1、临床医学论文•经肛门局部切除术治疗I期低位直肠癌作者:李曙光叶再元邵钦树王元宇马文东胡世荣屠世良【摘要]目的探讨I期低位直肠癌局部切除术临床应用的合理性。方法凹顾性分析93例I期(T1-2N0M0)低位直肠癌患者的资料。按手术方式不同分为:局部切除术组(45例)和根治术组(48例)。局部切除术组均行经肛门局部切除术,术后T1期(24例)行辅助放疗,T2期(21例)行辅助放、化疗。根治术组(T1期18例,T2期30例)均行根治术(行腹会阴联合切除术42例,低位前切除术6例),术后未行放、化疗。所有患者均随访5年以上。对两组患者的生存率、
2、复发率、并发症发生率进行比较分析。结果(1)局部切除术组和根治术组5年生存率T1期均为100%(24/24,18/18),T2期分别为86%(18/21)和93%(28/30),两组比较差异无统计学意义(P>0.05)。(2)局部切除术组和根治术组5年复发率T1期分别为4%(1/24)和0(0/18),T2期分别为19%(4/21)和7%(2/30),两组比较差异无统计学意义(P>0.05)。(3)局部切除术组并发症发生率为2%(1/45),根治术组为15%(7/48),前者显著低于后者(P<0.05)。结论对于I期低位直肠癌,经肛门
3、局部切除术联合术后放、化疗可获得与根治术相近的5年生存率'是一种合理的治疗方式。【关键词】直肠肿瘤;局部切除TransanallocalexcisionforstageIlowrectalcarcinoma[Abstract】ObjectiveToassessthevalidityoftransanallocalexcisionforstageIlowrectalcarcinoma.MethodsTheclinicaldataof93patientswithstageIlowrectalcarcinomawhounderwenttra
