Special Issue Information

Dear Colleagues,

We are pleased to invite you to submit articles focused on molecular, pharmacologic, hormonal, immunologic, microbiologic, genetic and epigenetic mechanisms, and modulators alone and/or in combination with lifestyle or metabolic-bariatric surgical interventions to disrupt the obesity cancer linkage. In this Special Issue, original research articles and reviews are welcome.

Overweight and obesity constitute a major worldwide pandemic affecting over 2 billion individuals. They are causally related to significant comorbidities, including the promotion, acceleration, and worsening of the prognosis of multiple malignancies. Obesity is estimated to be associated with 20% cancer deaths in women and 14% in men. Many consequences of obesity have been shown to promote the obesity cancer linkage, including inflammatory, metabolic, and hormonal processes, mediated by adipokines, cytokines, hormones, microbiome dysbiosis, and epigenetic changes. Intentional weight loss strategies, including intensive lifestyle alterations and/or metabolic-bariatric surgery, clearly ameliorate some of the metabolic effects of obesity, but only show modest benefits in terms of decreasing cancer incidence and/or reducing cancer-related mortality.

This Special Issue of Cancers aims to more precisely define obesity cancer linkages; more specifically identify the mechanisms by which obesity-associated cancer-promoting processes actually mediate their effects; and to focus on identifying strategies, agents, and interventions which alone and/or in combination will disrupt the obesity cancer linkage.

I look forward to receiving your contributions.

Prof. Dr. Nathan Berger

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cancers is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

This study aimed to investigate the risk of gastric cancer (GC) in abnormal body mass index (BMI) groups. A systematic search was carried out on Embase, PubMed/Medline, and Scopus from January 2000 to January 2023. The pooled risk ratio (RR) with a 95% confidence interval (CI) was assessed using a random-effect model. Thirteen studies with total of 14,020,031 participants were included in this systematic review. The pooled RR of GC was 1.124 (95% CI, 0.968–1.304, I2: 89.08%) in underweight class, 1.155 (95% CI, 1.051–1.270, I2: 95.18%) in overweight class, and in 1.218 (95% CI, 1.070–1.386, I2: 97.65%) obesity class. There is no difference between cardia and non-cardia gastric cancer, while non-Asian race and female gender have higher risk of cancer, as Meta-regression of obesity and overweight classes showed. These findings suggest that there is a positive association between excess body weight and the risk of GC, with a higher impact in women than men and in non-Asian than Asian populations. Since abnormal weight is tied to various diseases, including GC, healthcare experts, and policymakers should continue interventions aiming to achieve a normal BMI range. Full article
