Evidence suggests that ejaculation frequency may be inversely related to the risk of prostate cancer (PCa), a disease for which few modifiable risk factors have been identified. ObjectiveTo incorporate an additional 10 yr of follow-up into an original analysis and to comprehensively evaluate the association between ejaculation frequency and PCa, accounting for screening, clinically relevant… Continue reading #Ejaculation Frequency and Risk of #Prostate Cancer: Updated Results with an Additional Decade of Follow-up

The #sulfur microbial diet is associated with increased risk of early-onset #colorectal cancer precursors
Diet may contribute to the increasing incidence of colorectal cancer (CRC) before age 50 (early-onset CRC). Microbial metabolism of dietary sulfur produces hydrogen sulfide (H2S), a gastrointestinal carcinogen that cannot be easily measured at scale. As a result, evidence supporting its role in early neoplasia is lacking. MethodsWe evaluated long-term adherence to the sulfur microbial… Continue reading The #sulfur microbial diet is associated with increased risk of early-onset #colorectal cancer precursors
#EGFR activation limits the response of #liver cancer to lenvatinib
Hepatocellular carcinoma (HCC)—the most common form of liver cancer—is an aggressive malignancy with few effective treatment options1. Lenvatinib is a small-molecule inhibitor of multiple receptor tyrosine kinases that is used for the treatment of patients with advanced HCC, but this drug has only limited clinical benefit2. Here, using a kinome-centred CRISPR–Cas9 genetic screen, we show… Continue reading #EGFR activation limits the response of #liver cancer to lenvatinib
Effects of #Tamoxifen vs. Toremifene on #fatty liver development and lipid profiles in #breast Cancer
Tamoxifen (TAM) and Toremifene (TOR), two kinds of selective estrogen receptor modulators (SERMs), have equal efficacy in breast cancer patients. However, TAM has been proved to affect serum lipid profiles and cause fatty liver disease. The study aimed to compare the effects of TAM and TOR on fatty liver development and lipid profiles. MethodsThis study… Continue reading Effects of #Tamoxifen vs. Toremifene on #fatty liver development and lipid profiles in #breast Cancer
SO-25 Global rise in early-onset #colorectal cancer: An association with #antibiotic consumption?
Since the late 1980s, global antibiotic consumption and colorectal cancer (CRC) rates in those aged less than 50 years have soared. As the gut microbiome modulates many human processes, significantly altering microbiome structure and diversity with antibiotic therapy has previously been shown to influence CRC genesis in older adults. To our knowledge, no study before… Continue reading SO-25 Global rise in early-onset #colorectal cancer: An association with #antibiotic consumption?
#Proton pump inhibitors and risk of #colorectal cancer
To determine whether proton pump inhibitors (PPIs) are associated with an increased risk of colorectal cancer, compared with histamine-2 receptor antagonists (H2RAs). Design The United Kingdom Clinical Practice Research Datalink was used to identify initiators of PPIs and H2RA from 1990 to 2018, with follow-up until 2019. Cox proportional hazards models were fit to estimate… Continue reading #Proton pump inhibitors and risk of #colorectal cancer
Peroxidation of n-3 and n-6 polyunsaturated #fatty acids in the acidic #tumor environment leads to ferroptosis-mediated anticancer effects
Highlights•n-3 and n-6 PUFAs preferentially accumulate in lipid droplets of acidic cancer cells •Excess LC-PUFAs undergo peroxidation and induce ferroptosis in acidic cancer cells •DGAT inhibitors prevent the formation of lipid droplets and promote ferroptosis •DGATi enhance the tumor growth inhibitory effects of dietary n-3 LC-PUFAs in mice SummaryTumor acidosis promotes disease progression through a… Continue reading Peroxidation of n-3 and n-6 polyunsaturated #fatty acids in the acidic #tumor environment leads to ferroptosis-mediated anticancer effects
#Mirtazapine in cancer-associated #anorexia and #cachexia: A double-blind placebo-controlled randomized trial
Few pharmacological interventions are available for cancer-associated anorexia and cachexia. Mirtazapine has been suggested for use in cancer-associated anorexia and cachexia. ObjectivesThis study was conducted to assess the efficacy and tolerability of mirtazapine in cancer-associated anorexia and cachexia. MethodsA double-blind placebo-controlled randomized trial. The study included 120 incurable solid tumour patients with anorexia (appetite loss… Continue reading #Mirtazapine in cancer-associated #anorexia and #cachexia: A double-blind placebo-controlled randomized trial
#Thyroid dysfunction and #breast cancer risk among women in the UK Biobank cohort
This study aimed to evaluate the association between thyroid dysfunction and breast cancer risk. We included 239,436 females of the UK Biobank cohort. Information on thyroid dysfunction, personal and family medical history, medications, reproductive factors, lifestyle, and socioeconomic characteristics was retrieved from baseline self-reported data and hospital inpatient databases. Breast cancer diagnoses were identified through… Continue reading #Thyroid dysfunction and #breast cancer risk among women in the UK Biobank cohort
