1、臨床醫(yī)學(xué)論文?適形放療聯(lián)合NP化療與單純NP化療治療晚期非小細(xì)胞肺癌臨床療效分析【摘要】目的回顧分析適形放療聯(lián)合化療與單純NP方案化療治療晚期非小細(xì)胞肺癌的臨床療效和毒副作用。方法76例ni期和IV期非小細(xì)胞肺癌患者資料。單純化療組31例,接受單純NP方案化療。NP方案為諾維本25mg/m2,dl,d8;DDP25mg/m2,dl3,21d為1周期。放療聯(lián)合化療組45例,接受適形放療聯(lián)合NP方案化療,NP方案化療兩周期后續(xù)行三維適形常規(guī)分割放療,之后再行NP方案化療。放射源為直線加速器X線,15MV,照
2、射劑量36?66Gy。鎖骨上區(qū)預(yù)防照射,8MeV電子線,20?30Gy。結(jié)果放療聯(lián)合化療組有效率(RR)57.8%,其中3例達(dá)到完全緩解,單純化療組有效率(RR)32.3%,兩組間P<0.05,其差異有統(tǒng)計(jì)學(xué)意義。放療聯(lián)合化療組中鱗癌RR65.6%,腺癌RR41.7%,PC0.05,其差異有統(tǒng)計(jì)學(xué)意義;MA、MB和IV期RR分別為83.3%,61?1%和33.3%,P<0.05,三者間差異有統(tǒng)計(jì)學(xué)意義,IHA期與IV期有效率PV0.01,其差異有統(tǒng)計(jì)學(xué)意義;初治、復(fù)治RR為60.1%、20.0%,P<0
3、.05,其差異有統(tǒng)計(jì)學(xué)意義。單純化療組川鱗癌與腺癌、IHB期勻IV期、初治與復(fù)治之間有效率差異無統(tǒng)計(jì)學(xué)意義。放療聯(lián)合化療組的中位疾病進(jìn)展時(shí)間(TTP)為178d(60?446d)。單純化療組的中位TTP為82d(25?233d)。放療聯(lián)合化療組的毒副反應(yīng)較單純化療組多一些,重一些,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,均可以通過相應(yīng)措施予以糾正、緩解。結(jié)論適形放療聯(lián)合NP方案化療較單純NP方案化療對(duì)晩期非小細(xì)胞肺癌有較好的近期療效,TTP也較長(zhǎng)些,毒副反應(yīng)能夠予以糾正、緩解。【關(guān)
