为了分析淋巴结评估数量以及阳性淋巴结所占比例随时间的变化趋势,并探讨其对结肠癌患者生存率的影响,研究者运用多因素logistic回归分析方法对2000~2011年期间在荷兰南部的8 616例行手术切除的M0结肠癌患者的资料进行了分析,以粗略的5年相对生存率作为对疾病特殊生存率的一个评估指标。该研究结果显示,有足够淋巴结评估数量者所占比例由2000年的13%增加到2011年的59%(P<0.000 1),而淋巴结阳性率在这期间没有明显变化(约为35%);2000~2002年与
In order to analyze the quantitative assessment of lymph nodes and the proportion of positive lymph nodes over time, and to explore its impact on the survival rate of patients with colon cancer, the researchers using multivariate logistic regression analysis of 2000-2011 in the Netherlands, 8 616 Routine surgical resection of M0 colon cancer patients were analyzed with a rough 5-year relative survival rate as an indicator of disease-specific survival. The results of this study showed that the proportion of those with adequate lymph node assessments increased from 13% in 2000 to 59% in 2011 (P <0.000 1), whereas the positive rate of lymph nodes did not change significantly during this period (about 35%) ; 2000 ~ 2002 and
