摘要
目的 探讨准适形放疗技术在鼻咽癌治疗中的价值。方法 将 96例初治鼻咽癌随机分为准适形组及常规组各 48例 ,准适形组采用面罩固定、定位、拍片、划靶区、作挡块、验证、等中心外照射 ;常规组行常规放疗。结果 准适形组残留 8例 ,常规组 13例 (P>0 0 5 ) ;两组总的 3年生存率为 75 0 %,无瘤生存率 62 5 %,其中准适形组为 68 75 %,常规组 5 6 2 5 %,P =0 2 0 6。急性放射性口腔黏膜炎 ,准适形组明显低于常规组 ,P =0 0 0 1。结论 准适形放疗可提高疗效 ,减轻放疗反应。
Objective To evaluate the value of quasi-conformal radiotherapy (qCRT) for nasopharyngeal carcinoma (NPC) Methods 96 cases with NPC were randomized into two groups: the quasi-conformal radiotherapy and conventional radiotherapy (cRT), patients in qCRT were fixed by face mask, isocentre-localized, taken films, drawn GTV and PTV, made blocks, verificated and irradiated,patients in cRT received with routine radiotherapy Results qCRT's and cRT's nasopharyngeal tumor residual were 8 cases and 13 cases( P >0 05) Overal 3-survival and free-disease survival rates were 75 0% and 62 5%, qCRT's and cRT's 3-free-disease survival rates were 68 75% and 56 25%, P =0 206 qCRT's acute mucositis induced by radiation is lower than cRT's, P =0 001 Conclusions The quasi-conformal radiotherapy will increase the curative effects of NPC, decrease the side effects of radiation
