Isoantigen ABH in cervical intraepithelial neoplasia.

ABSTRACT

The purpose of the study was to examine the relationship between the histologic findings and the presence or absence of ABH isoantigens in intraepithelial neoplasia of the cervix. After the lesions were graded by four pathologists, the Red Cell Adherence (RCA) test was done to demonstrate the ABH antigens, and the results of the two were compared. The correlation between the morphologic diagnosis and the results of the RCA test was limited. The percentages of tissues giving positive (+) or positive-negative (+/-) reactions were very similar in intraepithelial neoplsia (59.2%) and normal squamous epithelium (58.4%). The relationship of the RCA test results and behavior of the lesion was not studied.
