[A scanning method for detecting colorectal tumors].
OBJECTIVE
To develop a method for survey of colorectal tumors.


METHODS
Mucus obtained by digital rectal examination was smeared on a slice to react with peanut agglutinin labeled by Horseradish-peroxidase.


RESULTS
Brown color was noted in positive reaction. In detecting colorectal tumors, the sensitivity and specificity of the method was 88.2% and 92.5% respectively.


CONCLUSIONS
The method is effective in detecting colorectal tumors in humans.
