According to a recent study, screening for colorectal cancer can & # 39; & # 39 has; benefit male patients, while similar benefits not found among women.
The study appeared in the British Journal of Surgery. The colorectal cancer is the third most common form of & # 39; cancer in the world. Every year, about 3,000 new cases are diagnosed, and about 1,200 patients die from it.
Between 2004 and 2016, has become & # 39; extensive screening program in Finland, with a view to study the benefits and potential pitfalls of & # 39; widespread screening across the country for colorectal cancer.
The study was aimed at people & # 39; between 60 and 69 years, and slightly less than half the group & # 39; age, or slightly more than 300,000 people, were randomized to late 2011. From the study population was invited to screening, while the other half group & # 39; age served as group & # 39; control. of occult blood in feces Tests (FOBT) used in screening, and patients who have a positive test for blood were referred for colonoscopy.
The first study based on screening results indicated no significant reduction in mortality, so the tests are not founded after 2016. However, researchers from the University Hospital & # 39; Helsinki and the Finnish Cancer Registry wanted to examine whether screening benefits offered to patients & # 39; colorectal cancer.
"Virtually no cancer tests were found to have an impact on overall mortality. However, they can still be useful in & # 39; other ways. We wanted to studying whether patients can avoid the more intense treatments if they participated in screening for colorectal cancer "said Dr. Laura Koskenvuo.
The study examined data of & # 39; approximately 1400 patients diagnosed with colorectal cancer. The results indicated that among the patients from group & # 39; screening, the surgical removal of & # 39; Full tumor was more common than it was a success among the patients in the group & # 39; control, and were less likely to require chemotherapy. Patients from group & # 39; screening were also less likely to undergo surgery & # 39; emergency because their tumor patients group & # 39; control.
"The group & # 39; control had 50 percent more surgeries & # 39; emergency, 40 percent more incomplete absorption tumors and 20 percent more treatments & # 39; chemotherapy than patients -grupp of & # 39; screening ", said Professor Additional Ville Sallinen, gastrointestinal surgeon.
Closer inspection of the results showed that these benefits were particularly prevalent among male patients. Not found similar benefits for women.
In addition, the researchers found that screening was most efficient to identify the cancer left colorectal cancer and screening found that it had no benefit for patients & # 39; cancer on right, possibly because the blood arising & # 39; tumor on the right side becomes so diluted travels through the colon that can not detect gFOBT.
"In the future, we examine whether different techniques & # 39; screening can improve the situation & # 39; female patients and facilitate the diagnosis of & # 39; colon cancer and right," said this researchers.
