突后间隙侵犯进行放疗 ,以比较二者之间的疗效、探讨鼻咽癌茎突后侵犯的放疗方法。结果 :面颈联合野组以下简称面颈组 ,5年存活率 39.8% (35 / 88) ,与面颈分野以下简称耳前组 2 7.7(2 3/ 83)比较 ,有显著差别 ,P <0 .0 5。上颈部Ⅱ°、Ⅲ°软组织纤维化面颈组 2 5 .6 % (2 3/ 88)明显低于耳前组 34.6 % (2 8/ 83) ;虽然急性咽炎、口干等放射反应面颈组明显高于耳前组 ,但可耐受。结论 :鼻咽癌茎突后侵犯建议首选颈联合野 ,不宜使用鼻前野。
OBJECTIVE: To evaluate the radiotherapy of nasopharyngeal carcinoma after styloid process by different radiation methods. Results: The 5-year survival rate was 39.8% (35/88) in the face and neck joint field group, which was significantly different from 2 7.73 in the pre-anuricular group (P < 0 .0 5. The upper neck Ⅱ °, Ⅲ ° soft tissue fibrosis face neck group 25.6% (23/88) was significantly lower than the 34.6% (27/83) of the front ear group; although acute pharyngitis, dry mouth and other radiation reaction surface Neck group was significantly higher than the ear group, but tolerable. CONCLUSIONS: Nasal pharyngeal recurrence of nasopharyngeal carcinoma is recommended first choice of neck joint field, nasal anterior field should not be used.
