Importance The effect of testosterone replacement therapy (TRT) on the risk of prostate cancer and other adverse prostate events is unknown.Objective To compare the effect of TRT vs placebo on the incidences of high-grade prostate cancers (Gleason score ≥4 + 3), any prostate cancer, acute urinary retention, invasive prostate procedures, and pharmacologic treatment for lower urinary tract… Continue reading #Prostate Safety Events During #Testosterone Replacement Therapy in Men With HypogonadismA Randomized Clinical Trial

Enhanced SREBP2-driven #cholesterol biosynthesis by PKCλ/ι deficiency in intestinal epithelial cells promotes aggressive serrated tumorigenesis
The metabolic and signaling pathways regulating aggressive mesenchymal colorectal cancer (CRC) initiation and progression through the serrated route are largely unknown. Although relatively well characterized as BRAF mutant cancers, their poor response to current targeted therapy, difficult preneoplastic detection, and challenging endoscopic resection make the identification of their metabolic requirements a priority. Here, we demonstrate… Continue reading Enhanced SREBP2-driven #cholesterol biosynthesis by PKCλ/ι deficiency in intestinal epithelial cells promotes aggressive serrated tumorigenesis
The #sex gap in #bladder cancer survival — a missing link in bladder #cancer care?
The differences in bladder cancer outcomes between the sexes has again been highlighted. Uncommon among cancers, bladder cancer outcomes are notably worse for women than for men. Furthermore, bladder cancer is three to four times more common among men than among women. Factors that might explain these sex differences include understanding the importance of haematuria… Continue reading The #sex gap in #bladder cancer survival — a missing link in bladder #cancer care?
Detection of high-risk #polyps at screening colonoscopy indicates risk for #liver and #biliary #cancer death
Hepatobiliary cancers share risk factors with colorectal cancer (CRC), but there are no combined screening programs for these conditions.AimsThe aim of this study was to assess whether patients with high-risk colonic polyps are more likely to die from liver related tumors than patients with a negative colonoscopy.MethodsIn this retrospective analysis of mortality data, Austrian screening… Continue reading Detection of high-risk #polyps at screening colonoscopy indicates risk for #liver and #biliary #cancer death
#Nicotinamide enhances natural #killer cell function and yields remissions in patients with non-Hodgkin #lymphoma
Administration of haploidentical donor natural killer (NK) cells, rituximab, and IL-2 to patients with non-Hodgkin lymphoma (NHL) has been shown to be safe, but the objective response rate was low, suggesting that further strategies to improve NK cell engraftment and function are needed. Here, Cichocki and colleagues showed that supplementation with nicotinamide during ex vivo… Continue reading #Nicotinamide enhances natural #killer cell function and yields remissions in patients with non-Hodgkin #lymphoma
Long-term #cancer outcomes after #bariatric surgery
ObjectiveObesity is associated with increased cancer risk. Because of the substantial and sustained weight loss following bariatric surgery, postsurgical patients are ideal to study the association of weight loss and cancer.MethodsRetrospectively (1982–2019), 21,837 bariatric surgery patients (surgery, 1982–2018) were matched 1:1 by age, sex, and BMI with a nonsurgical comparison group. Procedures included gastric bypass,… Continue reading Long-term #cancer outcomes after #bariatric surgery
#Depression, #anxiety, and the risk of #cancer: An individual participant data meta-analysis
Depression and anxiety have long been hypothesized to be related to an increased cancer risk. Despite the great amount of research that has been conducted, findings are inconclusive. To provide a stronger basis for addressing the associations between depression, anxiety, and the incidence of various cancer types (overall, breast, lung, prostate, colorectal, alcohol-related, and smoking-related… Continue reading #Depression, #anxiety, and the risk of #cancer: An individual participant data meta-analysis
Screening for Colorectal Cancer in Asymptomatic Average-Risk Adults: A Guidance Statement From the American College of Physicians (Version 2)
The purpose of this updated guidance statement is to guide clinicians on screening for colorectal cancer (CRC) in asymptomatic average-risk adults. The intended audience is all clinicians. The population is asymptomatic adults at average risk for CRC.Methods:This updated guidance statement was developed using recently published and critically appraised clinical guidelines from national guideline developers since… Continue reading Screening for Colorectal Cancer in Asymptomatic Average-Risk Adults: A Guidance Statement From the American College of Physicians (Version 2)
Interferon signaling promotes tolerance to chromosomal instability during metastatic evolution in renal cancer
Molecular routes to metastatic dissemination are critical determinants of aggressive cancers. Through in vivo CRISPR–Cas9 genome editing, we generated somatic mosaic genetically engineered models that faithfully recapitulate metastatic renal tumors. Disruption of 9p21 locus is an evolutionary driver to systemic disease through the rapid acquisition of complex karyotypes in cancer cells. Cross-species analysis revealed that… Continue reading Interferon signaling promotes tolerance to chromosomal instability during metastatic evolution in renal cancer
