1、低位局部進(jìn)展期直腸癌治療中新輔助同步放化療聯(lián)合TME術(shù)的價(jià)值探宄摘要:目的全直腸系膜切除(totalmesorectalexcision,TME)是目前直腸癌手術(shù)治療的標(biāo)準(zhǔn)方法,但由于其復(fù)雜的結(jié)構(gòu),局部病灶清除不完全致使切除率降低,術(shù)后復(fù)發(fā)風(fēng)險(xiǎn)高。本文探討新輔助同步放化療聯(lián)合TME術(shù)治療對中低位局部進(jìn)展期直腸癌的有效性和安全性。方法選取本院2011年6月?2013年12月收治的60例中低位局部進(jìn)展期直腸癌患者,包括28例II期(T3-4T0M0),32例III期(T1-4N1-2M0)。所有患者均接受術(shù)前新輔助放化療(放療總劑量盆腔
2、區(qū)為40?46Gy,瘤床區(qū)為50?56Gy,1.8Gy/次,5次/w,同步化療采用F0LF0X4方案,行2個(gè)周期)。新輔助同步放化療結(jié)束4?6w后根據(jù)TME原則行手術(shù)治療。結(jié)果60例患者均完成新輔助放化療,放化療期間1?2級(jí)不良反應(yīng)發(fā)生率為70.0%,3級(jí)不良反應(yīng)發(fā)生率為10.0%,無4級(jí)不良反應(yīng)發(fā)生。患者臨床TNM分期下降。新輔助放化療結(jié)束后4?6w,60例患者行根治性手術(shù)治療,其中38例行低位或超低位前切除術(shù)(Dixon術(shù)),22例行腹會(huì)陰聯(lián)合切除術(shù)(Miles術(shù)),保肛率75.0%(45/60)。無1例發(fā)生圍手術(shù)期死亡,術(shù)后并
3、發(fā)生癥的總發(fā)生率為13.3%(8/60)。結(jié)論新輔助同步放化療聯(lián)合TME對治療中低位局部進(jìn)展期直腸癌有效并安全,其可以降低腫瘤分期、復(fù)發(fā)率,提高保肛率。關(guān)鍵詞:腸癌;新輔助療法;同步放化療;TME術(shù)Abstract:ObjectiveTME(totalmesorectalexcision,TME)iscurrentlythestandardmethodofsurgicaltreatmentforcolorectalcancer,butbecauseofitscomplexstructure,resultinginpartialdeb
