There has been limited evidence for the association between chronic obstructive pulmonary disease (COPD) and the incidence of lung cancer among never smokers. We aimed to estimate the risk of lung cancer incidence in never smokers with COPD, and to compare it with the risk associated with smoking. This cohort study involved 338 548 subjects, 40… Continue reading Chronic #obstructive pulmonary disease and lung cancer incidence in never smokers: a cohort study

Plant‐based and animal‐based low‐carbohydrate #diets and risk of #hepatocellular carcinoma among US men and women
Little is known about the role of low‐carbohydrate diets (LCDs) in the development of hepatocellular carcinoma (HCC).. ..During 3,664,769 person years of follow‐up, there were 156 incident HCC cases. Although there were no associations between overall or animal‐based LCD score and risk of HCC, plant‐based LCD score was inversely associated with HCC risk (HR: 0.83;… Continue reading Plant‐based and animal‐based low‐carbohydrate #diets and risk of #hepatocellular carcinoma among US men and women
Intratumoral accumulation of gut #microbiota facilitates CD47-based immunotherapy via STING signaling
..Using one defined anaerobic gut microbiota to track whether microbiota interact with host immunity, we observed that Bifidobacterium facilitates local anti-CD47 immunotherapy on tumor tissues through the capacity to accumulate within the tumor microenvironment. Systemic administration of Bifidobacterium leads to its accumulation within the tumor and converts the nonresponder mice into responders to anti-CD47 immunotherapy… Continue reading Intratumoral accumulation of gut #microbiota facilitates CD47-based immunotherapy via STING signaling
CDC Colorectal Cancer Screening Test Use
Colorectal cancer (CRC) is the second leading cause of cancer death in the United States of cancers that affect both men and women. Despite strong evidence that screening for CRC reduces incidence and mortality, CRC screening prevalence is below the national target. This report describes current CRC screening prevalence by age, various demographic factors, and… Continue reading CDC Colorectal Cancer Screening Test Use
#Statin-induced GGPP depletion blocks macropinocytosis and starves cells with oncogenic defects
Our studies establish a connection between two isolated observations that 1) statins, taken by millions to lower cholesterol, have antitumor activity and 2) Ras-induced macropinocytosis is important in tumorigenesis. We discover that by depleting GGPP required for pseudopod extension and macropinocytosis, statins selectively kill cells with oncogenic defects by limiting nutrient uptake. https://bit.ly/2wT1ypw
#Colorectal Cancer Risk Following #Bariatric Surgery in a Nationwide Study of French Individuals With Obesity
..The mean (SD) follow-up was 6.2 (2.1) years for patients who underwent adjustable gastric banding, 5.5 (2.1) years for patients who underwent sleeve gastrectomy, and 5.7 (2.2) years for patients who underwent gastric bypass. In total, 13 052 incident colorectal cancers (1.2%) and 63 649 colorectal benign polyps were diagnosed. The rate of colorectal cancer was 0.6%… Continue reading #Colorectal Cancer Risk Following #Bariatric Surgery in a Nationwide Study of French Individuals With Obesity
Similar #Breast Cancer Risk in Women Older Than 65 Years Initiating Glargine, Detemir, and NPH Insulins
To assess whether initiation of insulin glargine (glargine), compared with initiation of neutral protamine Hagedorn (NPH) or insulin detemir (detemir), was associated with an increased risk of breast cancer in women with diabetes.. Ever use of glargine was not associated with an increased risk of breast cancer compared with NPH (HR 0.97; 95% CI 0.88–1.06)… Continue reading Similar #Breast Cancer Risk in Women Older Than 65 Years Initiating Glargine, Detemir, and NPH Insulins
Prevalence, Incidence, and Risk of Cancer in Patients With #Psoriasis and Psoriatic Arthritis A Systematic Review and Meta-analysis
..There was an increased risk of several cancers, including keratinocyte cancer (RR, 2.28; 95% CI, 1.73-3.01), lymphomas (RR, 1.56; 95% CI, 1.37-1.78), lung cancer (RR, 1.26; 95% CI, 1.13-1.40), and bladder cancer (RR, 1.12; 95% CI, 1.04-1.19). No increased risk of cancer for patients with psoriasis treated with biologic agents was found (RR, 0.97; 95%… Continue reading Prevalence, Incidence, and Risk of Cancer in Patients With #Psoriasis and Psoriatic Arthritis A Systematic Review and Meta-analysis
#Nut Consumption and Risk of #Cancer: A Meta-analysis of Prospective Studies
..When comparing the highest with the lowest category of nut intake, high consumption of nuts was significantly associated with decreased risk of overall cancer (RR = 0.90; 95% CI, 0.85–0.95). The protective effect of nut consumption was especially apparent against cancers from the digestive system (RR = 0.83; 95% CI, 0.77–0.89). Among different nut classes,… Continue reading #Nut Consumption and Risk of #Cancer: A Meta-analysis of Prospective Studies
