CT colonography may yet challenge colonoscopy
By Reuters Health
NEW YORK (Reuters Health), Apr 16 - Although CT colonography is a promising technique that has good sensitivity for detecting larger colon polyps and is less invasive than colonoscopy, it does not appear to be cost-effective for average-risk colorectal cancer screening. However, used in the right circumstances, the CT technique could prove to be economically viable, according to U.S. and Dutch researchers.

Adding chest CT to VC not cost-effective, study finds
By Eric Barnes
Adding a chest CT scan to screening virtual colonoscopy isn't cost-effective in a cohort of average-risk patients, a new model-based analysis concluded. Although the additional anatomic coverage increased the clinical efficiency of CT-based screening, the combined test would not detect enough serious pathology to cover the costs of detection and follow-up of disease.

Fecal occult blood screening may help reduce colorectal cancer mortality
By Reuters Health
NEW YORK (Reuters Health), Apr 6 - Pilot studies indicate that a population-based approach to guaiac fecal occult blood testing (FOBT) appears likely to reduce colorectal cancer mortality, Scottish researchers report in the April issue of Gut.

Virtual colonoscopy CAD finds most cancers
By Eric Barnes
A computer-aided detection (CAD) algorithm designed to find polypoid lesions of the colon also does fairly well at finding frank cancers, researchers from the U.K. concluded. But sensitivity varies depending on the system settings and the quality of the prep.

Digital tomo works well for some kidney, ureteral stones
By Brian Casey
A new study by Belgian researchers indicates that digital tomosynthesis could be useful for assessing ureteral and kidney stones, particularly for screening patients prior to CT. But the digital radiography technique has different levels of accuracy depending on the location and size of stones.

Automated CT volumetry of lymph nodes gauges treatment response
By Eric Barnes
Cancer patients who respond to neoadjuvant therapy have a better prognosis than nonresponders, of course, but with the exception of FDG-PET, reductions in the size of tumors treated with chemotherapy or radiation have been difficult to gauge using imaging modalities that are capable of delineating the anatomy.

VC/AAA screening combo cost-effective in older adults
By Eric Barnes
A new analytic model has found that virtual colonoscopy is a highly cost-effective colon cancer screening method for older adults in the Medicare population, especially when combined with screening for abdominal aortic aneurysm (AAA), a test performed using the same CT dataset at little additional cost.

Cancer cure rates on the rise in Europe: study
By Reuters Health
LONDON (Reuters), Mar 24 - More Europeans are beating cancer, perhaps due to more widespread screening and earlier diagnosis, according to a study published on Tuesday.

Colonoscopy seen as reducing CRC mortality in Germany
By AuntMinnieEurope.com staff writers
A colonoscopy screening program is expected to have a powerful impact on colorectal cancer (CRC) deaths in Germany, despite a low rate of participation among eligible participants, according to the first published results of an eight-year study of nearly 2 million screened individuals.

Study: Endovascular repair can come first for AAA
By AuntMinnieEurope.com staff writers
Researchers of a new U.K. study recommend endovascular or endograft repair as a first-line treatment for abdominal aortic aneurysm (AAA), given that the low reintervention rates are comparable to those reported for open surgical repair.

Minimal prep VC nearly as sensitive, better tolerated
By Eric Barnes
VIENNA - A new study from the U.S. and Japan found that full-laxative and minimum-laxative virtual colonoscopy had equivalent sensitivities for detecting colorectal polyps 6 mm and larger, though specificity fell in the minimum-prep regimen. The patients were happy to skip the laxatives, however.
