AbstractThe COVID-19 vaccine is a significant technological advancement with widespread global use. However, its effect on cancer immunity, particularly with repeated vac-cinations, remains unclear. We aimed to investigate the relationship between repeated vaccinations and pancreatic cancer (PC) prognosis. Additionally, we examined serum IgG4 levels, known to be an immune suppressor and increased with repeated vac-cinations.… Continue reading Repeated #COVID-19 #Vaccination as a Poor Prognostic Factor in Pancreatic #Cancer: A Retrospective, Single-Center Cohort Study

#Dietary fibre counters the oncogenic potential of colibactin-producing Escherichia coli in colorectal #cancer
Diet, microbiome, inflammation and host genetics have been linked to colorectal cancer development; however, it is not clear whether and how these factors interact to promote carcinogenesis. Here we used Il10−/− mice colonized with bacteria previously associated with colorectal cancer: enterotoxigenic Bacteroides fragilis, Helicobacter hepaticus or colibactin-producing (polyketide synthase-positive (pks+)) Escherichia coli and fed either… Continue reading #Dietary fibre counters the oncogenic potential of colibactin-producing Escherichia coli in colorectal #cancer
#Aspirin prevents #metastasis by limiting platelet TXA2 suppression of T cell #immunity
Metastasis is the spread of cancer cells from primary tumours to distant organs and is the cause of 90% of cancer deaths globally1,2. Metastasizing cancer cells are uniquely vulnerable to immune attack, as they are initially deprived of the immunosuppressive microenvironment found within established tumours3. There is interest in therapeutically exploiting this immune vulnerability to… Continue reading #Aspirin prevents #metastasis by limiting platelet TXA2 suppression of T cell #immunity
Long-term #yogurt intake and colorectal #cancer incidence subclassified by Bifidobacterium abundance in tumor
Evidence suggests a tumor-suppressive effect of the intake of yogurt, which typically contains Bifidobacterium. We hypothesized that long-term yogurt intake might be associated with colorectal cancer incidence differentially by tumor subgroups according to the amount of tissue Bifidobacterium. We utilized the prospective cohort incident-tumor biobank method and resources of two prospective cohort studies. Inverse probability… Continue reading Long-term #yogurt intake and colorectal #cancer incidence subclassified by Bifidobacterium abundance in tumor
Defining ortholog-specific UHRF1 inhibition by STELLA for #cancer therapy
UHRF1 maintains DNA methylation by recruiting DNA methyltransferases to chromatin. In mouse, these dynamics are potently antagonized by a natural UHRF1 inhibitory protein STELLA, while the comparable effects of its human ortholog are insufficiently characterized, especially in cancer cells. Herein, we demonstrate that human STELLA (hSTELLA) is inadequate, while mouse STELLA (mSTELLA) is fully proficient… Continue reading Defining ortholog-specific UHRF1 inhibition by STELLA for #cancer therapy
PIN1 prolyl isomerase promotes initiation and progression of #bladder cancer through the SREBP2-mediated #cholesterol biosynthesis pathway
Identities of functional pSer/Thr.Pro protein substrates of the PIN1 prolyl isomerase and its effects on downstream signaling in bladder carcinogenesis remain largely unknown. Phenotypically, we found that PIN1 positively regulated bladder cancer cell proliferation, cell motility and urothelium clearance capacity in vitro and controlled tumor growth and potential metastasis in vivo. Mechanistically, we observed a… Continue reading PIN1 prolyl isomerase promotes initiation and progression of #bladder cancer through the SREBP2-mediated #cholesterol biosynthesis pathway
Association between recorded #physical activity and cancer progression or mortality in individuals diagnosed with #cancer in South Africa
Objectives This study aimed to determine the association between progression and mortality in individuals with stage 1 cancer and their recorded physical activity before the diagnosis of the cancer.Methods We included 28 248 members with stage 1 cancers enrolled in an oncology programme in South Africa. Physical activity was recorded using fitness devices, logged gym sessions… Continue reading Association between recorded #physical activity and cancer progression or mortality in individuals diagnosed with #cancer in South Africa
Transarterial #chemoembolisation combined with lenvatinib plus pembrolizumab versus dual placebo for unresectable, non-metastatic #hepatocellular carcinoma (LEAP-012): a multicentre, randomised, double-blind, phase 3 study
BackgroundTransarterial chemoembolisation (TACE) is standard care for unresectable, non-metastatic hepatocellular carcinoma. We aimed to evaluate the addition of lenvatinib and pembrolizumab to TACE versus dual placebo plus TACE in patients with unresectable, non-metastatic hepatocellular carcinoma.MethodsIn this multicentre, randomised, double-blind, phase 3 study (LEAP-012), patients were recruited from 137 global sites in 33 countries or regions.… Continue reading Transarterial #chemoembolisation combined with lenvatinib plus pembrolizumab versus dual placebo for unresectable, non-metastatic #hepatocellular carcinoma (LEAP-012): a multicentre, randomised, double-blind, phase 3 study
Stereotactic Body Radiotherapy vs #Sorafenib Alone in #Hepatocellular Carcinoma
Question Does stereotactic body radiation therapy (SBRT) prior to systemic therapy improve overall survival compared with systemic therapy alone in patients with locally advanced hepatocellular carcinoma (HCC)?Findings This phase 3 randomized clinical trial found that the use of SBRT prior to sorafenib was associated with clinically important but not statistically significant improved overall survival in… Continue reading Stereotactic Body Radiotherapy vs #Sorafenib Alone in #Hepatocellular Carcinoma
