IMMUNE-CHEMICAL OCCULT BLOOD FECES ANALYSIS AT GASTRIC CARCINOMA SCREENING

Gastric carcinoma has been one of the most urgent problems of the contemporary medicine. Annually, about 800 thousand new cases and 628 thousand deaths from the disease are registered. The highest survival rate is registered in Japan - 53%, in other countries it does not exceed 15-20%. The success in survival improvement in Japan belongs to the mass screening of the population and adopted national cancer programs. But even in Japan screening with the help of esophagogastroduodenoscopy and x-ray of a stomach is problematic as it does not meet WHO demands. Both tests are difficult enough, invasive to a known degree and have a significant amount of false-negative results. We have examined 43 patients with gastric cancer, 36 patients with gastroduodenal ulcers and 27 patients with gastric dyspepsia aged 17-80 (average age 45±6,82 years old). The aim of the present investigation was to study the diagnostic precision of the contemporary immune-chemical fecal occult blood tests as a screening method in the diagnostics of gastric cancer. It has been defined that positive fecal occult blood tests are observed at gastric cancer than at other pathology of this organ (p<0.05). Yet, immune-chemical fecal occult blood test is less effective than hemoccult test by its operative performances of the diagnostic method which makes it inappropriate for gastric cancer diagnostics.
