Br J Cancer:疾病进展时间和肝癌总生存期有什么联系?

2016-10-20 MedSci MedSci原创

在关于肝癌的临床试验中,疾病进展时间(TTP)被认为是与无进展生存期具有可比性的终点指标。但是目前关于TTP和总生存率(OS)之间的联系还没有得到很好评估。基于此,我们进行了此项系统回顾和荟萃分析。 我们检索了PubMed和EMBASE数据库获取数据源。符合条件的研究是:随机对照III期临床试验,评价了系统化疗或分子靶向治疗对晚期肝癌的疗效。使用Spearman秩相关系数评估(rs)和线性回

在关于肝癌的临床试验中,疾病进展时间(TTP)被认为是与无进展生存期具有可比性的终点指标。

但是目前关于TTP和总生存率(OS)之间的联系还没有得到很好评估。基于此,我们进行了此项系统回顾和荟萃分析。

我们检索了PubMed和EMBASE数据库获取数据源。符合条件的研究是:随机对照III期临床试验,评价了系统化疗或分子靶向治疗对晚期肝癌的疗效。使用Spearman秩相关系数评估(rs)和线性回归分析,评估TTP和OS之间的联系等。

数据显示,共纳入了18项研究,涉及6318例患者。来自每项研究的TTP增量效益与OS的增量效益相关。log (HRTTP)和log (HROS)的rs值和R2值分别为0.73 (95% CI 0.12-0.94, P=0.024)和0.57。

预测OS治疗效果的最小TTP为0.63。中位TTP和中位OS相关。TTP和OS之间的rs值为0.73(95% CI 0.40-0.89,P<0.001),R2值为0.42。

我们的研究结果表明,TTP可以替代OS,作为中晚期肝癌相关临床试验的测量指标。
