目的探讨影响肺转移瘤术后疗效的因素和各种影响因素的作用程度。方法总结两家医院18年间手术治疗的肺转移瘤125例,统计术后生存期,分别采用Kaplan-Meier和Cox比例风险模型等单因素和多因素分析法,分析各因素对术后疗效的影响。结果单因素分析中,除了转移瘤类型外,转移灶数目、无瘤间期均对术后疗效有影响;多因素分析中三种因素均对术后疗效有影响,其中,转移灶数目对术后疗效影响最大,风险比为5.593。结论肺转移瘤术后疗效可受到上述三种因素的影响,在选择手术适应证时应慎重考虑这些因素。
Objective To investigate the effect of postoperative pulmonary metastases and the impact of various factors. Methods A total of 125 lung metastases were retrospectively analyzed in 18 hospitals in 18 hospitals in our country. The postoperative survival time was calculated by the single-factor and multi-factor analysis methods such as Kaplan-Meier and Cox proportional hazards model respectively. The effects of various factors on postoperative efficacy . Results In the univariate analysis, except for the type of metastases, the number of metastases and the tumor-free interval had an effect on postoperative efficacy. Three factors in multivariate analysis had an effect on postoperative efficacy. The number of metastases was The greatest effect after treatment, the risk ratio of 5.593. Conclusion The efficacy of postoperative pulmonary metastases can be affected by the above three factors, these factors should be carefully considered in the selection of surgical indications.
