Cancer stem cells; CD44; Meta-analysis; Outcome; Ovarian cancer

This meta-analysis study aimed to investigate the correlation between CD44-positive cancer stem cells (CSCs) and clinicopathological features and its effect on the survival of ovarian cancer patients. A comprehensive literature search in the electronic databases, including PubMed, EMBASE, and Wanfang (up to December 1, 2015), was conducted. Publications assessing the clinical or ... more

Cancer susceptibility; Gender; miR-146a; Polymorphism; Smoking

Evidence has shown that miR-146a is involved in carcinogenesis, and a common G/C variant (rs2910164) in the pre-miR-146a gene has been associated with various types of cancer. We summarized the data from 22 published case-control studies on the association between rs2910164 and cancer risk and performed subgroup analyses by ethnicity, gender and smoking status. We found a ... more

Biochemical recurrence; miR-146a; Polymorphism; Prostate cancer

Evidence has shown that miR-146a is involved in carcinogenesis and a common G/C variant (rs2910164) in the pre-miR-146a gene has been found to be associated with various cancers. We investigated the potential prognostic role of miR-146a polymorphism in prostate cancer after radical prostatectomy. Seventy-two southern Chinese with prostate cancer undergoing radical prostatectomy were ... more

Gastric cancer; miR-146a; miR-149; miR-196a2; Polymorphism

Here, we performed a case-control study to investigate the role of miR-146a, miR-149, and miR-196a2 polymorphisms in the development of gastric cancer using a hospital-based case-control design. A total of 186 gastric cancer patients and 186 control subjects were enrolled from Ren Ji Hospital between January 2012 and October 2014. MicroRNAs miR-146a, miR-149, and miR-196a2 were genotyped ... more

Hepatocellular carcinoma; miR-146a; miR-196a2; MiR-499; Polymorphism

Hepatocellular carcinoma is one of the most common malignant tumors worldwide; it is estimated that there were 782,000 new cases in 2012. MicroRNAs (miRNAs) play an important role in carcinogenesis by regulating oncogenes and tumor suppressors. We investigated the role of miR-146a, miR-196a2, and miR-499 polymorphisms in the risk of hepatocellular carcinoma in a Chinese population. ... more

Classic Kaposi sarcoma; miR-146a; miR-149; Polymorphism

Classic Kaposi sarcoma is a type of vascular proliferative inflammatory disease. Previous studies have reported significant associations between microRNAs expression and the development of classic Kaposi sarcoma. Here, we conducted a case-control study to investigate the association between miR-146a and miR-149 genetic polymorphisms and ... more

Arg188His; Gene polymorphism; Ovarian cancer; X-ray repair cross-complementing group 2 (XRCC2)

Numerous studies have evaluated the association between the Arg188His polymorphism of the X-ray repair cross-complementing group 2 (XRCC2) gene and ovarian cancer risk. However, the specific association is still controversial. This meta-analysis was therefore designed to clarify these controversies. Relevant case-control studies were enrolled in the meta-analysis. Quality ... more

Nuclear factor-kB; Ovarian cancer; Single nucleotide polymorphisms

Nuclear factor-κB (NF-κB), a transcription factor that is activated by various stimuli, is associated with the pathogenesis of several cancers. One functional polymorphism, -94 insertion/deletion ATTG (rs28362491), in the human NFKB1 gene (one member of the NF-κB gene family) is associated with increased risk of various cancers. However, only one study has reported that rs28362491 ... more

A1298C polymorphism; MTHFR gene; Ovarian cancer

Numerous studies have evaluated the association between the MTHFR A1298C polymorphism and ovarian cancer risk. However, the specific association is still controversial. Therefore, we performed the present meta-analysis. A systematic literature search of PubMed and Embase databases was undertaken in August 2014, and the reference lists of articles were retrieved. ORs with their 95%CI were ... more

Case-control study; COMT; Meta-analysis; Ovarian cancer; Single nucleotide polymorphism; Systematic review

The objective of this study was to perform a systematic review of the correlations between the single nucleotide polymorphism rs4680 in the catechol-O-methyltransferase (COMT) gene and susceptibility to ovarian cancer. A computer search was carried out for relevant case-control studies published between January 2000 to January 2014 in databases such as Ovid, EBSCO, PubMed, CNKI, CBMDISC, VIP, ... more
