Virtual Colonscopy Gets Nod
Colon cancer contributes to the huge burden of cancer-related mortality. In most cases, this malignancy is preventable if not responsive to treatment, particularly when diagnosed at an early stage of disease. With an eye on minimizing disease burden, researchers have been investigating the ideal screening modality.
A new study to be published in the June 1st issue of CANCER suggests that virtual colonoscopy, or CT colonography (CTC), may be the ideal method to screen for colon cancer. One particular benefit of this option is decreased morbidity compared to flexible sigmoidoscopy and optical colonoscopy. Both of these screening methods are associated with potential complications, such as abdominal pain to bowel perforation.
CTC has gained favor over the past few years as an alternative to screening. The technique requires the combination of X-rays and imaging software to produce multi-dimensional images of the colon. This modality is associated with a lower rate of complications and is more comfortable for patients. The test also has the required level of sensitivity to make it an appropriate and effective screening test.
