 FLAT POLYPS

ANCHOR LEAD: MORE THAN ONE TYPE OF POLYP IN THE COLON MAY LEAD TO CANCER, ELIZABETH TRACEY REPORTS

Polyps in the colon usually project from the colon wall and may lead to frank colon cancer, but now a flat type of polyp, previously thought to be largely found only in Asian peoples, is also seen to progress to cancer and is much more widespread than anyone knew.  Patrick Okolo, a gastroenterologist at Johns Hopkins, says this finding may obviate the advantages of CT for colon cancer screening.  

OKOLO:  The question is does it have the resolution to pick up these flat polyps, cause they’re flat, they’re small, they’re not so apparent, it requires some manipulation of light, some increased visual perception of these things and I think that that will have implications as to what’s the right way to get screened.  I think the best way to detect them is to go to somebody who can appreciate them and who has all the technology to improve our appreciation of them, including narrow band imaging and contrast and all sorts of optical tricks you can play with a colonoscope.            :30
