目的评价核磁共振成像(Magnetic Resonance Imaging,MRI)和钼靶X线(Molybdenum target X-ray,X线)对中国乳腺癌诊断的准确率。方法:系统检索维普数据库、万方学术期刊数据库和中国期刊全文数据库中关于MRI和X线对中国乳腺癌诊断准确性的文献,检索时限均为从建库至2014年6月。采用Revman 4.2软件对符合条件的文献进行Meta分析,各研究之间进行异质性检验,使用固定效应模型计算合并OR值和95%可信区间(CI),并用漏斗图查看发表偏倚。结果:共检索出582篇有关MRI和X线对中国乳腺癌诊断准确性的文献,其中28篇文献符合纳入标准,包含3 804例试验对象,其中MRI组1 902例,X线组1 902例。Meta分析结果显示,合并OR=3.52,95%CI(2.89,4.29),MRI组对中国乳腺癌诊断的准确性是X线组的3.52倍,差异有统计学意义(P<0.05)。漏斗图显示图形基本对称。结论 MRI和X线这两种检查方法在中国乳腺癌诊断准确性方面差异存在统计学意义,乳腺癌经MRI诊断的准确性是经X线的3.52倍。
Objective To evaluate the diagnostic accuracy of magnetic resonance imaging (MRI) and Molybdenum target X-ray (X-ray) in Chinese breast cancer. Methods: The literature about MRI and X-ray diagnostic accuracy of breast cancer in China was searched systematically from VIP database, Wanfang Academic Journal Database and Chinese Journal Full-text Database. The search time was from the database to June 2014. Meta-analysis of eligible literature was conducted using Revman 4.2 software, heterogeneity was tested between studies, and the pooled OR and 95% confidence intervals (CI) were calculated using the fixed-effect model and publication bias was visualized using a funnel plot. RESULTS: A total of 582 articles on the diagnostic accuracy of MRI and X-ray for breast cancer in China were retrieved. Among them, 28 articles met the inclusion criteria and included 3 804 cases, of which 1 902 were in the MRI group and 1 902 in the X-ray group . Meta analysis showed that the OR of OR = 3.52,95% CI (2.89,4.29) in MRI group was 3.52 times of that of X-ray group in MRI group (P <0.05). Funnel diagram shows the basic symmetry of the figure. Conclusion The MRI and X-ray examinations have statistical significance in the diagnostic accuracy of breast cancer in China. The accuracy of MRI diagnosis of breast cancer is 3.52 times that of X-ray.
