目的证实卡培他滨联合奥沙利铂的改良方案(mXELOX),与FOLFOX6改良方案(mFOL-FOX6)比较,一线治疗转移性结直肠癌( mCRC)的非劣效性。方法采用随机、平行的Ⅱ期临床研究。310例未经治疗的mCRC患者被随机分配接受mXELOX或mFOLFOX6化疗( mXELOX 158例;mFOLFOX6152例),每2周为1周期。以总体反应率( ORR)、无进展生存( PFS)、总生存( OS)和化疗不良反应为评价指标。mXELOX 用法:卡培他滨(2000 mg/m2, d1~9)联合奥沙利铂(85 mg/m2, d1)。 mFOLFOX6用法:OXA 85 mg/m2,d1;继之予以亚叶酸钙400 mg/m2,d1静脉滴注2 h;然后5-FU 400 mg/m2,d1静脉推注后;予以5-FU 2400 mg/m2,46 h连续静脉滴注。结果分析符合方案数据集, mXELOX 与 mFOLFOX6之间的ORR、中位PFS、中位OS均无显著差异;ORR分别为45%与47%,单侧95%可信区间上限为13.8%(非劣效性所需的上限为15%);中位PFS分别为8.7个月与9.1个月;中位OS分别为20.9个月与21.5个月。 mX-ELOX与mFOLFOX6的3/4级不良反应发生率:神经病变分别为18%与19%( P>0.05);腹泻分别为15%与17%( P>0.05);手足综合征分别为19%与8%( P<0.01);中性粒细胞减少分别为17%和28%( P<0.01)。结论 mXELOX一线治疗mCRC非劣效于mFOLFOX6化疗。
目的證實卡培他濱聯閤奧沙利鉑的改良方案(mXELOX),與FOLFOX6改良方案(mFOL-FOX6)比較,一線治療轉移性結直腸癌( mCRC)的非劣效性。方法採用隨機、平行的Ⅱ期臨床研究。310例未經治療的mCRC患者被隨機分配接受mXELOX或mFOLFOX6化療( mXELOX 158例;mFOLFOX6152例),每2週為1週期。以總體反應率( ORR)、無進展生存( PFS)、總生存( OS)和化療不良反應為評價指標。mXELOX 用法:卡培他濱(2000 mg/m2, d1~9)聯閤奧沙利鉑(85 mg/m2, d1)。 mFOLFOX6用法:OXA 85 mg/m2,d1;繼之予以亞葉痠鈣400 mg/m2,d1靜脈滴註2 h;然後5-FU 400 mg/m2,d1靜脈推註後;予以5-FU 2400 mg/m2,46 h連續靜脈滴註。結果分析符閤方案數據集, mXELOX 與 mFOLFOX6之間的ORR、中位PFS、中位OS均無顯著差異;ORR分彆為45%與47%,單側95%可信區間上限為13.8%(非劣效性所需的上限為15%);中位PFS分彆為8.7箇月與9.1箇月;中位OS分彆為20.9箇月與21.5箇月。 mX-ELOX與mFOLFOX6的3/4級不良反應髮生率:神經病變分彆為18%與19%( P>0.05);腹瀉分彆為15%與17%( P>0.05);手足綜閤徵分彆為19%與8%( P<0.01);中性粒細胞減少分彆為17%和28%( P<0.01)。結論 mXELOX一線治療mCRC非劣效于mFOLFOX6化療。

Objective To demonstrate the non-inferiority of modified capecitabine plus oxaliplatin ( mXELOX ) versus modified 5-fluorouracil/leucovorin plus oxaliplatin ( mFOLFOX6 ) for the first-line treatment of metastatic colorectal cancer (mCRC).Methods A randomized,parallel group,stage Ⅱ clinical trial was carried out.310 patients with mCRC(mXELOX:n=158;mFOLFOX6:n=152)were enrolled and randomized to received by mXELOX or mFOLFOX6.The mXELOX consisted of a 2-hr intravenous infusion of oxaliplatin 85 mg/m2 on Day 1 plus oral capecitabine 1000 mg/m2 twice daily on Days 1 to 9 every 2 weeks.The mFOLFOX6 consisted of a 2-hr intravenous infusion of oxaliplatin 85 mg/m2 followed by a 2-hr infusion of LV 400 mg/m2 followed by 5-FU 400 mg/m2 given as an intravenous bolus injection and then 5-FU 2400 mg/m2 as a 46-hr continuous infusion every 2 weeks. The overall response rate(ORR),progression-free survival(PFS),overall survival(OS)and chemotherapy toxicities were assessed.Results In the per-protocol(PP)population,ORR,median PFS and OS difference between mXELOX and mFOLFOX6 groups was not significant (P>0.05),ORR was 45%with mXELOX and 47%with mFOLFOX6,the upper limit of the unilateral 95% confidence interval ( 13.8%) was below the non-inferiority margin of 15%.The median PFS was 8.7 months with mXELOX and 9.1 months with mFOLFOX6,and median OS was 20.9 and 21.5 months,respectively.The mXELOX patients had same grade 3/4 neuropathy(18%vs.19%)and diarrhoea(15%vs. 17%)as mFOLFOX6 patients(P>0.05),but significantly more grade 3/4 hand-foot syndrome(19% vs.8%)and less grade 3/4 neutropenia(17% vs.28%)than FOLFOX-6 patients(P<0.05).Conclusions mXELOX is non-inferior in terms of efficacy to mFOLFOX 6 in the first-line treatment of mCRC .
