Association Between Time to Colonoscopy after Positive Fecal Testing and Colorectal Cancer Outcomes: a Systematic Review

Colonoscopy is required following a positive fecal screening test for colorectal cancer (CRC). It remains unclear to what extent time to colonoscopy is associated with CRC-related outcomes. We performed a systematic review to elucidate this relationship.. ..From 1,612 initial studies, 8 were included in the systematic review, with 5 reporting outcomes for FIT. Although meta-analysis was not possible, consistent trends between longer time delays and … Continue reading Association Between Time to Colonoscopy after Positive Fecal Testing and Colorectal Cancer Outcomes: a Systematic Review

#HPV Vaccination and the Risk of Invasive #Cervical Cancer

The efficacy and effectiveness of the quadrivalent human papillomavirus (HPV) vaccine in preventing high-grade cervical lesions have been shown. However, data to inform the relationship between quadrivalent HPV vaccination and the subsequent risk of invasive cervical cancer are lacking.. ..During the study period, we evaluated girls and women for cervical cancer until their 31st birthday. Cervical cancer was diagnosed in 19 women who had received … Continue reading #HPV Vaccination and the Risk of Invasive #Cervical Cancer

#ASPIRIN AND THE RISK OF NON‐DIGESTIVE TRACT CANCERS: AN UPDATED META‐ANALYSIS TO 2019

Aspirin has been associated to a reduced risk of colorectal and other selected digestive tract cancers, but the evidence other neoplasms is still controversial. In order to provide an up‐to‐date quantification of the role of aspirin on lung, breast, endometrium, ovary, prostate, bladder, and kidney cancer, we conducted a systematic review and meta‐analysis of all observational studies published up to March 2019. We estimated pooled … Continue reading #ASPIRIN AND THE RISK OF NON‐DIGESTIVE TRACT CANCERS: AN UPDATED META‐ANALYSIS TO 2019

Association of #Coffee Intake With Survival in Patients With Advanced or Metastatic #Colorectal Cancer

Several compounds found in coffee possess antioxidant, anti-inflammatory, and insulin-sensitizing effects, which may contribute to anticancer activity. Epidemiological studies have identified associations between increased coffee consumption and decreased recurrence and mortality of colorectal cancer. The association between coffee consumption and survival in patients with advanced or metastatic colorectal cancer is unknown.. ..Among the 1171 patients included in the analysis (694 men [59%]; median age, 59 … Continue reading Association of #Coffee Intake With Survival in Patients With Advanced or Metastatic #Colorectal Cancer

#Aspirin use and risk of #breast cancer in African American women

Use of aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) has been hypothesized to be associated with reduced risk of breast cancer; however, results of epidemiological studies have been mixed. Few studies have investigated these associations among African American women.. To assess the relation of aspirin use to risk of breast cancer in African American women, we conducted a prospective analysis within the Black Women’s Health … Continue reading #Aspirin use and risk of #breast cancer in African American women

#Obesity Has a Stronger Relationship with Colorectal #Cancer in Postmenopausal Women Than Premenopausal Women

Background: To examine the relationship between obesity measured by waist circumference (WC) and body mass index (BMI) and the incidence of colorectal cancer (CRC) in premenopausal and postmenopausal women. Methods: A total of 1,418,180 premenopausal and 4,854,187 postmenopausal women without cancer at baseline and aged over 40 were identified using the Korean National Health Insurance System Cohort during 2009-2014. The hazard ratio (HR) for CRC … Continue reading #Obesity Has a Stronger Relationship with Colorectal #Cancer in Postmenopausal Women Than Premenopausal Women

Personal use of permanent hair #dyes and #cancer risk and mortality in US women: prospective cohort study

Ever users of permanent hair dyes had no significant increases in risk of solid cancers (n=20 805, excluding non-melanoma skin cancers; hazard ratio 0.98, 95% confidence interval 0.96 to 1.01) or hematopoietic cancers overall (n=1807; 1.00, 0.91 to 1.10) compared with non-users. Additionally, ever users did not have an increased risk of most specific cancers (cutaneous squamous cell carcinoma, bladder cancer, melanoma, estrogen receptor positive breast … Continue reading Personal use of permanent hair #dyes and #cancer risk and mortality in US women: prospective cohort study

Association of #Menopausal Hormone Therapy With Breast #Cancer Incidence and Mortality During Long-term Follow-up of the Women’s Health Initiative Randomized Clinical Trials

In the trial involving 16 608 women with a uterus, 8506 were randomized to receive 0.625 mg/d of conjugated equine estrogen (CEE) plus 2.5 mg/d of medroxyprogesterone acetate (MPA) and 8102, placebo. In the trial involving 10 739 women with prior hysterectomy, 5310 were randomized to receive 0.625 mg/d of CEE alone and 5429, placebo. The CEE-plus-MPA trial was stopped in 2002 after 5.6 years’ median intervention … Continue reading Association of #Menopausal Hormone Therapy With Breast #Cancer Incidence and Mortality During Long-term Follow-up of the Women’s Health Initiative Randomized Clinical Trials

Dietary Lipids Induce Ferroptosis in Caenorhabditis elegans and Human Cancer Cells

Dietary lipids impact development, homeostasis, and disease, but links between specific dietary fats and cell fates are poorly understood. Ferroptosis is an iron-dependent form of nonapoptotic cell death associated with oxidized polyunsaturated phospholipids. Here, we show that dietary ingestion of the polyunsaturated fatty acid (PUFA) dihomogamma-linolenic acid (DGLA; 20:3n-6) can trigger germ-cell ferroptosis and sterility in the nematode Caenorhabditis elegans. Exogenous DGLA is also sufficient … Continue reading Dietary Lipids Induce Ferroptosis in Caenorhabditis elegans and Human Cancer Cells

Does adequate physical activity attenuate the associations of alcohol and alcohol‐related cancer mortality? A pooled study of 54 686 British adults

The potential of physical activity (PA) to attenuate the effects of alcohol consumption on the risks of alcohol‐related cancer mortality is unknown. We used data from participants aged 30 years and over in 10 British population‐based surveys (Health Surveys for England 1994, 1997, 1998, 1999, 2003, 2004, 2006 and 2008 and the Scottish Health Surveys 1998 and 2003). Alcohol‐related cancer mortality included oral cavity, throat, larynx, … Continue reading Does adequate physical activity attenuate the associations of alcohol and alcohol‐related cancer mortality?

#ACE (Angiotensin-Converting Enzyme) Inhibitors/Angiotensin Receptor Blockers Are Associated With Lower #Colorectal Cancer Risk

Whether ACE (angiotensin-converting enzyme) inhibitors and angiotensin receptor blockers modify colorectal cancer risk remains controversial. We aimed to determine association between their use and colorectal cancer risk after a negative baseline colonoscopy. This is a territory-wide retrospective cohort study recruiting patients aged ≥40 who had undergone colonoscopy between 2005 and 2013. Exclusion criteria included colorectal cancer detected <6 months of index colonoscopy, prior colorectal cancer, … Continue reading #ACE (Angiotensin-Converting Enzyme) Inhibitors/Angiotensin Receptor Blockers Are Associated With Lower #Colorectal Cancer Risk

Impact of the faecal immunochemical test on colorectal cancer survival

There is already evidence that the faecal immunochemical test (FIT) is a useful tool for the diagnosis of colorectal cancer (CRC) that helps to identify symptomatic patients requiring early colonoscopy. Although the recommendation to use FIT is widely accepted, there are no data concerning whether this strategy improves patient survival.The objective was to assess whether the survival is higher if CRC patients have been first … Continue reading Impact of the faecal immunochemical test on colorectal cancer survival
