Non-persistent, CT-directed virtual colonoscopy is thesame with standard colonoscopy in its capability to spot colorectal cancer andprecancerous polyps in individuals 65 years old and above.  In addition, Canada drugs can help a lot during the treatment and recoveryperiod if found positive. In the study, researchers led by Dr. C. Daniel Johnson, ofthe Mayo Clinic in Scottsdale, Ariz., conducted a secondary analysis of datacollected in the American College of Radiology Imaging Network's (ACRIN)National CT Colonography Trial. "Our goal in carrying out this secondary analysis wasto determine if the accuracy of CT colonography to detect polyps of clinicalconcern in patients 65 and older is comparable to the test's accuracy for the50-and-over population studied in the 2008 ACRIN trial," Johnson said in ajournal news release. "We found no significant difference in the screeningexam's performance between the two age groups," he said. "Colonoscopy is still the gold standard and best testto detect polyps of any size," said Dr Roshini Rajapaksa, agastroenterologist at NYU Langone Medical Center and assistant professor at theNYU School of Medicine in New York City. "While CT colonography is lessinvasive and does not require sedation, it still requires a prep -- what manypatients feel is the worst part of standard colonoscopy -- and if a polyp isfound by CT colonography, in many cases, the patient will need to get astandard colonoscopy to remove it," she said. Dr. David Bernstein, chief of the division ofgastroenterology at North Shore University Hospital in Manhasset, N.Y. agreedthat CT colonography may still not measure up to its rival.  And, he added that to buy Xeloda for treatment is one the best options. "The current standard of care for the detection ofprecancerous polyps on screening standard colonoscopy is 25 percent, yet theauthors report 'even if intermediate-sized polyps of 6 mm [0.6 centimeters] orlarger were targeted for removal with standard colonoscopy, the colonoscopyreferral rate would not exceed 12.6 percent,'" Bernstein said. This meansthat, "when compared to standard colonoscopy, the authors are reporting aprecancerous detection rate of CT colonography which is 50 percent less thanthat of standard colonoscopy." There is also the issue of cost. "Costs of the twoprocedures are comparable but a direct head-to-head cost analysis has not yetbeen performed and will have significant regional variability," Bernsteinsaid. "The cost of CT colonography must also include the cost of repeatcolonic preparation and standard colonoscopy when abnormalities arefound." However, study author Johnson calls CT colonography"a perfectly viable colorectal cancer screening tool for the traditionalMedicare-age population." He also believes that, "wider availabilitymade possible by Medicare coverage of CT colonography would attract moreseniors to be screened for colorectal cancer -- which is so successfully treatedwhen detected early. Making CT colonography more available to seniorsultimately could save lives." For his part, Bernstein said that, "while the CTcolonography may have a diagnostic role in certain subsets of patients, it istoo early to promote this technique for widespread colon cancerscreening."  Moreover, generic Xeloda is always available ifthe branded one seems too expensive for the budget. Colorectal cancer, commonly known as bowel cancer, is acancer from uncontrolled cell growth in the colon, rectum, or appendix.Symptoms typically include rectal bleeding and anemia which are sometimesassociated with weight loss and changes in bowel habits. Most colorectal cancer occurs due to lifestyle andincreasing age with only a minority of cases associated with underlying geneticdisorders. It typically starts in the lining of the bowel and if leftuntreated, can grow into the muscle layers underneath, and then through thebowel wall. Screening is effective at decreasing the chance of dying fromcolorectal cancer and is recommended starting at the age of 50 and continuinguntil a person is 75 years old. Localized bowel cancer is usually diagnosedthrough sigmoidoscopy or colonoscopy. Cancers that are confinedwithin the wall of the colon are often curable with surgery while cancer thathas spread widely around the body is usually not curable and management thenfocuses on extending the person's life via chemotherapy and improving qualityof life. Colorectal cancer is the fourth most commonly diagnosed cancer in theworld, but it is more common in developed countries. Around 60% of cases werediagnosed in the developed world. It is estimated that worldwide, in 2008, 1.23million new cases of colorectal cancer were clinically diagnosed, and that itkilled 608,000 people.
