Biomarker identification may lead to new noninvasive test for colorectal cancer detection
The average five-year survival for colorectal cancer is less than 10 percent if metastasis occurs, but can reach 90 percent if detected early. A new non-invasive test has been developed that measures methylation of the SDC2 gene in tissues and blood sera. This test detected 87 percent of all stages of colorectal cancer cases (sensitivity) without significant difference between early and advanced stages, while correctly identifying 95 percent of disease-free patients (specificity).

New blood tests promise simple, cost-effective diagnosis of gastrointestinal cancers
Promising results from two new blood tests that can aid in the early identification of patients with gastrointestinal cancers will be presented at Europe's largest cancer congress, ECCO 15 -- ESMO 34, in Berlin on Monday September 21. The tests will make GI cancer detection simpler, cost-effective, and more acceptable to patients than current methods, the researchers say. (2009-09-20)

Study provides evidence supporting recommended 10 year interval for colonoscopies for most patients

Calcium supplements can lower risk of advanced colon polyps
While taking calcium supplements can decrease the risk of all types of colorectal polyps, research led by Dartmouth Medical School shows calcium had the greatest effect on advanced colorectal adenomas, considered to be most strongly associated with invasive colorectal cancer. The study, reported in the June 16 issue of the Journal of the National Cancer Institute, provides more evidence that calcium supplementation appears to be a safe and inexpensive way to reduce colorectal polyps.

More than 41 million Americans need colorectal cancer screening
More than 41 million Americans who are candidates for colorectal cancer screening have not been screened for this second-leading cancer killer, the first time the unscreened population has been quantified. According to a study published today in the American Gastroenterological Association (AGA) journal Gastroenterology, sufficient capacity exists to screen the unscreened population within one year using fecal occult blood testing (FOBT) followed by diagnostic colonoscopy for positive tests.

Lower-income families with high-deductible health plans may put off care because of costs
Lower-income families in high-deductible health plans appear more likely to delay or forgo medical care based on cost than higher-income families with similar coverage, according to a report in the Nov. 22 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. However, lower-income families did not report any more troubles understanding or using their plans. (2010-11-22)

The Visible Humans: Coming Of Age
Since the Visible Human Male and Female were created (in 1994 and 1995 respectively), more than 1,000 agreements have been signed with scientists around the world, to use these amazing computer images of the human body. An October 1st press conference presents some of the most fascinating applications of the Visible Humans, giving us a window on what medicine will be like in the next millennium. Press event: 11:30 a.m., Thurs., Oct. 1. (1998-09-22)

Researchers release baseline data from randomized colorectal cancer screening trial
A major trial is under way to determine the impact of single screening sigmoidoscopy on colorectal cancer incidence and mortality. Although the trial will take years to complete, outcomes from the recruitment and screening phases of the trial suggest that single screening sigmoidoscopy has a high cancer detection rate and is relatively safe and acceptable to patients. The findings appear in the December 4 issue of the Journal of the National Cancer Institute. (2002-12-03)

Fecal occult blood testing effective in colonoscopy screenings
Fecal immunochemical testing (FIT) is more effective in its health benefits at the same or lower costs compared to guaiac fecal occult blood testing (gFOBT) at all levels of colonoscopy capacity, according to a study published Nov. 9 by the Journal of the National Cancer Institute. (2011-11-09)

Nurse navigators may aid colon cancer screening follow-up
Group Health patients with a positive screening test for colon cancer (a stool test or sigmoidoscopy) tended to be more likely to get the recommended follow-up test, a diagnostic colonoscopy, if nurse navigators contacted them than if they got usual care, according to Beverly B. Green, MD, MPH, a Group Health physician and a Group Health Research Institute associate investigator. (2014-11-07)

Racial disparities still exist in colorectal cancer screening despite increased Medicare coverage
Despite expanded Medicare coverage for colorectal cancer screening tests, lower rates still exist among blacks and Hispanics compared to other ethnic groups, according to research published in Cancer, Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research. (2011-05-05)

Surveillance colonoscopy should be targeted to high-risk patients
Surveillance colonoscopy is effective and cost-effective when targeted to high-risk patients. (2010-06-21)

Actor-robots 'staff' part of new $5M simulation training center
A new $5 million medical and surgical simulation training center located at the Johns Hopkins Outpatient Center in East Baltimore opened in March. The (2008-03-27)

Dropping it in the mail: Best practices detailed for mail-in colon cancer screenings
A program that asks patients to mail in stool samples to screen for colon cancer is an effective way to expand screenings to underserved and underinsured communities and offers an alternative to in-person testing during the pandemic, according to a study conducted by UT Southwestern. (2020-09-08)

Attack on C. difficile: How can we combat this serious health issue
In five different studies, researchers explored the impact of various factors on increasing rates of Clostridium difficile infection (C. difficile), such the substantial increase in antibiotic use due to new National Hospital Quality Measures; strategies to combat high rates of C. difficile infections; and cutting‐edge treatments for this potentially deadly -- and quite common -- infection. (2010-10-18)

New study argues for CT colonography as primary colon cancer screening test
CT colonography allows radiologists to predict, with a high degree of confidence, whether or not a polyp needs to be evaluated through colonoscopy or removed through polypectomy, according to a study performed at the University of Wisconsin School of Medicine and Public Health in Madison, Wis. (2009-04-23)

Less invasive CT-scan based colorectal cancer screening method shows good accuracy

UCLA/VA study: Many patients not receiving follow-up tests after positive screening for colon cancer
A UCLA/Veteran's Affairs study showed that more than 40 percent of patients who initially had received a positive result on a fecal occult blood test (FOBT) -- an initial screening tool for colon cancer -- did not receive appropriate diagnostic follow-up tests such as a colonoscopy or barium enema in 2002. (2006-05-30)

Use of frozen material for fecal transplant successfully treats C. difficile infection
A pilot study by Massachusetts General Hospital investigators may lead to greater availability and acceptability of an unusual treatment for a serious medical problem -- use of fecal material from healthy donors to treat recurrent diarrhea caused by the Clostridium difficile bacteria. The researchers report that use of prescreened frozen material from donors unrelated to patients was as successful in curing recurrent C. difficile as was the use of fresh fecal material reported in previous studies.

Enhanced imaging techniques could improve medical diagnosis
Chris Wyatt is a Virginia Tech electrical engineer who is attempting to provide the medical community with better, quicker, and more relevant images of the human body. The side effects are not bad either -- lower medical costs, new treatments, and earlier disease detection. Wyatt is specifically looking at improving imaging for virtual colonoscopies; developing algorithms to replace extensive manual work in brain imaging; and developing image-guided polypectomy technology.
