Ambulatory surgical centers provide safe alternatives to hospitals for screening colonoscopies, while the administration method may impact patient outcomes.
Chronic diseases are a major concern in Brazil, driven by increasing prevalence of risk factors such as obesity, hypertension, and diabetes.

A study found that colonoscopies were performed more frequently than recommended in some older Medicare beneficiaries, while others went without necessary follow-ups. The researchers suggest that closer attention to screening rates is needed to ensure the procedure is reserved for those who can benefit from it.
Activation of CTNNB1 biomarker is associated with better survival rates among obese patients with colorectal cancer, while physical activity improves survival for those without CTNNB1 activation. The study suggests a possible interactive effect between tumor CTNNB1 signaling and energy balance status on tumor cell behavior.

The ASGE has established guidelines for the use of real-time endoscopic assessment in managing diminutive colorectal polyps. The recommendations aim to minimize risk and delay while improving cost effectiveness of colonoscopy. Diminutive polyps are common, but pathological assessment can be costly and delay patient information.
A recent study found that hospital use of computed tomographic colonography (CTC), also known as virtual colonoscopy, is increasing. In 2008, 17% of hospitals offered CTC, up from 13% in 2005, with many citing a desire to provide alternative screening options for frail patients and those with failed optical colonoscopy.

A new study from the University of Michigan Comprehensive Cancer Center found that chemotherapy delays are common among patients with surgical complications after colorectal cancer surgery. The study, which analyzed data from 17,108 patients, suggests that surgical complications can have long-term impacts on quality of care.
A new study suggests that using fecal immunochemical testing between colonoscopies can detect colorectal cancer and advanced tumors in high-risk patients. The test detected 12 out of 14 cancers and 60 out of 96 advanced adenomas, reducing the chance of finding cancer or advanced adenoma by 50%.
A study published in The Lancet found that daily low-dose aspirin reduced death rates from a range of common cancers by 21% during trials. Long-term follow-up showed that the risk of cancer death remained 20-60% lower in groups who had previously been allocated aspirin.
Fecal immunochemical testing is the best and most cost-effective method for screening for colorectal cancer, reducing deaths by 69% among average-risk patients. Annual screening with this test can lower healthcare costs compared to other methods.
A new study found a 30-40% higher risk of colorectal cancer among men treated with hormone-based therapy for prostate cancer. The study suggests continued routine preventive care, including colorectal cancer screening, is essential during prostate cancer treatment.
A study found that women offered a female endoscopist were no more likely to undergo a screening colonoscopy than those without this option. Despite survey results suggesting high preference for female endoscopists, the study did not show an increase in screening rates.

A University of Illinois Chicago study found that black raspberries can prevent colorectal tumors in two mouse models, reducing tumor incidence by up to 60 percent. The findings suggest that black raspberries' ability to inhibit tumor development may be linked to their suppression of a protein called beta-catenin.
A recent study found that patients with MUTYH-associated polyposis have a statistically significant better survival rate than those with colorectal cancer from the general population. The five-year survival rate for MUTYH-associated polyposis was 78%, compared to 63% for control patients.
Researchers found a link between long telomeres and an increased risk of colorectal cancer in young-onset patients. The study suggests two distinct groups of colorectal cancer: one with accelerated aging due to telomere shortening, and another with longer telomeres.
A new investigational DNA methylation test has been shown to detect precancerous adenomas and cancers with high accuracy, detecting 64% of polyps over 1cm and 85% of cancers. The test is simple, non-invasive, and can be done from home, making it a promising alternative to traditional screening methods.
Researchers found a microRNA binding variant linked to improved survival rates in early-stage colorectal cancer patients, particularly those with KRAS mutations. The variant, previously associated with poor outcomes, was unexpectedly beneficial due to an unidentified compensatory pathway controlling the gene.
A study found that colorectal cancer patients with the KRAS p.G13D gene mutation had longer overall and progression-free survival when treated with cetuximab compared to those with other KRAS mutations. This suggests a potential benefit of cetuximab in certain patients with chemotherapy-refractory metastatic colorectal cancer.
A new study published in Cancer highlights the need to expand colorectal cancer screening to minority communities, particularly those without medical insurance. Offering screening at mammography visits is an effective way to generate interest and initiate the process, with 55% of participants going on to have a colonoscopy.
