The Value of Cytology in the Diagnosis of Colonic Cancer
Cytology is a well-established diagnostic method in gastric malignancy. We have prospectively investigated the value of this method in a previous study in 1976. The diagnostic yield of brush cytology was similar to that of multiple biopsies, with a sensitivity of 85% vs 83%. At 96%, the cumulative accuracy obtained with both methods was significantly higher; a few false-negative results with one method were compensated by positive results with the other.
