Breast cancer metastasis suppressor gene 1 correlates with progression of cancer: a Meta-analysis / 国际肿瘤学杂志

ABSTRACT

Objective To evaluate the association between the expression of breast cancer metastasis suppressor gene 1 (BRMS1) and the progression of cancer,and provide the basis for predicting the occurrence and metastasis of cancer.Methods Articles about BRMS1 with the clinical research literatures of cancer from PubMed,EMBase,China National Knowledge Infrastructure,Wanfang and VIP database were retrieved.The association between the expression of BRMS1 and tumorigenesis was evaluated by odds ratio (OR).The RevMan 5.3 software was used to complete the meta-analysis.Results A total of 27 articles were included,involving 2 282 cases in cancer group and 1 236 cases in the control group.The meta-analysis results showed that BRMS1 expression was significantly upregulated in cancer lesions compared with paired non-cancer (OR =0.10,95％ CIO.08-0.14,Z =15.37,P ＜0.000 O1).In the subgroup about the type of cancers,there was statistically significant difference in the pooled OR between breast cancer and the control group (OR =0.10,95％ CI0.05-0.20,Z =6.18,P ＜ 0.000 01).Conclusion The level of BRMS1 is negatively correlated with tumorigenesis including breast cancer.Low or absent BRMS1 expression in the tumor tissue may be an adverse predictive factor of tumorigenesis and metastasis.
