A GUAIAC PROBE AND AN IMMUNE MARKER TEST FOR HIDDEN BLOOD IN FAECES IN AN UNINVASIVE CANCER DIAGNOSTIC OF A GASTROINTESTINAL TRACT

Abstract

The aim of an investigation was to study the diagnostic possibilities of various methods for revelation of hidden blood in faeces in an uninvasive cancer diagnostic of a gastrointestinal tract. The material and methods of the investigation: we have examined 43 patients diseased with a stomach cancer, 36 patients diseased with the gastro duodenal ulcers, 27 patients diseased with a stomach dyspepsia, 58 patients diseased with a colorectal cancer, 37 patients diseased with the bowels polyps, 57 patients diseased with a bowels stimulation syndrome and 26 healthy volunteers. Blood loss from a gastrointestinal tract determined by using the guaiac probe and immune marker test for hidden blood in faeces. The results of the investigation are: the immune marker test for hidden blood in faeces exceeds a hemoccult-test at a sensitiveness in revelation of the colorectal cancer (p < 0,05). It’s sensitiveness is quite high and makes up 93,8%. The hemoccult-test exceeds the immune marker test for hidden blood in faeces in revelation of the stomach cancer not only by the sensitiveness but a specific that is really important for the uninvasive test though in our investigation this tendency is not achieve a statistical meaning (p < 0,05). At that time according to our data the specific of the hemoccult-test in revelation of the stomach cancer is sufficiently high and makes 88,9%.
