The Relationship

Objectives We investigated the association between the consumption of fresh and processed fish and glioma risk using a meta-analysis approach. Methods We selected and analyzed observational studies that discussed the relationships between fresh and processed fish intake on glioma risk from PubMed, Web of Science, Embase, and the SinoMed and Wanfang databases from inception to 31 March 2020. Studies were selected according to pre-established eligibility criteria and data were extracted separately by two researchers. A meta-analysis was conducted based on a random-effects model to provide pooled odds ratios (OR) and 95% confidence intervals (CIs). Results Eight studies considered the relationship between fish intake (seven fresh and seven processed fish) and glioma risk and were included in this meta-analysis. The OR effect size for fresh fish intake and glioma risk was 0.72 (95%CI 0.53–0.97) and the overall OR effect size for processed fish intake and glioma risk was 1.88 (95%CI 1.06–3.34). Conclusion Dietary intake of fresh fish may reduce the risk of glioma, but consumption of processed fish may increase the risk of glioma. This study had some limitations, and further studies are therefore required to clarify the associations between fish intake and glioma risk.

ABSTRACT Limited data are available that summarize the relation between egg intake and the risk of upper aero-digestive tract (UADT) cancers. This systematic review and meta-analysis was conducted to investigate the association between egg intake and the risk of UADT cancers. Medline/PubMed, ISI web of knowledge, EMBASE, Scopus, and Google Scholar were searched using relevant keywords. Observational studies conducted on humans investigating the association between egg consumption and the risk of UADT cancers were included. Overall, 38 studies with a total of 164,241 subjects (27, 025 cases) were included. Based on 40 effect sizes from 32 case-control studies, we found a 42% increased risk of UADT cancers among those with the highest egg consumption (ranging from ≥1 meal/d to ≥1 time/mo among studies) compared to those with the lowest intake (ranging from 0–20 g/d to never consumed among studies) (overall OR: 1.42; 95% CI: 1.19, 1.68; P < 0.001). However, this association was only evident in hospital-based case-control (HCC) studies (OR = 1.50; 95% CI: 1.34, 1.68; P < 0.001 for ‘oropharyngeal and laryngeal cancer’ and OR: 1.27; 95% CI: 1.08, 1.50; P = 0.004 for esophageal cancer) and not in population-based case-control (PCC) studies (OR = 1.25; 95% CI: 0.59, 2.67; P = 0.56 for ‘oropharyngeal and laryngeal cancer’ and OR: 1.29; 95% CI: 0.92, 1.81; P = 0.13 for esophageal cancer). In addition, the association was not significant in prospective cohort studies (overall OR: 0.86; 95% CI: 0.71, 1.04; P = 0.11). Considering individual cancers, a positive association was observed between the highest egg consumption, compared with the lowest, and risk of oropharyngeal (OR: 1.88; 95% CI: 1.61, 2.20; P < 0.001), laryngeal (OR: 1.83; 95% CI: 1.45, 2.32; P < 0.001), oral & pharyngeal & laryngeal (OR: 1.37; 95% CI: 1.12, 1.67; P < 0.001), and esophageal cancers (OR: 1.28; 95% CI: 1.10,1.48; P = 0.001). We also found an inverse association between egg intake and the risk of oral cancer (OR: 0.78; 95% CI: 0.62, 0.99; P = 0.04). In conclusion, high egg consumption (ranging from ≥1 meal/d to ≥1 time/mo among studies) was associated with increased risk of UADT cancers only in HCC studies but not in PCC or prospective cohort studies.

20 Background: Obesity influences incidence of esophageal cancer (EC) with contrasting impact on esophageal adenocarcinoma (EAC) and esophageal squamous cell carcinoma (ESC). However, it is unclear whether it influences mortality in patients with EC. We performed a systematic review and meta-analysis to assess the association between obesity and EC mortality. Methods: Through a systematic search of major databases and conference proceedings, up to June 2015, we identified observational studies reporting the association between obesity (premorbid body mass index [BMI] ≥ 30 kg/m2) and all-cause mortality in patients with EC. We estimated summary adjusted hazard ratio (aHR) with 95% confidence intervals (CI), comparing highest BMI category with reference category in each study using random effects model; heterogeneity was measured using the inconsistency index (I2). Results: We identified 8 studies (including 1 pooled cohort study) with 2,784,027 people, of whom 18% were obese. On meta-analysis, compared with EC patients with reference BMI, obese EC patients had aHR for mortality of 0.97 (95% CI, 0.66-1.43), with high heterogeneity (I2 = 88%) after pooling maximally adjusted HRs. On analyzing patients with EAC alone (3 studies), mortality aHR was 1.10 (95% CI, 0.43-2.82), with high heterogeneity (I2 = 95%). Data to separately analyze ESC or to perform subgroup analysis in males vs females, smokers vs never smokers and Asia Pacific vs Western populations was limited. Conclusions: Based on meta-analysis, obesity does not appear to be associated with mortality in patients with EC. However, high heterogeneity and limited data for subgroup analysis limits the interpretation of this analysis. Further prospective studies evaluating mortality in patients with established EC are needed to answer this question. [Table: see text]

Salt Consumption

Abstract Context Evidence has shown that essential nutrients are highly correlated with the occurrence of esophageal cancer (EC). However, findings from observational studies on the associations between dietary carbohydrate, salt consumption, and the risk of EC remain controversial. Objective The aim of this study was to conduct a systematic review and meta-analysis to confirm the associations of dietary carbohydrate and salt consumption with EC risk. Data Source Various electronic databases (PubMed, MEDLINE, Embase, Google Scholar, Cochrane Library, Chinese Electronic Periodical Services, and China Knowledge Resource Integrated) were searched up until January 31, 2019. Data Extraction Data related to patient characteristics and study characteristics were extracted by 2 independent reviewers. The risk ratio reported as relative risk (RR) or odds ratio (OR) was extracted, and random-effects models were performed to estimate the summary risk ratio. Results In total, 26 studies were included in this analysis, of which 12 studies, including 11 case-control studies and 1 cohort study, examined dietary carbohydrates, and 18 studies, including 16 case-control studies and 2 cohort studies, examined dietary salt. The pooled OR showed that dietary carbohydrate intake was inversely related to EC risk (OR = 0.62; 95% confidence interval [CI], 0.50–0.77), but positive correlations between dietary salt intake and the risk of EC were supported by the recruited case-control studies (OR = 1.97; 95% CI, 1.50–2.61) and cohort studies (RR = 1.04; 95% CI, 1.00–1.08). Conclusions Salt is an essential nutrient for body functions and biochemical processes. Providing health education and management regarding proper use of salt in daily foods and labeling the amount of sodium in manufactured products to reduce the risk of developing EC should be more appropriately performed in the general population.
