Cervicovaginal smears from 2 women with postirradiation dysplasia, 4 women with postirradiation squamous cell carcinoma of the cervix, 30 women with irradiation atypia and 5 healthy, nonirradiated women were stained immunohistochemically with six keratin antibodies. For four of the antibodies--CK19 (BA17), EMA, PKK-1 and CAM 5.2--squamous cells showing irradiation atypia, postirradiation dysplasia or postirradiation squamous cell carcinoma were more likely to stain positively than were nonirradiated squamous cells. For three of the antibodies in which multiple squamous cells stained positively, the proportion of squamous cells showing postirradiation dysplasia or postirradiation squamous cell carcinoma staining strongly was equal to or greater than the corresponding overall proportion for squamous cells showing irradiation atypia. This was statistically significant with only one antibody, PKK-1. No statistically significant differences were seen in staining of irradiated and nonirradiated squamous cells by MAK-6 and AE1:AE3. The data show that some keratin antigens are more often expressed in the irradiated groups and that there may be differences in the degree of antigen expression between squamous cells showing postirradiation dysplasia or postirradiation squamous cell carcinoma and squamous cells showing irradiation atypia.
