1、雷替曲塞單藥二線治療老年晚期結(jié)直腸癌的臨床研究李翔羅良平萬以葉姜莉江西省腫瘤醫(yī)院摘要:口的探討雷替曲塞單藥二線治療老年晚期結(jié)直腸癌的療效和安全性。方法將57例老年晚期結(jié)直腸癌患者隨機(jī)分為試驗(yàn)組(29例)和對(duì)照組(28例)。試驗(yàn)組采用雷替曲塞單藥方案化療,對(duì)照組采用F0LF1R1方案化療,觀察并比較2組治療效果及不良反應(yīng)。結(jié)果試驗(yàn)組與對(duì)照組的客觀有效率(RR)分別為13.8%和17.9%,疾病控制率(DCR)分別為58.6%和53.6%,差異無統(tǒng)計(jì)學(xué)意義(P>0.05)。2組屮位無進(jìn)展生存時(shí)間(PFS)分別
2、為4.4個(gè)月和4.9個(gè)月,差異無統(tǒng)計(jì)學(xué)意義(P>0.05)。試驗(yàn)組在惡心、嘔吐及腹瀉方而的不良反應(yīng)明顯低于對(duì)照組,差異有統(tǒng)計(jì)學(xué)意義(IK0.05)。結(jié)論雷替曲塞單藥方案二線治療老年晚期結(jié)直腸癌療效與FOLFIRI方案相當(dāng),且安全性更高,使用更方便。關(guān)鍵詞:老年晚期結(jié)直腸癌;雷替曲塞;二線治療;收稿日期:2017-03-06ClinicalStudyofRaltitrexedasSecond-lineChemotherapyintheTreatmentofElderlyAdvancedColorectaiC

8、直腸癌是常見的消化道惡性腫瘤,全球每年有超過100萬的新發(fā)病例,其中約有50%最后發(fā)展為晚期?;熓峭砥诮Y(jié)直腸癌的主要治療手段。老年患者因其機(jī)體機(jī)能狀態(tài)減退,并且往往合并多種基礎(chǔ)疾病,因此不能耐受強(qiáng)烈化療,在其一線治療疾病進(jìn)展后,二線化療用藥的選擇就亟需平衡高效和低毒的關(guān)系。雷替曲塞是一種直接抑制胸百酸合成酶的抗腫瘤藥物,與氟尿卩密曉相比,具有較好治療效果和較輕毒性,且與氟尿卩密噪無交叉耐藥。我科采用雷替曲塞單藥方案對(duì)比FOL
