Hispanic Men Are More Likely To Suffer From Polyps in Colon Than Women

Hispanic Men Are More Likely To Suffer From Polyps in Colon Than Women.
Among Hispanics, men are twice as right as women to have colon polyps and are also more appropriate to have multiple polyps, a restored study in Puerto Rico has found. The researchers also found that the scan patients older than 60 were 56 percent more likely to have polyps than those younger than 60. Polyps are growths in the stocky intestine. Some polyps may already be cancerous or can become cancerous.

The exploration included 647 patients aged 50 and older undergoing colorectal cancer screening at a gastroenterology clinic in Puerto Rico. In 70 percent of patients with polyps, the growths were on the dexter sect of the colon. In white patients, polyps are typically found on the left incidental of the colon. This difference may result from underlying molecular differences in the two patient groups, said examination author Dr Marcia Cruz-Correa, an associate professor of medicine and biochemistry at the University of Puerto Rico Cancer Center.

The decree about polyp location is important because it highlights the call to use colonoscopy when conducting colorectal cancer screening in Hispanics. This is the most effective pattern of detecting polyps on the right side of the colon. The study was to be presented Sunday at the Digestive Diseases Week meet in New Orleans.

Smokers Get Sick Of Colorectal Cancer Earlier

Smokers Get Sick Of Colorectal Cancer Earlier.
A callow swat has uncovered a strong link between smoking and the development of precancerous polyps called non-reflective adenomas in the large intestine, a finding that researchers say may explain the earlier onset of colorectal cancer in the midst smokers. Flat adenomas are more aggressive and harder to spot than the raised polyps that are typically detectable during column colorectal screenings, the authors noted. This fact, coupled with their affiliation with smoking, could also explain why colorectal cancer is usually caught at a more advanced stage and at a younger maturity among smokers than nonsmokers.

So "Little is known regarding the risk factors for these boring lesions, which may account for over one-half of all adenomas detected with a high-definition colonoscope," study author Dr Joseph C Anderson, of the Neag Comprehensive Cancer Center at the University of Connecticut Health Center, said in a talk manumitting from the American Society for Gastrointestinal Endoscopy. But, "smoking has been shown to be an distinguished risk factor for colorectal neoplasia tumor formation in several screening studies".

A New Factor Of Increasing The Risk Of Colon Cancer Was Studied

A New Factor Of Increasing The Risk Of Colon Cancer Was Studied.
Researchers article that expensive levels of a protein measured through blood tests could be a cypher that patients are at higher risk of colon cancer. And another new reflect on finds that in blacks, a common germ boosts the risk of colorectal polyps - offbeat tissue growths in the colon that often become cancerous.

Both studies are slated to be presented Monday at the American Association for Cancer Research (AACR) annual encounter in Washington, DC. One study links important levels of circulating C-reactive protein to a higher risk of colon cancer. Protein levels take to the air when there's low-grade inflammation in the body.

So "Elevated CRP levels may be considered as a jeopardy marker, but not necessarily a cause, for the carcinogenic process of colon cancer," Dr Gong Yang, enquiry associate professor at Vanderbilt University, said in an AACR news release. Yang and colleagues intentional 338 cases of colorectal cancer among participants in the Shanghai Women's Health Study and compared them to 451 women without the disease.

Women whose protein levels were in the highest post had a 2,5 - shut down higher risk of colon cancer compared to those in the lowest quarter. In the other study, researchers linked the bacterium Helicobacter pylori to a higher gamble of colorectal polyps in blacks. That could press it more likely that they'll develop colon cancer.

But "Not each and every one gets sick from H pylori infection, and there is a legitimate concern about overusing antibiotics to touch on it," said Dr Duane T Smoot, chief of the gastrointestinal allotment at Howard University, in a statement. However, the majority of the time these polyps will become cancerous if not removed, so we basic to screen for the bacteria and treat it as a possible cancer prevention strategy. The learning authors, who examined the medical records of 1262 black patients, found that the polyps were 50 percent more omnipresent in those who were infected with H pylori.

New Non Invasive Test For Detection Of Tumors Of The Colon Is More Accurate Than Previously Used

New Non Invasive Test For Detection Of Tumors Of The Colon Is More Accurate Than Previously Used.
A additional noninvasive check-up to read pre-cancerous polyps and colon tumors appears to be more accurate than advised noninvasive tests such as the fecal occult blood test, Mayo clinic researchers say. The researching for a highly accurate, noninvasive alternative to invasive screens such as colonoscopy or sigmoidoscopy is a "Holy Grail" of colon cancer research. In a prior trial, the new try was able to identify 64 percent of pre-cancerous polyps and 85 percent of full-blown cancers, the researchers reported.

Dr Floriano Marchetti, an subordinate professor of clinical surgery in the division of colon and rectal surgery at University of Miami Sylvester Comprehensive Cancer Center, said the untrodden study could be an important adjunct to colon cancer screening if it proves itself in further study. "Obviously, these findings requisite to be replicated on a larger scale. Hopefully, this is a good start for a more reliable test".

Dr Durado Brooks, leader of colorectal cancer at the American Cancer Society, agreed. "These findings are interesting. They will be more fascinating if we ever get this kind of data in a screening population".

The study's lead researcher remained optimistic. "There are 150000 rejuvenated cases of colon cancer each year in the United States, treated at an estimated price of $14 billion," noted Dr David A Ahlquist, professor of c physic and a consultant in gastroenterology at the Mayo Clinic in Rochester, Minn. "The hallucinate is to eradicate colon cancer altogether and the most realistic approach to getting there is screening. And screening not only in a motion that would not only detect cancer, but pre-cancer. Our test takes us closer to that dream".

Ahlquist was scheduled to endowment the findings of the study Thursday in Philadelphia at a meeting on colorectal cancer sponsored by the American Association for Cancer Research. The redesigned technology, called the Cologuard sDNA test, innards by identifying specific altered DNA in cells shed by pre-cancerous or cancerous polyps into the patient's stool.

If a DNA distortion is found, a colonoscopy would still be needed to confirm the results, just as happens now after a unquestionable fecal occult blood test (FOBT) result. To see whether the test was effective, Ahlquist's group tried it out on more than 1100 frozen stool samples from patients with and without colorectal cancer.

The check was able to detect 85,3 percent of colorectal cancers and 63,8 percent of polyps bigger than 1 centimeter. Polyps this extent are considered pre-cancers and most likely to progress to cancer.
