A Canadian study found colonoscopy is associated with lower death rates from colorectal cancer, but raises concerns about detection of lesions on the right side of the colon. Patients are urged to seek a qualified gastrointestinal endoscopist to perform a thorough colonoscopy.
A new study by American College of Physicians reveals that colonoscopy strongly reduces mortality from left-sided colorectal cancer, while offering little benefit against right-sided cases. The researchers suggest factors such as incomplete examinations and varying tumor biology contribute to these limitations.
University of Texas Medical Branch researchers have identified a promising new target for colon cancer therapy by mapping the biochemical pathway critical to the spread of tumors. High levels of the enzyme Akt2 are found in association with other cancers, and its inhibition shows promise in stopping colon cancer's spread.
Researchers found that narrow-band imaging (NBI) was not more accurate than white light colonoscopy in differentiating colorectal polyps during real-time colonoscopy. However, NBI accuracy improved significantly after the endoscopists gained experience with the new diagnostic tool.
A major study of over 14,000 male physicians found that long-term vitamin E and C supplementation had no significant impact on prostate cancer or total cancer risk. The study suggests that these supplements may not be effective in preventing cancer in middle-aged and older men.
A long-term study found that high insulin-like growth factor binding protein-1 (IGFBP-1) levels reduced overall death risk by over 50%, while high C-peptide levels doubled the risk of death. Lifestyle factors like obesity and physical inactivity are associated with high insulin levels, which can fuel colon cancer growth.
Researchers found two insulin-related proteins that predict survival chances in colorectal cancer patients. High IGFBP-1 levels were associated with lower mortality rates, while high C-peptide levels increased the risk of overall death and other conditions.
Researchers found excellent agreement between CT colonography's bone density measurements and DEXA results, identifying osteoporotic bones in patients. CT colonography may be a cost-effective way to screen more people for osteoporosis without additional radiation.

The research highlights the importance of removing barriers to healthcare services, including screening tests and treatment for colorectal cancer.
A meta-analysis of 15 randomized controlled trials found that bevacizumab increases the risk of venous thromboembolism by 33% compared to controls. The risk is highest for patients with colorectal cancer, with an incidence rate of 19.1%.
A large clinical trial found that calcium supplementation reduced colorectal adenoma recurrence risk by 32% only in those with low magnesium to calcium ratio. This suggests a personalized diet/supplementation regimen considering both nutrients may be more effective than supplementing with one alone.
A recent study found that the cost of treating colorectal cancer can range from tens of thousands of dollars, with newer therapies often costing significantly more than older agents. This variation in costs raises questions about access to care and the value of these treatments for patients.
A study found that surgical removal of small colon polyps is not necessary due to low risk of cancer development. The study suggests that imaging surveillance for isolated small polyps detected during CT colonography may be an alternative to unnecessary colonoscopy procedures.

Alpha-catenin also showed distinct patterns in tumors of different colon locations, highlighting differences in molecular pathways between proximal and distal colon cancers.
A new colorectal screening procedure, CT colonography, has been found to be highly accurate in detecting intermediate and large polyps. The study, which used virtual reality technology, compared the accuracy of CT colonography with conventional colonoscopy and found that it was comparable in its ability to accurately detect problems.
A large study found that rescreening average-risk individuals after a normal initial colonoscopy every five years is sufficient to determine the optimal screening interval. The study's findings contradict previous recommendations of 10-year screenings and may impact screening costs and individual follow-up rates.
The AGA Institute concludes that CT colonography is a viable colorectal cancer screening option, detecting 90% of large polyps. However, small polyps are less detectable, and radiation risks are still uncertain. Colonoscopy remains the definitive test for early detection and prevention.
A new study found that people with an initial negative colonoscopy have a very low risk of developing colorectal cancer within five years. Based on this study, rescreening may not be necessary sooner than five years after the initial screening. The study's findings confirm what many gastroenterologists already believed.
Genetic testing identifies patients with advanced colorectal cancer who are likely to survive longer on cetuximab, a new standard of care for targeted therapies. Tumor cell analysis also reveals high levels of circulating cells before treatment as an indicator of disease aggressiveness.
Researchers at UC Davis have developed an interactive multimedia computer program to provide personalized education on colorectal cancer screening. The program aims to increase screening rates among Hispanic patients, who are less likely to receive screenings compared to non-Hispanic whites.
A new analysis reveals that fewer than half of older patients with colorectal cancer receive the recommended screening schedule to detect any recurrence. The study found that some patients may not meet guideline standards due to other procedures, while others receive testing that goes beyond guidelines.
A new study confirms that colorectal cancer screening should begin at age 50, with colonoscopies being the most effective method for preventing the disease. The study found that the prevalence of colorectal polyps increases sharply after age 50, and African Americans have a higher rate of right-sided polyps.
