New Screening Combo For Colorectal Cancer

New Screening Combo For Colorectal Cancer
Stool testing for blood in the stool is getting more sophisticated. A new study has shown that use of a simple immunochemical fecal occult blood test (FOBT), in combination with the traditional guaiac FOBT is capable of accurately detecting colorectal cancer and may reduce the need for more complex and less pleasing procedure of invasive colonoscopy.

These findings are published in the recent issue of the journal Lancet Oncology.

While guaiac FOBT, which detects blood in the feces, is inexpensive and relatively easy to do, it's not very accurate and has low clinical sensitivity and specificity, because cancer is not the only cause of blood in feces, the British researchers noted. People who test positive on guaiac FOBT have a follow-up colonoscopy, which is a more expensive procedure and carries some risks, the study authors added.

Researchers propose that people who have weak or moderate positive guaiac FOBT results have a follow-up immunochemical FOBT to identify those who would be less likely to have cancer and not require a colonoscopy.

Beckman Coulter is one amongst several other companies that has introduced improved products called fecal immunochemical tests or FIT. These products are being recognized by the medical world as a more reliable way of detecting cancer and the polyps, which have the chances of developing into cancer.
