Article Abstract
Background: A host of studies show Leptin (LEP) G19A polymorphism is correlated with the risk of various cancers, but the connection of this polymorphism with bladder cancer (BC) risk has not been reported.
Materials And Methods: This association was in explored in a case-control study involving 355 BC cases and 435 controls (all Chinese Han). Polymerase chain reaction-restriction fragment length polymorphism was conducted to genotype LEP G19A polymorphism. Analyses of allele and genotype distribution were evaluated using chi-square test. Continuous data were assessed by an independent samples t test or one-way ANOVA test. Odds ratio (OR) and 95% confidence interval (CI) were determined by logistic regression.
Results: LEP G19A polymorphism was significantly associated with a lower risk of BC (AA vs GG: adjusted OR, 0.40, 95% CI, 0.20-0.83, P = .013; AA + GA vs GG: adjusted OR, 0.70, 95% CI, 0.52-0.93, P = .015; AA vs GA + GG: adjusted OR, 0.45, 95% CI, 0.22-0.91, P = .026). In addition, A allele was associated with decreased risk for BC (A vs G: OR, 0.70, 95% CI, 0.55-0.89, P = .003). Stratified analyses by females, non-drinkers, and non-smokers all returned considerable relations. Furthermore, LEP G19A polymorphism was correlated with tumor size, tumor node metastasis, and distant metastasis in BC patients.
Conclusions: LEP G19A polymorphism is associated with a less risk of BC.

Background And Aims: There is a link between genetics with metabolic balance and adiposity homeostasis on metabolic syndrome (MetS). Polymorphism in adipokine genes such as leptin and adiponectin may play an important role in its development. This study aimed to determine the association of the individual and general components of MetS with genetic alterations in LEP (rs7799039 and rs2167270) and ADIPOQ (rs1501299 and rs2241766) genes in the Mexican population.

Background: Although the effect of the LEP G19A (rs2167270) polymorphism on cancers is assumed, the results of its influence have been contradictory. A meta-analysis was conducted to precisely verify the relationships between LEP G19A and the development of digestion-related cancers.
Methods: Investigators systematically searched the literature in PubMed, Embase, and Web of Science and used STATA software 14.

Background: A host of studies have explored the potential connection between () G19A polymorphism and the risk of cancers, but the relationship between gastric cancer (GC) susceptibility and G19A polymorphism was not revealed before. The aim of this study was to investigate this relationship in Chinese Han population.
Methods: Thus, this case-control study with 380 GC cases and 465 controls was designed to unearth the link between G19A polymorphism and GC susceptibility.

Accumulating evidence has suggested that leptin (LEP) is very important for the development of cancer. Recently, a number of case-control studies about the relationship of the rs2167270 G > A (G19A) variants in the LEP gene with the risk of cancer have yielded inconsistent results. In this study, we have carried out a case-control study [1063 esophagogastric junction adenocarcinoma (EGJA) cases and 1677 controls] in a Chinese population.
