Fructose consumption has increased considerably over the past five decades, largely due to the widespread use of high-fructose corn syrup as a sweetener1. It has been proposed that fructose promotes the growth of some tumours directly by serving as a fuel2,3. Here we show that fructose supplementation enhances tumour growth in animal models of melanoma,… Continue reading Dietary #fructose enhances #tumour growth indirectly via interorgan lipid transfer

Associations of plasma omega-6 and omega-3 #fatty acids with overall and 19 site-specific #cancers: A population-based cohort study in UK Biobank
AbstractPrevious epidemiological studies on the associations between polyunsaturated fatty acids (PUFAs) and cancer incidence have been inconsistent. We investigated the associations of plasma omega-3 and omega-6 PUFAs with the incidence of overall and 19 site-specific cancers in a large prospective cohort. 253,138 eligible UK Biobank participants were included in our study. With a mean follow-up… Continue reading Associations of plasma omega-6 and omega-3 #fatty acids with overall and 19 site-specific #cancers: A population-based cohort study in UK Biobank
Dietary pro-oxidant therapy by a vitamin #K precursor targets PI 3-kinase VPS34 function
In light of emerging evidence that antioxidants can have cancer-promoting effects, Swamynathan et al. tested potential pro-oxidant interventions (see the Perspective by Pannia and Dowling). In particular, the authors focused on menadione sodium bisulfite, a water-soluble precursor of vitamin K. As the authors anticipated, this menadione derivative suppressed prostate cancer growth. The researchers then examined… Continue reading Dietary pro-oxidant therapy by a vitamin #K precursor targets PI 3-kinase VPS34 function
#Aspirin Use and Incidence of #Colorectal Cancer According to Lifestyle Risk
Importance Aspirin reduces the risk of colorectal cancer (CRC). Identifying individuals more likely to benefit from regular aspirin use for CRC prevention is a high priority.Objective To assess whether aspirin use is associated with the risk of CRC across different lifestyle risk factors.Design, Setting, and Participants A prospective cohort study among women in the Nurses’ Health Study (1980-2018)… Continue reading #Aspirin Use and Incidence of #Colorectal Cancer According to Lifestyle Risk
Deep learning assists detection of #esophageal #cancer and precursor lesions in a prospective, randomized controlled study
Early-stage esophageal cancers show better treatment response but are harder to detect. Li et al. developed a deep learning pipeline to aid clinicians in identifying early-stage, high-risk esophageal lesions and tested it in a randomized clinical trial in patients undergoing endoscopy. Deep learning assistance doubled the detection of high-risk esophageal lesions compared with the unassisted control group.… Continue reading Deep learning assists detection of #esophageal #cancer and precursor lesions in a prospective, randomized controlled study
Bilateral #Mastectomy and #Breast Cancer Mortality
Question Does bilateral mastectomy for treatment of unilateral breast cancer reduce the 20-year risk of breast cancer mortality?Findings This cohort study including 661 270 women with unilateral breast cancer who were closely matched by treatment type (lumpectomy, unilateral mastectomy, or bilateral mastectomy) and followed up for 20 years found that bilateral mastectomy was associated with a statistically significant… Continue reading Bilateral #Mastectomy and #Breast Cancer Mortality
Comprehensive assessment of #pesticide use patterns and increased #cancer risk
Pesticides are an essential feature of modern-day agriculture that adds to the list of factors that increase cancer risk. Our study aims to comprehensively evaluate this relationship through a population-based approach that considers confounding variables such as county-specific rates of smoking, socioeconomic vulnerability, and agricultural land. We achieved our goal with the implementation of latent-class… Continue reading Comprehensive assessment of #pesticide use patterns and increased #cancer risk
#Urticaria and the risk of #cancer: a Danish population-based cohort study
BackgroundUrticaria has been tentatively linked to cancer, but epidemiological evidence supporting this link is sparse and conflicting. We therefore conducted a population-based cohort study using healthcare databases of the Danish population (January 1980–December 2022). We followed 87,507 people for a median of 10.1 years after first hospital contact for urticaria.ObjectivesTo examine associations of a hospital… Continue reading #Urticaria and the risk of #cancer: a Danish population-based cohort study
#Virtual reality for #pain management in hospitalized patients with #cancer: A randomized controlled trial
Hospitalized patients with cancer often experience acute and/or chronic pain. Although virtual reality (VR) has been extensively studied across a wide range of clinical settings, no studies have yet evaluated potential impact on pain management in this patient population.MethodsProspective randomized controlled trial at an urban academic hospital comparing VR against an active control to mitigate… Continue reading #Virtual reality for #pain management in hospitalized patients with #cancer: A randomized controlled trial
