The Role of Chinese Medicine as a Complementary Therapy in the Management of Obesity-Associated Colorectal Cancer December 14, 2025
BACKGROUND: Colorectal cancer (CRC) has recently been identified as the world's third commonest cause of cancer death, accounting for 900,000 deaths per year. Obesity-related CRC has also been on the rise, with research indicating that increasing body mass index (BMI) is associated with an increased risk of CRC. As a result, there is a need […]

Cancer-Associated Cachexia in the Era of Obesity December 11, 2025
Obesity and cancer cachexia represent opposite ends of the body mass index (BMI) spectrum. However, despite this apparent dichotomy, both conditions share critical metabolic alterations, primarily driven by inflammation, metabolic alterations and changes in adipose tissue biology. Obesity is characterised by chronic low-grade inflammation and increased fat storage, while cancer cachexia involves severe weight loss, […]

Associations between obesity and outcomes in pembrolizumab-treated endometrial cancer December 11, 2025
CONCLUSIONS: In this diverse cohort, obesity was associated with worse PFS in patients treated with pembrolizumab for EC. MMRp tumors in obese patients had lowest response rates among subgroups. Further studies with long term follow up are needed to elucidate the biological mechanisms linking obesity to immunotherapy outcomes.

Unravelling the obesity paradox in cancer: An umbrella review of protective associations and evidence credibility across 13 malignancies December 3, 2025
CONCLUSIONS: Only 21 (14 %) meta-analyses provided convincing or highly suggestive evidence, demonstrating potential associations of obesity in specific oncological contexts pertaining to both reduced incidence risk and improved prognostic outcomes. This synthesis also highlights critical gaps in current evidence, emphasising the need for standardised adiposity metrics, more prudent stratification, and rigorous methodology.

Macrophages in obesity-related breast cancer: mechanistic insights and therapeutic opportunities November 28, 2025
Obesity has emerged as a global public health crisis, significantly increasing susceptibility to malignancies, including breast cancer. In the context of Obesity-Related Breast Cancer (ORBC), the abundant adipose tissue in the mammary gland profoundly reshapes the tumor microenvironment (TME). Whereas obesity drives chronic, low-grade inflammation through pro-inflammatory M1 adipose tissue macrophages (ATMs), tumor-associated macrophages (TAMs) […]

Effects of Helicobacter pylori infection on gastric cancer, obesity and esophageal diseases: a systematic review and meta-analysis November 27, 2025
CONCLUSION: H. pylori infection increases the risk of GC, H. pylori eradication is highly important for reducing the risk of GC. H. pylori infection was not associated with reduced risk of obesity and GERD, but the related evidence is limited and the mechanism is not clear. Based on the available evidence, decision-making for eradication treatment […]

Obesity as a Catalyst for Endometrial Hyperplasia and Cancer Progression: A Narrative Review of Epidemiology, Molecular Pathways, and Prevention November 27, 2025
Obesity is a major, modifiable driver of endometrial carcinogenesis. This review distills how excess adiposity promotes malignant change and synthesizes prevention strategies across the hyperplasia-cancer continuum. Three converging axes underpin risk: aromatase-mediated estrogen excess; insulin resistance with hyperinsulinemia activating PI3K-AKT-mTOR signaling; and adipokine-driven low-grade inflammation with downstream NF-κB/STAT3 activity. Within this framework, EIN is the […]

Obesity Paradox in Cancer: A Complex Interplay Between Risk and Therapeutic Outcomes November 21, 2025
Obesity is a recognized risk factor for cancer development and progression. Paradoxically, growing clinical evidence across several cancer types indicates that elevated body mass index (BMI) or specific body composition characteristics-such as increased visceral fat or preserved skeletal muscle-may be associated with moderately improved overall survival in patients undergoing immune checkpoint inhibitor (ICI) therapy. This […]

Overeating: A Conundrum of Lipid Metabolism and Inflammation in Obesity and Cancer October 28, 2025
The global rise in obesity has coincided with an alarming increase in early-onset cancers and other chronic noncommunicable diseases, underscoring the urgent need to understand the underlying mechanisms linking excess body weight with disease pathogenesis. While genetic factors account for disease risk, environmental and dietary influences, particularly those associated with Western hypercaloric diets, play a […]
