Recombinant approach helps T cells target colorectal tumors

By Reuters Health

NEW YORK (Reuters Health), Aug 8 - T cells from colorectal cancer patients can be transduced with a recombinant anticarcinoembryonic antigen (CEA) immunoreceptor so that they become activated by their autologous tumor cells, German researchers report in the August issue of Gut.

Familial risks of colon and rectal cancer differ

By Reuters Health

NEW YORK (Reuters Health), Jul 28 - Family history contributes differently to the risks of colon cancer and rectal cancer, suggesting these malignancies may have different causative factors, according to an analysis of data from the Icelandic Cancer Registry and a genealogy database.

A single negative colonoscopy may suffice for average-risk patients

By Reuters Health

NEW YORK (Reuters Health), Jul 25 - Most expert panels have recommended that colonoscopy be repeated every 10 years after an initial negative result. However, researchers in Germany now report that the risk of colorectal cancer following an initial negative screening colonoscopy is quite low and it need not be repeated for at least 20 years "if at all."

Model may help identify hereditary colorectal cancer

By Reuters Health

NEW YORK (Reuters Health), Jun 29 - Researchers in the U.K. have developed a method to identify patients with colorectal cancer that have mutations in DNA mismatch-repair genes. However, carriage of such mutations did not affect survival, according to a report in the New England Journal of Medicine for June 29.

Swedes want to perform VC, but many lack equipment, training

By Eric Barnes

Less than a quarter of Sweden's radiology departments perform virtual colonoscopy, but not for lack of interest in the procedure, a new study finds. Rather, the lack of multidetector CT scanners and training opportunities were the top reasons for not performing VC.

No long-term rise in colon cancer for ulcerative colitis patients

By Reuters Health

NEW YORK (Reuters Health), May 1 - The incidence of colorectal cancer (CRC) remains constant in ulcerative colitis (UC) patients up to 40 years of disease duration, a new study from the U.K. shows.

Colon CAD: VC's extra eyes face new challenges

By Eric Barnes

Prototype colon CAD systems are proliferating, and thanks to years of painstaking development work they're doing a pretty good job, outperforming all but the best radiologists in the detection of colonic lesions. VC CAD expert Dr. Hiro Yoshida from Harvard Medical School in Boston discusses the major innovations that have produced today's complex CAD systems, and the moving target CAD developers face in keeping up with new performance standards.

Model saves time, radiation by simulating anatomic changes during radiotherapy

By Eric Barnes

Organs and tumors can twist, turn, and deform substantially during radiotherapy, creating a moving target for treatment planners seeking to avoid irradiating normal tissue. One solution, a full CT scan before each treatment, is both time- and radiation-intensive. But what if doctors could simply "update" the pretreatment scan with a few newly acquired planar projection images? Researchers from Virginia built and tested a model to do just that.

Interventionalists see safer RFA with coregistered laparoscopic US, CT

By Eric Barnes

BERLIN - Percutaneous radiofrequency ablation (RFA) and other minimally invasive interventions have become increasingly popular. But the interventionalists who perform them often end up working in the dark, as the CT or MR image they've placed across the room bears little resemblance to the laparoscopic ultrasound images used to guide the RFA needle. Researchers may have found a solution, according to a presentation at the Computer Assisted Radiology and Surgery (CARS) meeting.
