1、NP方案化療聯(lián)合放療治療晚期非小細(xì)胞肺癌臨床療效分析【摘要】目的回顧分析NP方案聯(lián)合適形放療治療晚期非小細(xì)胞肺癌的臨床療效和毒副作用。方法32例Ⅲ期和Ⅳ期非小細(xì)胞肺癌患者,均行夾心序貫法NP方案化療聯(lián)合適形放療。NP方案為諾維本25mg/m2,d1,d8;DDP25mg/m2,d1-3,21天為1周期?;焹芍芷诤笮腥S適形常規(guī)分割放療,之后再化療。放射源為直線(xiàn)加速器X線(xiàn),15MV,照射劑量為36~66Gy。鎖骨上區(qū)預(yù)防照射,8MeV電子線(xiàn),20~30Gy。結(jié)果夾心序貫法化療聯(lián)合放療總有效率(RR)50.0%,其中1例達(dá)到完全緩解。ⅢA、ⅢB和Ⅳ期患者有效率(R
2、R)分別為80.0%,57.1%和30.8%。鱗癌、腺癌患者有效率分別為63.6%、22.2%。疾病控制率(DCR)為90.6%(29/32)。中位疾病進(jìn)展時(shí)間(TTP)為178天(60~446天)。主要毒副反應(yīng)為骨髓抑制、胃腸道反應(yīng)、放射性肺炎和放射性食管炎,均可以通過(guò)相應(yīng)措施予以糾正和緩解。結(jié)論NP方案化療聯(lián)合放療對(duì)晚期非小細(xì)胞肺癌有較好的近期療效和疾病控制率,毒副反應(yīng)能夠被患者耐受?!娟P(guān)鍵詞】非小細(xì)胞肺癌;化療;放療ABSTRACT:ObjectiveToanalyzeretrospectivelytheclinicaleffectsandsideeffe
