Background This novel meta-analysis was conducted to systematically and comprehensively evaluate the prognostic role of the pretreatment PNI in patients with head and neck neoplasms (HNNs) undergoing radiotherapy. Methods Three databases, PubMed, Embase, and Web of Science, were used to retrieve desired literature. Hazard ratios (HRs) with 95% confidence intervals (CIs) were extracted and pooled by fixed-effects or random-effects models to analyze the relationship between the PNI and survival outcomes: overall survival (OS), distant metastasis-free survival (DMFS), and progression-free survival (PFS). Results Ten eligible studies involving 3,458 HNN patients were included in our analysis. The robustness of the pooled results was ensured by heterogeneity tests (I2 = 22.6%, 0.0%, and 0.0% for OS, DMFS, and PFS, respectively). The fixed-effects model revealed a lower pretreatment PNI was significantly related to a worse OS (HR = 1.974; 95% CI: 1.642–2.373; P<0.001), DMFS (HR = 1.959; 95% CI: 1.599–2.401; P<0.001), and PFS (HR = 1.498; 95% CI: 1.219–1.842; P<0.001). The trim-and-fill method (HR = 1.877; 95% CI: 1.361–2.589) was also used to prove that the existing publication bias did not deteriorate the reliability of the relationship. Conclusion The pretreatment PNI is a promising indicator to evaluate and predict the long-term prognostic survival outcomes in HNN patients undergoing radiotherapy.

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.

Backgrounds. Both pretreatment serum CRP (C-reactive protein) level and ALB (albumin) level have been found to be predictive of survival for multiple malignancies including sarcoma. Since both of the GPS (Glasgow prognostic score) and CAR (C-reactive protein to albumin ratio) are based on the combination of CRP and ALB, we conducted a meta-analysis to evaluate the prognostic role of these two parameters for sarcoma patients. Methods. A detailed literature search was conducted in MEDLINE, Embase, and Cochrane Library for relevant research publications written in English. Patients’ clinical characteristics, outcomes of overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS) were extracted. Pooled hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) were combined to evaluate the prognostic role of GPS or CAR. Results. Twelve articles containing 2695 patients were identified as eligible studies. The results showed that an elevated GPS was significantly correlated with poor OS (HR=2.42; 95% CI: 1.98-2.94; p<0.001; fixed-effects model), DSS (HR=2.28; 95% CI: 1.75-2.97; p<0.001; fixed-effects model), and DFS (HR=2.05; 95% CI: 1.62-2.60; p<0.001; fixed-effects model). A higher CAR also was shown to be significantly correlated with poor OS (HR=2.23; 95% CI: 1.70-2.92; p<0.001; fixed-effects model) and DFS (HR=1.81; 95% CI: 1.7-2.58; p=0.001; fixed-effects model). Conclusion. An elevated GPS is predictive of poor survival in patients with sarcomas and is promising to be used as a factor for risk stratification. A higher CAR value is also predictive of poor survival; however, the optimal CAR cut-off value is still to be determined.

Abstract PURPOSE: This meta-analysis aims to evaluate the impact of delaying surgery in operable breast tumor patients after neoadjuvant chemotherapy (NAC) on survival. METHODS:An electronic literature retrieval was conducted on PubMed/Medline and EMBASE((between January 2000 and June 2020).The primary end point was overall survival(OS),secondary end points included disease-free survival (DFS) or recurence-free survival (RFS).The HR with 95% confidence intervals were calculated using a random-effects or fixed-effects model. RESULTS:The combined HR for OS was 1.51 (95% CI:1.30-1.76; P=0.000) by fixed effects model.No statistically significant heterogeneity was found (P=0.168, I 2 =31.3%).The pooled HR for RFS/DFS was 1.59 (95%CI:1.30-1.95,I 2 = 66.0%) by random-effects model,with significant heterogeneity. CONCLUSION:Our meta-analysis revealed a significant adverse association between longer TTS after NAC and more inferior OS and RFS/DFS in patients with breast cancer.Clinicians and patients should minimize surgical delay after NAC as much as possible.

Context Infant colic is a common and distressing disorder of early infancy. Its etiology is unknown, making treatment challenging. Several articles have suggested a link to migraine. Objective The objective of this article was to perform a systematic review and, if appropriate, a meta-analysis of the studies on the relationship between infant colic and migraine. Data sources Studies were identified by searching PubMed and ScienceDirect and by hand-searching references and conference proceedings. Study selection For the primary analysis, studies specifically designed to measure the association between colic and migraine were included. For the secondary analysis, studies that collected data on colic and migraine but were designed for another primary research question were also included. Data extraction Data were abstracted from the original studies, through communication with study authors, or both. Two authors independently abstracted data. Main outcomes and measures The main outcome measure was the association between infant colic and migraine using both a fixed-effects model and a more conservative random-effects model. Results Three studies were included in the primary analysis; the odds ratio for the association between migraine and infant colic was 6.5 (4.6–8.9, p < 0.001) for the fixed-effects model and 5.6 (3.3–9.5, p = 0.004) for the random-effects model. In a sensitivity analysis wherein the study with the largest effect size was removed, the odds ratio was 3.6 (95% CI 1.7–7.6, p = 0.001) for both the fixed-effects model and random-effects model. Conclusions In this meta-analysis, infant colic was associated with increased odds of migraine. If infant colic is a migrainous disorder, this would have important implications for treatment. The main limitation of this meta-analysis was the relatively small number of studies included.

Circulating Micrornas

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.

ObjectiveThe aim of this study was to compare the survival outcomes of adenosquamous carcinoma (ASC) and adenocarcinoma (AC) of the cervix.MethodsWe searched PubMed and Embase for observational studies that compared the outcomes of 2 histologic subtypes. Hazards ratios (HRs) with 95% confidence intervals (CIs) were calculated with a fixed effects model.ResultsA total of 17 studies were included in the analyses. Patients with ASC were associated significantly with poorer overall survival (death HR, 1.27; 95% CI, 1.12–1.43; I2= 0%) and recurrence-free survival (recurrence HR, 1.43; 95% CI, 1.05–1.95; I2= 19.4%) than those with AC. For clinical stages I and II in particular, ASC predicted significantly poorer outcomes compared with AC (death HR, 1.41; 95% CI, 1.17–1.70; I2= 0%).ConclusionsThis meta-analysis suggests that ASC may have poorer outcomes compared with AC of the cervix.

Abstract Background: A growing number of researches suggests that microRNAs (miRNAs) as oncogene or tumor suppressor genes play a fundamental role in various kinds of cancers. Among them, miR-24-3p, as a star molecule, is widely studied. However, the prognostic value of miR-24-3p is unclear and controversial. We conducted this meta-analysis to evaluate the prognostic value of miR-24-3p in a variety of cancers by integrated existing articles from four databasesMethods: PubMed, Embase, Web of Science, and Cochrane Library (last update in March 2020) were searched for approach literature. Hazard ratios (HRs) and odds ratios (ORs) were used to evaluate the association between miR-24-3p expression levels and prognostic value or clinicopathological characteristics, respectively.Results: A total of 15 studies from 14 literature were finally qualified and concluded in the present meta-analysis. A significantly worse overall survival was observed in higher expression of miR-24-3p cancer group for OS(Overall survival) of log rank tests and cox multivariate regression by fixed effects model. Also, we found a significant correlation between elevated miR-24-3p levels to RFS (Recurrence-free survival) and DFS(Disease free survival). In addition, the pooled odds ratios (ORs) showed that evaluated miR-24-3p was also associated with the larger tumor size (≥5cm) and advanced TNM stage (Ⅲ and Ⅳ).Conclusion: Built on the above findings, elevated expression levels of miR-24-3p may serve as a promising biomarker used to predict the worse prognosis of cancer patients.

Introduction Sarcopenia has drawn considerable attention as a predictor of postoperative risk, although the relationship between sarcopenia and postoperative risk is contentious. This meta-analysis was conducted to evaluate this relationship. Methods A systematic literature search up to May 2020 was carried out and 43 studies were identified (with 16,716 patients) reporting on the relationship between sarcopenia and postoperative risk. In order to evaluate this relationship, odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using the dichotomous and continuous method with a random or fixed effects model. Results Compared with non-sarcopenic patients, those with sarcopenia have a higher major complications rate (OR: 4.03, 95% CI: 2.49–5.57, p<0.001), a higher total complications rate (OR: 1.77, 95% CI: 1.40–2.24, p<0.001), a higher 30-day mortality rate (OR: 2.38, 95% CI: 1.56–3.63, p<0.001) and a longer hospital stay (mean difference: 4.54 days, 95% CI: 2.49–6.59 days, p<0.001). Conclusions Sarcopenia significantly increases the risk of major complications, total complications, 30-day mortality and length of hospital stay. For this reason, it is recommended that sarcopenia is added to preoperative risk evaluation to avoid any possible negative outcomes following gastrointestinal oncological surgery.
