We conducted an umbrella review which synthetizes the findings of systematic reviews available in the literature that investigate the prognostic role of miRNAs as potential biomarkers in the field of tertiary prevention of head and neck Cancer (HNC). We selected systematic reviews in English related to HNC, with meta-analysis of observational studies that reported quantitative prognostic measures, hazard ratios (HRs), overall survival (OS) or disease-free survival (DFS). The methodological quality of the included reviews was assessed by using the AMSTAR-2 tool. The most reported miRNAs were the following: miRNA2, Let7 family and miR17, etc. Four out of six reviews particularly emphasized the link between miRNA21 expression and HNC patients. Recently the cumulative effects of sets of miRNAs have been increasingly studied and might be a stronger predictor of survival than single miRNA.

Abstract Head and neck cancer (HNC) represents the sixth most common cancer and the seventh cause of cancer-related deaths worldwide. Because of HNC high mortality and morbidity a support from the development of new biomarkers and personalized care for patients is needed. The role of micro-RNAs (miRs), as new epigenetic biomarkers, aimed at improving early diagnosis, predicting prognosis and establishing effective cancer therapies, has recently received considerable attention. The aim of this study was to conduct an umbrella review that synthetizes all the findings of systematic reviews already available in literature that investigate the prognostic role of miRs as potential biomarkers in the field of tertiary prevention of HNC. We selected systematic reviews, published in English until December 2019, related to human HNC with meta-analysis of observational studies that reported quantitative prognostic measures, Hazard Ratios (HRs), of Overall Survival (OS) or Disease-Free Survival (DFS). The methodological quality of the included reviews was assessed using the Assessment of Multiple Systematic Reviews AMSTAR 2 tool. Six systematic reviews were included in the umbrella review. The most reported miRNAs were: miR21; the Let7 family (c,d,g), miR17, 18 family, 20a, 29 family, 125b, 375. A total of 4 reviews assessed miR-21 expression in HNC patients, all showing its upregulation. The most frequently studied miR was miR21 which was reported either in the OS and DFS statistical analyses. The OS analysis showed a significant lower prognosis when miR21 was upregulated. It is involved in oncogenic and oncosuppressive cell signals pathways: the overexpression of miR21 was shown to be associated with cell proliferation, migration, invasion and survival. Recently the cumulative effects of sets of miRs has been increasingly studied and they might be stronger predictor of survival than single. The role of miRNAs as a prognostic biomarker specifically in HNC still need to be investigated. Key messages Some miRs were demonstrated to have as tumor-suppressing and oncogenic roles according to their level of regulation (up/down-regulation) in Head and Neck cancer patients. The role of miRs as prognostic biomarkers in HNC patients still need to be addressed by performing large scale to verify and enhance the power of evidence and clinical utility of these.

Background. Several studies have focused on the prognostic role of microRNA 222 in glioma. But different conclusions were drawn by these studies. We aimed to systematically evaluate the role of microRNA 222 in glioma by conducting a meta-analysis. Methods. A systematic literature search until January 2020 was conducted in Web of Science, EMBASE, Cochrane Library, PubMed, and China National Knowledge Infrastructure. The general characteristics and relevant data of nine articles were extracted. Hazard ratios (HRs) with 95% confidence intervals (CIs) were applied to evaluate the prognostic role of microRNA 222 in glioma. The primary outcomes were overall survival (OS) and disease-free survival (DFS). Results. Nine articles (11 data sets) with 1564 patients were included. We systematically evaluated the role of microRNA 222 for OS and DFS in glioma patients (HR for OS=1.72; 95% CI, 1.31-2.26; p=0.001; HR for DFS=1.02; 95% CI, 0.86-1.22; p=0.032). Subgroup analyses were performed according to the sources of patients, the types of the samples, the stages of the tumors, the methods for detecting the microRNA 222, and the sample size. No significant publication bias was found. Conclusion. In conclusion, our study provided evidence that a high expression of microRNA 222 was related to worse overall survival in glioma patients. However, given the limited study number, more high-quality studies are warranted in the future.

Objectives. The expression of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), a highly abundant and ubiquitously expressed long noncoding RNA (lncRNA), influences clinical parameters and may have prognostic value in cancer. This meta-analysis evaluated the prognostic role of MALAT1 in various cancers.Materials and Methods. Systematic literature searches of PubMed and EMBASE databases were conducted for eligible studies of the prognostic role of MALAT1 in cancer. Overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS) were analyzed. Summary hazard ratios (HRs) and 95% confidence intervals (95% CIs) were assessed to evaluate the influence of MALAT1 expression on patient prognosis.Results. Nine studies with a total of 932 patients were included in the analysis. Elevated MALAT1 expression was significantly correlated with poor OS (HR 2.02; 95% CI: 1.62–2.52;P<0.001;I2=0%). Subgroup analysis indicated that tumor type, histology type, ethnicity, and measurement technique did not affect the prognostic value of MALAT1 for OS. The HR of elevated MALAT1 for DFS was 2.78 (95% CI: 1.87–4.15;P<0.001;I2=0%).Conclusions. Elevated MALAT1 expression is correlated with poor OS in various types of cancer, suggesting that this gene is a prognostic factor for different types of cancer.

AbstractA consensus about the prognostic role of NIMA-related kinase 2 (NEK2) expression in various solid tumors has not been made yet. Thus, this meta-analysis aimed to systematically assess the prognostic role of NEK2 expression in patients with solid tumors. The eligible studies were identified through searching PubMed, Web of Science, and EMBASE. The hazard ratios (HRs) with their corresponding 95% confidence intervals (CIs) were used to evaluate the link between NEK2 overexpression and overall survival (OS) and disease-free survival/recurrence-free survival (DFS/RFS) of patients with solid tumors. A total of 17 studies with 4897 patients were included in this meta-analysis. Among these studies, all of them explored the association between NEK2 expression and OS of patients with solid tumors. Our pooled analysis indicated that NEK2 overexpression was significantly related to adverse OS (HR = 1.66; 95% CI: 1.38–2.00; P = 0.001). Additionally, there were six studies with 854 patients that investigated the association between NEK2 expression and DFS/RFS. Our pooled result indicated that there was a substantial relationship between NEK2 overexpression and poorer DFS/RFS (HR = 2.00; 95% CI: 1.61–2.48; P = 0.003). In conclusion, our meta-analysis indicated that NEK2 may be a useful predictor of prognosis and an effective therapeutic target in solid tumors. Nevertheless, more high-quality studies are warranted to further support our conclusions because of several limitations in our meta-analysis.

Background. Circulating microRNAs (miRNAs) are potential molecular biomarkers for cancer detection; however, little is known about their prognostic role in head and neck cancer. This current study is aimed at evaluating the role of novel miRNAs in the survival of head and neck cancer patients. Materials and Methods. We performed a systematic literature search using online databases for articles published between December 2006 and February 2019. A meta-analysis was conducted to assess the correlation between miRNA expressions and overall survival (OS) among the selected head and neck cancer studies. After multilevel screening by reviewers, meta-analysis was performed using hazard ratios (HR) and associated 95% confidence interval (CI) of survival to calculate a pooled effect size. Result. A total of 1577 patients across 13 studies were included in the literature review, with 18 miRNAs upregulated and 4 miRNAs downregulated predicting a poor overall survival. The forest plot generated using cumulated survival data resulted in a pooled HR value of 2.943 (95% CI: 2.394-3.618) indicating a strong association of dysregulated miRNA expression with a poor outcome. Only 2 miRNAs—low levels of miR-9 and high levels of miR-483-5p—were observed in two studies, both showing a significant association with overall cancer survival. Conclusion. To our knowledge, this is the first comprehensive systematic review and meta-analysis that examines the prognostic role of circulating miRNAs from blood in head and neck cancer patients. The combined effect estimates a HR across multiple studies and also supports the previous individual findings that an alteration in miRNA expression is highly associated with poor prognosis. This has the potential to use serum and/or plasma miRNAs as biomarkers and become novel tools for predicting the prognosis of head and neck cancer patients in the near future.

BACKGROUND: Recent studies have shown that microRNAs (miRNA) have prognostic values in cancers. This meta-analysis seeks to summarize the global predicting role of miR-155 for survival in patients with a variety of carcinomas.METHODS: Eligible studies were identified through multiple search strategies. Data were extracted from studies investigating the relationship between miR-155 expression and survival in cancer patients. Combined hazard ratios (HRs) of miR-155 for outcome were analyzed.RESULTS: A total of 16 studies dealing with various carcinomas were included for this meta-analysis. For overall survival, higher miR-155 expression could significantly predict worse outcome with the pooled HR of 2.057 (95% CI: 1.392–3.039). For relapse or progress-free survival, elevated miR-155 was also a significant predictor, with a combined HR of 1.918 (95% CI: 1.311–2.806,). In addition, subgroup analysis showed that higher expression of miR-155 had the trends to predict worse outcome in lung cancer. However, the HRs did not reach the statistical significance.CONCLUSION: Our findings suggest that miR-155 detection has a prognostic value in cancer patients. Regularly measuring miR-155 expression may be useful in clinical practice.

Background/Aims: Tumor-infiltrating fibroblasts are a heterogeneous population, and different subpopulations play differential roles in tumor microenvironment. However, the prognostic role of podoplanin+ fibroblasts in human solid tumors still remains controversial. Therefore, we performed the meta-analysis to better understand the role of this subpopulation in prognosis prediction for patients with solid tumor. Methods: We searched PubMed and EBSCO to identify the studies evaluating the association of intratumoral podoplanin+ fibroblast density detected by immunohistochemical method and overall survival (OS) and/or disease-free survival (DFS) in patients with solid tumor, then computed extracted data into hazard ratios for OS, DFS and clinicopathological features with STATA 12.0. Results: A total of 4883 patients from 29 published studies were incorporated into this meta-analysis. We found that podoplanin+ fibroblast infiltration significantly decreased OS and DFS in all types of solid tumors. In stratified analyses, podoplanin+ fibroblast infiltration was significantly associated with worse OS in cholangiocarcinoma, breast, lung and pancreatic cancer. And these cells were inversely associated with DFS in breast, lung and pancreatic cancer. In addition, high density of these cells significantly correlated with unfavorable clinicopathological features such as lymph node metastasis, TNM stage, lymphatic and vascular invasion of solid tumor. Conclusion: Podoplanin+ fibroblast infiltration leads to worse clinical outcome in solid tumors, implicating that it is a valuable prognostic biomarker and targeting it may have a potential for effective treatment.
