Background: CD44 has recently been reported as a biomarker for pancreatic cancer. However, the predictive value of CD44 in pancreatic cancer remains controversial. Therefore, we performed this meta-analysis to evaluate the association between the expression of CD44 and clinicopathological features, and the outcome of pancreatic cancer patients. Materials and method: A comprehensive literature search was performed using PubMed, Embase, and Chinese National Knowledge Infrastructure. The statistical analysis was conducted using Stata software. Results: A total of nine studies including 583 cases were included in this meta-analysis. The meta-analysis indicated that CD44 overexpression was associated with poor five-year overall survival rate (OR 0.52; 95% CI 0.30, 0.91; P = 0.02), more lymph node invasion (OR 3.14 (positive vs. negative); 95% CI 1.47, 6.73; P = 0.003), more advanced T stage (OR 2.4 (T3,4 vs. T1,2); 95% CI 1.28, 4.52; P = 0.007), and more advanced TNM stage (OR 4.53 (III~IV vs. I~II); 95% CI 1.46, 14.08; P = 0.01). However, CD44 overexpression was not associated with other clinicopathological features, such as tumor size, differentiation, and distance metastasis. Conclusions: The current evidence suggests that CD44 is an efficient prognostic factor in pancreatic cancer.

Abstract Background The importance of breastfeeding for maternal and child health has become an international consensus. However, it has been found that lactation-related nipple problems are common and there are some important factors affecting the effectiveness of breastfeeding. Multiple studies recommended the laid-back breastfeeding, but the researches are on various levels of quality and the results are controversial.Methods We systematically searched the following twelve databases: Cochrane Library, EMBASE, Medline, Ovid, PubMed, Web of Science, CINAHL, Scopus, SinoMed, Chinese National Knowledge Infrastructure (CNKI), WanFang, and VIP from inception to January 28,2020. All studies reporting the laid-back breastfeeding or biological nurturing were considered, regardless of they are randomized controlled trials. Two trained investigators independently evaluated the quality of the included the articles and screened the data. All the data were analyzed separately using Review Manager Version 5.3 and STATA/SE Version 15.1. Results A total of 12 studies involving 1,936 groups of postpartum women and their newborns were included. The results of meta-analysis showed that nipple trauma (RR = 0.47; 95% CI 0.29,0.75; p < 0.002), nipple pain (RR = 0.25; 95% CI 0.20,0.32; p < 0.00001), the correct posture of latching (RR = 1.22; 95% CI 1.11,1.33; p < 0.00001)and position comfort (ES = 0.01; 95%CI -0.28,0.30; p = 0.006) of experimental group were all better than control group, and the differences were statistically significant ( p < 0.05), which indicates that the laid-back position has a positive effect on maternal breastfeeding. Conclusion Laid-back position has significant advantages in decreasing the incidence of nipple trauma and nipple pain compared with traditional breastfeeding postures, and it appears that laid-back position is conducive to the correct posture of latching. However, current evidence does not show different breastfeeding outcomes in the two groups of position comfort. Laid-back position is helpful to solve lactation-related nipple problems and it can be used as a recommended position for breastfeeding.

AbstractMiR-19a was aberrantly expressed in various types of cancers and was observed to be potentially associated with the prognosis of cancer patients. The present analysis aims to elucidate its precise predictive value in various human malignancies. Online electronic searches of PubMed, Web of Science (WOS), Embase in English and VIP, Wanfang, SinoMed, and the China National Knowledge Infrastructure (CNKI) in Chinese up to September 8, 2018 were conducted. As a result, in overall analysis, a significant association was identified between miR-19a levels and OS (HRs = 2.31, CI: 1.11–4.83). The relation of miR-19a expression to OS was further recognized by fixed model within the studies of sample size less than 150 (HRs = 1.68, CI: 1.35–2.08), NOS scores greater than or equal to 8 (HRs = 1.53, CI: 1.13–2.06) or less than 8 (HRs = 1.89, CI: 1.58–2.27), specimen derived from tumor (HRs = 1.73, CI: 1.42–2.12) or blood (HRs = 1.87, CI: 1.46–2.40) and the patients of osteosarcoma (HRs = 7.17, CI: 5.04–10.21). Sensitivity analyses revealed no significant results. The association between miR-19a expression level and DFS was also found to be significant (HRs = 2.03, CI: 1.13–3.66). Correlations between miR-19a levels and clinicopathological features were examined and revealed that lymph node metastasis was significantly associated with miR-19a expression levels (OR = 0.565, CI: 0.346–0.921). Summarily, the over expression of miR-19a was an underlying risk of poor prognosis in many human malignancies, especially in osteosarcoma. Moreover, elevated miR-19a expression was linked to the potential of lymph node metastasis.

Background.The small Ca2+-binding protein S100A4 is identified as a metastasis-associated or metastasis-inducing protein in various types of cancer. The goal of this meta-analysis was to evaluate the relationship between S100A4 expression and clinicopathological characteristics and prognosis of patients with pancreatic cancer.Methods. A comprehensive literature search was carried out in the electronic databases PubMed and Chinese CNKI. Only the studies reporting the correlation between S100A4 expression and clinicopathological characteristics or overall survival (OS) of patients with pancreatic cancer are enrolled. Extracted data was analyzed using the RevMan 5.3 software to calculate the pooled relative risks (95% confidence interval, CI) for statistical analyses.Results.Seven studies including a total of 474 patients were enrolled into this meta-analysis. Negative expression of S100A4 was significantly associated with higher 3-year OS rate (RR = 3.92, 95% CI = 2.24–6.87,P<0.0001), compared to S100A4-positive cases. Moreover, negative expression of S100A4 was also related to N0 stage for lymph node metastasis (RR = 2.15, 95% CI = 1.60–2.88,P<0.0001). However, S100A4 expression was not significantly correlated with histological types and distant metastasis status.Conclusion.S100A4 expression represents a potential marker for lymph node metastasis of pancreatic cancer and a potential unfavorable factor for prognosis of patients with this disease.

Background/Aims: Secreted protein acidic and rich in cysteines-like 1 (SPARCL1) is abnormally expressed in gastrointestinal (GI) malignancies. However, the correlation between SPARCL1 expression and the prognosis of patients remains unknown. Therefore, we performed a meta-analysis to investigate the potential value of SPARCL1 as a prognostic predictive marker for GI malignancies. Methods: The PubMed, Embase, EBSCO, CNKI, and Wanfang databases were systematically searched for studies examining SPARCL1 and clinicopathological features, including the prognoses of patients. Hazard ratios (HRs) and odds ratios (ORs) from individual studies were calculated and pooled using a random-effects or fix-effects model. Heterogeneity and publication bias analyses were performed. Results: Data from 8 studies, including a total of 2,356 patients, were summarized. The expression of SPARCL1 suggested a better prognosis (HR=0.57, 95% CI: 0.445-0.698, P=0.000) and was associated with clinicopathological features of GI malignancies, including distant metastasis (OR=0.44, 95% CI: 0.23-0.85, P=0.014), lymph node metastasis (OR=0.56, 95% CI: 0.39–0.81, P=0.002) and tumor differentiation (OR=2.21, 95% CI: 1.82–2.69, P=0.000). Subgroup analyses based on cancer type revealed that the expression of SPARCL1 had no effect on lymph node metastasis in colorectal cancer, and it did not influence tumor differentiation in gastric cancer. Egger’s test showed no evidence of publication bias (all P>0.05). Conclusion: SPARCL1 could be a novel prognostic predictive factor for GI malignancies. The expression of SPARCL1 could influence the clinicopathological features of GI malignancies. Further large-scale studies are essential to confirm SPARCL1’s prognostic predictive value, and more fundamental experimental studies are needed to illustrate the mechanisms.

Abstract Background Approximately 5.0–24.2% of colorectal cancers (CRCs) have inactivating mutations in SMAD4, making it one of the frequently mutated genes in CRC. We thus carried out a comprehensive system review and meta-analysis investigating the prognostic significance and clinicopathological features of SMAD4 gene mutation in CRC patients. Methods A detailed literature search was conducted in PubMed, Web of Science and Embase databases to study the relationship between SMAD4 mutations and the demographic and clinicopathological characteristics in CRC patients. The hazard ratios (HRs) with 95% confidence intervals (CI) were used to evaluate the effect of SMAD4 mutations on overall survival (OS) and progression-free survival (PFS)/recurrence-free survival (RFS). Results Ten studies enrolling 4394 patients were eligible for inclusion. Data on OS were available from 5 studies and data on PFS/RFS were available from 3 studies. Comparing SMAD4-mutated CRC patients with SMAD4 wild-type CRC patients, the summary HR for OS was 1.46 (95% CI 1.28–1.67, P = 0.001), the summary HR for PFS/RFS was 1.59 (95% CI 1.14–2.22, P = 0.006). In terms of clinicopathology parameters, 9 studies have data that can be extracted, SMAD4 mutations were associated with tumor location (odds ratio [OR] = 1.15, colon/rectum, 95% CI 1.01–1.31, P = 0.042), TNM stage (OR = 1.28, stage IV/I–III, 95% CI 1.03–1.58, P = 0.025), lymph node metastasis (OR = 1.42, N1 + N2/N0, 95% CI 1.20–1.67, P < 0.001), mucinous differentiation (OR = 2.23, 95% CI 1.85–2.70, P < 0.001) and rat sarcoma viral oncogene homolog (RAS) mutation status (OR = 2.13, 95% CI 1.37–3.34, P = 0.001). No connection was found with age, gender, tumor grade, microsatellite instability status and b-viral oncogene homolog B1 mutation status. Besides, publication bias was not observed in any study. Conclusions This meta-analysis suggests that SMAD4 mutation was associated with OS, PFS/RFS, and clinicopathological parameters, including tumor site, disease stage, RAS status, lymph node metastasis and mucinous differentiation. Our meta-analysis indicated that SMAD4 mutations could predict the poor prognosis and aggressive clinicopathological characteristics of CRC. More large-sample cohort studies are needed to confirm this conclusion. Since SMAD4 mutations are closely related to RAS mutations, their relationship warrants further investigation.

Abstract Background: Long noncoding RNA associated with poor prognosis of hepatocellular carcinoma (AWPPH) is a novel oncogene and dysregulated in a variety of human cancers. It has been revealed to be associated with the clinicopathological features and prognosis. However, the prognostic value of AWPPH in various cancers remains unclear. Therefore, we perform this meta-analysis to evaluate the relationship between AWPPH expression and clinical outcomes in human cancers.Methods: Comprehensive literature search was performed in PubMed, Web of Science, CNKI and Wangfang databases, and eligible studies were obtained according to the inclusion and exclusion criteria. The pooled hazard ratios (HRs) and odds ratios (ORs) were applied to assess the clinical value of AWPPH expression for overall survival (OS) and clinicopathological features.Results: A total of 19 articles including 1699 cancer patients were included in the study. The pooled results demonstrated that evaluated AWPPH expression was positively related to a poorer overall survival of patients with cancers (HR=1.79, 95%CI: 1.44-2.14, P<0.001). Subgroup analysis revealed that tumor type and sample size affect the predictive value of AWPPH on OS, whereas cut-off value and HR estimation method have no impact on it. In addition, the pooled data also showed that AWPPH was positively linked to advanced TNM stage (OR=2.67, 95%CI: 1.86-3.83, P<0.001) , bigger tumor size (OR=2.64, 95%CI:1.47-4.73, P=0.001), macro-vascular invasion (OR=2.08, 95%CI: 1.04-4.16, P=0.04) and lymph node metastasis (OR=2.68, 95%CI: 1.82-3.96, P<0.001). Moreover, the results of the trim and fill analysis confirmed the reliability of our finding. Conclusions: Upregulation of AWPPH was associated with advanced TNM stage, bigger tumor size, worse lymph node metastasis, macro-vascular invasion, and shorter overall survival, suggesting that AWPPH may serve as a biomarker for prognosis and clinicopathological characteristics in human cancers.
