无复发生存率
在ME LLND和单独ME组中,分别有107例和113例患者复发或死亡,其中18例复发或死亡发生在最初计划的5年分析之后。7年RFS在ME LLND组为71.1%(95%c.i.66.0至75.6),单独ME组为70⋅7%(65.5至75.2)(图1a),HR为1.09(95%c.i.0.84至1.42;非劣效性P=0.064)。这一发现与初步分析结果相一致,初步分析并没有证实单独ME和ME LLND相比的非劣效性。
总生存率和无局部复发生存率
在7年的随访中,ME LLND组和单独ME组分别有59例和68例死亡。7年总体生存率ME LLND组为86⋅8% (95% c.i.82.7 至 90.0),单独ME组为 84.0%(7 9.7 至87.5) (图2),HR为1.20 (95% c.i.0.85至70)。在7年的随访中,ME LLND组和单独ME组分别有68例和84例患者局部复发或死亡。7年局部无复发生存率,ME LLND组是82.9%(78.5至86.5),单独ME组为78.9%(74.1至8 2.9) (图3),HR为1.34(0.97至1.84)。局部复发的模式如表2所示。ME LLND组7年累积局部复发率为7.5%(5.0至10.6)。
无复发生存率的亚组分析
图6显示了RFS的亚组分析。在临床III期患者中,ME LLND组的RFS优于单独ME组(HR 1.49,95%c.i.1.02至2.17)。在临床II期肿瘤患者中,两个治疗组的RFS无显著差异(HR 0.82,0.56至1.19)。病理Ⅲ期疾病患者,ME LLND的RFS改善没有统计学意义(HR 1.31,0.93至1.84)。病理I期和II期肿瘤患者的RFS在两组之间没有差异。
和ME联合LLND相比,本研究的长期随访数据并不支持在无影像学淋巴结肿大的局部进展期直肠癌患者单用ME的非劣性。因此,我们建议联合使用ME与LLND,尤其是术前未常规进行CRT的临床Ⅲ期疾病的患者,而对于临床II期肿瘤患者,LLND可以不施行。
