A large study found that colonoscopy screening can prevent up to 40% of colorectal cancers, with more frequent intervals recommended for those with a personal history of adenoma or family history of colorectal cancer. The study also suggests that sigmoidoscopy alone is insufficient for reducing the incidence of proximal colon cancer.
A new method uses a combination of techniques to detect genetic variations that initiate colon cancer. The technique achieved high sensitivity and was able to detect APC variations in 41 out of 80 samples, including previously unknown variations.

A new laxative-free CT colonography technique has been shown to be effective in detecting high-risk polyps, with an accuracy comparable to traditional colonoscopy. The procedure uses computer-aided systems to virtually cleanse and analyze images, reducing discomfort and preparation requirements.
Researchers found that a comprehensive care management program for chronic obstructive pulmonary disease (COPD) may not be safe or suitable for patients, as it led to excess mortality. In contrast, laxative-free colonography proved accurate in detecting most significant lesions and eliminated a major barrier to colon cancer screening. ...
A study of 7,424 privately insured colon cancer patients found that managed care presence and hospital competition increased the likelihood of laparoscopic surgery, which lowered costs. The researchers also discovered a 10% increase in HMO penetration was associated with a 10.3% increase in laparoscopy utilization.

A study by Fred Hutchinson Cancer Center found that women with low levels of fetal cells have a 70% lower risk of breast cancer, while those with high levels have a four-fold increased risk for colon cancer. The biological reasons behind this contradictory effect are unknown and require further investigation.
Dr. Scott Waldman has received a CURE grant to develop a molecular diagnostic test that identifies patients who will benefit from adjuvant chemotherapy, reducing racial disparities in colon cancer mortality. The test uses guanylyl cyclase C as a biomarker and could help stratify patients into more targeted treatment groups.

The study revealed a dose-response relationship between the number of morbidities and the prevalence of colon cancer screening.
A study found that hospitals in Ontario with higher spending on intensive care and specialists had lower death rates, hospital readmissions, and better quality of care for severely ill patients. Higher-spending hospitals also saw longer lengths of stay and more medical specialist visits.
A survey of over 1,000 gastroenterologists found that pressure to increase colonoscopy volume negatively affects procedure quality and safety. Gastroenterologists reported reducing time examining the colon wall or aborting difficult procedures due to production pressures.
Scientists have developed a new aspirin compound called NOSH-aspirin that curbs the growth of 11 different types of human cancer cells in culture and shrinks human colon cancer tumors by 85% in live animals without adverse effects. The hybrid is more potent and safer than classic aspirin, requiring lower doses to be effective.
Researchers at Temple University found that high-fat diets alter metabolic pathways in healthy colon tissue, leading to increased colon cancer risk. Epigenetic marks on genes involved in breaking down carbohydrates and lipids were retrained in normal tissue from patients with colon cancer.
