AbstractTo evaluate the effect of vitamin D3 supplementation on cancer mortality in the general population and on prognosis in cancer patients, a systematic review and meta-analysis of randomised, placebo-controlled trials (RCTs) and individual patient data (IPD) was conducted. Overall, 14 RCTs with a total of 104,727 participants (2015 cancer deaths) were identified and 7 RCTs, including… Continue reading Efficacy of vitamin D3 supplementation on cancer mortality: Systematic review and individual patient data meta-analysis of randomised controlled trials

Analysis of Body Mass Index in Early and Middle Adulthood and Estimated Risk of Gastrointestinal Cancer
Importance In a population with significantly increasing rates of individuals with overweight or obesity, understanding the association of obesity with long-term disease risk, such as cancer, is necessary to improve public health.Objective To investigate the association between body mass index (BMI) and gastrointestinal (GI) cancer risk (colorectal cancer [CRC] and noncolorectal GI cancer) in the Prostate, Lung,… Continue reading Analysis of Body Mass Index in Early and Middle Adulthood and Estimated Risk of Gastrointestinal Cancer
Fifteen-Year Outcomes after Monitoring, Surgery, or Radiotherapy for Prostate Cancer
BACKGROUNDBetween 1999 and 2009 in the United Kingdom, 82,429 men between 50 and 69 years of age received a prostate-specific antigen (PSA) test. Localized prostate cancer was diagnosed in 2664 men. Of these men, 1643 were enrolled in a trial to evaluate the effectiveness of treatments, with 545 randomly assigned to receive active monitoring, 553… Continue reading Fifteen-Year Outcomes after Monitoring, Surgery, or Radiotherapy for Prostate Cancer
Ultra-processed food consumption, cancer risk and cancer mortality: a large-scale prospective analysis within the UK Biobank
Global dietary patterns are increasingly dominated by relatively cheap, highly palatable, and ready-to-eat ultra-processed foods (UPFs). However, prospective evidence is limited on cancer development and mortality in relation to UPF consumption. This study examines associations between UPF consumption and risk of cancer and associated mortality for 34 site-specific cancers in a large cohort of British… Continue reading Ultra-processed food consumption, cancer risk and cancer mortality: a large-scale prospective analysis within the UK Biobank
Efficacy of low-dose oral minoxidil in the management of anticancer therapy-induced alopecia in patients with breast cancer: A retrospective cohort study
To the Editor: Alopecia is feared by most patients undergoing systemic anticancer therapy for breast cancer because of its negative impact on quality of life.1 Currently, evidence regarding management of persistent chemotherapy-induced alopecia ( pCIA) and endocrine therapy-induced alopecia (EIA) in patients with breast cancer is lacking.2-4 Although previous studies demonstrated successful use of lowdose… Continue reading Efficacy of low-dose oral minoxidil in the management of anticancer therapy-induced alopecia in patients with breast cancer: A retrospective cohort study
Dysregulated amino acid sensing drives colorectal cancer growth and metabolic reprogramming leading to chemoresistance
Background and AimsCRC is a devastating disease highly modulated by dietary nutrients. mTORC1 contributes to tumor growth and limits therapy responses. Growth factor signaling is a major mechanism of mTORC1 activation. However, compensatory pathways exist to sustain mTORC1 activity following therapies that target oncogenic growth factor signaling. Amino acids potently activate mTORC1 via amino acid… Continue reading Dysregulated amino acid sensing drives colorectal cancer growth and metabolic reprogramming leading to chemoresistance
An Exercise-Induced Metabolic Shield in Distant Organs Blocks Cancer Progression and Metastatic Dissemination
Exercise prevents cancer incidence and recurrence, yet the underlying mechanism behind this relationship remains mostly unknown. Here we report that exercise induces the metabolic reprogramming of internal organs that increases nutrient demand and protects against metastatic colonization by limiting nutrient availability to the tumor, generating an exercise-induced metabolic shield. Proteomic and ex vivo metabolic capacity analyses of… Continue reading An Exercise-Induced Metabolic Shield in Distant Organs Blocks Cancer Progression and Metastatic Dissemination
Ovarian cancer cell fate regulation by the dynamics between saturated and unsaturated fatty acids
SignificanceUnsaturated fatty acids are critical for maintaining membrane fluidity, cellular signaling, and lipid storage. Stearoyl-CoA desaturase (SCD) regulates the dynamics between saturated and unsaturated fatty acids. How SCD is involved in cancer cell fate decisions remains incompletely understood. Here, we leveraged transcriptomics, lipidomics, and single-cell stimulated Raman scattering microscopy to show that increased levels of… Continue reading Ovarian cancer cell fate regulation by the dynamics between saturated and unsaturated fatty acids
Arid1a mutation suppresses TGF-β signaling and induces cholangiocarcinoma
Activating KRAS mutations and functional loss of members of the SWI/SNF complex, including ARID1A, are found together in the primary liver tumor cholangiocarcinoma (CC). How these mutations cooperate to promote CC has not been established. Using murine models of hepatocyte and biliary-specific lineage tracing, we show that Kras and Arid1a mutations drive the formation of CC and tumor precursors from the biliary compartment,… Continue reading Arid1a mutation suppresses TGF-β signaling and induces cholangiocarcinoma
