本研究的目的是通过荟萃分析全面评估p27表达与乳腺癌患者临床结局之间的关系。我们对20项研究(n= 6463例患者)进行了荟萃分析,评估p27表达与乳腺癌临床结局指标的相关性,包括总生存期(OS)、无病生存期(DFS)和无复发生存期(RFS)。使用RevMan 4.2进行数据池化。共有60%(15项研究中有9项)的研究显示p27高表达与OS之间存在显著相关性,而25%(8项研究中有2项)和60%(5项研究中有3项)的研究分别显示p27高表达与DFS和RFS之间存在相关性。相对危险度(RRs) OS组为1.34 (1.26 ~ 1.42)(P < 0.00001), DFS组为1.27 (1.10 ~ 1.47)(P= 0.001), RFS组为1.49 (0.92 ~ 2.42)(P= 0.10)。在淋巴结阴性乳腺癌患者中,OS和RFS的RRs分别为1.84 (1.30 - 2.59,P= 0.0005)和1.30 (0.20-8.50,P= 0.78)。在淋巴结阳性乳腺癌患者中,OS和RFS的RRs分别为2.99 (1.77 ~ 5.07,P < 0.0001)和1.49 (0.80 ~ 2.77,P= 0.21)。该荟萃分析表明,p27降低是总体和无病癌症生存差的独立预后因素。
The aim of this study was to comprehensively evaluate via a meta-analysis the association between p27 expression and clinical outcome in breast cancer patients. We conducted a meta-analysis of 20 studies (n= 6463 patients) that evaluated the correlation between p27 expression and indicators of breast cancer clinical outcome, including overall survival (OS), disease-free survival (DFS) and relapse-free survival (RFS). Data pooling was performed by RevMan 4.2. A total of 60% (9 of 15) of the studies showed a significant association between p27 high expression and OS, whereas 25% (2 of 8) and 60% (3 of 5) studies demonstrated a correlation between p27 high expression and DFS and RFS, respectively. The relative risks (RRs) were 1.34 (1.26–1.42) for OS (P < 0.00001), 1.27 (1.10–1.47) for DFS (P= 0.001) and 1.49 (0.92–2.42) for RFS (P= 0.10). In lymph node-negative breast cancer patients, the RRs for OS and RFS were 1.84 (1.30–2.59; P= 0.0005) and 1.30 (0.20–8.50; P= 0.78), respectively. In lymph node-positive breast cancer patients, the RRs for OS and RFS were 2.99 (1.77–5.07; P < 0.0001) and 1.49 (0.80–2.77; P= 0.21), respectively. This meta-analysis indicates that reduced p27 is an independent prognostic factor for poor overall and disease-free cancer survival.
