VC is cost-effective for screening; tiny polyps can be ignored
By Eric Barnes
Virtual colonoscopy is a cost-effective way to screen for colorectal cancer -- provided that individuals with tiny lesions aren't referred for polypectomy, according to the results of a new study from France.

Virtual colonoscopy preferred for surveillance follow-up
By Eric Barnes
Patients referred for polyp surveillance after virtual colonoscopy are more likely to opt for another VC exam at follow-up, Italian researchers report. But patients want their follow-up scans sooner rather than later.

Screening men for abdominal aortic aneurysm saves lives, but is it cost-effective?
By Reuters Health
NEW YORK (Reuters Health), Jun 26 - The results of a U.K. study suggest that screening older men for abdominal aortic aneurysm (AAA) provides a durable survival benefit and becomes cost-effective over time. However, in a Danish study, screening for AAA in older men did not seem to be cost-effective.

Readers undaunted by VC CAD false positives
By Eric Barnes
Radiologists examining data from virtual colonoscopy studies can easily dismiss increasing numbers of false-positive detections generated by computer-aided detection (CAD) systems, researchers from the U.K. report. But the presence of more false positives makes reading less efficient.

Virtual colonoscopy CAD improves flat-lesion detection
By Eric Barnes
Computer-aided detection (CAD) software can improve the detection of flat lesions at virtual colonoscopy -- as long as the lesions are at least 1 mm high. In a new study from Italy, CAD detected 94% of all flat lesions; however, radiologists dismissed a few of them incorrectly as false positives.

Season may not alter cancer survival in short term
By Reuters Health
NEW YORK (Reuters Health), May 20 - Some studies have found that patients with certain cancers seem to survive longer when they're diagnosed during summer and autumn months, but it now appears that this may be largely due to higher death rates in general during winter months, report U.K. researchers from King's College London.

VC not cost-effective in FOBT-positive screening population
By Eric Barnes
Patients with positive screening results on fecal occult blood tests (FOBTs) should probably head straight to optical colonoscopy for their next exam, according to a new study from the Netherlands. Virtual colonoscopy may not be cost-effective in this population because so many FOBT-positive patients would need referral for polypectomy anyway, the researchers said.
